Removing and replacing a CPU and heat sink module
WARNING!
To reduce the risk of personal injury from hot surfaces, allow the drives and the
internal system components to cool before touching them.
CAUTION:
To prevent possible server malfunction, do not mix CPUs of different speeds or cache
sizes.
CAUTION:
Removing a CPU will cause the DIMM loading rules to change. See
“Memory
configurations” (page 34)
and use the loading rules for two CPUs. If you do not perform these
procedures, then any memory associated with the removed CPU will not be seen by the system.
Removing a CPU and heat sink module
CAUTION:
To prevent thermal instability and damage to the server, do not separate the CPU
module from the heat sink.
1.
power off the server and remove it from the rack (
“power off the server” (page 102)
and
“Remove the server from the rack” (page 102)
).
2.
Remove the access panel (
“Removing the access panel” (page 30)
).
3.
Open the CPU cage.
4.
Disconnect the power cord (see 1 below)
5.
Rotate the CPU locking handle up and back until it reaches a hard stop (see 2 below)
WARNING!
The heat sink locking lever can constitute a pinch hazard, keep your hands on
top of the lever during installation to avoid personal injury.
