An AC power input cord is not provided with the EPS-600LS power module. You can order an
appropriate cord from Extreme Networks or from your local supplier. The power cord must
meet the requirements listed in Power Cord Requirements for AC-Powered Switches and AC
Power Supplies on page 653.
Each EPS-C chassis is shipped with a special redundant power supply cord for connection to the
Summit switch. Make sure that the EPS-C chassis is installed in the equipment rack before installing an
EPS-600LS power module.
EPS-C2 Redundant Power System
The EPS-C2 is an external power supply system that supplies redundant power to switches.
It is a standalone unit that can be rack mounted in a regular 19-inch rack system. The EPS-C2 can be
populated with up to three 750 W PoE AC PSUs (power supply units) to provide a total redundant
power budget of up to 2040 W. The redundant power supply system can connect up to five switches to
actively provide power to all five if needed.
The EPS-C2 redundant power system consists of the EPS-C2 chassis (Model 10936) plus one, two, or
three installed 750 W AC power supplies (Model 10931).
For more information about the 750 W AC power supply including LED meanings, see Summit 750 W
AC Power Supply on page 189.
