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

you to follow so as to ensure that a successful installation is achieved in the easiest manner.

conventional ESD precautions when handling SR1202 modules and components.
Avoid contact with Backplane components and module connectors, etc.
