This section explains how to remove and replace the fan module and filter on your
Acme Packet 4500.
The fan module is a user-serviceable, hot-swappable component. If the Acme Packet
4500 experiences a fan module malfunction, you must remove the existing fan
module and replace it with a functional one.
The hot-swappable fan module removal and replacement procedures require that
you have a replacement fan module on hand. In order to maintain system
operations, you must be able to remove the malfunctioning fan module and quickly
replace it with a functioning one to prevent the system from overheating.
An over temperature condition can stop packet processing.
If you do not have a replacement fan module nearby, always shut down the system
and disconnect the power before removing the malfunctioning fan module to
replace at a later time.
When removing and replacing a fan module, remember to first ground yourself
using appropriate ESD grounding equipment such as a wrist or heel strap.
