Server Board Features
Server Board Features
At the heart of the system is a dual-processor serverboard based on the Intel C602 chipset and
designed to provide maximum performance. The main features of the serverboard are described
in the following subsections.
Processors
The serverboard supports two four, six or eight-core, Intel Xeon E5-2600 series processors. Each
processor sits in an LGA 2011 socket and is interconnected via Intel QuickPath Interconnect (QPI)
link support; see the next subsection for more information on the QPI interconnects.
QPI Interconnect
Separate QPI link pairs connect the two processors and the I/O hub in a network on the
motherboard, allowing all of the components to access other components via the network.
Each QPI comprises two 20-lane point-to-point data links, one in each direction (full duplex), with
a separate clock pair in each direction, for a total of 42 signals. Each signal is a differential pair,
so the total number of pins is 84. The 20 data lanes are divided onto four “quadrants” of 5 lanes
each. The basic unit of transfer is the 80-bit “flit”, which is transferred in two clock cycles (four
20 bit transfers, two per clock.) The 80-bit “flit” has 8 bits for error detection, 8 bits for “link-layer
header” and 64 bits for “data”. QPI bandwidths are advertised by computing the transfer of 64 bits
(8 bytes) of data every two clock cycles in each direction
Memory
The serverboard has eight DIMM slots (four per processor) that support DDR3
1600/1333/1066/800 MHz RDIMMs. Note that memory speed support is dependent on the type
of CPU used on the mother board. Up to 256 GBs of total memory is supported.
Serial ATA and Optional SAS
A Serial ATA controller ASIC is integrated into the system serverboard to provide a standard
four-port SATA disk subsystem. Drive ports 0 and 1 are SATA 3.0 ports and the remaining drive
slots are SATA 2.0 ports. The hot-swappable SATA drives are connected to a backplane that
provides power, bus termination and configuration settings. Optional RAID 0, 1, 5, 6 and 10 are
supported. Note that your operating system must have RAID support enabled to accommodate hot
007-5839-001

1: Introduction
swapping of disk drives. Certain RAID configurations require use of optional hardware. Check
with your sales or service representative to obtain information on set-up procedures if your system
did not come pre-configured with SATA or SAS RAID.
PCI Express Expansion Slots
The dual processor serverboard has three PCIe 3.0 x16 slots to support internal double-width GPU
cards. An additional slot at the rear of the server supports one PCIe 3.0 x8 low-profile card.
See the section “PCIe Expansion Cards” in Chapter 5 for more information on these topics.
Onboard Controllers/Ports
The color-coded I/O ports include (an internal COM header located on the serverboard), VGA
(monitor) port, two external USB 2.0 ports and two gigabit LAN Ethernet ports. A dedicated
external IPMI LAN port is also included.
Onboard Graphics Controller
The dual-processor serverboard features an integrated Matrox G200 video controller providing a
16MB DDR2 graphics interface through the system VGA connector. The Matrox video controller
in the 1U server features low power consumption, high reliability and superior longevity.
IPMI
IPMI (Intelligent Platform Management Interface) is a hardware-level interface specification that
provides remote access, monitoring and administration for your SGI Rackable C1104G-RP5
server platforms. IPMI allows server administrators to view a server’s hardware status remotely,
receive an alarm automatically if a failure occurs, and power cycle a system that is non-responsive.
Other Features
Other onboard features that promote system health include onboard voltage monitors, a chassis
intrusion header, auto-switching voltage regulators, chassis and CPU overheat sensors, virus
protection and BIOS rescue.

007-5839-001
Server Chassis Features
Server Chassis Features
The following subsections provide a general outline of the main features of the SGI Rackable
C1104G-RP5 server chassis.
System Power
The Rackable C1104G-RP5 1U server chassis features a redundant power supply composed of
two separate power modules. This power redundancy feature allows you to replace a failed power
supply without shutting down the system. Note that each power supply provides up to 1800 Watts
of power to the system.
Serial ATA Subsystems
The server chassis supports up to four 2.5-in SATA drives. Drives 0 and 1 are SATA 3.0
6-Gb/second slots, drives 2 and 3 are 3-Gb/second (SATA 2.0) disk drives. RAID drives are
hot-swappable units and are connected to a backplane that provides power and control. Note that
the operating system you have installed must support RAID to enable the hot-swap capability of
RAID drives. Certain RAID levels require use of optional hardware to support RAIDed hard disk
drives in the server.
Front Control Panel
The control panel on the C1104G-RP5 server provides you with system monitoring and control.
LEDs that indicate system power, HDD activity, network activity, system overheat and a system
overheat/fan-fail/ UID LED. A main power button and a system reset button are also included.
Serverboard and GPU Subsystem
The C1104G-RP5 server chassis is an ATX form factor chassis designed to be used in a 1U
rackmount configuration. The serverboard’s I/O backplane supports up to three standard size
(double-width) GPUs to enable high-quality GPU computing solutions. A 15-pin VGA port, two
USB 2.0 ports, two Gigabit LAN ports and a dedicated RJ-45 IPMI LAN port are also supported.
The GPUs process complex image calculations and then route the data out through the VGA port
on the serverboard. The GPUs, which come with a passive heatsink attached, have been tested for
use with this system.
007-5839-001
5
1: Introduction
Important: Check with your SGI sales or service representative prior to using any GPU not
sourced at the SGI factory.
Any combination of these cards (up to a total of three) may have come bundled with the system.
Power for the GPU cards is provided via a GPU power cable from each of the GPUs to JPW3, 4,
6 and 7 on the serverboard (one cable for each card). Figure 1-2 on page 7 shows a general block
diagram of the C1104G-RP5 server’s processor and I/O chipset.
GPU Features
Each of the GPUs will feature some or all of the following:
•
Hundreds of GPU cores in each card that can deliver more than 660 Gigaflops of
double-precision and over one Teraflop of single-precision calculations.
•
ECC protected internal register files, L1/L2 caches, shared memory, and external DRAM.
•
Up to 6 GB of GDDR5 memory per GPU enhances performance and reduces data transfers
by keeping larger data sets in local memory attached directly to the GPU.
•
Integrates the GPU subsystem with the C1104G-RP5 server’s monitoring and management
capabilities such as IPMI.
•
Onboard L1 and L2 caches that accelerate algorithms and sparse-matrix multiplication.
•
Provides faster context switching, concurrent kernel execution and improved thread block
scheduling.
•
Enhances overall system performance by transferring data over the PCIe bus while the
computing cores are processing other data.
•
Provides a flexible programming environment with broad support for various programming
languages and APIs.
Cooling System
The 1U server chassis has a cooling design that includes ten internal 4-cm counter-rotating Pulse
Width Modulated (PWM) system cooling fans located in the chassis. An air shroud channels the
airflow from the system fans to efficiently cool the processor and GPU areas of the system. Each
power supply module also includes an internal cooling fan. All chassis and power supply fans
operate continuously.

2. Server Installation
This chapter provides a quick setup checklist to get the SGI Rackable C1104G-RP5 operational.
If your system came already mounted in a rack, you can skip the rack installation procedures.
Unpack the System
Inspect the shipping container that the C1104G-RP5 was shipped in and note if it was damaged in
any way. If the server shows damage, file a damage claim with the carrier who delivered it.
Decide on a suitable location for the rack that supports the weight, power requirements, and
environmental requirements of the C1104G-RP5 server. It should be situated in a clean, dust-free
environment that is well ventilated. Avoid areas where heat, electrical noise, and electromagnetic
fields are generated. Place the server rack near a grounded power outlet. Refer also to “System
Warnings and Precautions” on page 10.
Prepare for Setup
The shipping container should include two sets of rail assemblies, two rail mounting brackets and
the mounting screws that you will use to install the system into a rack. Note that the inner rails
should already be attached to the server. Read this section in its entirety before you begin the
installation procedure.
Choose a Setup Location
Leave enough clearance in front of the rack to enable you to open the front door completely (~25
inches) and approximately 30 inches of clearance in the back of the rack to allow for sufficient
airflow and ease in servicing. This clearance may vary depending on the type of rack and
installation site chosen. This product is for installation only in an (IEC 60950) Restricted Access
Location - dedicated equipment rooms, service closets and labs, etc. See also, “Regulatory
Compliance” in Appendix B.

Rack Mounting Considerations
Server Precautions
•
Review the electrical and general safety precautions.
•
Determine the placement of each component in the rack before you install the rails.
•
Install the heaviest server components in the bottom of the rack first, and then work up.
•
Add a regulating uninterruptible power supply (UPS) to protect the server from power
surges and voltage spikes and to keep your system operating in case of a power failure.
•
Allow the hot-pluggable disk drives and power supply modules to cool before touching.
•
Always keep the rack’s front door and all panels and components on the servers closed when
not servicing to maintain proper cooling.
•
The server is not considered suitable for visual display work place devices under the German
government ordinance for work with visual display units.
Rack Mounting Considerations
Use the guidelines provided in the following subsections to properly install the server in a rack.
Ambient Operating Temperature
If installed in a closed or multi-unit rack assembly, the ambient operating temperature of the rack
environment may be greater than the ambient temperature of the room. Therefore, consideration
should be given to installing the equipment in an environment compatible with the manufacturer’s
maximum rated ambient temperature (35º C or 95º F).
Important: In a system using three NVIDIA M2090 GPUs the maximum rated ambient
temperature of the operational environment should be 30º C (86º F). A system using two M2090
GPUs in the front slot positions can be operated at 35º C (95º F) with 115 watt system CPUs.
Check with your SGI sales or service representative for additional information on this topic.
Reduced Airflow
Equipment should be mounted into a rack so that the amount of airflow required for safe operation
is not compromised.
007-5839-001
11
2: Server Installation
Mechanical Loading
Equipment should be mounted into a rack so that a hazardous condition does not arise due to
uneven mechanical loading. Racks should generally be filled with equipment from the bottom up.
Circuit Overloading
Consideration should be given to the connection of the equipment to the power supply circuitry
and the effect that any possible overloading of circuits might have on overcurrent protection and
power supply wiring. Appropriate consideration of equipment nameplate ratings should be used
when addressing this concern.
Reliable Ground
A reliable ground must be maintained at all times. To ensure this, the rack itself should be
grounded. Particular attention should be given to power supply connections other than the direct
connections to the branch circuit (for example, the use of power strips, and so on).
Install the System into a Rack
This section provides information on installing the C1104G-RP5 into a rack. If the system has
already been mounted into a rack, refer to “Supply Power to the System” on page 19. There are a
variety of rack units on the market, which may mean the assembly procedure will differ slightly.
You should also refer to the installation instructions that came with the rack unit you are using.
Note that this system’s rail kit is designed to fit a rack between 26-in and 33.5-in deep.
Separate the Sections of the Rack Rails
The chassis package includes two rail assemblies in the rack mounting kit.
Each assembly consists of two sections: an inner fixed chassis rail that secures directly to the
server chassis and an outer fixed rack rail that secures directly to the rack itself. Note that the inner
rail may be pre-installed on the server by the SGI factory making separation steps unnecessary.
To separate the inner and outer rails, perform the following steps:
12
007-5839-001
Install the System into a Rack
1.
Locate the rail assembly in the chassis packaging as shown in Figure 2-2.
2. Extend the rail assembly by pulling it outward.
3. Press the quick-release tab
4. Separate the inner rail from the outer rail assembly.

2: Server Installation
Inner Rail Extensions
The chassis includes a set of inner rack rails in two sections:
•
inner rails
•
inner rail extensions
The inner rails are preattached to the server chassis and do not interfere with normal use of the
system if you decide not to install it into a server rack. Attaching the inner rail extensions to the
inner rails stabilizes the chassis within the rack is described in the following subsection.
Installing the Inner Rail Extensions
1.
Place the inner rail extensions over the preattached inner rails which are attached to the side
of the chassis. Align the hooks of the inner rail with the rail extension holes. Make sure the
extension faces “outward” just like the inner rail.
2. Slide the extension toward the front of the chassis.
3. Secure the chassis with screws as illustrated in Figure 2-3 on page 15.
4. Repeat steps 1-3 for the other inner rail extension.

Rail to Server Chassis Attachment Example
Assembling the Outer Rails
Each outer rail is in two sections that must be assembled before mounting on to the rack.
Assembling the Outer Rails
1.
Identify the left and right outer rails by examining the ends, which bend outward.
2. Slide the front section of the outer rail into the rear section of the outer rail.
3. The assembly should look similar to the example in Figure 2-4 on page 16.
007-5839-001

Figure 2-4
Outer Rail Assembly Example
Attaching the Outer Rack Rails
Outer rails attach to the rack and hold the chassis in place. They extend between 26.5 and 36.4
inches.
1.
Measure the depth of the rack (distance from the front rail to the rear rail) to ensure it
complies with the limitations listed.
2. Adjust the outer rails to the proper length to fit within the rack. See the placement example in
Figure 2-5 on page 17.
3. Hang the hooks of the front of the outer rail onto the slots on the front of the rack. Use
screws to secure the outer rails to the rack.
4. Pull out and adjust both the short and long brackets to the proper distance so that the rail can
fit snugly into the rack, reference Figure 2-6 on page 18.
5. Hang the hooks of rear portion of the outer rail into the slots on the rear of the rack. Secure
the long bracket to the rear side of the outer rail with the screws provided.
6. Repeat the previous steps to properly install the left outer rail.

Outer Rack Rail Assembly/Placement Example
Using the Rail Locking Tabs
Both chassis rails have a locking tab, which serves two functions:
007-5839-001
•
The tabs can lock the server into place when installed and pushed fully into the rack, (its
normal operating position).
•
The tabs also lock the server in place when fully extended from the rack. This prevents the
server from coming completely out of the rack when pulled out for servicing. Depress both
tabs at the same time to fully remove the server from its rail mounting and extract it from the
rack.

3. Slide the inner rails into the outer rails, keeping the pressure even on both sides. When the
chassis has been pushed completely into the rack, it should click into the locked position.
4. Optional screws are recommended to secure and hold the front of the chassis to the rack.
Supply Power to the System
Connect the power cords from the power supply modules into a power strip or power distribution
unit (PDU) within the rack. An optionally available uninterruptible power supply (UPS) can
ensure continued operation in case of a failure of the regular power source.
After all power connections are verified, push the power-on button on the front of the server when
you wish to power on the unit.

Power Fail LED
Overheat/Fan Fail/UID LED
When the red overheat/fan/UID LED flashes (shown in Figure 3-5), it indicates a fan failure.
When on continuously it indicates an overheat condition, which may be caused by cables
obstructing the airflow in the system or the ambient room temperature being too warm.
Check the routing of the cables and make sure all fans are present and operating normally. You
should also check to make sure that the chassis covers and fan shrouds are installed properly. This
LED will remain flashing or on as long as the indicated condition exists.
The “blue light” function (UID) of this LED is used to identify a specific server in large racks
filled with equipment. When activated through the system software the “blue light” will remain
on until shut down by the administrator.

4. System Safety
This chapter describes basic safety precautions when using the server.
Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself from harm and the
Rackable C1104G-RP5 system from damage, as follows:
007-5839-001
•
Be aware of the locations of the power on/off switch on the chassis as well as the room's
emergency power-off switch, disconnection switch or electrical outlet. If an electrical
accident occurs, you can then quickly remove power from the system.
•
Do not work alone when working with high voltage components.
•
Power should always be disconnected from the system when removing or installing main
system components, such as the memory modules and disk drives. When disconnecting
power, you should first power down the operating system and then unplug the power cords.
The unit can have more than one power supply cord. Disconnect two power supply cords
before servicing to avoid electrical shock.
•
When working around exposed electrical circuits, another person who is familiar with the
power-off controls should be nearby to switch off the power if necessary.
•
Use only one hand when working with powered-on electrical equipment. This is to avoid
making a complete circuit, which will cause electrical shock. Use extreme caution when
using metal tools, which can easily damage any electrical components or circuit boards they
come into contact with.
•
Do not use mats designed to decrease static electrical discharge as protection from electrical
shock. Instead, use rubber mats that have been specifically designed as electrical insulators.
•
The power supply power cords must include a grounding plug and must be plugged into
grounded electrical outlets or power distribution unit (PDUs).
27
4: System Safety
Serverboard Battery
Caution: There is a danger of explosion if an onboard battery is installed upside down, which
will reverse its polarities (see Figure 4-1). This battery must be replaced only with the same
or an equivalent type recommended by the manufacturer. Check with your service
representative if you have any questions.
!
Lithium battery

Figure 4-1
Installing the Onboard Battery
Important: Handle used batteries carefully and do not damage the battery in any way; a damaged
battery may release hazardous materials into the environment. Do not discard a used battery in the
garbage or a public landfill. Dispose of used batteries according to the manufacturer's instructions
and in compliance with the regulations set up by your local hazardous waste management agency.
ESD Precautions
Caution: This server contains electronic components and printed circuit boards which are
susceptible to electrostatic discharge (ESD) damage. ESD is generated by two objects with
different electrical charges coming into contact with each other. An electrical discharge is
created to neutralize this difference, which can damage electronic components and printed
circuit boards.
!
The following measures are generally sufficient to neutralize this difference before contact is
made to protect your equipment from ESD:
•
28
Use a grounded wrist strap designed to prevent static discharge.
007-5839-001
General Safety Precautions
•
Keep all components and printed circuit boards (PCBs) in their antistatic bags until ready for
use.
•
Touch a grounded metal object before removing the board from the antistatic bag.
•
Do not let components or PCBs come into contact with your clothing, which may retain a
charge even if you are wearing a wrist strap.
•
Handle a board by its edges only; do not touch its components, peripheral chips, memory
modules or contacts.
•
When handling chips or modules, avoid touching their pins.
•
Put the serverboard and peripherals back into their antistatic bags when not in use.
•
For grounding purposes, make sure your computer chassis provides excellent conductivity
between the power supply, the case, the mounting fasteners and the serverboard.
Mainboard Replaceable Soldered-in Fuses
Important: If your system comes with self-resetting PTC (Positive Temperature Coefficient)
fuses on the serverboard, they must be replaced by trained service technicians only. The new fuse
must be the same or equivalent as the one replaced. Contact your technical support organization
for details and support.
General Safety Precautions
Follow these rules to ensure general safety:
007-5839-001
•
Keep the area around the Rackable C1104G-RP5 system clean and free of clutter.
•
The Rackable C1104G-RP5 system weighs approximately 37 lbs (16.8 kg.) when fully
loaded. When lifting the system, two people at either end should lift slowly with their feet
spread out to distribute the weight. Always keep your back straight and lift with your legs.
•
Place the chassis top cover and any system components that have been removed away from
the system or on a table so that they won't accidentally be stepped on.
•
While working on the system, do not wear loose clothing such as neckties and unbuttoned
shirt sleeves, which can come into contact with electrical circuits or be pulled into a cooling
fan.
29
4: System Safety
30
•
Remove any jewelry or metal objects from your body, which are excellent metal conductors
that can create short circuits and harm you if they come into contact with printed circuit
boards or areas where power is present.
•
After accessing the inside of the system, close the system back up and secure it to the rack
unit with the retention screws after ensuring that all connections have been made.

chassis and understand the system PCIe expansion cards and hard disk drives. Use the information
in Chapter 6 to troubleshoot your server and add, remove, or replace system components.
A layout and quick reference chart is included in this chapter for your reference.
Some software products are protected with software license keys derived from the Media Access
Control (MAC) Ethernet address. If your system requires the replacement of a node board, the
MAC Ethernet address changes. If you are using such a product, you or your service representative
must request a new license key after replacement of a node board. Contact your local customer
support office:
http://www.sgi.com/support/supportcenters.html
!
Caution: Install the chassis cover after you have completed accessing the components inside the
server to maintain proper airflow and cooling for the system.
Handling Circuit Boards and Drives
!
Caution: Electrostatic discharge (ESD) can damage electrostatic-sensitive devices inside the
C1104G-RP5 server. Use the ESD precautions described below when you handle printed circuit
boards or other components in the system. The following measures are generally sufficient to
protect your equipment from electro-static discharge.
ESD Precautions
•
Use a grounded wrist strap designed to prevent electrostatic discharge.
•
Touch a grounded metal object before removing any board from its antistatic bag.
•
Handle each printed circuit board (PCB) by the edges; do not touch the components,
peripheral chips, memory modules, or gold contacts on the PCB.
•
When handling chips or modules, avoid touching the pins.
•
Store PCIe cards, or other boards and components in antistatic bags when not in use.
•
Make sure your computer chassis provides a conductive path between the power supply, the
case, the mounting fasteners, and the node board to chassis ground.
Unpacking
!
Caution: System options are shipped in antistatic packaging to avoid electrostatic discharge
damage. Be sure to use ESD precautions when you unpack upgrade or replacement components

Hard Disk Drives (C1104G-RP5 Chassis)
The 1U chassis supports a maximum of four 2.5-inch hard disk drives, see Figure 5-3. Install the
drives from left to right starting in the lower-left bay. Disk drive bays must be populated with
either a drive or a “drive blank” to maintain system thermals. Failure to follow this guideline may
cause system overheating and thermal shutdown of the unit.
Important: The operating system you use must have RAID support to enable the hot-swap
capability and RAID functions of the SATA drives.

C1104G-RP5 System Disk Drive Locations
Drive Configurations
The disk drive configurations supported in the Rackable C1104G-RP5 server are outlined in the
paragraphs that follow. Note that some configurations are dependent on use of optional hardware
to support RAID configurations.
The supported disk drive configurations are as follows:
•
JBOD
This non-RAID disk array supports any number of drives between one and four. The
operating system is placed on the disk drive in location 0 (system disk). All other drives are
data drives.
•
RAID 0
Disk striping without parity, supports any number of drives between two and four. Note that
all drives must be the same type, speed and capacity. The operating system will be striped
across all drives in the system. This configuration is not recommended.
•
RAID 1
Disk “mirroring”, supports exactly two drives. The two drives represent one RAID 1 logical
drive. The operating system will be installed on the drives located in Drive positions 0 and 1.
Note that both drives 0 and 1 must be of the same type, speed and capacity.
•
RAID 5
Disk striping with distributed parity - each RAID 5 drive has its own parity resource. A
minimum of three drives are required for a functional RAID 5 array. A single drive failure
will result in decreased performance until the damaged drive is replaced and the parity
rebuild is complete. RAID 5 is generally favored in a “read-heavy” data environment as
write operations will execute at a slower rate.
Note that all drives must be the same type, speed and capacity.
•
RAID 6
RAID 6 enhances RAID 5 style disk striping parity distribution by creating enough parity
data to handle two disk failures. You can lose a disk and have an unrecoverable error (URE)
during reconstruction and still reconstruct your system data. Calculations for the RAID 6
parity stripes are more complicated than those for RAID 5; virtually doubling the workload
for the processor on the RAID controller and exacting a performance penalty on write
operations. Up to 40% of data space on each disk must be devoted to RAID 6 parity
information. Optional hardware is required to support RAID 6 functionality.
Note that all drives must be the same type, speed and capacity.
•
RAID 10
Mirrored disk striping, the data is striped across one set of drives and then mirrored on
another set of drives. A minimum of four drives of the same type are required. The total
number of drives must be an even number (4 in this case). A total of four drives is a 2+2
configuration. The operating system will be striped across the drives in the primary set and
then mirrored on the secondary set of drives.
Note that all drives must be the same type, speed and capacity.
PCIe Expansion Cards
There are three internal double-width (GPU) PCIe 3.0 x16 expansion slots and two external PCIe
slots available with the C1104G-RP5 server. The external option slot functions as listed:
•
External PCI-Express 3.0 x8 low-profile card
PCIe Expansion Cards
Note: Only specific GPU cards will fit and function in the internal PCIe GPU slots, contact your
SGI sales or service representative for information on approved GPU cards.
Power Supply Functional Rating
The C1104G-RP5 server default configuration is two rear-installed 1800-Watt power supplies.
The second power supply acts as a redundant power unit for the server. The supplies are
“auto-ranging” and can operate from either 100-140V or 180-240V levels at 50 or 60Hz.
Each power supply module has its own cooling fan.
The supplies used have an 80 Plus Platinum Certification rating.

6. Basic Troubleshooting and Chassis Service
Use the procedures in the first half of this chapter to troubleshoot your system. If you have
followed all of the procedures below and still need assistance, check with your authorized support
organization.
The subsections in the second half of this chapter starting with “Chassis Service Information” on
page 43 are intended to guide you through basic component remove and replace procedures.
Basic Troubleshooting Procedures
Use the information in the following subsections to remedy basic problems you might encounter
when working with the Rackable C1104G-RP5 server.
If the System Does Not Power Up
If the system will not power up when the front power button is pushed, use the following checklist
to identify common sources for the problem:
•
Make sure that both ends of each system power cable are firmly connected to the power
supply and the corresponding power source(s) or power distribution unit (PDU).
•
Check to see if the power fail LED is lit on the front of the unit. This LED should be off if
the system is operating normally.
•
Check that the LED on each power supply is properly lit. The power supply has one status
LED located on the left side of the front of the power supply. The LED has three states:
•
007-5839-001
–
Dark or off - indicates no AC power present
–
Yellow - AC power is present, the server is not turned on (no DC power)
–
Green - AC power is present and the server is turned on (DC power present)
Open the system cover, remove the air shroud and check to make sure that no obvious short
circuits exist between the serverboard and chassis.
41
6: Basic Troubleshooting and Chassis Service
System Powers Up But Will Not Boot
If the system powers up but will not boot the Operating System, check the following:
•
Check the system order document(s) - the C1104G-RP5 server may have been ordered with
no operating system. If so, check with your system administrator for OS loading
information.
•
Check the system disk (drive 0) for drive activity and confirm that it is firmly seated in the
disk bay. A red light on the front of the disk indicates a functional error. Check with your
service provider or local system administrator.
No Video After System Power Up
If the system powers up and appears to be booting normally but no video is present, try the
following basic solutions:
•
Confirm your monitor is plugged in and switched on.
•
Check all video cables and ensure they are properly connected.
•
Listen for a BIOS “beep code” error message - one long beep plus 8 short beeps indicates a
video error. This beep code message could indicate a video memory error or other video
malfunction; contact your service provider.
•
If using an optional PCIe video card check the back of the card for LED activity or a fault
indicator. Try opening the system, reseating the PCIe card and rebooting; see the section
“Install/Replace a PCIe Expansion Card” on page 57.
If you cannot get a video signal after trying basic solutions contact your support provider.
Memory Errors
If your system experiences memory related errors, try these basic troubleshooting steps to resolve
or better identify the problem:
42
•
Confirm that the power supply LED is not indicating an error.
•
Listen for memory error beep codes - five short beeps followed by one long beep is a BIOS
signal that no system memory has been detected - See Appendix A, “BIOS Error Codes”.
•
Shut the system down, remove the covers over the serverboard and make sure that all the
DIMM modules are properly and fully installed.
007-5839-001
Chassis Service Information
•
You should be using registered ECC DDR3 memory. Also, it is recommended that you use
the same memory type and speed for all DIMMs in the system.
•
Contact your administrator or support provider if the memory errors continue.
Chassis Service Information
The following sections cover the steps required to install components and perform maintenance
on the C1104G-RP5 chassis. For component installation, follow the steps in the order given to
eliminate the most common problems encountered. If some steps are unnecessary, skip ahead to
the step that follows.
Important: Always disconnect the AC power cord(s) before adding, changing or installing any
internal hardware components.
Tools Required: The only tool you will need to install components and perform maintenance is
a Phillips screwdriver.
Static-Sensitive Devices
Electrostatic discharge (ESD) can damage electronic components. To prevent damage to any
printed circuit boards (PCBs), it is important to handle them very carefully. The following
measures are generally sufficient to protect your equipment from ESD damage.
Precautions
007-5839-001
•
Use a grounded wrist strap designed to prevent static discharge.
•
Touch a grounded metal object before removing any board from its antistatic bag.
•
Handle a board by its edges only; do not touch its components, peripheral chips, memory
modules or gold contacts.
•
When handling chips or modules, avoid touching their pins.
•
Put the serverboard, add-on cards and peripherals back into their antistatic bags when not in
use.
43
6: Basic Troubleshooting and Chassis Service
•
For grounding purposes, make sure your computer chassis provides excellent conductivity
between the power supply, the case, the mounting fasteners and the serverboard.
Unpacking
Replacement components are usually shipped in antistatic packaging to avoid static damage.
When unpacking an upgrade or replacement component, make sure the person handling it is static
protected.
Control Panel
The control panel (located on the front of the chassis) must be connected to the JF1 connector on
the serverboard to provide you with system status indications. A ribbon cable has bundled these
wires together to simplify the connection. Connect the cable from JF1 on the serverboard to the
Control Panel PCB (printed circuit board). Make sure the red wire plugs into pin 1 on both
connectors. Pull all excess cabling out of the airflow path. The LEDs inform you of system status.
See Chapter 3 for details on the LEDs and the control panel buttons.
Drive Bay Installation/Removal
This section describes hard drive installation and removal.
Accessing the Drive Bays
Drives: You do not need to access the inside of the chassis or remove power to replace or swap a
RAIDed hard disk drive. Data may be lost or corrupted if you “hot swap” a JBOD disk drive. Shut
down system power before removing or replacing a JBOD disk. Removing either a RAID or
JBOD drive without replacing it may cause system errors. Proceed to the next section for further
hard drive instructions.
Note: You must use approved 2.5" disk drives in the system.
44
007-5839-001
Drive Bay Installation/Removal
Removing Hard Drives or Carriers from the Chassis
1.
Press the release button on the drive carrier. This extends the drive carrier handle.
2. Use the handle to pull the drive carrier out of the chassis.
Important: Empty carriers without drives must stay in the chassis during operation for proper
airflow/cooling purposes except during remove/replace operations. Do not operate the server with
carriers removed.
The Hard Drive Backplane
The hard drives plug into a backplane that provides power, drive ID and bus termination. A RAID
controller and/or optional RAID software can be used with the backplane to provide data security.
The operating system you use must have RAID support to enable the hot-swap capability of the
hard drives. The backplane is preconfigured, so no jumper/switch configuration is required.
!
Caution: Be careful when working around the drive backplane. Do not touch the backplane with
your fingers or any metal objects and make sure no ribbon cables touch the backplane or obstruct
the holes, which aid in proper airflow.
Disk Drive Installation
The drives are mounted in drive carriers to simplify their installation and removal from the
chassis, see Figure 6-1 on page 46 for a disk drive removal example. These carriers also help
promote proper airflow for the drives. For this reason, even empty carriers without hard drives
installed must remain in the chassis during operation.
See Figure 6-2 on page 48 for an example drive carrier and the “dummy” drive blank used when
a working disk is not installed in a drive slot.
007-5839-001

2. Insert a new/replacement hard drive into the carrier with the PCB side facing down and the
connector end toward the rear of the carrier.
3. Align the hard drive in the disk drive carrier so that the mounting holes of the carrier are
aligned with the mounting holes of the drive. Note that there are holes in the carrier which
are marked “SATA” to aid in correct installation.
4. Secure the drive to the carrier with four screws. Use the M3 flat-head screws included in the
HDD bag of your accessory box. Note: the screws used to secure a dummy drive to the
carrier should not be used to secure the hard drive.
46
007-5839-001
Drive Bay Installation/Removal
5. Insert the hard drive carrier assembly into its bay vertically, keeping the carrier oriented so
that the release button is on the bottom. When the carrier reaches the rear of the drive bay,
the handle will retract.
6. Using your thumb, push against the upper part of the hard drive handle until the assembly
clicks into the locked (fully seated) position, see Figure 6-3 on page 49 for an example.
Note: Your operating system must have RAID support to enable the hot-plug capability of the
drives.
!
007-5839-001
Caution: Regardless of how many hard drives are installed, all drive carriers must remain in the
drive bays to maintain proper airflow and system cooling.

Power Supply
I
Figure 6-3
Hard Disk Drive Installation Example
Power Supply
The system offers a redundant power supply assembly consisting of two 1800-watt power
modules. Each power supply module has an auto-switching capability, which enables it to
automatically sense and operate at a 100V - 240V input voltage at 50 or 60Hz.
Power Supply Failure
If either of the two power supply modules fail, the other module will take the full load and allow
the system to continue operation without interruption. The PWR Fail LED will illuminate and
remain on until the failed unit has been replaced. The power supply units have a hot-swap
capability, meaning you can replace the failed unit without powering down the system, see
Figure 6-4 on page 51 for an example.
007-5839-001

6: Basic Troubleshooting and Chassis Service
Removing/Replacing a Power Supply
You do not need to shut down the system to replace a failed power supply unit. The backup power
supply module will keep the system up and running while you replace the failed unit. Replace with
the same model.
Removing the Power Supply
1.
First unplug the AC power cord from the failed power supply module.
2. Depress the locking tab on the power supply module.
3. Pull it straight out using the rounded handle.
Installing a New Power Supply
1.
Replace the failed hot-swap unit with another identical power supply unit.
2. Push the new power supply unit into the power bay until you hear a click.
3. Secure the locking tab on the unit.

Accessing the Inside of the Chassis
1.
Grasp the two handles on either side and pull the unit straight out until it locks (you will hear
a “click”).
2. Next, depress the two buttons on the top of the chassis to release the top cover and at the
same time, push the cover away from you until it stops. You can then lift the top cover from
the chassis to gain full access to the inside of the server.
Note: Normally you would power down the system before installing or removing internal
components - but it may be necessary to leave system power on to determine which fan has failed.
System Fans
Ten 4-cm counter-rotating fans provide the cooling for the system. Each fan unit is actually made
up of two fans joined back-to-back, which rotate in opposite directions. This counter-rotating
action generates exceptional airflow and works to dampen vibration levels. It is very important
that the chassis top cover is properly installed and making a good seal in order for the cooling air
to circulate properly through the chassis and cool the components.
System Fan Failure
Fan speed is controlled by system temperature via a BIOS setting. If a fan fails, the remaining fans
will ramp up to full speed and the overheat/fan fail LED on the control panel will flash. Replace
any failed fan as soon as possible with the same type and model (the system can continue to run
with a failed fan).
Your system administrator may be able to identify which fan has failed using the system BIOS.
If an administrator or service representative is not using the BIOS to determine which fan has
failed, you can remove the top chassis cover while the system is still running to determine which
of the fans has failed. After determining which is the failed fan, remove power from the system
by unplugging the server’s cord. Never run the server for an extended period of time with the top
cover open.

Replacing System Fans
This section describes how to remove or install a system fan.
Remove/Replace a Fan
1.
If you have not already done so, remove the chassis cover to access the fans, see the example
in Figure 6-5 on page 54.
2. Turn off the power to the system and unplug the AC power cord.
3. Remove the failed fan's wiring connectors from the serverboard.
4. Remove and retain the four pins securing the fan assembly to the fan tray.
5. Lift the assembly housing the failed fan from the fan tray and out of the chassis, see the
example in Figure 6-6 on page 55.
6. Place the new fan into the vacant space in the fan tray, while making sure the arrows on the
top of the fan (indicating air direction) point in the same direction as the arrows on the other
fans in the same fan tray. See Figure 6-7 on page 56 for a fan assembly example.
7. Reconnect the fan wires to the exact same chassis fan headers as the previous fan.
8. Reconnect the AC power cord, power up the system and check that the fan is working
properly before replacing the chassis cover.

Install/Replace a PCIe Expansion Card
Install/Replace a PCIe Expansion Card
Confirm that you have the correct PCIe card for your chassis and the card includes a standard
bracket. The following type card is supported in the server chassis:
•
One low-profile PCIe 3.0 x8 card
•
One optional full-height PCIe 3.0 x16 card (optional if only front GPU slots are populated)
Low-profile PCIe slot

x16 full-height PCIe slot
PCIe Low-profile and Optional Full-height Slot Locations
Install/Replace a Low-profile or Full-height PCIe Card
Use the following steps and illustration to install or replace a PCIe card at the rear of the system:
1.
Remove the chassis cover and disconnect both the power cables from the server.
2. Confirm that you have the correct size and type of PCIe expansion card (low-profile or
full-height depending on the slot used).
Note: If your system uses three GPU boards then the x16 full-height PCIe slot is not usable.
3. Remove the screw securing the low-profile or full-height PCIe slot cover at the rear of the
chassis and slide it sideways to remove from the chassis.
4. Select the appropriate riser connector for your low-profile card. Note that both the
low-profile and full-height riser cards use a x16 connector.
5. Align the PCIe card with the rear slot opening and the riser connector, then simultaneously
slide the rear bracket into place as you insert the PCIe connector into the riser.
6. Secure the rear bracket in the slot with the screw removed in step 3 and connect cables to the
add-on card as necessary. See Figure 6-9 on page 58 for an example.

Appendix A
A. BIOS Error Codes
During Power-On Self-Test (POST) routines, which are performed each time the system is
powered on, errors may occur.
Non-fatal errors are those which, in most cases, allow the system to continue the boot-up process.
The error messages normally appear on the screen.
Fatal errors are those which will not allow the system to continue the boot-up procedure. If a fatal
error occurs, you should consult with your system manufacturer for possible repairs.
These fatal errors are usually communicated through a series of audible beeps. The numbers on
the fatal error list (see Table A-1) correspond to the number of beeps for the corresponding error.
