Remove and Install Individual Fans

The individual fan is a user-serviceable, hot-pluggable component. There are 15 individual fans in the Net- Net 6300. If the Acme Packet 6300/6350 experiences a fan malfunction, you must remove the existing fan and replace it with a functional one.

The hot-pluggable 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 6300/6350 air filter is built into the front bezel and is not a FRU.

Note:

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 it 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. There are 4 posts that hold the bezel in place.
