IONPS-D-R1 Description
Transition Networks’ IONPS-D-R1 power module can deliver power or provide optional, redundant DC power for
the ION219 chassis. The ION platform is an intelligent, high-density, multi-protocol system supporting a variety
of network interface devices. Designed for both carrier class and enterprise network applications where multiple
points of fiber integration and secure network management of the fiber interface devices is essential.
The ION219 chassis can support up to two power supply modules which mount in the rear of the chassis.
A single power supply can be used to power all the devices installed in the chassis; however the system can be
made redundant with the use of a second power supply. In this configuration, the power supplies operate in an
instant-fail-over mode. The IONPS-D-R1 is shown below:
