Cajun P333T User’s Guide 3
Stack Redundancy
In the unlikely event that a Cajun P330 switch or Octaplane link should fail, stack
integrity is maintained. The broken link is bypassed and data transmission
continues uninterrupted. The single management IP address for the stack is also
preserved for uninterrupted management and monitoring.
Hot-Swappable
You can remove or replace any unit within the stack without disrupting operation
or performing stack-level reconfiguration. You can therefore adapt the P330 to
your requirements on the fly and with a down-time which is second to none.
Backup Power Supply
Each Cajun P330 basic unit comes with a Backup Power Supply (BUPS) connector.
If the internal power supply should fail, the Cajun P330 BUPS (available
separately,) will automatically supply power to the switch for uninterrupted
operation.
Fans
The Cajun P330 base unit fans have integrated sensors which provide advance
warnings of fan failure via management.
Network Management Agent (NMA) Redundancy
Each of the integral NMAs in the 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 will be activated instantaneously.
Software Download
Safe S/W download procedure – backup code always present.
