Cisco PWR-IPPHONE-30W Full English Description

Product Overview

Important Note: This is an external standalone power brick,not an internal hot-swappable chassis PSU. The connected IP phone must be fully powered down before replacing the adapter. Verify DC plug specification, wiring polarity before installation; mismatched connectors may cause permanent hardware damage. Non-certified third-party adapters are not recommended and may void Cisco endpoint warranty.

Key Features

1. 30 Watt Continuous Rated Output

   DC Output: 48 VDC, supporting power supply for high-end Cisco IP Phones including models with attached expansion modules. Provides stable, clean regulated DC power under full operating load for voice communications endpoints.
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 interchangeable region-specific AC power cords (US / EU / UK / AU).

1. Desktop Brick Form Factor

   Compact external AC-DC power unit with fixed DC output cable and proprietary barrel connector designed exclusively for compatible Cisco IP phones.

   Important Note: Not interchangeable with power adapters of different voltage ratings (12V/24V) or lower wattage IP phone power cubes.
2. Non Hot-Swap Design

   Live disconnection is unsupported. Complete power shutdown of the IP phone endpoint is mandatory during adapter replacement.
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 IP telephony equipment.
4. High-Efficiency Energy Saving Design

   Low standby idle power consumption, compliant with international energy efficiency standards. Optimized for 24/7 continuous operation in office unified communications environments.

Supported Hardware Platforms

• Cisco IP Phone 7800, 8800 Series
• Cisco Unified IP Phone 6900, 7900 Series
• Desktop VoIP telephony endpoints requiring external 48V local power without PoE
