2.7.1
Power Entry Module (PEM/DC/3K)
The device's chassis is supplied with two Power Entry Modules modules (PEM/DC/3K) to
ensure electrical input (power) redundancy. The PEM modules receive, protect, and
regulate the incoming power to the chassis, and combine the dual power feeds.
Note:
A different PEM module is used when the device implements 8410 and 6310
series blades. The PEM module implemented with the 8410 blade provides
two Ethernet ports, whereas the PEM module implemented with the 6310
blade provides a single Ethernet port (which is currently not in use).
