2.2.1 Enclosure Bay Numbering Convention
The enclosure bay numbering convention is shown in Figure 2–1 . 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 the rack mount configuration).
The SS-1200-FCAL subsystem is housed in a 4 x 3 enclosure, i.e. 4 bays wide by 3 bays high. The front bays are
numbered 1 to 4 from left to right, viewed from the front. The rear bays are numbered 1 to 4 from right to left,
viewed form the rear. Bays are numbered from 1 (top row) to 3 (bottom row). Module locations are identified from
a matrix of the top and side numbers, e.g. the front ESI/Ops panel should only be installed in front bay 1/1 (top left
when viewed from the front) while the rear ESI/Ops panel should be installed in rear bay 3/1 (top, middle row, when
viewed from the rear).
2.3 Installation
Caution The SS-1200-FCAL Enclosure with all its component parts installed is too heavy for easy installation into
a Rack cabinet. The following procedures describe the installation of the SS-1200-FCAL enclosure and
highlights any critical co-requisite requirements and good handling practices which we encourage you to
follow so as to ensure that a successful installation is achieved in the easiest manner.
Warning Ensure that you have checked and fitted a suitable anti-static wrist or ankle strap and observe all
conventional ESD precautions when handling SS-1200-FCAL modules and components. Avoid
contact with Backplane components and module connectors, etc.
2.3.1 Pre-Requisites
The SS-1200-FCAL Enclosure is designed for installation into an industry standard 19 inch cabinet capable of
holding the unit.
• Minimum depth 580 mm from front flange to rear metalwork (excludes rear cabling).
• Weight (35 to 45 kg dependent upon configuration) per enclosure.
• A minimum gap of 25mm (1inch) clearance between the rack cover and front of drawer; and 50mm (2 inches)
rear clearance between rear of drawer and rear of rack is recommended in order to maintain the correct air flow
around the enclosure.
• The rack should present a maximum back pressure of 5 pascals (0.5mm water gauge).
2.3.2 Rack Mounting Rail Kit
A set of mounting rails is available for use in 19 inch rack cabinets. These rails have been designed and tested to
handle the maximum enclosure weight and to ensure that multiple SS-1200 enclosures may be installed without loss
of space within the rack. Use of other mounting hardware may cause some loss of rack space.
The rack mounting rail kit also incorporates a rear hold down mechanism to ensure shock and vibration immunity.
Please contact us to ensure suitable mount rails are available for the Rack you are using.
