What is a Power Module and How Is It Used in Network Racks?
A power module is a network equipment unit used to distribute electrical power within a rack. It typically provides input power from a mains panel or a UPS to devices such as switches, routers and servers, and aids in managing power in the data center. In data centers, power monitoring and control are often implemented with PDUs to improve reliability and efficiency. Power modules can be rack-mounted or configured in other ways and are suitable for power conditioning, load balancing, and remote power control.

What is a Power Module?
A power module is a passive component that provides multiple electrical outlets and is used to power equipment in a rack. It powers devices such as switches, modems and servers, and racks typically include power inputs. In data centers, PDUs are used to improve power management for reliability and efficiency. A power module can be installed in a rack and, with monitoring capabilities, enables control and optimization of power within the network.
To understand what a power module is, note that it is a passive device that can operate with a single power entry to the rack. In racks, two power sources exist—mains and UPS-connected—and equipment can be connected to various power modules to improve performance and reliability.
Types of Power Modules by Port
Power modules are categorized by the number of output ports. Common types include 3-port, 5-port, 6-port, 8-port and 9-port modules. The port count helps determine the number of devices that can be powered, and higher consumption may require more ports. These modules also serve to protect the health of rack devices.
Types of Power Modules by Unit
In the unit section, power modules are categorized by port count and unit height. Examples include the following:
- 3-port power module with 1U height, grounded, aluminum enclosure
- 5-port power module with 1U height, grounded, aluminum enclosure
- 6-port power module with 1U height, grounded, aluminum enclosure
- 8-port power module with 1U height, grounded, aluminum enclosure
- 8-port power module with 1U height, back-to-back design, aluminum enclosure
- 9-port power module with 1U height, aluminum enclosure
- 19-port module with vertical unit, miniature fuse, aluminum enclosure
- 23-port module with vertical unit, miniature fuse, aluminum enclosure
- 31-port module with vertical unit, miniature fuse, aluminum enclosure
- 33-port module with vertical unit, miniature fuse, aluminum enclosure
