Power supply Cisco PWR-C2-250WAC-RFB 250W AC for compatible Cisco devices

Cisco PWR-C2-250WAC-RFB is a 250W AC power supply module designed for compatible Cisco devices. This single-output AC unit provides 250 watts of continuous power intended to replace or supplement existing power modules in supported switches and network appliances. The module restores or adds reliable AC power to systems that accept the PWR-C2-250WAC-RFB form factor, enabling maintenance without extended downtime and maintaining normal device operation.

Advantages

The Cisco PWR-C2-250WAC-RFB offers a compact design and standardized connector interface for straightforward installation and replacement. With a 250W rating, it supplies sufficient power for many mid-range switches and network appliances that require factory-compatible AC modules. The unit supports hot-swap replacement in devices that permit it, reducing service interruption. Built to Cisco compatibility specifications, the module helps ensure electrical and operational compatibility with supported hardware.

Suitable for

• Replacing a failed AC power module in compatible Cisco switches
• Adding redundancy or additional AC power capacity to network appliances
• Field service and maintenance where a like-for-like Cisco-compatible 250W AC module is required
• Lab and staging environments that use Cisco hardware with the PWR-C2 form factor

How to use

Before installation, power down the device when the platform requires shutdown for safe module replacement; if the host supports hot-swap, follow vendor instructions for live replacement. Remove the existing module according to the device service manual and insert the PWR-C2-250WAC-RFB into the designated power bay until it seats securely. Connect the AC mains cable to the module and verify that the device recognizes the new power supply via status LEDs or management interface. Confirm output voltage and operational status per the host device documentation.

Usage recommendations

Use original or factory-compatible Cisco power modules to maintain electrical compatibility. Verify device compatibility with model PWR-C2-250WAC-RFB before purchase, observe ESD precautions during handling, and follow the host device’s installation and safety procedures. Keep spare modules in inventory for rapid replacement to minimize network downtime.
