Five 2X7-pin connectors
These connectors are compatible with the Summit X440 series switches.
Figure 293: EPS-C2 2x7 Pin Redundant Power Cable with Connector Key Tab
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 summit x440 switch.
A switch on the front of the EPS-C2 chassis (see the figure below) selects which connector type is
active for the power system.

following to connect the redundant power cables:
1 Set the connector selection switch for either the 2X9 or 2X7 connectors.
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 (see
the Redundant Power Cord
3 Verify that the side of the connector marked TOP is facing up.
