Hardware Descriptions
SCC Hardware 0
The SCC design consists of a single circuit pack carrier installed in a small cab-
inet. A maximum of four single-carrier cabinets can be stacked on top of each
other. Each cabinet has vertical slots that hold circuit packs. A blank faceplate
covers each unused slot.
There are two different cabinets used to support the SCC offer:
■ Basic control cabinet (J58890L)
■ Port cabinet (J58890H).
Each stack of single-carrier cabinets requires at least one basic control cabinet.
There is a maximum of three port cabinets per stack. The positions of the
stacked cabinets are labeled from “A'' through “D.” The position of the basic
control cabinet is always labeled ``A.'' Additional port cabinet positions are
labeled ``B,'' ``C,'' and ``D,'' sequentially, as required.
A screw-type latch, located below the identification stripe, secures the front door
to the cabinet. Turning the screw counterclockwise loosens the latch and
releases the door. The cabinet can be secured to the floor, which is required for
earthquake protection, using adapter brackets. Cabinet clips in the front of the
cabinets connect the cabinets together. At the back of the cabinets, a ground
plate connected between cabinets provides ground integrity.
