Removing and Replacing the Fan Assembly Module
Replacing the Fan Assembly Cable
This procedure is applicable to both the fan modules (UBR10-FAN-ASSY= and
UBR10012-FAN-PLUS=).
Prerequisites
Replacing a fan cable requires removing the cooling facilities of the chassis. It is not necessary to remove
power from the chassis for this procedure. However, because you are shutting down the fans that cool
the chassis and boards, it is important to have the new cable ready for immediate installation.
Required Tools and Equipment
Replacement fan cable (UBR10-FAN-CAB=)
Steps
Verify which connector goes in the bracket in the back of the chassis and which connector goes into the
Step 1
front connector.
Bend the cable in a "U" shape at both ends, to facilitate getting the cable into the rear bracket. (See
Step 2
Figure
Tip
Step 3
Install the cable in the rear bracket.
Step 4
Make sure that the cable lays flat on the enclosure bottom so as not to restrict the movement of the fan
assembly cable as it is pushed back into the chassis.
Connect the cable with the front connector.
Step 5
Step 6
Ensure that you secure the cable using the tie wrap exactly as the previous cable was secured and route
the cable inside the fan assembly module.
Slide the fan assembly module back into the chassis. The module should slide smoothly back into the
Step 7
chassis without interference with the cable.

Use the existing cable as a template.
If the fan assembly module does not slide easily into the chassis, remove the module and check
the location of the cable. The cable should lay flat along the bottom of the fan assembly
enclosure.
