Guidelines for trained service technicians
This section contains information for trained service technicians.
Inspecting for unsafe conditions
Use the information in this section to help you identify potential unsafe conditions in
an IBM product on which you are working. Each IBM product, as it was designed
and manufactured, has required safety items to protect users and service
technicians from injury. The information in this section addresses only those items.
Use good judgment to identify potential unsafe conditions that might be caused by
non-IBM alterations or attachment of non-IBM features or options that are not
addressed in this section. If you identify an unsafe condition, you must determine
how serious the hazard is and whether you must correct the problem before you
work on the product.
Consider the following conditions and the safety hazards that they present:
v Electrical hazards, especially primary power. Primary voltage on the frame can
cause serious or fatal electrical shock.
v Explosive hazards, such as a damaged CRT face or a bulging capacitor.
v Mechanical hazards, such as loose or missing hardware.
inspect the product for potential unsafe conditions, complete the following steps:
To
1. Make sure that the power is off and the power cord is disconnected.
2. Make sure that the exterior cover is not damaged, loose, or broken, and
observe any sharp edges.
3. Check the power cord:
v Make sure that the third-wire ground connector is in good condition. Use a
meter to measure third-wire ground continuity for 0.1 ohm or less between
the external ground pin and the frame ground.
v Make sure that the power cord is the correct type, as specified in the
documentation for your BladeCenter unit type.
v Make sure that the insulation is not frayed or worn.
Remove the cover.
4.
5. Check for any obvious non-IBM alterations. Use good judgment as to the safety
of any non-IBM alterations.
6. Check inside the server for any obvious unsafe conditions, such as metal filings,
contamination, water or other liquid, or signs of fire or smoke damage.
7. Check for worn, frayed, or pinched cables.
8. Make sure that the power-supply cover fasteners (screws or rivets) have not
been removed or tampered with.
Guidelines for servicing electrical equipment
Observe the following guidelines when servicing electrical equipment:
v Check the area for electrical hazards such as moist floors, non-grounded power
extension cords, and missing safety grounds.
v Use only approved tools and test equipment. Some hand tools have handles that
are covered with a soft material that does not provide insulation from live
electrical current.
v Regularly inspect and maintain your electrical hand tools for safe operational
condition. Do not use worn or broken tools or testers.
viii BladeCenter HS21 Types 1885 and 8853: Problem Determination and Service Guide
v Do not touch the reflective surface of a dental mirror to a live electrical circuit.
The surface is conductive and can cause personal injury or equipment damage if
it touches a live electrical circuit.
v Some rubber floor mats contain small conductive fibers to decrease electrostatic
discharge. Do not use this type of mat to protect yourself from electrical shock.
v Do not work alone under hazardous conditions or near equipment that has
hazardous voltages.
v Locate the emergency power-off (EPO) switch, disconnecting switch, or electrical
outlet so that you can turn off the power quickly in the event of an electrical
accident.
v Disconnect all power before you perform a mechanical inspection, work near
power supplies, or remove or install main units.
v Before you work on the equipment, disconnect the power cord. If you cannot
disconnect the power cord, have the customer power-off the wall box that
supplies power to the equipment and lock the wall box in the off position.
v Never assume that power has been disconnected from a circuit. Check it to
make sure that it has been disconnected.
v If you have to work on equipment that has exposed electrical circuits, observe
the following precautions:
– Make sure that another person who is familiar with the power-off controls is
near you and is available to turn off the power if necessary.
– When you are working with powered-on electrical equipment, use only one
hand. Keep the other hand in your pocket or behind your back to avoid
creating a complete circuit that could cause an electrical shock.
– When using a tester, set the controls correctly and use the approved probe
leads and accessories for that tester.
– Stand on a suitable rubber mat to insulate you from grounds such as metal
floor strips and equipment frames.
Use extreme care when measuring high voltages.
v
v To ensure proper grounding of components such as power supplies, pumps,
blowers, fans, and motor generators, do not service these components outside of
their normal operating locations.
v If an electrical accident occurs, use caution, turn off the power, and send another
person to get medical aid.

Keyboard/video/mouse (KVM) select button: Press this button to associate the
shared BladeCenter unit keyboard port, video port, and mouse port with the blade
server. The LED on this button flashes while the request is being processed, and
then is lit when the ownership of the keyboard, video, and mouse has been
transferred to the blade server. It can take approximately 20 seconds to switch the
keyboard, video, and mouse control to the blade server.
Using a keyboard that is directly attached to the management-module, you can
press keyboard keys in the following sequence to switch KVM control between
blade servers:
NumLock NumLock blade_server_number Enter
Where blade_server_number is the two-digit number for the blade bay in which
the blade server is installed. A blade server that occupies more than one blade
bay is identified by the lowest bay number that it occupies.
If there is no response when you press the KVM select button, you can use the
management-module Web interface to determine whether local control has been
disabled on the blade server.
Note:
1. The operating system in the blade server must provide USB support for the
blade server to recognize and use the keyboard and mouse, even if the
keyboard and mouse have PS/2-style connectors.
2. If you install a supported Microsoft Windows operating system on the blade
server while it is not the current owner of the keyboard, video, and mouse, a
delay of up to 1 minute occurs the first time that you switch the keyboard, video,
and mouse to the blade server. All subsequent switching takes place in the
normal KVM switching time frame (up to 20 seconds).

start automatically when power is restored, if the blade server is configured
through the management module to do so.
v Yo u can turn on the blade server remotely by using the management module.
v If the blade server is connected to power (the power-on LED is flashing slowly),
the operating system supports the Wake on LAN® feature, and the Wake on LAN
feature has not been disabled through the management module, the Wake on
LAN feature can turn on the blade server.
Turning off the blade server
When you turn off the blade server, it is still connected to power through the
BladeCenter unit. The blade server can respond to requests from the service
processor, such as a remote request to turn on the blade server. To remove all
power from the blade server, you must remove it from the BladeCenter unit.
Shut down the operating system before you turn off the blade server. See the
operating-system documentation for information about shutting down the operating
system.
The blade server can be turned off in any of the following ways:
v Yo u can press the power-control button on the blade server (behind the control
panel door, see “Blade server controls and LEDs” on page 4). This starts an
orderly shutdown of the operating system, if this feature is supported by the
operating system.
v If the operating system stops functioning, you can press and hold the
power-control button for more than 4 seconds to turn off the blade server.
v The management module can turn off the blade server.
– If the system is not operating correctly, the management module will

Chapter 2. Configuration information and instructions
This chapter provides information about updating the firmware and using the
configuration utilities.
Firmware updates
IBM periodically makes BIOS, service processor (BMC), and diagnostic firmware
updates available for the blade server. Go to http://www.ibm.com/systems/support/
to download the latest firmware for the blade server. Install any updates, using the
instructions that are included with the downloaded file.
Important: To avoid problems and to maintain proper system performance, always
ensure that the blade server BIOS, service processor, and diagnostic firmware
levels are consistent for all blade servers of the same type within the BladeCenter
unit.
Using the Configuration/Setup Utility program
The Configuration/Setup Utility program is part of the BIOS. You can use it to:
v Change interrupt request (IRQ) settings
v Change the startup drive sequence
v Configure serial-port assignments
v Enable USB keyboard and mouse support
v Resolve configuration conflicts
v Set the date and time
v Set passwords and security settings
start the Configuration/Setup Utility program, complete the following steps:
To
1. Turn on the server.
2. When the message Press F1 for Configuration/Setup appears, press F1. If
an administrator password has been set, you must type the administrator
password to access the full Configuration/Setup Utility menu.
3. Follow the instructions on the screen.
Configuring the Gigabit Ethernet controllers
Two Ethernet controllers are integrated on the blade server system board. Each
controller provides a 1-Gbps full-duplex interface for connecting to one of the
Ethernet-compatible switch modules in I/O-module bays 1 and 2, which enables
simultaneous transmission and reception of data on the Ethernet local area network
(LAN). Each Ethernet controller on the system board is routed to a different switch
module in I/O module bay 1 or bay 2. See “Blade server Ethernet controller
enumeration” on page 12 for information about how to determine the routing from
Ethernet controller to I/O-module bay for your blade server.
You do not have to set any jumpers or configure the controllers for the blade server
operating system. However, you must install a device driver to enable the blade
server operating system to address the Ethernet controllers. For device drivers and
information about configuring the Ethernet controllers, see the Broadcom NetXtreme
© Copyright IBM Corp. 2007 11
Gigabit Ethernet Software CD that comes with the blade server. To find updated
information about configuring the controllers, see http://www.ibm.com/systems/
support/
The Ethernet controllers support failover, which provides automatic redundancy for
the Ethernet controllers. Without failover, you can have only one Ethernet controller
from each server attached to each virtual LAN or subnet. With failover, you can
configure more than one Ethernet controller from each server to attach to the same
virtual LAN or subnet. Either one of the integrated Ethernet controllers can be
configured as the primary Ethernet controller. If you have configured the controllers
for failover and the primary link fails, the secondary controller takes over. When the
primary link is restored, the Ethernet traffic switches back to the primary Ethernet
controller. See your operating system device driver documentation for information
about configuring for failover.
Important: To support failover on the blade server Ethernet controllers, the Ethernet
switch modules in the BladeCenter unit must have identical configurations.
Blade server Ethernet controller enumeration
The enumeration of the Ethernet controllers in a blade server is operating-system
dependent. Through the operating-system settings, you can verify the Ethernet
controller designations that a blade server uses.
The routing of an Ethernet controller to a particular I/O-module bay depends on the
type of blade server. Yo u can verify which Ethernet controller is routed to which
I/O-module bay by using the following test:
1. Install only one Ethernet switch module or pass-thru module in I/O-module bay
1.
2. Make sure that the ports on the switch module or pass-thru module are enabled
(I/O Module Tasks → Management → Advanced Management in the
management-module Web interface).
3. Enable only one of the Ethernet controllers on the blade server. Note the
designation that the blade server operating system has for the controller.
4. Ping an external computer on the network that the switch module is connected
to. If you can ping the external computer, the Ethernet controller that you
enabled is associated with the switch module in I/O-module bay 1. The other
Ethernet controller in the blade server is associated with the switch module in
I/O-module bay 2.
If you have installed an expansion card in a blade server, communication from the
expansion card is routed to I/O-module bays 3 and 4, if these bays are supported
by your BladeCenter unit. You can verify which controller on the card is routed to
which I/O-module bay by performing the same test and using a controller on the
expansion card and a compatible switch module or pass-thru module in I/O-module
bay 3 or 4.

Configuring a SAS RAID
Note: Configuring a SAS redundant array of independent disks (RAID) array
applies only to a blade server in which two SAS hard disk drives are installed.
You can configure a SAS RAID array for your blade server. You can use two SAS
hard disk drives in the blade server to implement and manage a RAID level-0
(striping) or RAID level-1 (mirroring) array under an operating system that is listed
at http://www.ibm.com/servers/eserver/serverproven/compat/us/. For more
information, see the Installation and User’s Guide.
If an optional BladeCenter Storage Expansion Unit 3 is installed, you can use it to
control all of the SAS hard disk drives installed in the blade server. Yo u enable this
feature using the Configuration/Setup Utility program (see the Installation and
User’s Guide for information and instructions).
Important: Yo u must create the RAID array before you install the operating system
on the blade server.
You can use the LSI Logic Configuration Utility program to configure the SAS hard
disk drives and SAS controller. To start the LSI Logic Configuration Utility, complete
the following steps:
1. Turn on the blade server (make sure that the blade server is the owner of the
keyboard, video, and mouse) and watch the monitor screen.
2. When the message
Press Ctrl-C to start LSI Logic Configuration Utility
appears, press F1. If an administrator password has been set, you must type
the administrator password to access the full LSI Logic Configuration Utility
menu.
3. Follow the instructions on the screen to modify the SAS hard disk drive and
SAS controller settings.
