Backplane and Signal Routing Features

The GE DS200VPBLG1A DS200VPBLG1AFF VME Board distributes power and signals to all twelve rack slots. Each slot has independent power filtering for noise reduction. The board includes active bus termination to prevent signal reflections. Furthermore, it provides diagnostic access to all VME bus lines. Consequently, you can troubleshoot communication issues from a single point.

Installation and Connection Steps

Mount this GE DS200VPBLG1A DS200VPBLG1AFF VME Board as the backplane inside any Mark V rack chassis. First, secure the board using the factory-installed standoffs. After that, insert each VME card into its designated slot carefully. Then, connect the main power supply cables to the power input connectors. Finally, verify all slot guides align properly before powering up the system.

Energy Discharge and Safety Notice

This GE DS200VPBLG1A DS200VPBLG1AFF VME Board stores minimal energy in its decoupling capacitors. However, you must wait 30 seconds after power removal before handling. The eight capacitors discharge through internal bleeder resistors. Never insert or remove cards while the backplane remains powered.

Status Indication and Diagnostics

A green LED indicates the presence of valid backplane power. A red LED illuminates when any power rail falls below specifications. Four additional LEDs show the status of individual voltage rails. These indicators help technicians verify power distribution without removing any cards.
