Questions & Answers

  • What steps should I take if the 1100W AC module for C1 series fails to start?

    Check the power cord, outlet, and ensure the supply is fully seated. Inspect LEDs for error colors, reseat the unit, and consult the switch logs.

  • Is the 1100-watt power supply kit complete with all parts?

    Yes, it includes the power module, AC cable, mounting hardware, and installation instructions.

  • How does the 1100W compare with other C1 power options?

    It offers a middle ground: more capacity than 350W, less than 1900W, and is suited for medium-density deployments.

  • Are non-original modules supported for this supply?

    Only Cisco-certified power supplies are supported for safety and compatibility.

  • Which applications require a 1100W power brick?

    Ideal for midsize access switches with moderate PoE demands or as a backup in high-density networks.

  • What safety warnings apply when handling this unit?

    Disconnect all power, let the unit discharge, and use anti-static wrist straps during installation or servicing.

  • Which chassis models accept the 1100W supply?

    Many Catalyst C1 series switches are compatible—always confirm using Cisco’s official datasheet.

  • How can I check functionality after installation?

    Look for a green LED and use CLI commands like `show power` to verify the module status.

  • Is a firmware update required for this PSU?

    Not for the module itself, but keep switch firmware updated for continued hardware support.

  • What should I look for in the status LEDs?

    Amber or red means a problem—consult the manual or CLI output for specifics.

  • How often should cleaning or inspection occur?

    Quarterly in most environments; more often if there is visible dust or the site is industrial.

  • Can this model be swapped live on supported switches?

    Yes, hot-swap is possible on most compatible models.

  • How do I know if this wattage is sufficient for my setup?

    Add up the switch’s total power draw and PoE requirements; if under 1100W, this supply is adequate.

  • Where are the official installation instructions?

    Cisco’s support portal has all hardware install and configuration guides.

  • How to confirm this module is an original Cisco product?

    Check for proper part numbers, serials, Cisco branding, and use Cisco’s online authenticity checker.

  • What is the right environment for optimal performance?

    Cool, dry, dust-free, with ambient temperature between 0–40°C.

  • Can I run two modules in tandem for redundancy?

    Yes, supported C1 chassis allow a second supply for failover.

  • How to check for AC input issues with this supply?

    Use a multimeter to check voltage, inspect for cable damage, and review switch logs for power alarms.

  • What’s the process for warranty replacement?

    Contact Cisco TAC or your reseller with module serial number and purchase details.

  • Are there tools to monitor the PSU remotely?

    Yes, use SNMP, Cisco DNA Center, or CLI for real-time health and status monitoring.
