Redundancy / Hot Swap

CMM Redundancy Feature Exceptions for OmniSwitch 7000/8800

• Manual invocation of failover (by user command or Primary pull) should only be done during times

when traffic loads are minimal.

• Hot standby redundancy or failover to a secondary OS7000/8800 CMM without significant loss of traf-

fic is only supported if the secondary is fully flash synchronized with the contents of the primary’s

flash.

• Hot standby redundancy or failover to a secondary module without significant loss of traffic is only

supported if all the remaining units in the stack are fully flash synchronized with the contents of the

primary’s flash.

• Failover/Redundancy is not supported when the primary and secondary CMMs are not synchronized

(i.e., unsaved configs, different images etc.). In this case, upon failover, all the NIs will reset and might

go to "down" state, and to recover, need to power down the switch and power it back up.

Hot Swap Feature Exceptions for OmniSwitch 7000/8800

• Hot swap of NIs needs to be preceded by the removal of all cables connected to the NI.

• Hot insertion of unlike modules is not supported in this release.

• The Reload NI command is not supported in this release. Please use No Power NI/Power NI as an

alternative.

• All insertions of NI modules cannot be followed by another hot swap activity until the OK2 LED on

the inserted NI blinks green.

Hot Swap Feature Exceptions for OmniSwitch 6600

• When removing modules from the stack (powering off the module and/or pulling out its stacking

cables), the loop back stacking cable must be present at all times to guarantee redundancy. If a module

is removed from the stack, rearrange the stacking cables to establish the loopback before attempting to

remove a second unit.

• When inserting a new module in the stack, the loop back has to be broken. Full redundancy is not guar-

anteed until the loop back is restored.

Hot Swap Time Limitations for OmniSwitch 7000/8800

• All removals of NI modules must have a 30 second interval before initiating another hot swap activity.

• All insertions of NI modules must have a 3 minute interval before initiating another hot swap activity.

• All hot swaps of CMM modules must have a 10 minute interval before initiating another hot swap,

reload or takeover activity.

• All takeovers must have a 10 minute interval before following with another hot swap, reload or take-

over activity.
