Description

The PSU2KW-DCPE is a 2000W DC power module for the Cisco 8000 Series, built for service provider and carrier sites such as central offices and telco facilities that run a 48V DC feed. It is a field-replaceable module designed for the Cisco 8711-32FH-M and 8712-MOD-M fixed routers, which are used for business edge, residential aggregation, 5G mobile backhaul, provider core and internet peering.

The module provides 2000W of DC output capacity with a dual-feed input accepting a nominal -48 to -60V DC range at 55A. Airflow is port-side exhaust, also called back-to-front, so it must be paired with port-side-exhaust fan modules such as FAN-1RU-PE-V2 or FAN-PE-V3. Each DC input should be protected by a 60A DC-rated circuit breaker on the 8711-32FH-M and 8712-MOD-M, and it connects using power cable PWR-2KW-DC-CBL.

The chassis has two PSU slots for 1+1 redundancy. AC and DC supplies cannot be mixed, and port-side-intake and port-side-exhaust configurations cannot be mixed. The 8711-48Z-M and 8711-28H8F-M use the 1.2KW DC supplies instead. No licence is required for the power module itself.

Enquire with XS Network Tech for new or used pricing and availability.

FAQs

Q: Does this power supply need a licence?
A: No. The power module itself needs no licence or subscription. The host router runs Cisco IOS XR under the Flexible Consumption Model.

Q: What DC input and circuit protection does it need?
A: It takes a dual-feed -48 to -60V DC input at 55A. On the 8711-32FH-M and 8712-MOD-M, each DC input should be protected by a 60A DC-rated circuit breaker, and it connects with cable PWR-2KW-DC-CBL.

Q: Which chassis and fan modules is it compatible with?
A: It is designed for the Cisco 8711-32FH-M and 8712-MOD-M. It must be paired with port-side-exhaust fan modules such as FAN-1RU-PE-V2 or FAN-PE-V3.

Q: How does it differ from PSU2KW-DCPI?
A: PSU2KW-DCPE exhausts air at the port side (back-to-front), while PSU2KW-DCPI is the port-side-intake variant. The two cannot be mixed in the same chassis.

Q: Can I mix it with AC power supplies?
A: No. AC and DC supplies cannot be mixed in one chassis, and the airflow direction of the supplies and fan modules must match.
