Stack Redundancy
In the unlikely event that a P330 switch or Octaplane link should fail, stack integrity 
is maintained if the redundant cable is connected to the stack. 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. You can remove or replace any unit within the stack without disrupting 
operation or performing stack-level reconfiguration. 
Since each P330 module has an integral SNMP agent, any module in a stack can 
serve as the stack Network Managment Agent (NMA) while other NMAs act as 
redundant agents in “hot” standby. If the “live” NMA fails then a backup is 
activated instantaneously.
