1. Locate the power cables on the faulty switch.
2. Label and unplug the power cables after the switch reboots.
3. Label and unplug all the cables from the faulty switch and secure them to prevent damage during switch
replacement.
4. Remove the switch from the rack.
5. Install the replacement switch in the rack.
6. Connect the power cables and management port cables.
The switch automatically powers on when AC power is applied. There is no power
button. It might take up to five minutes for the System Status LED to turn green.
7. Connect to the switch using the RJ-45 management port or the Serial Terminal Interface.
Verify the operating system version on the switch
Verify the OS software version on the switch. The version on the faulty switch and the healthy switch should
match.
