Cisco 12000/6-DC-PEM DC Power Entry Module for 12000 Series GSR Routers

Cisco 12000/6-DC-PEM DC Power Entry Module for 12000 Series GSR Routers is a power supply module for Cisco equipment.

This is a DC part. Telecoms and carrier routing equipment is predominantly minus 48 V DC, which is what allows a site’s battery string to carry the equipment through a mains interruption without any transfer delay. If the site has only AC, the AC variant is a different part number rather than a setting.

This listing carries no specification text, which is why this page describes the family rather than the exact configuration. Routers of the same model were frequently sold in several configurations differing in memory, interface cards, power supply and licensing, and those differences matter more than the model name does. We can pull the exact specification for this part number from the vendor’s own database before you order.

Three questions worth answering before any router purchase, whatever the model. What the throughput requirement actually is with your feature set enabled, rather than the datasheet figure measured without it. Whether the features you need are licensed as well as present, since on most platforms security and performance are separate entitlements. And how many slots or ports you will need in three years, because adding capacity is cheap and replacing a chassis is not.

Tell us the chassis, what is already fitted and what you intend to populate it with, and we will confirm the supply is sized for it. On a replacement, read the part number off the unit in the chassis rather than working from the original order, because power modules are among the most commonly swapped parts in a router’s life.

Green Code Technologies is a supplier of Cisco, and we supply Huawei and Juniper networking alongside HPE, Dell, Samsung, Netgear, Ubiquiti and Asus. We would rather tell you a part is no longer supported, or that we need to check it, than take an order for something that will not do what you need.

The Cisco 12000/6-DC-PEM is a DC Power Entry Module (PEM). It is designed for Cisco 12000 Series Gigabit Switch Routers (GSR).

This module provides -48V DC power input to the router chassis. It converts incoming DC power into the required internal power for system operation.

The PEM is a critical component in powering the router. It ensures stable and continuous power delivery in carrier-grade network environments.

The 12000/6-DC-PEM is typically used in Cisco 12006 chassis and other compatible 12000 series platforms. It supports redundant power configurations, allowing multiple PEMs to be installed for high availability.

This module is designed for hot-swappable installation. It can be replaced or added without shutting down the router, minimizing downtime.

Key functions include:

• Supplying regulated DC power to the system
• Supporting redundant power configurations
• Maintaining high availability in mission-critical networks

It is commonly deployed in:

• ISP core networks
• Telecom infrastructure
• Large enterprise backbone networks

⚠️ Note: The Cisco 12000 series is End-of-Life (EOL). This module is mainly available in refurbished or legacy support markets.

Key Features:

• DC Power Entry Module for Cisco 12000 Series routers
• Supports -48V DC input
• Designed for Cisco 12006 chassis
• Enables redundant power configurations
• Hot-swappable for minimal downtime
• Carrier-grade reliability
