Replace The Fan - Cisco GoQAM Installation And Operation Manual

Chapter 7 Inspect the Modulator

Replace the Fan

The GoQAM modulator has three dual fan units on the side panel. Each of these
units contains two fan rotors. You must replace the entire dual fan unit if one of the
fan rotors should fail. The fan units are designed to be "hot swappable," meaning
that you do not necessarily have to power down the GoQAM to replace a fan unit
that has failed.
Important! In order to hot swap a dual fan unit, you must have the following:
Sufficient length in all cords and cables so you can slide the device forward in the

rack far enough to fully access the dual fan units on the side panel.
The ability to externally support the GoQAM with a cart or table or with the

assistance of another person.
Note: If you do not have sufficient length in all cords and cables, you will have to
power off the unit, disconnect all cords and cables, and completely remove the
GoQAM from the rack to replace a dual fan unit that has failed.
Important! If a fan fails or is failing, contact Cisco Services to obtain a replacement
fan.
Notes:
The part number for the replacement fan unit is 4003088.

The part number for the kit that includes the replacement fan and instruction

sheet is 4007620-40.
This section provides the procedure for replacing a dual fan unit on the GoQAM by
either hot swapping the fan unit, or by powering off, disconnecting, and removing
the GoQAM completely from the rack.
When Can I Perform This Procedure?
If you cannot hot swap the dual fan unit, you need to replace the fan unit during a
maintenance window. This is necessary because you will have to power off and
disconnect the GoQAM to replace the fan unit, thereby temporarily disrupting all
broadcast services configured and provisioned on this GoQAM.
Important! Schedule the maintenance window to replace the fan as soon as possible
to avoid damage to the GoQAM.
