Media converter flexibility
The Allied Telesis MMCR18 is a two rack unit high chassis, which enables network managers to use up to 18 MMC series media converters in a standard 19 inch rack. For redundancy, it can be powered with either one or two Power Supply Units (PSUs).

Power options
The MMCR18 Chassis can be powered with either an AC or DC power supply, eliminating the need for multiple power connections. Allied Telesis also offers an optional hot swappable PSU to eliminate network downtime. The unit saves space in the wiring closet, and minimizes the number of power connections required. Single-unit media converters can be removed from the MMCR18 and deployed individually to accommodate network modifications.

By incorporating a backplane with 18 different power entry modules integrated with the printed circuit board, power is equally distributed among all media converters—whether
using one or two PSUs.

Rack-mount design
Designed with a simple mounting system, each individual media converter is plugged into the back plane and secured with the included mounting rail. The rack-mount chassis includes
six status LEDs on the front panel indicating power, temperature, fan and fault status.
