is no need to remove the fan module prior to installation. In case this part needs
service or replacement, you can remove and replace it with a functioning one.

unpredictable problems such as:
•
Garbled output on the console display
•
Sudden crashes

Caution Failure to ground the chassis properly can result in permanent
damage to the Acme Packet 4500 and its components. Bodily
harm may also result under some circumstances.
Caution The Acme Packet 4500 does not support mixing AC and DC
power supplies in the same chassis. A mixed power
configuration is prohibited.
