Connecting Redundant Power Cables for the EPS-C2 Chassis

The EPS-C2 chassis can use the following types of redundant power connectors:

The redundant power cable has keyed ends. The key is a plastic tab on the cable connector housing to ensure correct alignment of the connector. The keyed ends of the 2x7 cable are not symmetrical; one end of the cable will fit into the EPS-C2 chassis and the other end will fit into the switch.

After the EPS-C2 has been installed in a rack and the power supplies have been installed, do the following to connect the redundant power cables:

  1. Set the connector selection switch, located on the front of the EPS-C2 chassis, for either the 2x9 or the 2x7 connector.
    See EPS-C2 Connector Selector Switch.

  2. Connect the keyed end (for the 2x7 connector cable, the end with the tab offset from the edge of the connector pins) of the redundant power cord to the EPS-C2 chassis.
  3. Verify that the side of the connector marked TOP is facing up.
  4. Connect the other end of the redundant power cable (for the 2x7 connector cable, the end with the key flush with the edge of the connector pins) to the Summit switch.
    See Installing the Redundant Power Cord.

    Be sure that the side of the connector marked TOP is facing up.
