Cisco UCS B200 Blade Server Installation and Service Note
The UCS B200 blade server (shown in ) is now only available in the M2 version (the M1 version is no longer sold as of 1/21/2011). The procedures in this document apply to both versions. The Cisco UCS B200 is a half-width blade with 12 DIMM it supports one adapter. You may install up to eight UCS B200 Blade Servers to a UCS chassis.

The LED indicators indicate whether the blade server is in active or standby mode, the status of the network link, the over all health of the blade server, and whether the server is set to give a flashing blue beaconing indication. See
for details.
The removable hard disks also have LEDs indicating hard disk access activity and hard disk health.

The Reset button is just inside the chassis and must be pressed using the tip of a paper clip or a similar item. Hold the button down for five seconds and then release it to restart the server if other methods of restarting are not working.
The beaconing function for an individual server may get turned on or off by pressing the combination button and LED. See
for details.
The power button and LED allows you to manually take a server temporarily out of service but leave it in a state where it can be restarted quickly. If the desired power state for a service profile associated with a blade server or an integrated rack-mount server is set to &off&, using the power button or Cisco UCS Manager to reset the server will cause the desired power state of the server to become out of sync with the actual power state and the server may unexpected shutdown at a later time. To safely reboot a server from a power-down state, use the Boot Server action in Cisco UCS Manager.
A console port is provided to give a direct connection to a blade server to allow operating system installation and other management tasks to be done directly rather than remotely. The port uses the KVM dongle device included in the chassis accessory kit.
The KVM cable (N20-BKVM shown in ) provides a connection into a Cisco UCS blade server, providing a DB9 serial connector, a VGA connector for a monitor, and dual USB ports for a keyboard and mouse. With this cable you can create a direct connection to the operating system and the BIOS running on a blade server.

GEM DISSE ANVISNINGER
There are up to 2 front-accessible, hot-swappable, 2.5-inch drives per blade. An LSI 1064E RAID controller is embedded in the motherboard (it is not separately replaceable) and it supports RAID 0 and 1. You can remove blade server hard drives without removing the blade server from the chassis. All other component replacement for a blade server requires removing the blade from the chassis. Unused hard drive bays should always be covered with cover plates (N20-BBLKD) to assure proper cooling and ventilation. The chassis is omitted from illustrations here to simplify the drawing.
To prevent ESD damage, wear grounding wrist straps during these procedures and handle modules by the carrier edges only.
Note Seagate SATA disks and Intel or Samsung SATA SSDs are not supported in UCS Manager release 1.2(1) and can not be used with servers using UCS Manager release 1.2(1).
RAID array migration between a B200 M1 or B200 M2 and a B200 M3 is not supported
Replacing an HDD or SSD with a drive of the same size, model, and manufacturer generally causes few problems with UCS Manager. If the drive being replaced was part of a RAID array we recommend using a newly ordered drive of identical size, model, and manufacturer to replace the failed drive. Cisco recommends following industry standard practice of using drives of the same capacity when creating RAID volumes. If drives of different capacities are used, the useable portion of the smallest drive will be used on all drives that make up the RAID volume. Before upgrading or adding an HDD to a running system, check the service profile in UCS Manager and make sure the new hardware configuration will be within the parameters allowed by the service profile.
Hard disk and RAID troubleshooting information is in the &Troubleshooting Server Hardware& chapter of the .

To remove a hard drive from a blade server, follow these steps:
Step&1 Push the button to release the ejector, and then pull the hard drive from its slot.
Figure&3 Removing the Hard Drive
Step&2 Place the hard drive on an antistatic mat or antistatic foam if you are not immediately reinstalling it in another blade server.
Step&3 Install a blank faceplate (N20-BBLKD) to keep dust out of the blade server if the slot will remain empty.
To install a blade server hard drive in a blade server, follow these steps:
Step&1 Place the hard drive lever into the open position by pushing the release button (see ).
Figure&4 Installing a Hard Drive in a Blade Server
Step&2 Gently slide the hard drive into the opening in the blade server until it seats into place.
Step&3 Push the hard drive lever into the closed position.
You can use UCS Manager to format and configure RAID services. refer to the UCS Manager configuration guide for your software release for details on RAID configuration.
If you need to move a RAID cluster, refer to the
section of the &Troubleshooting Server Hardware& chapter of the Cisco UCS Troubleshooting Guide.
Before performing any internal operation on a blade server, you must remove it from the chassis. To prevent ESD damage, wear grounding wrist straps during these procedures and handle modules by the carrier edges only.
To prevent ESD damage, wear grounding wrist straps during these procedures and handle modules by the carrier edges only.
The server can run in two power modes:
oMain power mode—Power is supplied to all server components and any operating system on your hard drives can run.
oStandby 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.
After establishing a connection to the blade server's operating system, you can directly shut down the blade server using the operating system.
You can invoke a graceful shutdown or an emergency shutdown (hard shutdown) by using either of the following methods:
oUse the UCS Manager. See either the Cisco UCS Manager GUI Configuration Guide or the Cisco UCS Manager CLI Configuration Guide.
oUse the Power button on the server front panel. To use the Power button, follow these steps:
Step&1 Check the color of the Power Status LED.
oGreen indicates that the server is in main power mode and must be shut down before it can be safely powered off. Go to Step 2.
oAmber indicates that the server is already in standby mode and can be safely powered off. Go to Step&3.
Step&2 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.
oGraceful shutdown—Press and release the Power button. The operating system will perform a graceful shutdown and the server goes to standby mode, which is indicated by an amber Power Status LED.
oEmergency shutdown—Press and hold the Power button for 4 seconds to force the main power off and immediately enter standby mode.
Step&3 If you are shutting down all blade servers in a chassis, you should now disconnect the power cords from the chassis to completely power off the servers. If you are only shutting down one server, you can skip unplugging the chassis and move to removing the server.
Using UCS Manager, decommission the server using UCS Manager before physically removing the server. To remove a blade server from the chassis, follow these steps:
Step&1 Loosen the captive screw on the front of the blade.
Step&2 Remove the blade from the chassis by pulling the ejector lever on the blade until it unseats the blade server.
Step&3 Slide the blade part of the way out of the chassis, and place your other hand under the blade to support its weight.
Step&4 Once removed, place the blade on an antistatic mat or antistatic foam if you are not immediately reinstalling it into another slot.
Step&5 If the slot is to remain empty, install a blank faceplate (N20-CBLKB1) to keep dust out of the chassis.
To install a blade server, follow these steps:
Step&1 Grasp the front of the blade server and place your other hand under the blade to support it. See .
Figure&5 Positioning a Blade Server in the Chassis
Step&2 Open the ejector lever in the front of the blade server.
Step&3 Gently slide the blade into the opening until you cannot push it any farther.
Step&4 Press the ejector lever so that it catches the edge of the chassis and presses the blade server all the way in.
Step&5 Tighten the captive screw on the front of the blade to no more than 3 in-lbs. Tightening with bare fingers only is unlikely to lead to stripped or damaged captive screws.
Step&6 Power on the server. UCS Manager will automatically re acknowledge, reassociate, and recommission the server, provided any hardware changes are allowed by the service profile.

At blade start-up, POST diagnostics test the CPUs, DIMMs, HDDs and adapter cards, and any failure notifications are sent to UCS Manager. You can view these notifications in the System Error Log or in the output of the show tech-support command. If errors are found, an amber diagnostic LED will also light up next to the failed component. During run time, the blade BIOS, component drivers, and OS all monitor for hardware faults and will light up the amber diagnostic LED for a component if an uncorrectable error or correctable errors (such as a host ECC error) over the allowed threshold occur.
LED states are saved, and if you remove the blade from the chassis the LED values will persist for up to 10 minutes. Pressing the LED diagnostics button on the motherboard will cause the LEDs that currently show a component fault to light for up to 30 seconds for easier component identification. LED fault values are reset when the blade is reinserted into the chassis and booted, and the process begins from its start.
If DIMM insertion errors are detected, they may cause the blade discovery to fail and errors will be reported in the server POST information, viewable using the UCS Manager GUI or CLI. UCS blade servers require specific rules to be followed when populating DIMMs in a blade server, and the rules depend on the blade server model. Refer to the documentation for a specific blade server for those rules.
HDD status LEDs are on the front face of the HDD. Faults on the CPU, DIMMs, or adapter cards will also cause the server health LED to light solid Amber for minor error conditions or blinking Amber for critical error conditions.
The B200 blade server supports the following Cisco component:
CR2032 battery
N20-MBLIBATT
Warning There is danger of explosion if the battery is replaced incorrectly. Replace the battery only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer's instructions.Statement&1015
To install or replace a motherboard complementary metal-oxide semiconductor (CMOS) battery, follow these steps:
Step&1 Remove a motherboard CMOS battery:
a. Power off the blade, remove it from the chassis, and remove the top cover as described in the .
b. Press the battery socket retaining clip toward the chassis wall (see ).
c. Lift the battery from the socket. Use needle-nose pliers to grasp the battery if there is not enough clearance for your fingers.
Step&2 Install a motherboard CMOS battery:
a. Press the battery socket retaining clip toward the chassis wall.
b. Insert the new battery into the socket with the battery's negative (-) marking toward the chassis wall. Ensure that the retaining clip clicks over the top of the battery.
c. Replace the top cover.
d. Replace the server in the chassis and power on the blade by pressing the Power button.
Figure&9 Removing and Replacing a Motherboard CMOS Battery
You can order your blade server with two CPUs, or upgrade later to a second CPU. Both CPUs must be of the same type, and memory in slots intended for the second CPU will not be recognized if the second CPU is not present (see ). You may need to use these procedures to move a CPU from one server to another, or to replace a faulty CPU.

The server can be ordered with low-voltage (1.35 V) DIMM pairs or standard-voltage (1.5 V) DIMM pairs. Low-voltage DIMM pairs and standard-voltage DIMM pairs can be mixed in the same server. Note that this causes the system BIOS to default to standard-voltage operation (Performance Mode). That is, the server cannot operate in the Power Saving Mode unless all DIMM pairs in the server are low-voltage DIMMs.
There is a setting in the BIOS Setup utility that you can use to change the DDR memory mode when the server has all low-voltage DIMMs installed. To access this setting, follow these steps:
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 Mode or Performance Mode.
oPower Saving Mode-Enables low-voltage memory operation. This setting is available only if all DIMMs installed are low-voltage DIMMs.
oPerformance Mode-Disables low-voltage memory operation. If you mix low-voltage DIMM pairs with standard-voltage DIMM pairs, the system defaults to this setting.
Step&5 Press F10 to save your changes and exit the setup utility, or you can exit without saving changes by pressing Esc.
The blade server contains 12 DIMM slots—six for each CPU. Each set of six DIMM slots is arranged into three channels, where each channel has 2 DIMMs (see
Figure&13 Memory Slots within the Blade Server
Channels D-F for CPU 2
Channels A-C for CPU 1
Each channel is identified by a letter—A, B, C for CPU1, and D, E, F for CPU 2. Each DIMM slot is identified by a number, either 1 or 2. Note that each DIMM slot 1 is blue, while each slot 2 is black.

Each CPU in a Cisco UCS B200 blade server supports 3 channels of 2 memory slots each. In a 1 DPC configuration, DIMMs are in slot 1 only. In a 2 DPC configuration, DIMMs are in both slot 1 and slot 2.
shows the preferred order for installing upgrade DIMMs, and while other configurations may work if problems arise moving them to the preferred arrangement should help.

When considering the memory configuration of your blade server, there are several things you need to consider. For example:
oDIMMs within the blade server should all be the same type. This goes for both speed and size. Do not mix different sized DIMMs or DIMMs with different clock rates in the same blade server. Doing so will cause a significant loss of performance.
oYour selected CPU(s) can have some affect on performance.
oDIMMs can be run in a 1 DIMM per-Channel or a two DIMM per-channel configuration. Each of these arrangements can provide different behavior.
Recommendations for achieving performance of 1333 MHz on B200 M1 servers:
oEnsure the server is running the 1.3(1) or later BIOS version. If a BIOS upgrade is needed, do it before installing processors or memory.
oUse Intel Xeon X5570 or X5550 processors (PIDs N20-X00001 and N20-X00006).
oUse only Cisco certified single or dual rank DIMMs that support 1333 MHz speeds (see ). DIMMs do not have to be identical in type or capacity, but beware of the caveats listed in the section below regarding performance degradation.
oAlways set the system BIOS to operate the DIMMs in &Performance& mode in order to run at 1333&MHz.
oFully populating 1 logical bank or 2 logical banks with DIMMs will ensure optimal memory bandwidth running at the 1333 MHz speed. If DIMMs are partially populated in 1 bank (less than 6 DIMMs) or 2 bank patterns (less than 12 but greater than 6 DIMMs) the 1333 MHz speed can be used, but the overall memory bandwidth will not be optimal.
Recommendations for achieving performance of 1333 MHz on B200 M2 servers:
oUse Intel Xeon X5680, X5670, or X5650 processors (see ).
oUse only Cisco certified single or dual rank DIMMs that support 1333 MHz speeds (see ). DIMMs do not have to be identical in type or capacity, but beware of the caveats listed in the section below regarding performance degradation.
oAlways set the system BIOS to operate the DIMMs in &Performance& mode in order to run at 1333&MHz.
oFully populating 1 bank or 2 banks with DIMMs will ensure optimal memory bandwidth running at the 1333 MHz speed. If DIMMs are partially populated in 1 bank (less than 6 DIMMs) or 2 bank patterns (less than 12 but greater than 6 DIMMs) the 1333 MHz speed can be used, but the overall memory bandwidth will not be optimal.
Performance degradation can occur if the following memory configurations are used:
oMixing DIMM sizes and densities within a channel
oPartially populating a channel
oUnevenly populating DIMMs between CPUs
The Intel Nehalem-EP CPUs within the blade server support memory mirroring only when no more than two Channels are populated with DIMMs. If three Channels are populated with DIMMs, memory mirroring is automatically disabled. Furthermore, if memory mirroring is used, DRAM size is reduced by 50% for reasons of reliability.
If the RAS (Reliability, Availability, and Serviceability) option is required, it is available only when Channel-3 is not populated.
The network adapters and interface cards all have a shared installation process. The following options are available:

If you are switching from one type of adapter card to another, before you physically perform the switch make sure you have downloaded the latest device drivers and loaded them into the server's operating system. For more information refer to the firmware management chapter of one of the UCS Manager software configuration guides.
To install an adapter card on the blade server, follow these steps:
Step&1 Position the adapter board connector above the mother board connector and align the three adapter captive screws to the posts on the motherboard.
Step&2 Firmly press the adapter connector into the motherboard connector.
Step&3 Tighten the three captive screws.
