Installing and Connecting Summit Power Supplies
Disconnecting a Power Cable with an Installed Cable Retaining
Bracket
If a power cable retaining bracket is installed, you must loosen the retaining bracket from the cable
before you can disconnect the power cable.
To disconnect a power cable when a cable retaining bracket is installed:
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.
3 Loosen the retaining bracket screw to allow the power connector to slide out of the bracket (see
Figure 71).
4 Disconnect the power cable from the power supply.
If you are installing a replacement power cable, tighten the power cable retaining bracket around the
new cable (see Figure 71).
If you are installing a replacement power supply, follow the instructions in “Installing and Removing
the Internal 600 Watt AC Power Supply (15412)” on page 121 or “Installing and Removing Summit48si
AC Power Supplies” on page 127. After you install the replacement power supply, install a power cable
retaining bracket as described in “Installing the AC Power Cable Retaining Bracket” on page 129.
Installing the Summit48si Switch DC Power Supply
The Summit48si switch comes with one DC power supply that is preinstalled at the factory. You can
add a second power supply for redundancy.
This section describes the steps to install the Summit38si DC power supply.
Figure 73 shows the Summit48si DC power supply.

The Summit48si DC power supplies slide in from the rear of the switch. The front of the power supply
provides a handle for inserting and removing the power supply from the chassis.
