The SKU:341-0238-04 is Cisco part number as the internal manufacturing part number for the PWR-3900-AC power supply module.

While "PWR-3900-AC" is the orderable product name you’ll see in listings, the 341-0238-04 (or its alternate label DCJ5952-01P) is what you will typically see printed on the physical sticker of the unit itself.

This specific part number (341-0238-04) is for system power only. It powers the router's CPU, fans, and interface cards. If you need to power IP phones or cameras via the router, you would typically need the PWR-3900-POE version instead.

Each is a 400W AC power supply module designed specifically for the Cisco 3925 and 3945 Integrated Services Routers (ISR). It will serve as the primary power source for the router and its internal modules.

• ::Redundancy: You can install a second PWR-3900-AC unit in the router's second power slot. This provides 1+1 redundancy, ensuring the router stays online even if one power supply fails.These routers support dual power supplies. If you see this part number in your router and have an empty second slot, you can add another 341-0238-04 to provide 1+1 redundancy, which prevents the router from shutting down if one power supply fails.

• ::PoE Note: If you need to support Power over Ethernet (PoE) on your router's switch modules, you typically need the PWR-3900-POE version instead. The standard AC version (this model) does not provide the extra power required for PoE endpoints like IP phones or cameras.

Common Variants

• ::PWR-3900-AC/2: A common updated version or spare part designation for the same unit.
• ::PWR-3900-DC: The DC input version for telecommunications environments (central offices).
• ::PWR-3900-POE: The version required for distributing PoE power to attached devices.
