RM16M Universal Data Shelf fits any standard 19" or 23" electronics rack. It supports Motorola's broad family of RM16M communications cards. Snap-to-backplane segments permit an exact equipment match on a slot-by-slot basis. Plug-and-play installation optimizes uptime. All RM16M cards have their own power supply. Problems with an individual device will not disable an entire shelf. Convection cooling leaves no fans to break down. The shelf supports up to 16 Motorola RM16M cards.
