As part of the N5k upgrade process, the system outputs the info below:
Module 1: Refreshing compact flash and upgrading bios/loader/bootrom/power-seq.
Warning: please do not remove or power off the module at this time.
Note: Power-seq upgrade needs a power-cycle to take into effect.
On success of power-seq upgrade, SWITCH OFF THE POWER to the system and then, power it up.
Note: Micro-controller upgrade needs a power-cycle to take into effect.
On success of micro-controller upgrade, SWITCH OFF THE POWER to the system and then, power it up.
after the switch reboot itself as part of the upgrade, I can see that the power-seq is already up on the new version in "Show version", Do you really need to cut the switch power completely and then power it back up?? that means the switch will reboot twice and which is twice the outage to the connecting device (assume they are single homed to one N5k).
I have been doing the power cycle for all my previous upgrades, but is power cycle really necessary?
