Cisco Core Power Supply Upgrade !

changing a core power supply , first thought YES i need downtime ! and how long it will take to reboot …

intrest part is no need for downtime , if Cisco power set to HA . then ….

just swap one by one with no effect hopefully …( remove old one put new one and power it up , give few min to verify , then same to the other power supply )

First time to know that, and to try it live !



add to that this even works fine for downgrading power supply .. tested
