Enclosure Drive Bay Numbering Convention

The enclosure drive bay numbering convention is shown in Figure 23. A drive bay is defined as the

space required to house a single 1.0“ high 3.5 inch disk drive in its carrier module.

IMPORTANT

Drive carrier module must always be fitted in drive locations 1 and 12. This is the minimum configuration

required for the system to operate and provide SES Management Services.

Drive Carrier Conﬁguration

IMPORTANT

Before you begin installation you should become familiar with the configuration requirements of your

SR1202 enclosure, see Table 5.

There must be a drive present in drive locations 1 and 12 to enable SES Communications to operate.

Installing drives in both of these bays will provide redundant SES communication paths.

When planning your system configuration, please remember that:

• All SR1202 enclosure drive bays must be filled with either a drive carrier or dummy drive

carrier, no bays should be left completely empty.

Enclosure Installation Procedures

CAUTION

An SR1202 enclosure with all component parts installed is too heavy for a single person to safely install

alone into a Rack cabinet. The following procedures describe the installation of an SR1202 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 SR1202 modules and components.

Avoid contact with Backplane components and module connectors, etc.

Pre-Requisites

The SR1202 enclosure is designed for installation into an industry standard 19 inch cabinet capable

of holding the unit.

• Minimum depth 700 mm from front flange to rear metalwork (excludes rear cabling).

• Weight: up to 32 kg dependent upon configuration per enclosure.

• A minimum gap of 25 mm (1 inch) clearance between the rack cover and front of drawer; and

50 mm (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 (0.5 mm water gauge).
