2.2.1 Enclosure Bay Numbering Convention
The enclosure bay numbering convention is shown in
. A Bay is defined as the space
required to house a single 1.0" high 3.5 inch disk drive in its carrier module. e.g. a 1 x 4 bay module
would take the space of 1 drive width by 4 drive bays high (in the rack mount configuration).
The Altos S205F / S200F subsystem is housed in a 4 x 4 enclosure, i.e. 4 bays wide by 4 bays high. The
front bays are numbered 1 to 4 from left to right, viewed from the front. Bays are numbered from
1 (top row) to 4 (bottom row). Drive Carrier Module locations are identified from a matrix of the
top and side numbers. The rear bays are numbered 1 to 5 from right to left, viewed from the rear.
Important
Drive carrier module must always be fitted in locations 1/1 (Top Left) and 4/4 (Bottom Right). This
is the minimum configuration required for the system to operate and provide SES Management
Services.
2.3 Enclosure Installation Procedures
Caution
The Altos S205F / S200F Storage System 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
Altos S205F / S200F Storage System 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 fitted and checked a suitable anti-static wrist or ankle strap and observe all
conventional ESD precautions when handling Altos S205F / S200F Storage System modules and
components. Avoid contact with Backplane components and module connectors, etc.
2.3.1 Pre-Requisites
The Altos S205F / S200F Storage System enclosure is designed for installation into an industry
standard 19 inch cabinet capable of holding the unit.
• Minimum depth 531 mm from front flange to rear metalwork (excludes rear cabling).
• Weight: up to 37kg 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 Altos S205F /
S200F 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.
