The enclosure has a mechanism that enables the card cage to tilt approximately 45° for easy access to facilitate
Lightning Protection Unit (LPU) service. For more information, refer to
“Lightning Protection Unit” on page 25
.
Two knobbed retainer screws at the base of the card cage (one on each side) lock the card cage in its normal level
position which helps prevent tilting during severe vibrations. The cable stubs shield is grounded to the card cage
base through a short braided wire which is connected to the card cage base. The card cage itself is grounded
through a ribbon ground connected between the card cage base and side..
