1 Overview
The HP 9000 rp7420 server is a member of the HP business-critical computing platform family.
It is a mid-range, mid-volume server, positioned as an upgrade to the HP 9000 rp7410 server in the PL-1X product line. The HP 9000 rp7420 server shares the same hardware as the HP 9000 rp7410 server with changes to the cell board, CPU modules, core I/O, and the PCI-X backplane.
The HP 9000 rp7420 server provides increased performance over its predecessor.
Introduction
The HP 9000 rp7420 server is a 10U, 8-socket symmetric multi-processing, rack-mounted server that accommodates up to 64 GB of memory; PCI-X I/O, and internal peripherals, including disks and DVD/tape. Its high availability features include N+1 hot-pluggable fans and power, redundant power cords, and hot-pluggable PCI-X cards and internal disks. It currently uses dual core,
PA-RISC processors.
Figure 1-1 HP 9000 rp7420 server (front view)
Introduction 17
Figure 1-2 HP 9000 rp7420 server (without front bezel)
System Backplane
The system backplane is comprised of the system clock generation logic, the system reset generation logic, DC-to-DC converters, power monitor logic, and two Local Bus Adapter (LBA) link-to-PCI converter ASICs. It also includes connectors for attaching the cell boards, the PCI-X backplane, Management Processor (MP) Core I/O MP/SCSI boards, SCSI cables, bulk power, chassis fans, the front panel display, intrusion switches, and the system scan card. Unlike the
Superdome or rp8400 servers, there are no Crossbar Chips (XBC) on the system backplane. The
“crossbar-less” back-to-back Cell Controller (CC) connection increases performance and reduces costs.
Only half of the MP Core I/O board set connects to the system backplane. The MP/SCSI boards plug into the backplane, while the LAN/SCSI boards plug into the PCI-X backplane.
18 Overview
Figure 1-3 System Backplane Block Diagram
System Backplane to PCI-X Backplane Connectivity
The PCI-X backplane uses two connectors for the System Bus Adapter (SBA) link bus and two connectors for the high speed data signals and the manageability signals.
SBA link bus signals are routed through the system backplane to the CC on each corresponding cell board.
The high speed data signals are routed from the SBA chips on the PCI-X backplane to the two
LBA PCI bus controllers on the system backplane.
Clocks and Reset
The system backplane contains reset and clock circuitry that propagates through the whole system. The central clocks drive all major chip set clocks. Therefore, these circuits represent a system-wide single point of failure.
I/O Subsystem
The cell board to the PCI-X board path runs from the CC to the SBA, from the SBA to the ropes, from the ropes to the LBA, and from the LBA to the PCI slots seen in
. The CC on cell board 0 and cell board 1 each communicate with individual SBAs over the SBA link. The SBA link consists of both an inbound and an outbound link with an effective bandwidth of approximately 1 GB/sec. The SBA converts the SBA link protocol into “ropes.” A rope is defined as a high-speed, point-to-point data bus. The SBA can support up to 16 of these high-speed bi-directional rope links for a total aggregate bandwidth of approximately 4 GB/sec. Each LBA acts as a bus bridge, supporting either one or two ropes and capable of driving 33 Mhz or 66
Mhz for PCI cards. The LBAs can also drive at 66 Mhz or 133 Mhz for PCI-X cards.

The PCI-X backplane is the primary I/O interface for HP 9000 rp7420 servers. It provides sixteen
64-bit, hot-plug PCI/PCI-X slots. Fourteen of the slots have dual ropes connected to the LBA chips. The remaining two slots have a single rope connected to each LBA chip. Each of the sixteen slots are capable of 66 MHz/33 MHz PCI or 133 MHz/66 MHz PCI-X. All sixteen PCI slots are keyed for 3.3-volt connectors (accepting both Universal and 3.3-V cards). The PCI-X backplane does not provide any 5-volt slots for the I/O cards. For more details, see
The PCI-X backplane is physically one board but behaves like two independent partitions. SBA
0 and its associated LBAs and eight PCI-X slots form one I/0 partition. SBA 1 and its associated
LBAs and eight PCI-X slots form the other I/0 partition. One I/O partition can be powered down separate from the other I/O partition.

Cell Board
The cell board contains several hardware blocks connected by several data buses. The major hardware blocks are the Central Processor Units (CPUs), the Cell Controller, the Memory
Controllers, and the Memory. Minor hardware blocks include Clock Distribution, Power
Distribution, Reset Circuit, and Platform Dependent Hardware (PDH) Riser Board Interface. The buses include two Front Side Buses (FBS0 and FBS1), a Memory (MID) bus, a Crossbar (XB) bus, and an I/O bus. All these blocks come together at the CC chip.
Figure 1-6 Cell Board
The HP 9000 rp7420 server has a 48-V distributed power system and receives the 48-V power from the system backplane board. The cell board contains DC-to-DC converters to generate the required voltage rails. The DC-to-DC converters on the cell board do not provide N+1 redundancy.
Because of space limitations on the cell board, the PDH/PDHC circuitry resides on a riser board that plugs into the cell board at a right angle. The cell board also includes clock circuits, test circuits, and de-coupling capacitors.
shows a simplified view of the memory subsystem. It consists of two independent access paths, each path having its own address bus, control bus, data bus, and DIMMs . In practice, the CC runs the two paths 180 degrees out of phase with respect to each other to facilitate pipelining in the CC. Address and control signals are fanned out through register ports to the synchronous dynamic random access memory (SDRAM) on the DIMMs.
22 Overview
Figure 1-7 Memory Subsystem
PDH Riser Board
The Platform Dependant Hardware Riser board is a daughter card for the cell board. It contains a micro-processor memory interface microcircuit, processor-dependent hardware including the processor-dependent code (PDC), flash memory, and a manageability microcontroller, called the Platform Dependant Hardware Controller (PDHC) with associated circuitry. The PDH obtains cell board configuration information from cell board signals and from the LPM on the cell.
The PDH riser board contains circuitry that the cell board requires to function and, therefore, each cell board must have a PDH riser installed before it is added to a server.
Central Processor Units
The cell board can hold up to eight (four dual-core) CPUs and can be populated with CPUs in increments of two CPUs. On a cell board, the processors must be the same type and speed. Two
CPUs is the minimum configuration allowed on the HP 9000 rp7420 server. There are two
Frontside Buses (FBS), one for sockets 0 and 1, and one for sockets 2 and 3. Each FBS must have either a CPU or a terminator at the end of the bus or the board does not operate properly. There cannot be a terminator board in socket 1 or socket 3 locations. For the CPU load order that must be maintained when adding CPUs to the cell board, see
Table 1-2 . For the locations on the cell
board for installing CPUs, see

DIMMs
Custom designed by HP, each DIMM contains 36 x 4 SDRAM memory components similar to
PC-133 memory, but qualified to run at 125 MHz. They have a low-voltage TTL interface. The
CEC does not support traditional DRAMs.
The HP 9000 rp7420 server supports DIMMs with 256 MB, 512, MB, 1 GB, and 2 GB capacity.
Table 1-3 shows each DIMM supported with its associated capacity, the resulting total system
capacity, and the memory component density.
DIMMs must be loaded in sets of two at specific locations. For best performance, HP recommends loading sets of eight DIMMs.

24 Overview
Main Memory Performance
Latency to main memory is an important parameter in determining overall system performance.
With memory buses running at 125 MHz, the latency for a page hit is 8.5 cycles (68 ns), the latency for a page closed is 11.5 cycles (92 ns), and the latency for a page miss is 14.5 cycles (116 ns).
Valid Memory Configurations
The HP 9000 rp7420 server is capable of supporting as little as 0.5 GB of main memory using two
256 MB DIMMs installed on a single cell board and as much as 128 GB by filling all 16 DIMM slots on both cell boards with 4 GB DIMMs.
DIMMs must be loaded in sets of two at specified locations on the cell board. Two DIMMs are called a rank; two ranks would be equivalent to four DIMMs, three ranks would be six DIMMs, and so on. The DIMMs must be the same size in a rank. The DIMMs across all cells in a partition should have identical memory loaded.
shows the DIMM slot layout on the cell board.
For DIMM load order, see
.
A quad seen in
is a grouping of four DIMMs. Configurations with 8 or 16 DIMM slots loaded are recommended. The DIMM sizes in a quad can be different but the DIMMs in a rank must be the same size.

Cells and nPartitions
A cell board that has an I/O link to a bootable device and a console (usually supplied by an MP core I/O card) is a potential boot cell. The cell that contains the boot console I/O path is the called the root cell. Both cells are potential root cells. The primary or default root cell in a single nPartition system is the bottom cell (cell 1).
An nPartition (also called a Protection Domain) is a cell or cells running the same operating system and sharing processes and memory space among the components. Each nPartition must have one root cell and can contain both cells. The HP 9000 rp7420 server has only two possible nPartition configurations: single or dual. The additional cell that can be part of the nPartition does not require I/O links or MP core I/O cards.
In the single nPartition case, if two cells are present, either cell can be the root cell, assuming both cells have MP core I/O functionality present. If only one cell is present, that cell is the root cell (and should be cell 1).
In the dual nPartition case (two cells required), each nPartition consists of one cell, and each cell must be a root cell. The ability to interconnect two cells in one nPartition or isolate the cells in a dual nPartition system provides system configuration flexibility. System partitioning is configured by the system MP.
NOTE: Partition configuration information is available on the HP website at http:// docs.hp.com
. For more detail, see the HP Systems Partition Guide: Administration for nPartitions.
Internal Disk Devices for the HP 9000 rp7420 server
In an HP 9000 rp7420 server, the top internal disk drives connect to cell 1 through the core I/O for cell 1. Both of the bottom disk drives connect to cell 0 through the core I/O for cell 0.
The CD/DVD/DAT drive connects to cell 1 through the core I/O card for cell 1.
26 Overview
Figure 1-10 Internal Disks
MP/SCSI MP Core I/O Board
The HP 9000 rp7420 server accommodates two sets of MP Core I/O functionality. Each MP/SCSI core I/O board set consists of a MP/SCSI board and a Procurium LAN/SCSI board. At least one
MP/SCSI board is required (independent of partitions). An additional MP/SCSI board can be added as well (and is required in a dual partition system). Both MP/SCSI boards are oriented vertically and plug into the system backplane. The MP/SCSI board incorporates a dual channel
Ultra160 SCSI controller.
Procurium LAN/SCSI Board
At least one Procurium LAN/SCSI board is required for the minimum system configuration; two are required in a dual partition system. The Procurium board is a standard PCI form factor card with PCI card edge connectors. The PCI-X backplane has one slot location reserved for the required Procurium board and another that can accommodate either a Procurium board or any other supported add-in PCI-X card. The Procurium board is hot-pluggable.
Mass Storage (Disk) Backplane
Internal mass storage connections (to disks) are routed on the mass storage backplane, having connectors and termination circuitry. All disks are hot-pluggable. The HP 9000 rp7420 server accommodates one internal, removable media device. Therefore, only one power connector for a removable media device is required on the mass storage backplane. The mass storage backplane incorporates a circuit that enables power to the internal removable media device to be programmatically cycled.

Server Description
Dimensions
The dimensions of the HP 9000 rp7420 server are as follows:
• Width: 44.45 cm (17.5 inches), constrained by EIA standard 19 inch racks
• Depth: Defined by cable management constraints to fit into standard 36-inch deep racks
(Rittal/Compaq, Rosebowl I):
25.5 inches from front rack column to PCI connector surface
26.7 inches from front rack column to MP Core I/O connector surface
30 inches overall package dimension, including 2.7 inches protruding in front of the front rack columns
• Height: 10U – 0.54 cm = 43.91 cm (17.287 inches). This is the appropriate height for a product that consumes 10U of rack height while allowing adequate clearance between products directly above and below this product. Fitting four server units per 2 m rack and upgrade of current 10U height products in the future are the main height constraints.
System Chassis
The mass storage section located in the front enables access to removable mass storage devices without removal of the bezel (not shown). This is especially helpful when the system is mounted in the lowest position in a rack. The mass storage bay accommodates one 5.25-inch removable media device and up to four 3.5-inch hard drives. The front panel display board, containing
LEDs and the system power switch, is located directly above the 5.25-inch removable media bay.
Below the mass storage section and behind a removable bezel are two PCI DC-to-DC power converters.
The BPS section is partitioned by a sealed metallic enclosure located in the bottom of the package.
This enclosure houses the N+1 fully redundant BPS.
28 Overview
Figure 1-11 Right-Front View of HP 9000 rp7420 server
The PCI-X card section, located toward the rear, is accessed by removing the top cover.
The PCI OLR fan modules are located in front of the PCI-X cards. These six 9.2-cm fans are housed in plastic carriers. They are configured in two rows of three fans.
The MP/SCSI MP core I/O boards are positioned vertically at the rear of the chassis.
The PCI-X card bulkhead connectors are located in the top rear portion of the chassis.
Four OLR system fan modules, externally attached to the chassis, are 15-cm (6.5-inch) fans. Two fans are mounted on the front surface of the chassis and two are mounted on the rear surface.
The two hot-pluggable N+1 redundant BPS provide a wide input voltage range. They are installed in the front of the chassis, directly under the front fans.
A cable harness that connects from the rear of the BPSs to the system backplane provides DC power distribution.
Access the system backplane by removing the left side cover. The system backplane inserts by a guide/insertion mechanism using a single large jack screw assembly.
SCSI ribbon-cable assemblies route from the mass storage area to the backside of the system backplane and to the Procurium PCI MP core I/O card.
Access the cell boards from the right side of the chassis behind the removable side cover.

2 Unpacking the Server
HP shipping containers are designed to protect their contents under normal shipping conditions.
After the equipment arrives, carefully inspect each carton for signs of shipping damage. A tilt indicator is installed on each carton shipped. The beads in the indicator roll to the upper position if the container was tilted to an angle that could cause equipment damage. The tilt indicator itself has two windows, and each window, under normal conditions, shows four beads present. If a carton was mishandled or accidentally dropped, the tilt indicator indicates missing beads. If damage is found, document the damage with photographs and contact the transport carrier immediately.
Examine the server cabinet for visible shipping damage. After unpacking the cabinet, check for damage that might have been obscured by the shipping container. If damage is found after visual inspection, document the damage with photographs and contact the transport carrier immediately.
If the equipment has any damage, a damage claim form must be obtained by the customer from the shipping representative. The customer should complete the form and return it to the shipping representative.
NOTE: The server might come already racked or ready for rack installation.
Unpacking a Racked Server
This section contains information about unpacking the cabinet.
WARNING!
Wear protective glasses while cutting the plastic bands around the shipping container. These bands are under tension. When cut, they can spring back and cause serious eye injury.

Installing PCI I/O Cards
HP 9000 rp7420 servers implement manual release latch (MRL) hardware for use in online add or replacement (OLAR) operations. If an MRL is left open while the server is booting, HP-UX can incorrectly cache PCI slot power status causing OLAR operations to fail. To prevent this situation, ensure all the MRLs are closed before booting the server.
If OLAR reports that a slot is present and powered off, but no OLAR operations to turn power on to that slot have succeeded even after the MRL is closed, the MRL may have been left open during boot. To clear this condition, close the MRL for the PCI slot then power off the PCI slot using the rad -o command. This will allow future OLAR operations to succeed on this PCI slot.
IMPORTANT: PCI I/O card installation procedures should be downloaded from the HP website at http://docs.hp.com
. Background information and procedures for adding a new PCI I/O card using online addition are found in the Interface Card OL* Support Guide.
Prerequisites for Adding a PCI I/O Card Using the Attention Button
The prerequisites for this procedure are:
• Drivers for the card have already been installed.
• There are no drivers associated with the slot.
• The green power LED is steady Off.
Should the empty slot be in the On state, use the olrad command or the pdweb tool to power off the slot.
• The yellow attention LED is steady Off or is blinking (if a user has requested the slot location).
• For details on card installation, see the host bus adapter (HBA) documentation.
PCI-X Card Cage Assembly I/O Cards 47
• To determine the status of all the PCI I/O slots, run the olrad -q command.
• Obtain a copy of the interface card guide for instructions on preparing the operating system for the online addition of the PCI I/O card before attempting to insert a PCI I/O card into the PCI-X card cage assembly backplane slot.
CAUTION: Observe all ESD safety precautions before attempting this procedure. Failure to follow ESD safety precautions could result in damage to the server.
This procedure describes how to perform an online addition of a PCI card using the attention button for cards whose drivers support OLAR. The attention button is also referred to as the doorbell.
To add a PCI I/O card, follow these steps:
1.
Remove the top cover.
2.
Remove the PCI bulkhead filler panel.
3.
Flip the PCI MRL for the card slot to the open position. See
4.
Install the new PCI card in the slot.
NOTE: Apply a slow, firm pressure to the card to properly seat it into the backplane.
5.
Flip the PCI MRL for the card slot to the closed position.
CAUTION: Working out of sequence or not completing the actions within each step could cause the system to crash.
Do not press the attention button until the latch is locked.
6.
Press the attention button.
The green power LED starts to blink.
Figure 3-8 PCI I/O Slot Details
7.
Wait for the green power LED to stop blinking and remain solid green.
48 Installing Accessories
8.
Check for errors in the hotplugd daemon log file (default: /var/adm/hotplugd.log).
The critical resource analysis (CRA) performed while doing an attention button initiated add action is very restrictive and the action will not complete—it will fail—to protect critical resources from being impacted. For finer control over CRA actions use pdweb or the olrad command. See the Interface Card OL* Support Guide located on the Web at http:// docs.hp.com
for details.
9.
Replace the top cover.
10. Connect the cables to the installed PCI card.

4 Cabling and Powering the Server
After you have unpacked the server and moved into position, you must be connect it to an AC power source. Check the AC power for the proper voltage before you power the system on. This chapter describes these activities.
AC Input Power
The server has the following line-cord configurations:
• All four line cords (preferred configuration)
• Cords A0 and A1 only
• Cords B0 and B1 only
• Cords A0 and B0 only
• Cords A1 and B1 only
A single-line-cord configuration is not allowed.
Figure 4-1 Power Cord Configuration
The power cord configuration is passed to the operating system using the pwrgrd (Power Grid) command. Each of the five selections in the pwrgrd command matches one of the configurations.
The appropriate option should be selected for the actual line cord configuration. With the correct configuration selected, the LEDs should be green. When the pwrgrd command is invoked, the following menu displays: prompt> pwrgrd
Power grid configuration preference.
1. Grid A only (Cords A0,B0 required)
2. Grid B only (Cords A1,B1 required)
3. Grids A & B (Cords A0,A1,B0,B1 required)
4. Cords A0 & B0 only5. Cords A1 & B1 only
Select Option:
If two separate power sources are available, the two power supplies can be plugged into the separate power sources, increasing system reliability should one power source fail.
AC Input Power 51
Figure 4-2 Power Source versus Power Distribution
WARNING!
Voltage is present at various locations within the server whenever a power source is connected. This voltage is present even when the main power switch is in the OFF position.
To completely remove power, all power cords must be removed from the server. Failure to observe this warning can result in personal injury or damage to equipment.
NOTE: System firmware prevents boot when a single power cord configuration is detected.
Checking the Voltage
This section provides voltage check information for use on the customer site. The emphasis focuses on measuring the voltages at the power cord plug end specified as an IEC 320 C19 type plug. This end plugs directly into the back of the HP 9000 rp7420 server chassis.
NOTE: Perform these procedures for each power cord to be plugged directly into the back of the HP 9000 rp7420 server. If you do not get the expected results from this voltage check, see
“Checking the Voltage (Additional Procedure)” (page 54)
.
Verifying the Voltage Range of the Receptacle
This measures the voltage between L1 and L2, L1 to ground, and L2 to ground. Three separate measurements are performed during this procedure. For voltage reference points when performing the measurements, see
.
52 Cabling and Powering the Server
Figure 4-3 Voltage Reference Points for IEC 320 C19 Plug
IMPORTANT: Perform the following measurements for every power cord that plugs into the
HP 9000 rp7420 server.
1.
Measure the voltage between L1 and L2. This is considered to be a phase-to-phase measurement in North America. In Europe and certain parts of Asia-Pacific, this measurement is referred to as a phase-to-neutral measurement. The expected voltage measured should be between 200–240 VAC regardless of the geographic region.
2.
Measure the voltage between L1 and ground. In North America, verify this voltage is between
100–120 VAC. In Europe and certain parts of Asia-Pacific, verify this voltage is between
200–240 VAC.
3.
Measure the voltage between L2 and ground. In North America, verify this voltage is between
100–120 VAC. In Europe and certain parts of Asia-Pacific, verify this voltage is 0 (zero) VAC.

Verifying the Safety Ground
This measures the voltage level between B0 and A0. The measurement is taken between ground pins of the two power cords. For ground reference points when performing this measurement, see
Checking the Voltage 53
Figure 4-4 Safety Ground Reference Check
To measure the voltage, follow these steps:
1.
Measure the voltage between B0 and A0. Take the AC voltage down to the lowest scale on the volt meter.
2.
Insert one probe into the ground pin for B0.
3.
Insert the other probe into the ground pin for A0.
4.
Verify that the measurement is between 0–5 V AC. If the measurement is 5 V or greater, escalate the situation. Do not attempt to plug the power cords into the HP 9000 rp7420 server.
Checking the Voltage (Additional Procedure)
The voltage check ensures that all phases (and neutral, for international systems) are connected correctly to the cabinet and that the AC input voltage is within limits.
This procedure must be performed if the previous voltage check procedure did not yield the expected results as previously outlined.
NOTE: If a UPS is used, see the applicable UPS documentation for information to connect the server and to check the UPS output voltage. UPS user manual documentation is shipped with the UPS. Documentation can also be found at http://www.hp.com/racksolutions .

MP Core I/O Connections
Each HP 9000 rp7420 server can have up to two MP core I/O board sets installed. Which allows two partitions to operate, or MP core I/O redundancy in a single partition configuration. Each
MP core I/O board set consists of two boards: the MP/SCSI board and the LAN/SCSI board. The
MP/SCSI board is oriented vertically and accessed from the back of the server. The LAN/SCSI is accessed from the PCI/PCI-X expansion card bay. Only the primary MP core I/O board set
(MP/SCSI slot 1 and LAN/SCSI slot 8, chassis 1) is required for a single partition implementation.
The secondary MP/SCSI board is not necessary for full operation. However, without the secondary
MP/SCSI board, only two internal disks can be accessed.
MP/SCSI Connections
The MP/SCSI board is required to update firmware, access the console, turn partition power on or off, access all but two of the internal peripherals, and use other features of the server.
Connections to the MP/SCSI board include the following:
MP Core I/O Connections 55
• DB25 connector, by way of the M cable
This RS-232 connector provides connections for a local console, external modem, and a UPS.
The server end of the M cable terminates in a DB25 connector. The opposite side of the cable terminates in three DB9 connectors labeled CONSOLE, UPS, and REMOTE.
• 10/100 Base-T LAN RJ45 connector (for LAN and web console access).
This LAN uses standby power and is still active if the front panel power switch is off and
AC is present.
• Internal LVD Ultra 160 SCSI channel for connections to internal mass storage
• Internal SE Ultra SCSI channel for connection to an internal removable media device.
LAN/SCSI Connections
The LAN/SCSI board is a PCI form factor card that provides the basic external I/O connectivity for the system.
Connections to the LAN/SCSI board include the following:
• PCI-X to PCI-X bridge for multi-device compatibility.
• Internal LVD Ultra 160 SCSI channel for connections to internal mass storage.
• External LVD Ultra 160 SCSI channel connected to a 68-pin VHDCI connector.
• 10/100/1000 Base-T LAN RJ45 connector.
The primary LAN interface is located on the LAN/SCSI board installed in the right-most slot when viewing the system from the back.
Management Processor Access
NOTE: To access the MP for the initial installation, you must first connect the M cable to the
DB25 connector located on the primary MP/SCSI board. The primary MP/SCSI board is located in the lower MP/SCSI board slot.
Setting Up the Customer Engineer Tool (PC)
The Customer Engineer (CE) Tool is usually a laptop. It enables communication with the MP in the HP 9000 rp7420 server. The MP monitors the activity of either a one partition or a multiple-partition configuration.
During installation, communicating with the MP enables such tasks as:
• Verifying that the components are present and installed correctly
• Setting LAN IP addresses
• Shutting off cell board power
Communication with the MP is established by connecting the CE Tool to the local RS-232 port on the MP Core I/O card.
Setting CE Tool Parameters
After powering on the CE Tool, ensure the communications settings are as follows:
• 8/none (parity)
• 9600 baud
• na (Receive)
• na (Transmit)
If the CE Tool is a laptop using Reflection, ensure communications settings are in place by following these steps:
1.
From the Reflection Main screen, pull down the Connection menu and select Connection
Setup.
56 Cabling and Powering the Server
2.
Select Serial Port.
3.
Select Com1.
4.
Check the settings and change, if required.
Go to More Settings to set Xon/Xoff. Click OK to close the More Settings window.
5.
Click OK to close the Connection Setup window.
6.
Pull down the Setup menu and select Terminal (under the Emulation tab).
7.
Select terminal type VT100.
8.
Click Apply.
This option is not highlighted if the terminal type you want is already selected.
9.
Click OK.
Connecting the CE Tool to the Local RS-232 Port on the MP
This connection allows direct communications with the MP. Only one window can be created on the CE Tool to monitor the MP. When enabled, it provides direct access to the MP and any partition.
To connect the CE Tool to the Local RS-232 port on the MP, follow these steps:
1.
Connect one end of a null modem cable (9-pin to 9-pin) (Part Number 5182-4794) to the M cable connector labeled CONSOLE.
2.
Connect the other end of the RS-232 cable to the CE Tool.
Standby Power and Logging In to the MP
After connecting the serial device, it is possible to log in to the Management Processor (MP).
Housekeeping power (also known as standby power) is generated as soon as AC power is applied to the server. Because the MP uses standby power, it is possible to log in to the MP even when the power switch is in the OFF position. The power switch is a DC power switch that controls
+48 V DC.
Before powering up the HP 9000 rp7420 server for the first time, follow these steps:
1.
Verify that the AC voltage at the input source is within specifications for each server being installed.
2.
If not already done so, power on the serial display device.
The preferred tool is the CE Tool running Reflection.
To power up the MP, set up a communications link, and log in to the MP, follow these steps:
1.
Connect the server to AC power.

NOTE: If the partition fails to boot or if the server was shipped without Instant Ignition, booting from a DVD that contains the operating system and other necessary software might be required.
Adding Processors With Instant Capacity On Demand
The Instant Capacity On Demand (iCOD) program provides access to additional CPU resources beyond the amount that was purchased for the server. This provides the ability to activate additional CPU power for unexpected growth and unexpected spikes in workloads. Internally, iCOD systems physically have more CPUs, called iCOD CPUs, than the number of CPUs actually purchased. These iCOD CPUs reside in the purchased system, but they belong to HP and therefore are HP assets. A nominal “Right-To-Access Fee” is paid to HP for each iCOD processor in the system. At any time, any number of iCOD CPUs can be “activated.” Activating an iCOD CPU automatically and instantaneously transforms the iCOD CPU into an instantly ordered and fulfilled CPU upgrade that requires payment. After the iCOD CPU is activated and paid for, it is no longer an iCOD CPU, but is now an ordered and delivered CPU upgrade for the system.
The most current information on installing, configuring, and troubleshooting iCOD can be found at http://docs.hp.com
.
NOTE: You need to be aware of the iCOD email requirements. For further details, see http:// docs.hp.com

5 Troubleshooting
This chapter contains information about the various status LEDs on the HP 9000 rp7420 server and other troubleshooting information.
Common Installation Problems
The following sections contain general procedures to help you locate installation problems.
CAUTION: Replace the top cover before operating the server, even for a short time. Otherwise, overheating can damage chips, boards, and mass storage devices. However, you can safely remove the PCI access panel while the server is running to remove and replace PCI hot-plug cards. For any other service activity requiring access to the processor baseboard or I/O backplane, power the server off, and observe all safety precautions.
Most problems are the result of incorrect system and SCSI subsystem configurations.
To troubleshoot an installation problem, perform the following checks in the order given:
1.
Check all cable and power connections, including those in the rack, and so on.
2.
Ensure the server is configured properly.
Check the Setup Utility. If the error is a network-related problem, determine if the server has enough memory and hard disk drive capacity.
3.
Verify all cables and boards are securely plugged in to the appropriate connectors or slots.
4.
Remove all extra options, such as disk drives, one at a time, checking the affect of each on the server.
5.
Unplug the power cords, wait 20 seconds, plug-in the power cords and restart the server.
6.
If a hardware error is suspected, follow these steps: a.
Log users off the LAN and power off the server.
b.
Extend the server out of the rack and remove the top cover.
c.
Simplify the server to the minimum configuration.
1.
The minimum configuration consists of the following:
• One cell
• Two processors
• One quad of memory DIMMS (size 256 MB or larger)
• One MP/SCSI card
• One LAN/SCSI card
• System backplane
• PCI-X backplane
• One BPS
• Two PCI power modules
• Two power cords
7.
Remove all third-party options and reinstall them one at a time, checking the server after each installation.
8.
Replace the top cover and reconnect the cables. Boot the server.
If the server does not function properly, see
“The Server Does Not Power On” (page 67) .

A yellow LED indicates that the line cord connections are not consistent with the pwrgrd settings.
2.
Verify that the power supply and both power cords are plugged in to the chassis.
The Server Powers On Then Shuts Off With a Fault Light
Use this checklist to check for the following problems when the server powers on and then off:
1.
Ensure that a conductive item has not been dropped or left inside the server chassis.
2.
Check the connections on all boards.
3.
Check the system backplane for bent pins.
Use the ps command at the Command Menu to display detailed power and hardware status for selected system hardware.
Cell Board Extraction Levers
It is important that both extraction levers on the cell board be in the locked position. Both levers must be locked in order for the MP to recognize that the cell board is powered on and functioning properly.
Power to the cell board should only be removed using the MP:CM> PE command or by shutting down the partition or server. Therefore, if the levers become unlocked, the partition will not have a chance to logically shut down, and damage could occur to the operating system.
If the cell board is powered on and one lever becomes unlocked, the cell board stays powered on. However, if the cell board is powered off, it does not power on until the cell board is extracted, reinserted, and both levers are in the locked position.
The lever status can be determined by issuing the MP:CM> DE command and viewing the power status of the cell board controller (PDHC). The “ready” bit is true only when both levers are locked and all VRMs are installed. Use this status to determine if both levers are locked, and the cell board is properly installed in the chassis. For a sample of the output, see
state is RDY (all caps), it means that the “ready bit” is true. If the state is rdy (lower case) it means that the “ready bit” is false. The meaning of each of these states is listed below.

Server Management Subsystem Hardware Overview
Server management for the HP 9000 rp7420 server is provided by an MP on the core I/O board.
The server management hardware is powered by standby power that is available whenever the server is plugged into primary AC power. This enables service access even if the DC power to the server is switched off.
The MP communicates with the server subsystems, sensors, and PDC by internal buses. It also communicates with the operating console and session gettys by universal asynchronous receiver-transmitters (UARTs) on the core I/O PCI bus.
Connection to the management processor is by way of two I/O paths:
• An RS-232 port for a local terminal
• An RS-232 port for a modem connection
• A 10/100/1000 baseT LAN port (Web console)
When the server is configured with one core I/O board, that board must be in slot 0, since the primary MP is always the MP on the core I/O board in slot 0.
When the server is configured for two partitions, it must contain two core I/O boards, one for each partition. It also contains two MPs. In this case, the MP in slot 0 is the primary MP and provides all of the server management functions. The MP on the core I/O board in slot 1 is a secondary MP and redirects the operating system gettys to the primary MP over an internal
MP-to-MP link. All external connections to the MP must be to the primary MP in slot 0. The secondary MP ports are disabled.
For high availability (HA), the server powers on and powers off without an MP. Booting HP-UX without an MP depends on the ability of the operating system to boot without a console getty.
Thus, in a two-partition system, the partition with a failed MP might not boot, since the MP provides the console getty.
The server configuration cannot be changed without the MP.
78 Troubleshooting
Resetting the MP through a modem connection can cause Admin^M to display on every Enter keystroke. Attempting a modem reset (MP command MR) does not clear this incorrect response.
This is not experienced with a telnet connection.
To regain control with a new Login prompt, follow these steps:
1.
Enter Admin (case sensitive) and press < enter > < ctrl + enter > keys.
2.
A new Login prompt is created.
3.
To move on to the Password prompt, re-enter Admin < ctrl + enter >.
4.
To reach the Main Menu, enter Admin < ctrl + enter >.
This fixes the ^M problem. The issue returns if the MP is reset through the modem.
Server Management Overview
Server management consists of four basic functional groups:
• Chassis management
• Chassis logging
• Console and session redirection
• Service access
Chassis Management
Chassis management consists of control and sensing the state of the server subsystems:
• Control and sensing of bulk power
• Control and sensing of DC-to-DC converters
• Control and sensing of fans
• Control of the front panel LEDs
• Sensing temperature
• Sensing of the power switch
• Sensing chassis intrusion
• Reading FRU PROMS
Chassis Logging
Chassis logging consists of maintaining logs of chassis codes:
• Boot codes
• Activity codes
• Error codes
Console and Session Redirection
Console and session redirection enables the console and session terminals to be connected over the RS-232 port, a modem, or a LAN connection (web console).
Service Access
Service access enables access to and control of the server state. Service access is secured by a password. Service access functions include the following:
• Access to chassis logs
• Configuration of partitions
• Control for online addition and replacement
• Access to the virtual front panel
• Transfer of control and reset
Server Management Overview 79
Server Management Behavior
This section describes how the system responds to over-temperature situations, how the firmware controls and monitors fans, and how it controls power to the server.
Thermal Monitoring
The manageability firmware is responsible for monitoring the ambient temperature in the server and taking appropriate action if this temperature becomes too high. To this end, the ambient temperature of the server is broken into four ranges: normal, overtemp low (OTL), overtemp medium (OTM), and overtemp high (OTH).
shows the actions taken at each range transition. Actions for increasing temperatures are shown on the left; actions for decreasing temps are shown on the right.
Figure 5-11 Temperature States
On large temperature swings, the server transitions through all states in order. It might go to the following state immediately, but each of the preceding actions occur. If the temperature reaches the highest range, the server be shuts down immediately by the manageability firmware.
Fan Control
There are three sets of fans in the system: those on the I/O bay, the front and rear fans that are connected to the main backplane, and those on the cell boards. The front fans run on standby power, and run any time AC input power is supplied to the server. All of the fans turn on when
48 V power is supplied to the system.
As shown in
, the fan behavior is related to the temperature state. The fans go to high speed when the ambient temperature is anywhere above the normal operating range. The front and rear fans go to high speed any time a chassis intrusion switch is triggered when removing a side cover.
Altimeter Circuit
The PCI-X backplane contains an altimeter circuit. This circuit is used to adjust the chassis fan speeds for the operating altitude at power on and during MP initialization. The chassis fans consist of the nine front fans, twelve rear fans, and the six PCI-X I/O assembly fans. If an altimeter failure is detected, the information is logged as an Event ID then propagated to the OS level to be picked up by monitoring diagnostics.
The altimeter circuit is checked at power on by the MP. If an expected value is returned from the altimeter circuit, the altimeter is determined good. The altimeter reading is then set in non-volatile random access memory (NVRAM) on board the core I/O card. If the value is ever lost like for a core I/O replacement, the NVRAM will be updated at next boot provided the altimeter is functioning normally. If the altimeter has failed, and the stable storage value has been lost because of a core I/O failure or replacement, the MP will adjust the fan speeds for sea-level operation.
80 Troubleshooting
NOTE: Fans driven to a high RPM in dense air cannot maintain expected RPM and will be considered bad by the MP leading to a “False Fan Failure” condition.
Power Control
If active, the manageability firmware is responsible for monitoring the power switch on the front panel. Setting this switch to the ON position is a signal to the MP to turn on 48 V DC power to the server. The PE command can also be used to send this signal. This signal does not always generate a transition to the powered state. The following conditions prevent the manageability firmware from applying 48 V DC power to the server:
• Insufficient number of active bulk power supplies
• Insufficient number of I/O fans
• Insufficient number of main fans
• Ambient temperature is in an OVERTEMP HIGH condition
Unless one of the following conditions occurs, 48 V DC power to the server is maintained:
• A main fan failure causes there to be an insufficient number of main fans.
• A I/O fan failure causes there to be an insufficient number of I/O fans.
• Ambient temperature reaches an OVERTEMP HIGH condition.
• The front panel power switch is turned OFF.
• The PE command is issued to the manageability firmware to turn off power to the server cabinet.

6 Removing and Replacing Server Components
This chapter describes how to shut down nPartitions, power off the server, and remove and replace hardware components in the server.
HP 9000 rp7420 Server Customer Replaceable Units
These procedures are intended for use by trained and experienced service personnel only.
Hot-Pluggable CRUs
A Customer Replaceable Unit is hot-pluggable if it can be removed from the chassis while the system remains operational, but requires software intervention before removing the CRU.
The following hardware components are hot-pluggable CRUs:
• Disk Drive
• PCI/PCI-X Card
Hot-Swappable CRUs
A CRU is hot-swappable if it can be removed from the chassis while the server remains operational and requires no software intervention before removing the CRU.
The following list identifies the hot-swappable CRUs in the HP 9000 rp7420 server.
• Front Smart Fan Assembly
• Rear Smart Fan Assembly
• PCI-X Fan Assembly
• BPS
Other CRUs
To remove and replace the CRUs that are neither hot-pluggable, nor hot-swappable, you must shut HP-UX off in the nPartition where the CRU resides, and you must power the CRU off before removing it. For detailed instructions, see
“Powering Off Hardware Components and Powering
.
These CRUs include:
• CD/DVD/DAT Drive
• PCA Front Panel Board
• PCI Power Module
Safety and Environmental Considerations
WARNING!
Before proceeding with any installation, maintenance, or service on a system that requires physical contact with electrical or electronic components, be sure that either power is removed or safety precautions are followed to protect against electric shock and equipment damage. Observe all WARNING and CAUTION labels on equipment. All installation and service work must be done by qualified personnel.
Communications Interference
HP system compliance tests are conducted with HP supported peripheral devices and shielded cables, such as those received with the system. The system meets interference requirements of all countries in which it is sold. These requirements provide reasonable protection against interference with radio and television communications.
HP 9000 rp7420 Server Customer Replaceable Units 83
Installing and using the system in strict accordance with HP's instructions minimizes the chances that the system will cause radio or television interference. However, HP does not guarantee that the system will not interfere with radio and television reception.
Take these precautions:
• Use only shielded cables.
• Install and route the cables according to the instructions provided.
• Ensure that all cable connector screws are firmly tightened.
• Use only HP supported peripheral devices.
• Ensure that all panels and cover plates are in place and secure before system operation.
Electrostatic Discharge
HP systems and peripherals contain assemblies and components that are sensitive to ESD. To prevent component damage from static electricity, carefully observe the precautions and recommended procedures in this manual.
CAUTION: Connect to ground with a wrist strap. Connection can be made to any grounded metal assembly in the cabinet. Both you and the electronic devices must be grounded to avoid static discharges that can cause damage.
To prevent component damage from static electricity, take these precautions:
• Prepare an ESD-safe work surface large enough to accommodate the various assemblies handled during the upgrade. Use a grounding mat and an anti-static wrist strap, such as those included in the ESD Field Service Kit, Part number A3024-80004.
• The anti-static bag cannot function as a static dissipating mat. Do not use the anti-static bag for any other purpose than to enclose a product.
• Treat all assemblies, components, and interface connections as static sensitive.
• When unpacking cards, interfaces, and other accessories that are packaged separately from the system, keep the accessories in the conductive plastic bags until they are ready to be installed.
• Avoid working in carpeted areas, and keep body movement to a minimum while installing accessories.
Powering Off Hardware Components and Powering On the Server
When you remove and replace hardware, you may need to power off hardware components as part of the remove and replace procedure.
This section gives details on how to power hardware components off and on.
Powering Off Hardware Components
To power off individual components or the entire cabinet, follow these steps:
1.
Log in to the MP of the server.
2.
If the component you will power off is assigned to an nPartition, then use the Virtual Front
Panel (VFP) to view the current boot state of the nPartition.
You must shut down HP-UX on the nPartition before you power off any of the hardware assigned to the nPartition.
When you are certain the nPartition is not running HP-UX, you can power off components that belong to the nPartition.
84 Removing and Replacing Server Components
NOTE: Partition configuration information is available on the HP website at http:// docs.hp.com
. For more detail, see the HP Systems Partition Guide: Administration for nPartitions.
3.
Access the MP Command menu.
From the MP Main menu, enter CM to access the Command menu.
4.
To check details about the hardware component you plan to power off, use the MP Command menu PS command.
The PS command enables you to check the status of the cabinet, system backplane, MP core
I/O, PCI power domains—or bricks—in the I/O card cage, and cells.
5.
Use the MP Command menu PE command to power off the hardware component.
You can power on or off the cabinet (including all cells and I/O in the cabinet) using the PE command, as well as individual cells along with their associated I/O domain, or PCI power domains (bricks).
Using the Command menu PE command to manage cabinet power is equivalent to using the front panel power switch.
6.
If you need to disable all power in the entire cabinet, you also must disconnect all power cords to disable all housekeeping power.
IMPORTANT: Because of power redundancy capabilities, it is important that each power cord plug into its proper receptacle. Label all power cords to indicate which receptacle each cord plugs in to. Ensure that the cabinet power is powered off before disconnecting any power cords.
7.
Perform the hardware removal and replacement procedure for the powered off component.
Powering On the Server
To power on the system after a repair, follow these steps:
1.
If needed, reconnect all power cords to the appropriate receptacles and power on the system.
2.
To power on the hardware component that was powered off and replaced, use the MP
Command menu PE command.
3.
To verify that power is enabled to the newly replaced part, use the PS command.
For example; enter C from within the PS command to select cell.
To power on the entire cabinet if power is absent from the part, enter the PE command and select T.
NOTE: You may need to allow time for some components to complete power on self test
(POST) before a complete status is available.
4.
Reboot each nPartition. See Appendix D “Operating System Boot and Shutdown”.
NOTE: Partition configuration information is available on the HP website at http:// docs.hp.com
. For more detail, see the HP Systems Partition Guide: Administration for nPartitions.
5.
Verify system functionality by using the Online Diagnostic Support Tools Manager (STM) exerciser.

Removing and Replacing a PCI Card
The PCI cards are located in the rear of the chassis in the PCI card cage. PCI cards are hot-plug components. For a list and description of hot-pluggable CRUs, see
Removing and Replacing a PCI Card 101
IMPORTANT: Complete information regarding OL* for I/O cards is on the HP website at http://docs.hp.com
. Refer to the Interface Card OL* Support Guide for details. It is strongly recommended that you obtain a copy of this guide and refer to it before beginning the removal and replacement of PCI cards.
Figure 6-21 PCI Card Location
Removing the PCI Card
This procedure describes how to perform an online replacement of a PCI card using the attention button for cards whose drivers support online add or replacement (OLAR). The attention button is also referred to as the doorbell.
NOTE: HP 9000 rp7420 servers implement manual retention latch (MRL) hardware for use in online add or replacement (OLAR) operations. If an MRL is left open while the server is booting,
HP-UX can incorrectly cache PCI slot power status causing OLAR operations to fail. To prevent this situation, ensure all the MRLs are closed before booting the server.
If OLAR reports that a slot is present and powered off, but no OLAR operations to turn power on to that slot have succeeded even after the MRL is closed, the MRL may have been left open during boot. To clear this condition, close the MRL for the PCI slot then power off the PCI slot using the rad -o command. This enables future OLAR operations to succeed on this PCI slot.
Prerequisites for this procedure are as follows:
• The card being replaced uses the same drivers and is the same type as the card being replaced.
• The green power LED is steady On.
• The yellow attention LED if steady Off or is blinking if a user has requested the slot location.
• To determine the status of all the PCI I/O slots, run the olrad -q command.
CAUTION: Observe all ESD safety precautions before attempting this procedure. Failure to follow ESD safety precautions can result in damage to the server.
To remove a PCI card, follow these steps:
1.
Remove the top cover. See
“Removing the Top Cover” (page 86) .
102 Removing and Replacing Server Components
2.
Press the attention button. See
.
The green power LED will start to blink and then turn steady Off. If the green power LED does not go Off, then check the hotplugd daemon log file (default: /var/adm/ hotplugd.log
) for errors, and do not proceed further.
NOTE: If the attention button is pressed a second time during the first five seconds while the green LED is blinking, the operation is cancelled and the power to the slot remains on.
Figure 6-22 PCI I/O Slot Details
3.
Label and remove the cables connected to the PCI card to be removed.
4.
Flip the PCI MRL for the card slot to the open position.
5.
Firmly pull up on the tabs on the PCI card separator.
6.
Remove the card from the PCI slot.
Replacing the PCI Card
To replace a PCI card, follow these steps:
1.
Install the new replacement PCI card in the slot.
NOTE: Online addition using the attention button does not perform the pre-add sequence of olrad which uses the olrad -a command.
2.
Flip the PCI MRL for the card slot to the closed position.
3.
Press the attention button. The green power LED starts to blink.
4.
Wait for the green power LED to stop blinking and turn solid green.
5.
Check for errors in the hotplugd daemon log file (default: /var/adm/hotplugd.log).
6.
Connect all cables to the replacement PCI card.
7.
Replace the top cover. See
“Replacing the Top Cover” (page 87) .
The critical resource analysis (CRA) performed while doing an attention button initiated replace action is very restrictive and the action will not complete—it will fail—to protect critical resources from being impacted.
Removing and Replacing a PCI Card 103
For finer control over CRA actions, use pdweb or the olrad command. See the Interface Card
OL* Support Guide located on the HP website at http://docs.hp.com
for details.

110 System Specifications
NOTE:
1.
“Maximum theoretical power” is used to describe input power at the AC input. It is expressed in Watts and Volt-Amps to take into account power factor correction. The calculated sum is the maximum worst case power consumption for every subsystem in the server. This number will not be exceeded by a properly functioning server for any combination of hardware and software.
2.
“Marked electrical power” is the input power measured at the AC input expressed in
Volt-Amps. The marked electrical power is the rating given on the chassis label and represents the input power required for facility AC power planning and wiring requirements. This number represents the expected maximum power consumption for the server based on the power rating of the bulk power supplies. This number can safely be used to size AC circuits and breakers for the system.
3.
“Typical maximum power” is the input power measured at the AC input expressed in Watts and Volt-Amps, and the measured maximum worst case power consumption. This number represents the largest power consumption for the server under laboratory conditions, using aggressive software applications designed specifically to work the system at maximum loads and power consumption.
DC-Powered Systems
DC-powered systems must be powered by a -48 VDC Telco power source. Follow your site-specific procedures for connecting the power and return lines to the server.
Environmental Specifications
This section provides the environmental, power dissipation, noise emission, and airflow specifications for HP Integrity rx7620 servers.
Temperature and Humidity
The cabinet is actively cooled using forced convection in a Class C1-modified environment.
Operating Environment
The system is designed to run continuously and meet reliability goals in an ambient temperature of 5° to 35° C at sea level. The maximum allowable temperature is derated 1° C per 1000 feet of elevation above 5000 feet above sea level up to 30° C at 10,000 feet. For optimum reliability and performance, the recommended operating range is 20° to 25° C
Environmental Temperature Sensor
To ensure that the system is operating within the published limits, the ambient operating temperature is measured using a sensor placed near the chassis inlet, between the cell boards.
Data from the sensor is used to control the fan speed and to initiate system overtemp shutdown.
(For more details see the platform management section.)
Non-Operating Environment
The system is designed to withstand ambient temperatures between -40° to 70° C under non-operating conditions.
Cooling
Cell Section Cooling
The cabinet incorporates front to back airflow across the cell boards and system backplane. Two
150 mm fans, mounted externally on the front chassis wall behind the cosmetic front bezel, push air into the cell section; and two 150 mm fans housed in cosmetic plastic fan carriers and mounted externally to the rear chassis wall, pull air through the cell section.
Environmental Specifications 111
Each cell area fan cooling is controlled by a smart fan control board, embedded in the fan module plastic housing. The smart fan control board receives fan control input from the system fan controller on the system backplane and returns fan status information to the system fan controller.
The smart fan control board also controls the power and the pulse width modulated control signal to the fan and monitors the speed indicator back from the fan. The fan status LED is driven by the smart fan control board.
Bulk Power Supply Cooling
Cooling for the bulk power supplies is provided by two 60 mm fans contained within each BPS.
Air flows into the front of the BPS and is exhausted out of the top of the power supply through upward facing vents near the rear of the supply. The air is then ducted out of the rear of the chassis with minimal leakage into the cell airflow plenum.
PCI/Mass Storage Section Cooling
Six 92 mm fans located between the mass storage devices and the PCI card cage provide airflow through these devices. The PCI fans are powered with housekeeping power and run at full speed at all times. The air is pulled through the mass storage devices and pushed through the PCI Card
Cage. Perforation is provided between the PCI bulkheads to allow adequate exhaust ventilation and to help reduce the localized airflow dead spots that typically occur at the faceplate tail of each PCI card.
Standby Cooling
Several components within the chassis consume significant amounts of power while the system is in standby mode. The system fans run at 1541 rpm, or 38% of full speed, during standby to remove the resulting heat from the cabinet. The fans within the power supply operate at full speed during standby.

NOTE: When determining power requirements, consider any peripheral equipment that will be installed during initial installation or as a later update. See the applicable documentation for such devices to determine the power and air conditioning that is required to support these devices.
Maximum power is the sum of the worst case power consumption of every subsystem in the box and should be used to size worst case power consumption. Typical power consumption numbers are what HP engineers have measured when running power-intensive applications. These are generally lower than maximum power numbers, because it is uncommon for all of the subsystems in the box to draw maximum power for long periods of time.

D Site Preparation Guidelines
This appendix contains blank floor plan grids and equipment templates. Combine the necessary number of floor plan grid sheets to create a scaled version of the computer room floor plan.
Figure D-1 illustrates the overall dimensions required for an HP 9000 rp7420 server.
Figure D-1 Space Requirements
Equipment Footprint Templates
Equipment footprint templates are drawn to the same scale as the floor plan grid (1/4 inch = 1 foot). These templates show basic equipment dimensions and space requirements for servicing.
The service areas shown on the template drawings are lightly shaded.
The equipment templates should be used with the floor plan grid to define the location of the equipment that will be installed in your computer room.
NOTE: Photocopying typically changes the scale of drawings copied. If any templates are copied, then all templates and floor plan grids must also be copied.
Computer Room Layout Plan
Use the following procedure to create a computer room layout plan:
1.
Remove several copies of the floor plan grid.
2.
Cut and join them together (as necessary) to create a scale model floor plan of your computer room.
3.
Remove a copy of each applicable equipment footprint template.
4.
Cut out each template selected in step 3; then place it on the floor plan grid created in step
2.
5.
Position pieces until the desired layout is obtained; then fasten the pieces to the grid. Mark locations of computer room doors, air-conditioning floor vents, utility outlets, and so on.
Equipment Footprint Templates 117
NOTE: Attach a reduced copy of the completed floor plan to the site survey. HP installation specialists use this floor plan during equipment installation.
