OK, combining suggestions from above:

1. Current BIOS version.
2. Current Firmware version
3. Manger Password (hardened)
4. Operator Pasword (hardened)
5. Change Public community to match network SNMP community
6. Password protect SNMP communities

Hmmm ... well, this should be a good start.

OOpsie!

7. Document versions, configuration and settings.
