Hi every body!
I have few questions:
Let me quote from my cisco press book:
" If one power supply fails in combined mode, the switch powers down some of its modules until the required power load can be met by one functioning power supply."
How does switch determine which module's power be turned off first?
How can we determine which power supply is suppling power to modules in switch.Is it power supply #1 or #2?
thanks a lot!
How about some graphical images? :)
You are indeed correct and I should amend my last sentence, my last sentence is only true in combined mode, not redundant - my apologies - long day :(
According to the link I posted on the 4500:
Redundant mode-Redundant mode uses one power supply as a primary power supply and the second power supply as a back-up. If the primary power supply fails, the second power supply immediately supports the switch without any disruption in the network. Both power supplies must be the same wattage. A single power supply must have enough power to support the switch configuration.
