Chapter 7: Installing Summit External Power Supplies
Installing an EPS-C2 Chassis
Install one, two, or three Summit 750 W AC power supplies (model 10931) in the EPS-C2 chassis
(model 10936) to build an external redundant power system for one or more compatible Summit
switches. One redundant power cable is shipped with the EPS-C2 chassis to provide the connection
between the external power system and the redundant power input connector on the back of a Summit
X440 series switch. Additional redundant power cables are available from Extreme Networks.
When installing an EPS-C2 chassis at the same time as a Summit switch, install the components in the
following order:
1 Install Switch into rack.
2 Install EPS-C2 chassis into rack.
3 Install power supplies into the EPS-C2 chassis.
4 Attach redundant power cable from EPS-C2 chassis to switch.
5 Attach AC power cord to internal power supply of switch, and then plug into AC power source.
6 Install AC power cords to internal power supplies of the EPS-C2 chassis, and then plug power cords
into AC power source.
WARNING!
Be sure to attach power to components in the order listed in this section. If you attach power out of the
order listed, you can damage your equipment.
The following sections describe the specific steps for installing the EPS-C2 chassis.
