2.6.1. Dummy Drive Carrier Modules
Dummy Drive Carrier modules must be fitted in all unused drive bays
to maintain a balanced airflow.

Blanking Plates must be fitted in any vacant PSU bay or PCI card
slots at the rear of the enclosure to maintain airflow and ensure
correct operation.

Operation of the enclosure system with ANY
modules missing will disrupt the airflow and the drives will not re-
ceive sufficient cooling.
