A protection assembly for connectors is included on a circuit pack to prevent damage caused when a connector is removed while signal power is stil l being supplied to the circuit pack. More specifically, the protection assemb ly is disposed on the front side of the circuit pack to prevent access to the connector until signal power is automatically cut off from the circuit pack. In one embodiment, the circuit pack is the type having a lever arrangement capable of causing the circuit pack to engage and disengage the backplane of an equipme nt frame. When the circuit pack is engaged in the backplane, signal power is supplied through the connector that is accessible, for example, on the face plate of the circuit pack. The protection assembly includes a first shield member mounted on the face plate of the circuit pack in a location adjacent to the connector. The protection assembly further includes a second shield member mounted or otherwise formed on the lever arrangement. When the circuit pack is engaged in the backplane, the first and second shield members cooperate to prevent access t o the connector protected thereunder. To expose the connector, a technician would have to operate the lever arrangement to separate the first and second shiel d members. Because the circuit pack is disengaged from thebackplane by action of the lever arrangement, signal power supplied to the connector is therefore automatically cut off before the first and second shield members are separat ed to expose the connector.
