Removing an Extreme Networks 325 W AC PSU
CAUTION
An operating 325 W AC PSU may be hot to the touch; use thermal protective gloves when handling the 325 W AC
PSU during removal.
CAUTION
To disconnect the system power, disconnect ALL power supply units. Disconnect the power cord before you remove
the PSU from the chassis.
To remove an Extreme Networks 325 W AC PSU:
1 Attach an ESD-preventive wrist strap to your wrist and connect the metal end to the ground
receptacle on the top right corner of the switch front panel.
2 Disconnect the AC power cord from the wall outlet.
3 Loosen the middle screw on the power cord bracket to allow removal of the power cord. After the
screws are loosened, disconnect the AC power cord from the AC input on the front of the PSU.
4 Loosen the two captive screws that secure the PSU front panel to the chassis frame.
5 Use the handle to slide the PSU out of the chassis.
NOTE
Leave the ESD strap permanently connected to the switch, so that the strap is always available when you need to
handle ESD-sensitive components.
