Changing Fan Assemblies
In some circumstances, you can change a faulty fan assembly without the assistance of
a service representative. You can do this only if:
v
You are authorized by your organization to do this.
v
You have a correct spare fan assembly.
Note: Fan-and-power-supply assemblies that can be installed in 7133 Model 010,
020, 500, or 600 units cannot be installed in 7133 Model D40 or T40 units.
Attention: Do not remove two fan assemblies from the subsystem at the same time.
You do not need to remove power from the 7133 unit when changing a fan assembly.
Before Changing a Fan Assembly
1. Perform the actions described in “Starting to Deal with Problems” on page 35.
2. If you have run diagnostics and obtained a Service Reference Number (SRN) and it
is in the following list, it means that a fan assembly has a fault that can be corrected
by exchanging the fan assembly for a new one:
SRN
Component
Fan position
80231
FAN1
Left (Top in a T40)
80232
FAN2
Middle
80233
FAN3
Right (Bottom in a T40)
If the SRN is not in the list, do not change the fan assembly: call your service
representative and report the problem.
