Cisco N9K-PDC-3000W-B 3000W DC F-B Airflow (Port Side Intake) Power Supply

The Cisco N9K-PDC-3000W-B is a 3000W DC hot-swap power supply for the Nexus 9500 modular chassis. Cisco describes it as a port-side intake unit, so air moves front-to-back. Unlike Nexus 9300 power supplies, the -B suffix on this part does not mean back-to-front airflow.

It accepts -48 to -60 VDC nominal input across a -40 to -70 VDC range and is rated 90 percent or better efficient from 20 to 100 percent load. Installation needs four customer-supplied cables, two negative and two positive, with 6 AWG recommended. A Nexus 9504 takes up to four supplies, a 9508 up to eight, and a 9516 up to ten. Each supply can be replaced while the chassis keeps running.

The Nexus 9500 cools front-to-back only, so there is no back-to-front version of this supply. DC power is common in telecom central offices and other sites built around -48V plants.

For AC-powered chassis, see the Cisco N9K-PAC-3000W-B 3000W AC port-side intake power supply. The Cisco N9K-C9504-FAN Nexus 9504 fan tray is also available for the Nexus 9504.

The supply measures 5.25 x 17.75 x 1.75 inches and weighs 6.4 pounds.
