Cisco PWR-12V-5A Full English Description

Product Overview

Important Note: This is an external standalone power brick,not a hot-swappable internal chassis PSU. Host equipment must be fully powered down to replace the adapter. This unit supplies only basic system power and doesnot support PoE output. Connector polarity and plug dimension must match the target Cisco hardware strictly; mismatched connectors will cause device malfunction or permanent damage.

Key Features

1. 60 Watt Continuous Rated Output

   Output specification: 12 VDC, maximum 5 Amps. Provides sufficient stable power for compatible Cisco branch routers and security appliances under full 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
  Comes with region-specific AC power cords (US/EU/UK/AU plug options).

1. Desktop Brick Form Factor

   Compact external AC-DC power unit with dedicated DC output cable and proprietary barrel/4-pin connector for supported Cisco hardware.

   Important Note: Not interchangeable with adapters of different voltage or current ratings. Third-party non-certified adapters are not recommended and may void Cisco hardware warranty.
2. Non Hot-Swap Design

   The connected network appliance requires complete power shutdown before adapter replacement. Live disconnection is not supported.
3. Integrated Multi-Stage Hardware Protection

   Built-in 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 network equipment.
4. High Efficiency Design

   Low standby idle power consumption, complying with international energy efficiency standards, supporting reliable 24/7 continuous operation for remote office and small branch network deployments.
