Introduction
1.1 The SS-1200-FCAL System
.
1.2 The Enclosure Core Product
The SS-1200-FCAL design concept is basedon a subsystem together witha set of plug-in modules. The Salient SS-
1200-FCAL subsystem as supplied comprises:
• Chassis with Backplane installed.
• Power Supply/Cooling plug-in modules, in accordance with your required configuration (see Figure 1–4).
Figure 1–1 The SS-1200-FCAL System

SS-1200-FCAL User Guide

• 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.

1.2.2 Tower Option
An optional tower kit is available, which can be fitted to the rack chassis described here. Separate documentation is
provided with this option.
1.3 The Plug-in Modules
An SS-1200-FCAL Enclosure requires one or more of the following modules for normal operation:
1.3.1 Power Supply/Cooling Module
Two Power Supply/Cooling modules are supplied mounted inthe rear of the enclosure as part of the subsystem core
product. (Figure 1–4)
Up to three Power Supply/Cooling plug-in modules can be installed in the rear of the Enclosure.
PSU voltage operating ranges are nominally 115V or 230V AC, selected by means of a switch on the front of the
PSU, shown in Figure 2–3.
.
An LED mounted on the front panel of the Power Supply/Cooling Module (see Figure 2–3) indicates the status of
the PSU and the fans.

1.3.5 Blank Plates
Blank plates must be fitted over all vacant bays at the rear of the enclosure as shown in Figure 1–12. There are three
sizes of blank plate available:
–Single bay Rear blank plates
–1x2 bay Rear blank plates
–1x3 bay Rear blank plates
Warning Operation of the Enclosure with
ANY blank plates or rear modules missing will disrupt the airflow
and the drives will not receive sufficient cooling. It is
ESSENTIAL that all rear apertures are filled
before operating the unit.
1.3.6 Multiple Power Supply/Cooling Modules
If you have two or three Power Supply/Cooling modules fitted, theyoperate together. If one fails the others maintain
the power supply and cooling while you replace the faulty unit.
Module replacement should only take a few minutes to perform but must be completed within 20 minutes from
removal of the failed module. Alternatively, if there is no replacement module available, a blanking plate could be
fitted after removing the faulty module.
Note Three Power Supply/Cooling modules must be fitted if you are installing
drives consuming more than 21 watts (operational), e.g. 10 000 rpm 9GB HH drives.
1.3.7 Visible and Audible Alarms
The functional modules have associated status LEDs. The ESI/Ops Panel shows a consolidated status for all
modules.
LEDs show constant green for good or positive indication and flashing green/red if non-critical conditions exist.
Constant Amber LEDs indicate there is a fault present within that module.
The ESI/Ops Panel also incorporates an Audible Alarm to indicate when a fault state is present and also an Alarm
Mute push-button.
Warning The Power Supply/Cooling module is not an operator removable part. It must only be removed by
a qualified service engineer who has knowledge of the hazards present within the module.
