Server Access
Removing the Host Module
Use the procedure in the preceding section, “Accessing the Host Module,” 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 16 kg (35 lb). Remove both
processor boards or all of the memory cartridges before handling the module,
or have at least 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.
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. Disconnect all of the cables connected to the I/O expansion boards.
3. Disconnect the cable management harness from the back of the server. Clips at
three points connect it, one at the server (harness clip 1) and both the left and
right cable reels (harness clips 3 and 4). Refer to Chapter 6 for more information.
4. 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.
