Chapter 2. Preparing the BladeCenter unit

This chapter describes the tasks that you must perform before you can use the BladeCenter unit with the blade server.

Preinstallation checklist

Before you can use the BladeCenter unit with the blade server, you must correctly set up and configure the BladeCenter unit, and install and configure the required components in the BladeCenter unit. If you have not already done so, perform the activities on the following checklist:

Set up the rack in which you will install the BladeCenter unit. Install the BladeCenter unit in a rack. For additional information, see the

Rack Installation Instructions that come with the BladeCenter unit.

Install and configure the required BladeCenter unit components:

Make sure that the BladeCenter unit has adequate power to support all the installed devices. The BladeCenter unit must contain either two

four power modules. If necessary, upgrade the power modules in

the BladeCenter unit. For additional information, see the IBM

Eserver BladeCenter Power Module Upgrade Guidelines Technical

Update. Install and configure one or two management modules in the

BladeCenter unit.

Install and configure one or two Ethernet switch modules in the BladeCenter unit.

support the Serial Over LAN (SOL) feature on any blade server

that is installed in the BladeCenter unit:

SOL-compatible Ethernet switch module must be installed in I/O

bay 1 of the BladeCenter unit. Both the BladeCenter unit and the Ethernet switch module must be

configured so that the SOL feature is enabled and set to operate on the same virtual local area network (VLAN).

you plan to install the operating system through the Ethernet network, you also must install and configure a second Ethernet switch module in I/O bay 2 of the BladeCenter unit.

Note: If you install other Ethernet switch modules, they do not have

the same type that you installed in I/O bay 1 of the

BladeCenter unit.

Configure the BladeCenter unit for SOL operation as described in the

IBM Eserver BladeCenter and BladeCenter T Serial Over LAN Setup Guide.

Verify that the firmware code for the BladeCenter unit, management module, and Ethernet switch modules supports the SOL feature. If you are not sure whether these devices come with this feature, see the

help ensure proper cooling, performance, and system reliability, do not operate the BladeCenter unit for more than 1 minute without a blade server or filler blade installed in each blade bay.

When you remove a filler blade from a blade bay in the BladeCenter unit so that you can install a blade server, do not discard the filler blade. You will need the filler blade if you ever remove the blade server. For future use, store the filler blade in a static-protective environment, such as the static-protective package that comes with the blade server.

Attention: If you plan to remove a blade server and reinstall it, be sure to note

the number of the bay that contains the blade server before you remove it. Then, reinstall the blade server in the same bay from which it was removed. Reinstalling a blade server into a different bay than the one from which it was removed could have unintended consequences, such as incorrectly reconfiguring the blade server. Some blade server configuration information and update options are established according to bay number. If you reinstall the blade server into a different bay, you might have to reconfigure the blade server.

This chapter contains the configuration tasks that you must perform so that you can run Serial Over LAN (SOL) sessions on the blade server and use the IBM Eserver BladeCenter management-module command-line interface. This chapter also describes other configuration requirements for the blade server.

After you install the blade server in the BladeCenter unit, the blade server is automatically configured. The Broadcom Ethernet controller device driver is installed after you install the operating system. The blade server is automatically reconfigured after you install software or hardware. IBM will periodically make firmware updates available for the blade server. Before you continue, you can make sure that the blade server has the latest version of firmware code. For additional information, see “Updating the firmware code for the blade server and the service processor” on page 20.

Since the firmware code in the blade server uses auto-configuration, additional blade-server configuration programs are not required for the blade server. However,

you have attached other devices to the blade server or the BladeCenter unit, you must configure those devices as described in the applicable documentation that comes with those devices or the BladeCenter unit. You do not have to set any passwords to use the blade server. If you change the battery or replace the system-board assembly, you must reset the date and time through your operating system.

Configuring the Gigabit Ethernet controller

One dual-port Gigabit Ethernet controller is integrated on the blade server system board. Each controller port provides a 1000-Mbps full-duplex interface for connecting to one of the Ethernet-compatible switch modules in I/O bays 1 and 2, which enables simultaneous transmission and reception of data on the Ethernet local area network (LAN). Each Ethernet-controller port on the system board is routed to a different switch module in I/O bay 1 or bay 2. The routing from the Ethernet-controller port to the I/O bay will vary according to whether an Ethernet adapter is enabled and the operating system that is installed. See “Blade server Ethernet controller enumeration” on page 18 for information about how to determine the routing from the Ethernet-controller ports to I/O bays for your blade server.

Note: Other types of blade servers, such as the BladeCenter HS20 Type 8678, that

are installed in the same BladeCenter unit as this BladeCenter JS20 Type 8842 might have different requirements for Ethernet controller routing. See the documentation that comes with the other blade servers for detailed information.

For updated information about configuring the controllers, go to the IBM Support Web site at http://www.ibm.com/pc/support/.

Blade server Ethernet controller enumeration

The enumeration of the Ethernet controllers or controller ports in a blade server is operating-system dependent. You can verify the Ethernet controller or controller port designations that a blade server uses through your operating-system settings.

The routing of an Ethernet controller or controller port to a particular BladeCenter unit I/O bay depends on the type of Ethernet expansion card that is installed. You can verify which Ethernet-controller port in this blade server is routed to which I/O bay by using the following test:

Install only one Ethernet switch module or pass-thru module, in I/O bay 1. Make sure that the ports on the switch module or pass-thru module are enabled

(Switch Tasks → Management → Advanced Switch Management in the BladeCenter management-module Web interface).

Enable only one of the Ethernet-controller ports on the blade server. Note the designation that the blade server operating system has for the controller port.

Ping an external computer on the network connected to the Ethernet switch module. If you can ping the external computer, the Ethernet-controller port that you enabled is associated with the switch module in I/O bay 1. The other Ethernet-controller port in the blade server is associated with the switch module

I/O bay 2.

Communications from optional Ethernet adapters and other I/O expansion cards are routed to I/O bays 3 and 4. You can verify which controller port on an expansion card is routed to which I/O bay by performing the same test, using a controller on the expansion card and a compatible switch module or pass-thru module in I/O bay

Chapter 7. Installing and removing options and customer-replaceable units

This chapter provides instructions for adding options or customer-replaceable units (CRUs) to the blade server. CRUs are customer-replaceable components, such as memory modules, hard disk drives, and I/O expansion cards. (Some removal instructions are provided in case you need to remove one option or CRU to install another.)

Installation guidelines

Before you begin, read the following information:

Read the safety information beginning on page vii and the guidelines in “Handling static-sensitive devices” on page 32. This information will help you work safely with the blade server and options.

Read the information in “Preinstallation checklist” on page 7. Back up all important data before you make changes to disk drives. Have a small flat-blade screwdriver and a Phillips screwdriver available. You do not have to turn off the blade server or disconnect the BladeCenter unit

from power to install or replace any of the hot-swap modules on the rear of the BladeCenter unit.

Before you remove a hot-swap blade server from the BladeCenter unit, you must shut down the operating system by typing the shutdown -h now command. If the blade server was not turned off, press the power-control button (behind the blade-server control-panel door) to turn off the blade server. You do not have to shut down the BladeCenter unit itself.

remove it from or install it in the blade server or BladeCenter unit, open or close a latch, and so on.

Orange on a component or an orange label on or near a component indicates that the component can be hot-swapped, which means that if the blade server or BladeCenter unit and operating system support hot-swap capability, you can remove or install the component while the blade server or BladeCenter unit is running. (Orange can also indicate touch points on hot-swap components.) See the instructions for removing or installing a specific hot-swap component for any additional procedures that you might have to perform before you remove or install the component.

For a list of supported options for the blade server, go to http://www.ibm.com/pc/us/compat/.

System reliability guidelines

help ensure proper cooling and system reliability, make sure that: The ventilation holes on the blade server are not blocked. Each of the blade bays on the front of the BladeCenter unit has a blade server or

filler blade installed. Do not operate the BladeCenter unit for more than 1 minute without a blade server or filler blade installed in each blade bay.

You have followed the reliability guidelines in the documentation that comes with the BladeCenter unit.

v Do

You have not installed any small computer system interface (SCSI) devices. The blade server does not support SCSI devices. If you attach SCSI devices to the blade server, these devices will not be recognized or configured, and they will not operate.

Handling static-sensitive devices

Attention: Static electricity can damage electronic devices and your system. To

avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them.

reduce the possibility of electrostatic discharge, observe the following

precautions:

Limit your movement. Movement can cause static electricity to build up around you.

Handle the device carefully, holding it by its edges or its frame.

not touch solder joints, pins, or exposed printed circuitry. not leave the device where others can handle and damage it.

While the device is still in its static-protective package, touch it to an unpainted metal part of the BladeCenter chassis for at least 2 seconds. This drains static electricity from the package and from your body.

Remove the device from its package and install it directly into the blade server or BladeCenter unit without setting the device down. If it is necessary to set down the device, put it back into its static-protective package. Do not place the device

the blade server cover or on a metal surface.

Take additional care when handling devices during cold weather. Heating reduces indoor humidity and increases static electricity.

“Completing the installation” on page 48.

Installing memory modules

You can increase the amount of memory in the blade server by installing additional memory-module options. When you install memory, you must install a pair of matched dual inline memory modules (DIMMs).

Notes:

The system board contains four DIMM connectors and supports two-way memory interleaving.

The DIMM options available for the blade server are 256 MB, 512 MB, and 1 GB. The blade server supports a minimum of 512 MB and a maximum of 4 GB of system memory.

Both DIMMs in a pair must be the same size, speed, type, and technology. You can mix compatible DIMMs from various manufacturers.

The second pair of DIMMs does not have to be the same size, speed, type, and technology as the first pair.

The blade server does not support unregistered DIMMs. Install only 2.5 V, 184-pin, double-data-rate (DDR), PC2700, registered synchronous dynamic random-access memory (SDRAM) with error correcting code (ECC) DIMMs. These DIMMs must be compatible with the latest PC2700 SDRAM Registered DIMM PC2700, which is available from http://www.jedec.org/. For a list of supported options for the blade server, go to http://www.ibm.com/pc/us/compat/.

Installing or removing DIMMs changes the configuration information for the blade server. After you install or remove a DIMM, the new configuration information is automatically saved in the blade server firmware code.

9. “Completing the installation” on page 48.

Installing an I/O expansion card

You can add an optional I/O expansion card (adapter) to the blade server to give the blade server additional network connections for communicating on a network.

When you add an I/O expansion card, you must make sure that the switch modules

I/O bays 3 and 4 on the BladeCenter unit both support the I/O expansion card network-interface type. For example, if you add an Ethernet expansion card to the blade server, the modules in I/O bays 3 and 4 on the BladeCenter unit must both

compatible with the Ethernet expansion card. All other I/O expansion cards installed on other blade servers in the BladeCenter unit must also be compatible with these switch modules. In this example, you could then install two Ethernet switch modules, two pass-thru modules, or one Ethernet switch module and one pass-thru module. Because pass-thru modules are compatible with a variety of I/O expansion cards, installing two pass-thru modules would allow use of several different types of compatible I/O expansion cards within the same BladeCenter unit.

Important:

Installation of an I/O expansion card requires removal of the hard disk drive that

installed in IDE connector 2. The I/O expansion card occupies the same space

this hard disk drive and replaces it. You cannot install a hard disk drive in IDE

connector 2 while an I/O expansion card is installed in the blade server. The Myrinet Cluster Expansion Card for IBM Eserver BladeCenter comes with a

cable for connection to the system board of a compatible device. However, the cable is not used in the BladeCenter JS20 Type 8842. Therefore, when you install a Myrinet Cluster Expansion Card for IBM Eserver BladeCenter into a BladeCenter JS20 Type 8842, do not connect the cable from the I/O expansion card to the system board.

you plan to install a Fibre Channel expansion card and use it for remote startup (boot) operations, call the IBM Support Center for additional information. In the U.S. and Canada, call 1-800-IBM-SERV (1-800-426-7378). In other countries, go

Ethernet controller, switch module, and cabling requirements

One dual-port Gigabit Ethernet controller is integrated on the BladeCenter JS20 Type 8842 system board. To support Ethernet connections and the Serial Over LAN (SOL) feature and to configure the blade server, you must install an optional Ethernet-compatible switch module, such as the Nortel Networks Layer 2-7 GbE Switch Module for IBM Eserver BladeCenter or IBM 4-Port Gb Ethernet Switch Module for BladeCenter, in I/O bay 1 of the BladeCenter unit.

Each controller port provides a 1000-Mbps full-duplex interface for connecting to one of the Ethernet-compatible switch modules in I/O bays 1 and 2. If you plan to attach additional Ethernet devices to the blade server or the BladeCenter unit, you must install an optional Ethernet-compatible switch module, such as the Nortel Networks Layer 2-7 GbE Switch Module for IBM Eserver BladeCenter or IBM 4-Port Gb Ethernet Switch Module for BladeCenter, in I/O bay 3 or 4 of the BladeCenter unit, to support these additional Ethernet connections.

The optional Ethernet switch modules contain four ports with RJ-45 connectors. These connectors provide a 10/100/1000 Base-T interface (either at half-duplex or full duplex) for connecting twisted-pair cable to the Ethernet network. You must purchase and install a compatible cable to connect these devices. To connect an Ethernet controller port to a repeater or switch module, use an unshielded twisted pair (UTP) cable with RJ-45 connectors at both ends. For 100 Mbps or higher operation, Category 5 cabling is required. For 10 Mbps operation, Category 3 or Category 5 cabling is required.

Notes:

For more information about Ethernet requirements, see the documentation that

comes with the Ethernet devices and the BladeCenter Type 8677 Installation and User’s Guide.

For more information about installing, configuring, and using the Ethernet switch modules, see the documentation that comes with the Ethernet switch module that you are using, such as the IBM 4-Port Gb Ethernet Switch Module for

Replacing the system-board assembly

Two operational microprocessors and heat sinks are required on the system-board assembly in the blade server at all times. The microprocessors and heat sinks are not replaceable. Do not attempt to remove these components or any components that secure the microprocessors and heat sinks to the system-board assembly. You must replace the system-board assembly if any of these conditions exists:

microprocessor or heat sink becomes defective. Certain errors occur as described in “Firmware error codes” on page 75. The blade server does not restart after you recover the system firmware code as

described in “Recovering the system firmware code” on page 95.

obtain a new system-board assembly for the blade server, you must call the IBM

To Support Center to report the original system-board assembly as a failed part. The IBM Support Center team will evaluate the problem and determine whether the blade server requires a replacement system-board assembly or other service. If the IBM Support Center team determines that the blade server requires a replacement system-board assembly, they will send a replacement system-board assembly to you. Before you call, make sure that you know the following information about the blade server: machine type, model number, and serial number. Locate this information on the identification label that is behind the control-panel door on the front of the blade server. You must provide this information when you call the IBM Support Center. In the U.S. and Canada, call 1-800-IBM-SERV (1-800-426-7378). In other countries, go to http://www.ibm.com/planetwide/ to locate your support telephone numbers. If the IBM Support Center team determines that the blade server requires other service, you must contact an IBM authorized service technician.

Note: The new system-board assembly comes attached to a blade server chassis.

Important: After you replace the system-board assembly, you must either update

the blade server with the latest firmware or restore the pre-existing firmware from a diskette or CD image. You must also configure the blade server and use the operating system to reset the system date and time.

serial number of the blade server (with the original system-board assembly) onto the RID tag label in this step. The part number for the RID tag is 13N0477.

Use the RID tag label to transfer entitlement (machine type, model number, and serial number) from the original system-board assembly to the new system-board assembly. Do not use a pencil or felt-tip pen to complete the RID tag label.

Important:

The serial number of the blade server (with the original system-board assembly) must match the serial number that you reported when you called IBM for service.

Because the new system-board assembly is not associated with a blade-server serial number, you must transfer the serial number from the original system-board assembly to the new system-board assembly. The first time that you turn on the blade server that contains the new system-board assembly, the firmware code will request that you enter the serial number,

described in step 16. You must enter the blade-server serial number. If you enter a different serial number, the operating system that you installed might interpret this information as an incorrect serial number, and you might have to change your software-licensing agreement.
