Cisco IGX-PEM-BC PEM Back Card is a DC back card for Cisco IGX 8420 and IGX 8430 switches, designed to host two IGX-PEM modules. It provides the DC back-end interface inside the IGX chassis, enabling a two-PEM configuration for the system’s power architecture. Compatible with IGX 8420 and IGX 8430 platforms, this back card is used to support two PEMs that feed DC power to the enclosure.
