SW0 FD Control Cabinet
3.6
The SX-200 FD Control Cabinet is similar to a Personal Computer (PC) Tower
cabinet. The cabinet has a steel frame and is approximately 22.9 cm wide x 48 cm
high x 42.0 cm deep (9 inches x 19 inches x 16.5 inches). The internal structure of
the cabinet is designed to hold the system cards and components. The front panels
are plastic and can be removed with a screwdriver, allowing access to the cards. The
metal cover that encases the top and sides of the cabinet can also be lifted off the
frame after removing some screws.
The Control cabinet has a single bay that holds one Main Control Card, one Personal
Computer (PC) power supply, one Control Resource Card and two D&k Drives. One
or two Quad Fiber Interface Module Carrier cards are set in the rear panel of the
cabinet. A Quad Fiber Inter-face Carrier Card holds four Fiber Interface Modules.
Figure 3-6 shows the SX-200 FD Control Cabinet.

Control Cabinet. Each Peripheral Cabinet has a single bay that contains a Bay
Power Supply, a Bay Control Card, a Peripheral Fiber Interface Carrier Card, a Fiber
Interface Module, and up to eight Peripheral Interface Cards.
The SX-200 FD Peripheral Cabinet is shown in Figure 3-7.
