4 Secure the Extreme Networks 600/900 W AC PSU into the power supply bay by pushing down on
the locking handle until it clicks in place.

If you are just replacing a power supply, you do not need to unplug the AC power cord.
● If you are installing a new power supply into a previously unused slot on a switch with a
retaining bracket, remove the power cord retaining bracket as described in Chapter
2, “BlackDiamond AC Power Cord Retaining Brackets.” Connect the AC power cord to the AC
input on the front of the switch and then connect the opposite end of the AC power cord to the
wall outlet. After the cord is connected, re-install the power cord retaining bracket.
● If you are installing the power supply on a switch that does not have a power cord retaining
bracket, connect the AC power cord to the AC input on the front of the switch and then connect
the opposite end of the AC power cord to the wall outlet. After the cord is connected, install the
power cord retaining bracket as described in Chapter 2, “BlackDiamond AC Power Cord
Retaining Brackets.”
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.
To install additional Extreme Networks 600/900 W AC PSUs, repeat steps 1 through 5.
