Supply/Fan
Module
To install a power supply/fan module, see Figure 5–1 and:
Step 1 Slowly slide the module into the chassis. Guides on the chassis
assist in properly aligning the module during insertion.
Step 2 Tighten the two screws located on the bottom front of the module.
Warning
Do not operate the CPX for more than 15 minutes without a
fan, or the power supply module may overheat.
Note
Ensure that the electrical plug on the fan snaps into the
electrical receptacle of the power supply/fan module.
Caution
Insert the module with a single, steady motion. Bouncing the
module during insertion can cause an alarm condition in the
system. Also, do not force the module into the slot.
To avoid crushing or bending the power supply pins, back the
module out, and re-insert it if it does not fully insert into the slot.
