Removing a DC Power Supply
The DC power supply may be hot to the touch; use thermal protective gloves to handle the power supply
during removal.
To remove an Extreme Networks 1200 W DC power supply:
1 De-energize the DC circuit for the 1200 W DC power supply that will be removed.
2 Press the yellow lever on the DC power supply to the left as you lift the handle on the power supply.
3 Disconnect the cable from the front of the DC power supply by pressing down the catch (see
Figure 69) and pulling out the cable.

Always be sure that the 1200 W DC power supply does not have the input cabled connected at any time
when the DC power supply is not installed in the switch. Do not remove the DC power supply from the switch
before disconnecting the input DC cable from the power supply.
4 Pull the handle of the power supply to disconnect the power supply from the power connector at the
back of the power supply bay. Slide the power supply partway out of the bay.
5 Wearing thermal protective gloves, place both hands underneath the power supply to support the
weight as it is pulled out from the switch.
To remove additional DC power supplies, repeat steps 1 through 5.
