Rack-mount chassis RMC-5000

4Ubackplane

The RMC-5000 rack mount chassis provides up to sixteen available slots for any FOM series fiber optic module card. The FOM cards are typically installed from the rear of the chassis, providing electrical and fiber optic connections at the rear of the chassis. A front panel window allows viewing of status leds on each installed card indicating power supply status, fiber optic link status, signal line status, and control or configuration information, depending on the particular card. The chassis backplane allows various support modules to be installed, allowing for future expansion and control options. No active components are an integral part of the chassis backplane, providing high reliability and minimal maintenance issues. Each RMC-5000 will be shipped with one PSM-5000 power supply module. A second PSM-5000 may also be added for power redundancy. If the first PSM-5000 fails, the second PSM-5000 will take over the entire load and carry on normally. Each RMC-5000 is also equipped with an alarm card on the front panel. The alarm card is removable, which allows for maintenance or repair without removal of the chassis itself. The alarm card provides a visual indication of the power supply module presence, the AC power in, the DC power out, and the fan status for each PSM-5000, in addition to an audible alarm. The audible alarm may be set to self-mute when a failure occurs, giving a brief audible tone, and then silencing. A distinctive cadence to the tone allows quick identification in a room full of equipment.
