Introduction
The Cisco 6160 chassis is equipped with one or two -48VDC PEMs, which distribute direct current (DC)
power within the chassis. The Cisco 6160 needs only one active PEM to operate; if two PEMs are
installed, a secondary PEM serves as a hot backup to the first PEM.
Each PEM should be connected to a single DC power source. For full power redundancy, two PEMs must
be installed and connected to two separate DC power sources.
