Cisco PWR-24V-3A Full English Description

Product Overview

Important Note: This is an external standalone power brick,not a hot-swappable internal chassis PSU. The connected host appliance must be fully powered down for adapter replacement. This unit only supplies system operating power anddoes not support PoE output. Always verify DC plug dimensions, pinout and polarity before installation; mismatched connectors may permanently damage equipment. Third-party uncertified adapters are not recommended and may void hardware warranty.

Key Features

1. 72 Watt Continuous Rated Output

   DC Output: 24 VDC, maximum 3A. Delivers stable, regulated power for supported Cisco network hardware under full operating load.
2. Universal Wide-Range Global AC Input

   Worldwide auto-ranging mains specification:

• Input Voltage: 100 VAC ~ 240 VAC
• Operating Frequency: 50 Hz – 60 Hz
  Compatible with regional AC power cords (US / EU / UK / AU plug variants available).

1. Desktop Brick Form Factor

   Compact external AC-DC power unit with fixed DC output cable and dedicated barrel connector for supported Cisco hardware.

   Important Note: Not interchangeable with adapters of different voltage (12V/48V) or lower current ratings.
2. Non Hot-Swap Design

   Live disconnection is unsupported. Complete power shutdown of the target network appliance is mandatory to replace the power adapter.
3. Multi-Stage Built-In Hardware Protection

   Integrated overvoltage protection (OVP), overcurrent protection (OCP), short-circuit protection (SCP), overtemperature protection (OTP), and surge protection to safeguard both the power adapter and connected Cisco equipment.
4. High-Efficiency Energy Saving Design

   Low standby idle power consumption, compliant with international energy efficiency standards. Designed for reliable 24/7 continuous operation at remote offices, small branches and lab environments.
