Hot-Swapping Power Supplies

Hot swapping is supported on models with redundant power supplies. In order to support the hot swap-
ping of power supplies, the switch must have:
An operational redundant power supply
•
Note. Hot swapping power supplies on switches without redundant system power will result in system
power interruption and a loss of network connectivity.
To hot swap power supplies, follow the steps below:
1
Begin by locating the power supply to be swapped, then disconnect the power cord from its power
source. The system will remain operational.
2
Remove the two screws located at the top of the power cord retainer bracket. Set the retainer clip and
screws aside; they will need to be reinstalled later.
3 Unplug the power cord from the power supply.
4
Next, remove the attachment screws used to secure the power supply retaining strap to the power
supply tray. Set the screws aside; they will need to be reinstalled later.
5
Carefully remove the retaining strap from the power supply tray. Be careful not to disrupt the
operational power supply adjacent to the power supply being hot swapped.
6
Lift the power supply that is being hot swapped out of the power supply tray and unplug its connector
cable from the power supply port located in the back of the switch chassis.
7 Install the new power supply by following the installation steps beginning at step 3 on
chapter.
