Installation Guide

The EPS-C2 chassis can use the following types of redundant power connectors:
• Five 2x7-pin connectors, shown in Figure 318, which connect the power supply to X440 switches.

• One 2x9-pin connector, shown in Figure 319, which connects the power supply to X250e-48p and
X450e-48p switches.
Warning
The 2x9 cable is not hot-pluggable. Do not attach a powered EPS-C2 to any switch using
the 2x9 connector.

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 the 2x7 connector.
See Figure 320.
