Description of the AC power supplies
AC drawer locking tab
The AC power supply drawers have a locking mechanisn that prevents anyone from removing a
drawer while the unit has a power cord plugged in. Refer to the diagram below.
Before you plug the cord into the power supply, you can see that a plate covers part of the AC
receptacle. You can easily slide this plate up to insert the cord. The locking tab stays up in the
locked position and prevents the drawer from being pulled out while the power cord is plugged
in.
The locking tab is at the top edge of the sliding plate. Immediately below the sliding plate and
at either side of the receptacle are two small screws. These screws attach the AC receptacle to
the drawer front. They also are used to attach a power cord clamp. The screws can be
untightened 3 or 4 turns to allow the clamp to slide under, but they should never be fully
removed.
How to obtain a clamp
Lucent does not supply cord clamps. Clamps are available from the Panel Components
Corporation, P/N 85910051, at (515) 673-5000.
