Power Supply Module
Power Supply Module Overview
Applicable model numbers:
• C9400-PWR-3200AC and spare C9400-PWR-3200AC=
• C9400-PWR-2100AC and spare C9400-PWR-2100AC=
Unless otherwise indicated, power supply information in this document applies to all available power supply
modules.
Note
The chassis supports one to eight field-replaceable, AC-input power supply modules, each with its own on/
off rocker switch.
Features
• Self-cooling, with a minimum airflow of 17 cubic feet per minute (CFM) at 100 percent load.
• Provides a regulated 55 VDC PoE compliant main output and 3.3 VDC standby output.
• Supports only single-phase source AC. Source AC can be out of phase between multiple power supplies
or multiple AC-power plugs on the same power supply because all AC power supply inputs are isolated
• Has a release latch and cord-retention mechanism on the front panel of the module, to avoid accidental
removal of the module or the attached power cord.
• Supports redundant and combined configuration modes. A single (non-redundant) or a dual (redundant)
power supply configuration, can support the following loads:
Output Power with
C9400-PWR-2100AC
Output Power with
C9400-PWR-3200AC (In Watts)
Input Voltage (VAC)
2112W3200W200VAC
950W1570W100VAC
• Has a built-in, front-facing, passive RFID tag that uses Ultra High Frequency (UHF) RFID technology
and requires an RFID reader with compatible software. It provides auto-identification capabilities for
asset management and tracking. The RFID tags are compatible with the Generation 2 GS1 EPC Global
Standard and are ISO 18000-6C compliant. They operate in the 860- to 960-MHz UHF band. For more
information, see Radio Frequency Identification (RFID) on Cisco Catalyst 9000 Family Switches.
