a If necessary, remove the power cord retaining bracket as described in Chapter 3, “BlackDiamond AC Power Cord Retaining Brackets.”

b Connect the new AC power cord to the AC input on the front of the switch and to the wall outlet on the other end. Then re-install the power cord retaining bracket.

c Re-install the power cord retaining bracket as described in Chapter 3, “BlackDiamond AC Power Cord Retaining Brackets.”

To install additional Extreme Networks AC PSUs, repeat steps 2 through 5.

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.
