Acme Packet 4600 Hardware Installation and Maintenance Guide
This section explains how to remove a fan and replace the air filter on your Acme
Packet 4600.
The individual fan is a user-serviceable, hot-swappable component. There are five
individual fans in the Acme Packet 4600. If the Acme Packet 4600 experiences a fan
malfunction, you must remove the existing fan and replace it with a functional one.
The hot-swappable fan removal and replacement procedures require that you have
a replacement fan on hand. In order to maintain system operations, you must be able
to remove the malfunctioning fan and quickly replace it with a functioning one to
prevent the system from overheating.
The Acme Packet 4600 air filter is located behind the front bezel and is a Field
Replaceable Unit (FRU).
An over temperature condition can stop packet processing.
If you do not have a replacement fan nearby, always shut down the system and
disconnect the power before removing the malfunctioning fan to replace at a later
time.
When removing and replacing a fan, remember to first ground yourself using
appropriate ESD grounding equipment such as a wrist or heel strap.
To remove a fan:
1. Press two fingers against the left end of the plastic fan bezel and pull it directly
toward you. The fan bezel comes off the chassis. Set the fan bezel aside. The
individual fans are now exposed.
