Hi

Supervisor engine 720 redundancy takeover failure

Here is the configuration,

1x 6513

1x WS-C6K-13slot

2x ws-sup720-3b

2x ws-cdc-2500W

2x ws-x6516a-gbic

2x ws-x6548-rj-45

OS image :

The sups are in redundancy mode. They are both running the following image:

S72033-pk9sv-mz.122-17d.sxb11.bin

Issue :

The redundant sup did not pick up properly

Indicates that the" boot file did not load, it stayed in ROM monitor"

1)Why did the supervisor engine fail?

2) why didn't the redundant supervisor engine pickup when the active one failed?

Please help me out to find the cause of failure in sup720 and failure in takeover. Thanks in advance
