6.2.1Enclosure Bay Numbering Convention

Warning Operation of the Enclosure with ANY of the plug-in modules missing from the rear of the enclosure 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.

The drive enclosure subsystem is housed in a 60-drive bay enclosure, arranged in four (4) groups. Each group comprises two banks of 15 bays, that is, (as viewed from the front): 12 bays across the enclosure by 5 bays deep. There are two numbering schemes: 1x60 and 2x30. The drive bays are numbered in accordance with the tables shown in Figure 6–2and Figure 6–3,when viewed from above.

Note Drive 61 is optional drive.
