Figure 6. Base plate Locking Device

It is not allowed to manipulate CEX bus base plates in a powered and running

system. Before changing or removing a base plate, all CEX modules on that

segment must be removed.

To prevent damage to the pins, be sure the base plate plugs and sockets are fully

aligned as the units interconnect. Under no circumstances use excessive force.

It is essential that the locking device is placed in the LOCKED position to avoid

possible problems caused by vibration and/or intermittent grounding.
