new PSU, you do not need to unplug the AC power cord.
●
If you are removing and replacing an AC power cord:
a Remove the power cord retainer as described in “Disconnecting a BlackDiamond 8810 AC Power

supply bay. Slide the PSU partway out of the bay.

Wearing thermal protective gloves, place both hands underneath the PSU to support the weight as it
is pulled out from the switch.
6 To install a replacement PSU, follow the steps under “Installing the PSU” on page 101 .
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.
