Installing an EPS-600LS External Power Module

You install one, two, or three EPS-600LS power modules (model 10913) in the EPS-C chassis (Model No.
10912) to build an external redundant power system for a Summit PoE-capable switch. A redundant
power cable shipped with the EPS-C chassis provides the connection between the external power
system and the redundant power input connector on the back of the switch.
NOTE
An AC power cord is not provided with the EPS-600LS power module. See
page 218 for information about selecting a power cord.
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 rack system before installing an EPS-600LS unit.
