We're planning to upgrade 5548UP to new version. Currently it's 6.0(2)N2(4). I know i need to to make three upgrade path steps to do it correctly:

I see sometimes on upgrade process we're getting this default message:

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.
Use command 'reload power-cycle'
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.
SUCCESS

My question about that warning is about "SWITCH OFF THE POWER" meaning - isn't it would be enough to do reload power-cycle ? Would i really need to go into the DC and make a physical reload ? Thanks

Also, i google a message "Once you've upgraded to either NX-OS version 4.2(1)N1(1) or 5.0(2)N1(1) and above, and completed the power cycle, then the power sequencer will be the correct level. Any subsequent NX-OS upgrades will not require the power cycle." which says that if my version is already newer than 5.0(2)N1(1) i would not need to do a power cycle for power sequence update.

On the other hand i see the old log which had updated the power sequencer:

But as i understand from 5.x version the upgrade of power seq doesnt require physical reboot.

Do i'm right ? Thanks
