Initial Server Setup
This section includes the following topics:
•
Connecting and Powering On the Server (Standalone Mode), page 2-8
•
NIC Modes and NIC Redundancy Settings, page 2-10
Connecting and Powering On the Server (Standalone Mode)
Note
The server is shipped with a default NIC mode called Shared LOM EXT, default NIC redundancy is
active-active, and DHCP is enabled. Shared LOM EXT mode enables the 1-Gb Ethernet ports and the
ports on any installed Cisco virtual interface card (VIC) to access the Cisco Integrated Management
Interface (CIMC). If you want to use the 10/100 dedicated management ports to access the CIMC, you
can connect to the server and change the NIC mode as described in Step 3 of the following procedure.
In that step, you can also change the NIC redundancy and set static IP settings.
Use the following procedure to perform initial setup of the server:
Step 1
Attach a supplied power cord to each power supply in your server, and then attach the power cord to a
grounded AC power outlet. See the Power Specifications, page A-2 for power specifications.
Wait for approximately two minutes to let the server boot in standby power during the first bootup.
You can verify power status by looking at the Power Status LED (see Figure 1-1 on page 1-2):
•
Off—There is no AC power present in the server.
•
Amber—The server is in standby power mode. Power is supplied only to the CIMC and some
motherboard functions.
•
Green—The server is in main power mode. Power is supplied to all server components.
Note
Step 2
During bootup, the server beeps once for each USB device that is attached to the server. Even if
there are no external USB devices attached, there is a short beep for each virtual USB device
such as a virtual floppy drive, CD/DVD drive, keyboard, or mouse. A beep is also emitted if a
USB device is hot-plugged or hot-unplugged during BIOS power-on self test (POST), or while
you are accessing the BIOS Setup utility or the EFI shell.
Connect a USB keyboard and VGA monitor to the server.

Chapter 2
Installing the Server
Initial Server Setup
Step 3
Set NIC mode, NIC redundancy, and choose whether to enable DHCP or set static network settings:
a.
Press the Power button to boot the server. Watch for the prompt to press F8.
b.
During bootup, press F8 when prompted to open the BIOS CIMC Configuration Utility.
c.
Set the NIC mode to your choice for which ports to use to access the CIMC for server management
(see Figure 1-3 for identification of the ports):
•
Shared LOM EXT (default)—This is shared LOM extended mode. This is the factory-default
setting, along with Active-active NIC redundancy and DHCP-enabled. With this mode, the shared
LOM and Cisco Card interfaces are both enabled.
In this mode, DHCP replies are returned to both the shared LOM ports and the Cisco card ports. If
the system determines that the Cisco card connection is not getting its IP address from a Cisco UCS
Manager system because the server is in standalone mode, further DHCP requests from the Cisco
card are disabled. Use the Cisco Card NIC mode if you want to connect to the CIMC through a Cisco
card in standalone mode.
•
Dedicated—The dedicated management port is used to access the CIMC. You must select a NIC
redundancy and IP setting.
•
Shared LOM—The 1-Gb Ethernet ports are used to access the CIMC. You must select a NIC
redundancy and IP setting.
•
Cisco Card—The ports on an installed Cisco UCS virtual interface card (VIC) are used to access the
CIMC. You must select a NIC redundancy and IP setting.
Note
d.
The Cisco Card NIC mode is currently supported only with a Cisco UCS VIC that is installed in
PCIe slot 2. See also Special Considerations for Cisco UCS Virtual Interface Cards, page 3-36.
Use this utility to change the NIC redundancy to your preference. This server has three possible NIC
redundancy settings:
– None—The Ethernet ports operate independently and do not fail over if there is a problem.
– Active-standby—If an active Ethernet port fails, traffic fails over to a standby port.
– Active-active—All Ethernet ports are utilized simultaneously.
e.
Note
f.
Note
g.
Note
Choose whether to enable DHCP for dynamic network settings, or to enter static network settings.
Before you enable DHCP, your DHCP server must be preconfigured with the range of MAC
addresses for this server. The MAC address is printed on a label on the rear of the server. This
server has a range of six MAC addresses assigned to the CIMC. The MAC address printed on
the label is the beginning of the range of six contiguous MAC addresses.
Optional: Use this utility to make VLAN settings, and to set a default CIMC user password.
Changes to the settings take effect after approximately 45 seconds. Refresh with F5 and wait
until the new settings appear before you reboot the server in the next step.
Press F10 to save your settings and reboot the server.
If you chose to enable DHCP, the dynamically assigned IP and MAC addresses are displayed on
the console screen during bootup.

Installing the Server
Initial Server Setup
Step 4
Connect to the CIMC for server management. Connect Ethernet cables from your LAN to the server by
using the ports that you selected by your NIC Mode setting in Step 3. The Active-active and
Active-passive NIC redundancy settings require you to connect to two ports.
Step 5
Use a browser and the IP address of the CIMC to connect to the CIMC Setup Utility. The IP address is
based upon the settings that you made in Step 3 (either a static address or the address assigned by your
DHCP server).
Note
The default user name for the server is admin. The default password is password.
To manage the server, see the Cisco UCS C-Series Rack-Mount Server Configuration Guide or the Cisco
UCS C-Series Rack-Mount Server CLI Configuration Guide for instructions on using those interfaces.

Shutting Down and Powering Off the Server
The server can run in two power modes:
•
Main power mode—Power is supplied to all server components and any operating system on your
drives can run.
•
Standby power mode—Power is supplied only to the service processor and the cooling fans and it
is safe to power off the server from this mode.
You can invoke a graceful shutdown or an hard shutdown by using either of the following methods:
Step 1
Step 2
Caution
Step 3
•
Use the CIMC management interface.
•
Use the Power button on the server front panel. To use the Power button, follow these steps:
Check the color of the Power Status LED (see the “Front Panel LEDs” section on page 3-2).
•
Green—the server is in main power mode and must be shut down before it can be safely powered
off. Go to Step 2.
•
Amber—the server is already in standby mode and can be safely powered off. Go to Step 3.
Invoke either a graceful shutdown or a hard shutdown:
To avoid data loss or damage to your operating system, you should always invoke a graceful shutdown
of the operating system.
•
Graceful shutdown—Press and release the Power button. The operating system performs a graceful
shutdown and the server goes to standby mode, which is indicated by an amber Power Status LED.
•
Emergency shutdown—Press and hold the Power button for 4 seconds to force the main power off
and immediately enter standby mode.
Disconnect the power cords from the power supplies in your server to completely power off the server.

•
Memory Performance Guidelines and Population Rules, page 3-20
•
DIMM Replacement Procedure, page 3-23
Caution
DIMMs and their sockets are fragile and must be handled with care to avoid damage during installation.
Caution
Cisco does not support 3rd-party DIMMs. Using non-Cisco DIMMs in the server might result in system
problems or damage to the motherboard.
Note
To ensure the best server performance, it is important that you are familiar with memory performance
guidelines and population rules before you install or replace memory.
Memory Performance Guidelines and Population Rules
This section describes the type of memory that the server requires and its effect on performance. The
section includes the following topics:
•
DIMM Slot Numbering, page 3-20
•
DIMM Population Rules, page 3-21

DIMM Population Rules
Observe the following guidelines when installing or replacing DIMMs:
•
Each CPU supports three memory channels.
– CPU1 supports channels A, B, and C.
– CPU2 supports channels D, E, and F
Note
•
In a single-CPU system, the maximum number of DIMMs is six (only the six slots supported
by CPU1).
Each channel has two DIMM slots (for example, channel A = slots A0 and A1).
– A channel can operate with one or two DIMMs installed.
– If a channel has only one DIMM, populate slot 0 first (the blue slot).
•
When both CPUs are installed, populate the DIMM slots of each CPU identically.
– Fill blue slots in the channels first: A0, D0, B0, E0, C0, F0
– Fill black slots in the channels second: A1, D1, B1, E1, C1, F1
•
Any DIMM installed in a DIMM socket for which the CPU is absent is not recognized. In a
single-CPU configuration, populate the channels for CPU1 only.

•
Although 1600 MHz DIMMs can be run in Power Savings Mode (1.35 V operation), 1600 MHz
operation is supported only when the DDR mode is set to Performance Mode (see “Enabling
Low-Voltage DIMM Operation.”) A 1600 MHz DIMM set to Power Savings Mode operates at
1066 MHz.
•
Observe the DIMM mixing rules shown in Table 3-3.
Table 3-3
DIMM Mixing Rules
DIMM Parameter Mixed
Mix Across Single Channel?
Mix Across Multiple Channels?
DIMM size (4, 8, 16 GB)
No—Must be same size in
channel.
Yes—Can be different sizes in server.
DIMM speed (1333 or
1600 MHz)
No—Must be same speed in 
channel.
No—Must be the same speed in server.
DIMM type (RDIMM or
UDIMM)
No—Must be same type in
channel.
No—Must be the same type in server.
•
Memory mirroring reduces the amount of memory available by 50% because only one of the two
populated channels provides data. When memory mirroring is enabled, DIMMs must be installed in
sets of four as described in Memory Mirroring, page 3-23.
•
Note the following restrictions when using UDIMMs. Even though a UDIMM might be rated at
1600 MHz, actual operational speeds are slower because of the Intel implementation.
– In Performance Mode (1.5 V operation), UDIMMs run at 1333 MHz in 1 DPC configurations
or at 1066 MHz in 2 DPC configurations.
– In Power Saving Mode (1.35 V operation), UDIMMs run at 1333 MHz in 1 DPC configurations
or at 1066 MHz in 2 DPC configurations.
Enabling Low-Voltage DIMM Operation
You can enable low voltage (1.35 V) DIMM operation for all DIMMs in the server. There is a setting in
the BIOS Setup utility that you can use to change the DDR memory mode to Power Saving mode, as
described in the following procedure:
Step 1
Enter the BIOS setup utility by pressing the F2 key when prompted during bootup.
Step 2
Select the Advanced tab.
Step 3
Select Low Voltage DDR Mode.
Step 4
In the pop-up window, select either Power Saving or Performance Mode:
Step 5
•
Power Saving Mode–Prioritizes low-voltage memory operation.
•
Performance Mode–Prioritizes performance memory operation. If you mix low-voltage DIMMs
with standard DIMMs, the system defaults to this setting.
Press F10 to save your changes and exit the setup utility.

Memory Mirroring
When memory mirroring is enabled, the memory subsystem simultaneously writes identical data to two
channels. If a memory read from one of the channels returns incorrect data due to an uncorrectable
memory error, the system automatically retrieves the data from the other channel. A transient or soft
error in one channel does not affect the mirrored data, and operation continues unless there is a
simultaneous error in exactly the same location on a DIMM and its mirrored DIMM. Memory mirroring
reduces the amount of memory available to the operating system by 50% because only one of the two
populated channels provides data.
If you choose to enable memory mirroring, populate the DIMM slots in the order shown in Table 3-4 or
Table 3-5.

Installing Multiple PCIe Cards and Resolving Limited Resources
When a large number of PCIe add-on cards are installed in the server, the system may run out of the
following resources required for PCIe devices:
•
Option ROM memory space
•
16-bit I/O space
The topics in this section provide guidelines for resolving the issues related to these limited resources.
•
Resolving Insufficient Memory Space to Execute Option ROMs, page 3-37
•
Resolving Insufficient 16-Bit I/O Space, page 3-38
Resolving Insufficient Memory Space to Execute Option ROMs
The system has very limited memory to execute PCIe legacy option ROMs, so when a large number of
PCIe add-on cards are installed in the server, the system BIOS might not able to execute all of the option
ROMs. The system BIOS loads and executes the option ROMs in the order that the PCIe cards are
enumerated (Slot 1, Slot 2, Slot 3, etc.).
If the system BIOS does not have sufficient memory space to load any PCIe option ROM, it skips loading
that option ROM, reports a system event log (SEL) event to the CIMC controller and reports the
following error in the Error Manager page of the BIOS Setup utility:
ERROR CODE SEVERITY
146
Major
INSTANCE
N/A
DESCRIPTION
PCI out of resources error.
Major severity requires user
intervention but does not
prevent system boot.
To resolve this issue, disable the Option ROMs that are not needed for system booting. The BIOS Setup
Utility provides the setup options to enable or disable the Option ROMs at the PCIe slot level for the
PCIe expansion slots and at the port level for the onboard NICs. These options can be found in the BIOS
Setup Utility Advanced PCI Configuration page.
•
Guidelines for RAID controller booting:
If the server is configured to boot primarily from RAID storage, make sure that the option ROMs
for the slots where your RAID controllers installed are enabled in the BIOS, depending on your
RAID controller configuration.
If the RAID controller does not appear in the system boot order even with the option ROMs for those
slots are enabled, the RAID controller option ROM might not have sufficient memory space to
execute. In that case, disable other option ROMs that are not needed for the system configuration to
free up some memory space for the RAID controller option ROM.
•
Guidelines for onboard NIC PXE booting:
If the system is configured to primarily perform PXE boot from onboard NICs, make sure that the
option ROMs for the onboard NICs to be booted from are enabled in the BIOS Setup Utility. Disable
other option ROMs that are not needed to create sufficient memory space for the onboard NICs.

Resolving Insufficient 16-Bit I/O Space
The system has only 64 KB of legacy 16-bit I/O resources available. This 64 KB of I/O space is divided
between the CPUs in the system because the PCIe controller is integrated into the CPUs. This server
BIOS has the capability to dynamically detect the 16-bit I/O resource requirement for each CPU and then
balance the 16-bit I/O resource allocation between the CPUs accordingly during the PCI bus
enumeration phase of the BIOS POST.
When a large number of PCIe cards are installed in the system, the system BIOS might not have
sufficient I/O space for some PCIe devices. If the system BIOS is not able to allocate the required I/O
resources for any PCIe devices, the following symptoms have been observed:
•
The system might get stuck in an infinite reset loop.
•
The BIOS might appear to hang while initializing PCIe devices.
•
The PCIe option ROMs might take excessive time to complete, which appears to lock up the system.
•
PCIe boot devices might not be accessible from the BIOS.
•
PCIe option ROMs might report initialization errors. These errors are seen before the BIOS passes
control to the operating system.
•
The keyboard might not work.
To work around this problem, rebalance the 16-bit I/O load using the following methods:
1.
Physically remove any unused PCIe cards.
2.
If the system has one or more Cisco virtual interface cards (VICs) installed, disable the PXE boot
on the VICs that are not required for the system boot configuration by using the Network Adapters
page in the CIMC WebUI to free up some 16-bit I/O resources. Each VIC uses a minimum 16 KB
of 16-bit I/O resource, so disabling PXE boot on Cisco VICs would free up some 16-bit I/O
resources that can be used for other PCIe cards that are installed in the system.

Note
VMware ESX/ESXi or any other virtualized environments are not supported for use with the embedded
MegaRAID controller. Hypervisors such as Hyper-V, Xen, or KVM are also not supported for use with
the embedded MegaRAID controller.
Note
The embedded RAID option is available only with the SFF 16-drive backplane. It does not operate
through an expander.
This server includes an embedded RAID controller with two mini-SAS connectors on the motherboard
(see Figure C-1).
•
The default setting for this embedded controller is RAID 0, 1, and 10 support for up to four SATA
drives.
•
You can upgrade this support to SAS RAID 0, 1, and 10 support for up to eight SAS drives by
installing a Storage Controller Unit (SCU) upgrade ROM chip on the motherboard. See Installing a
SCU Upgrade ROM Module For Embedded RAID SAS Support, page C-7.
•
You can upgrade this support by adding SAS RAID 5 support with an optional software key. See
Installing a Software RAID Key Module for Embedded RAID 5 Support, page C-8.
Note
You cannot downgrade from using a RAID controller card to using the embedded controller (see RAID
Controller Migration, page C-4). Instructions for installing upgrade modules and enabling the embedded
controller in the BIOS are included here for those upgrading a server with no RAID controller or drives.
Caution
Data migration from SW RAID (embedded RAID) to HW RAID (a controller card) is not supported and
could result in data loss. Migrations from SW RAID to HW RAID are supported only before there is data
on the drives, or the case in which there are no drives in the server (see RAID Controller Migration,
page C-4).
•
You can migrate from using the embedded controller to using a RAID card only before there is data
on the drives. In this case, you must disable the embedded controller. See Disabling the Integrated
RAID Controller in the BIOS, page C-8.
•
The required drivers for this controller are already installed and ready to use with the LSI SWRAID
Configuration Utility. However, if you will use this controller with Windows or Linux, you must
download and install additional drivers for those operating systems. See Installing LSI MegaSR
Drivers For Windows and Linux, page C-9.

Notes on Supported Embedded MegaRAID Levels
The following RAID levels are supported by the embedded MegaRAID controller.
•
RAID 0—You can configure a RAID 0 virtual drive (VD) using one or more physical drives (PDs).
This level supports up to eight VDs and PDs.
•
RAID 1—A RAID 1 VD is configured from only two PDs. This level supports up to eight PDs (four
RAID arrays) and eight VDs.
•
RAID 5—You can configure a RAID 5 VD using three or more PDs. This level supports up to eight
PDs and eight VDs.
•
RAID 10—This is a spanned VD; that is, RAID 0 is implemented on two or more RAID 1 VDs. This
level supports up to eight PDs (two to four RAID 1 volumes spanned) and one VD.
Note
None of these RAID levels require drives of the same size. The smallest drive in the array determines
the size of the VD.
Note
An array can be divided into multiple VDs of the same RAID level, except when using RAID 10. Mixed
arrays are not permitted. For example, you cannot configure a three-drive array into RAID 0 and RAID 5
VDs. Unlike RAID 0, 1, and 5, you cannot create multiple RAID 10 VDs from the same array. A single
RAID 10 VD uses up the entire array.
