| Product Description |
Cisco PWR-4320-AC Full English Description
Product Overview
The Cisco PWR-4320-AC is an external 108W AC power adapter (spare power supply) designed exclusively for the Cisco ISR 4321 Integrated Services Router (ISR4321, ISR 4320 series). It delivers stable regulated +12VDC power to the router mainboard, routing processors, and installed NIM interface modules. This standard non-PoE power unit is the factory default power supply for basic branch office deployments without PoE requirements. It adopts a desktop external brick form factor with a dedicated 4-pin proprietary output connector for connection to the ISR4321 router.
Key Features
-
108 Watt Continuous Rated Output
Output specification: 12VDC / 9A. Provides sufficient power for standard ISR4321 configurations with basic network modules.
Note: This modeldoes not support PoE. Deployments requiring PoE/PoE+ must selectPWR-4320-POE-AC.
-
Universal Wide-Range Global AC Input
Worldwide auto-ranging AC specification:
-
Input Voltage: 100 VAC ~ 240 VAC
-
Operating Frequency: 47 Hz – 63 Hz
-
Standard IEC C14 inlet for AC mains cord connection
-
External Desktop Brick Form Factor
External power supply design, separate from router chassis. No internal hot-swap capability. The proprietary 4-pin DC cable connects directly to the rear power port of ISR4321.
Important Note: Only compatible with ISR4321. Not supported on ISR4331, ISR4351, ISR4221 or other ISR 4000 family routers.
-
Plug-and-Play Deployment
Simple installation with no configuration required. Suitable as factory replacement spare unit (PWR-4320-AC=).
-
Built-in Hardware Protection Circuitry
Integrated overvoltage protection (OVP), overcurrent protection (OCP), over-temperature protection (OTP), and short-circuit protection to protect the power supply and ISR4321 router hardware.
-
Energy Efficient Design
Meets global power efficiency standards, low idle power consumption, supporting stable 24/7 continuous operation for enterprise branch networking.
Supported Hardware Platforms
-
Cisco ISR 4321 Integrated Services Router (ISR4321)
Incompatible: ISR4221, ISR4331, ISR4351, ISR4400 series and all other Cisco ISR platforms.
Typical Application Scenarios
-
Enterprise branch office WAN gateway deployments without PoE access point powering
-
Small-to-medium business multiservice routing (VPN, firewall, basic SD-WAN)
-
Remote site data center interconnection
-
Replacement spare power supply for existing ISR4321 installations
-
Network environments without requirement for IEEE802.3af/at PoE functionality
Technical Specifications
-
Form Factor: External desktop AC-DC power brick
-
Input Type: Universal 100–240VAC wide-range AC
-
Output: 12 VDC, 9A (108W)
-
DC Connector: Proprietary 4-pin plug
-
Hot Swappable: No (external fixed adapter)
-
PoE Support:Disabled
-
Compliance: UL, CE, FCC Class A, RoHS certified
