• An Enclosure System Interface/Operators Panel (ESI/Ops) plug-in module (see Figure 1–5 ).
• Blank plates, as required to complete your required configuration and installation.
• FC-AL Drive Carrier Modules and associated front dummy fascia plates. (See Figure 1–10 ).
• FC-AL Input/Output Modules. (See Figure 1–11 ).
• A third Power Supply/Cooling Module may be required to support some 10 000 rpm disk drives.
1.2.1 Enclosure Chassis
The chassis consists of two segmented chassis assemblies, constructed from a number of aluminum extruded
sections, with a Backplane PCB between them. The chassis assemblies each contain 12 'Bays', each of which
accommodates a plug-in module (larger modules can be accommodated using multiple bay spaces). The Backplane
PCB provides logic level signal and low voltage power distribution paths. A SS-1200-FCAL chassis is shown in
Figure 1–2 and Figure 1–3 .
• A Bay is defined as the space required to house a single 1.6" high 3.5 inch disk drive in its carrier module. e.g.
a 1 x 3 bay module would take the space of 1 drive width by 3 drive bays high (in rack mount configuration).
• A 4 x 3 Chassis fitted with 19 inch Rack mounting features enables it to be fitted to standard 19 inch racks. It
uses 4EIA units of rack space.
