Key Features of the AC-Input Power Supply

  • Self-Cooling Fan:
  • C9400-PWR-2100AC/3200AC: ≥7 CFM at full load
  • C9400-PWR-3200ACT: 19.87 CFM at full load (single fan)
  • Regulated DC Outputs: 55 VDC PoE-compliant main output; 3.3 VDC standby whenever AC is present
  • Single-Phase AC Support: Accepts 100–240 VAC (phases may vary across modules or cords due to input isolation)
  • Front-Panel Safety: Release-latch and cord-retention to prevent accidental module or cord removal
  • Redundancy Modes: Configurable as single (non-redundant) or dual (redundant); combined output power:
  • 200–240 VAC → 3200 W (3200ACT) / 2112 W (2100AC)
  • 100–120 VAC → 1570 W (3200ACT) / 950 W (2100AC)
  • Built-In RFID Tag: Front-facing, passive UHF tag for asset tracking (requires compatible RFID reader/software)

    Questions & Answers

    • What diagnostics work if the 2100W AC PSU won’t boot?

      Confirm the AC cord is connected, the power outlet works, and check the PSU’s LED indicators. Try reseating or swapping with a known good unit.

    • Which plug options come with the 2100W AC model?

      A country-specific AC power cord, mounting screws, and installation hardware are included in the shipment.

    • How does the 2100W AC compare to the 3200W AC supply?

      The 3200W supports higher total load, making it suitable for more UPOE devices, while the 2100W is used for lighter deployments.

    • Is there a compact AC power supply alternative for the 9400?

      Yes, 1600W and 1050W AC power supplies are available for lower-density applications.

    • What mounting kits fit the 2100W AC in a C9400 chassis?

      Standard EIA rack-mount brackets and screws, provided in the accessory kit, secure the PSU in place.

    • Which LED patterns indicate a 2100W AC fault?

      Amber or red PSU LED means a fault; green is normal operation. Rapid blinking may signal a transient error.

    • How can I hot-swap the 2100W AC hot-in-lane?

      If another PSU is online and healthy, pull out the faulty unit and slide in the replacement without needing to shut down the chassis.

    • What voltage and current specs does the 2100W AC require?

      Input: 200–240V AC, 50/60Hz, 12A. Always check your PSU label to confirm.

    • Which isolation transformers safeguard the 2100W AC?

      Use an isolation transformer rated at 2.5 kVA or greater for full protection and electrical safety.

    • How to confirm the AC-2100 module’s software support?

      Check hardware support in Cisco's official IOS XE compatibility matrix before upgrading or swapping units.

    • Can third-party PSUs substitute for the 2100W AC?

      No, only Cisco certified PSUs are supported to ensure system safety and warranty compliance.

    • What spare parts bag ships with the 2100W AC?

      Includes mounting screws, AC power cable, and sometimes a spare connector.

    • How do I silence the 2100W AC’s fault buzzer?

      Fix the source of the fault, reseat the PSU, or power cycle if necessary. Buzzer will stop once the issue is resolved.

    • What routine tests ensure 2100W AC longevity?

      Regularly test redundancy, inspect for dust, and check for secure electrical connections.

    • Does the AC-2100 support parallel supply modes?

      Yes, it can operate with another PSU in either redundant or combined power modes.

    • Which CLI outputs AC-2100 diagnostics?

      Use 'show environment power' and 'show logging' for PSU health and event information.
