4 If you are not going to install a replacement power supply, cover the power supply bay with the
blank faceplate that was originally supplied with the switch.
Otherwise, follow the instructions in “Installing a Summit 48si AC Power Supply” on page 127to
install a new power supply.
Installing the AC Power Cable Retaining Bracket
The AC power cables for Summit switches can be attached to the power supply using power cable
retaining brackets. The retaining brackets make it less likely that a power supply cable will be
inadvertently knocked loose from a power supply.
To install a power cable retaining bracket:
1 On a Summit switch with a power switch, turn off the power supply by setting the power switch to
the OFF position.
2 Disconnect the power cable from the power source and then from the Summit switch.
3 If necessary (for example, on a Summit 1i or Summit 5i), remove the two retaining screws from the
power socket on the rear of the switch using a #2 Phillips screwdriver.
Keep the screws for future use.
4 Slide the retaining bracket over the power cable, as shown in Figure 68 or Figure 70.
If necessary, loosen the retaining bracket screw.
