Host Module Removal and Replacement Procedures
Host Module
The host module is located at the rear of the server. Remove it to replace or service
non-hot-plug components or to access other components in the host module.
IMPORTANT: You must re-enter the server serial number through RBSU after you replace the host
module. Refer to the “Re-entering the Server Serial Number” section in Chapter 2.
Removing the Host Module
Use the appropriate procedures in this chapter to install or replace hot-plug fans or
PCI/PCI-X Hot Plug expansion boards. To replace or service non-hot-plug components or
address problems in the host module, remove the module from the chassis.
WARNING: The host module weighs more than 15.88 kg (35 lbs). HP recommends either
removing both processor boards or all of the memory cartridges before handling the
module, or having two people handle the module together.
CAUTION: Do not attempt to remove the host module while power is applied to the system.
The host module is not hot-pluggable. Immediate system shutdown and data loss will occur.
To remove the host module from the chassis:
1. If the computer is on, place the computer in Standby mode and disconnect the power
cords. Refer to Chapter 7 for more information.
2. If you are replacing an item, it might be necessary to remove all of the cables connected
to the I/O expansion boards. Disconnect the cable management system harness from the
server. Refer to Chapter 3.
3. Open the top access panels to gain access to the host module and the processor boards.
HP recommends removing the processor boards to lighten the module.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the internal
system components to cool before touching them.
