MAINTENANCE INTRODUCTION
Fan and Filter Maintenance
This section explains how to remove one of 15 Fans and replace the Filter on your
Net-Net 6300.
Remove and Install
Individual Fans
The individual fan is a user-serviceable, hot-plugable component. There are 15
individual Fans in the Net- Net 6300. If the Net-Net 6300 experiences a Fan
malfunction you must remove the existing Fan and replace it with a functional one.
The hot-plugable 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 Net-Net 6300 Air Filter is built into the Bezel and is not a Field Replaceable Unit.
Caution 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 individual fans:
1. Press two fingers against the left end of the plastic Fan Bezel and pull directly
toward you. There are 4 posts that hold the Bezel in place.
