Installing an AC Power Supply
To install an Extreme Networks 2400 W AC PSU:
1 Attach an ESD-preventive wrist strap to your bare wrist and connect the metal end to the ground
receptacle on the top right corner of the switch front panel.
2 At each side, completely loosen the captive retaining screws and remove the power supply retainer
from the chassis (see Figure 24).

3 If necessary, remove a blank cover from the PSU slot.
4 Verify that the PSU is right side up and the latches are open (see Figure 25).
To open the latches, push the spring-loaded catch and rotate the latches away from the front of the
PSU.
