Installing an Extreme Networks AC PSU

2For the AC power cord:

●If you are replacing only the power supply and you will use the existing AC power cord for the new PSU, you do not need to unplug the AC power cord.

●If you are removing and replacing an AC power cord:

■Remove the power cord retaining bracket as described in “Disconnecting a BlackDiamond 8810 AC Power Cord” on page 127 or “Removing the BlackDiamond 8806 AC Power Cord Retainer Channel” on page 130.

■Completely disconnect and remove the old power cord.

■Connect the new 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.

3Lift the handle on the PSU.

4Pull the handle of the PSU to disconnect the PSU from the power connector at the back of the power supply bay. Slide the PSU partway out of the bay.

5Wearing thermal protective gloves, place both hands underneath the PSU to support the weight as it is pulled out from the switch.

6To install a replacement PSU, follow the steps under “Installing the PSU” on page 91.

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.
