Chapter 1 Overview
If you wish to save configuration definitions, perform the following procedure:
1 Power down the switch.
2 Remove the expansion module.
3 Insert the new module.
4 Power up the switch.

Backup Power Supply

Each P330 module comes with a Backup Power Supply (BUPS) connector. If the
internal power supply fails, the P330 BUPS (available separately) automatically
supplies power to the switch for uninterrupted operation.

Fans

The P330 module fans have integrated sensors which provide advance warnings of
fan failure via management.

Network Management Agent (NMA) Redundancy

Since each P330 module has an integral SNMP agent, any module in a stack can
serve as the stack NMA while other NMAs act as redundant agents in "hot"
standby. If the "live" NMA fails then a backup is activated instantaneously.

Software Download

P330 includes a safe software download procedure in which backup code is always
present.
You should perform a reset after downloading software to the Module.
