Description

The ASR9K-DC-PEM-V2 is a DC Power Entry Module for the Cisco ASR 9000 Series modular chassis. It brings -48V DC feeds into the router and houses the 2.1 kW DC power supplies (PWR-2KW-DC-V2). It suits service provider and carrier-grade edge and core deployments, such as carrier Ethernet, mobile backhaul and MSE, typically in telco central offices that run -48V DC plant.

The module accepts a DC input range of -40 to -72V (-48V nominal), rated 50A nominal and 60A maximum. It supports A/B feed redundancy and N+1 DC redundancy, with a fully load-sharing power infrastructure and no power zone restrictions. Power module airflow is front-to-back. As part of the pay-as-you-grow power architecture, capacity can be added as line cards are added, which reduces initial capital outlay. The number of PEMs per chassis varies: one in the ASR 9006 and ASR 9904, two in the ASR 9010, three in the ASR 9912 and four in the ASR 9922. No licence or subscription is required for the PEM itself.

The V2 DC PEM is shared across the ASR 9006, ASR 9010, ASR 9904, ASR 9912 and ASR 9922 chassis. AC and DC modules cannot be mixed in the same chassis, so it should be paired with other DC power components. The spare part number is A9K-DC-PEM-V2=.
