Τροφοδοτικό Cisco PWR-C5-125WAC 125W

The Cisco PWR-C5-125WAC 125W power supply is a compact external unit designed to deliver up to 125 watts of stable DC power to compatible Cisco network switches. With an input range of 100–240 V AC and support for 50/60 Hz line frequency, the unit adapts to international mains conditions. Its two-tone grey and black enclosure and small footprint (101.6 mm × 193 mm × 40.1 mm) make it suitable for installation in constrained technical spaces while heat dissipation is specified at 426.5 BTU/h to guide ventilation planning.

Advantages

The power supply provides a consistent 125 W output that supports sustained device operation and predictable power delivery. Broad input voltage and frequency compatibility simplify deployment across regions. The compact dimensions and modest weight allow easy handling and replacement, while the listed safety and compliance certifications (CE, UL 60950-1, FCC) indicate conformity with international electrical and electromagnetic standards.

Suitable for

• Replacing or upgrading power modules for compatible Cisco network switches
• Small server rooms and network closets where space is limited
• Field service and on-site maintenance tasks requiring a reliable external PSU

How to use

Before installation, power down the target switch according to the manufacturer's shutdown procedure and disconnect mains power. Install the power supply into the designated power module slot or follow the external mounting instructions in the device manual until it seats securely. Reconnect mains power and verify the switch boots and indicates normal power status. If the switch provides status LEDs or a management interface, confirm the PSU is recognised and delivering power within expected parameters.

Recommendations

Install the unit in a well-ventilated area, allow sufficient clearance for airflow, and avoid stacking multiple heat-generating components directly above the power supply. Use compatible replacement procedures as described in the Cisco product documentation and observe local electrical safety rules when connecting to mains power.
