Description
If you install a front door, it must maintain a minimum of 1.2 inches of clearance to the bezels.
It must be perforated with 50% or more evenly distributed air opening. It should enable easy
access for service personnel and allow the LEDs to be visible through it.
If you install a rear door, it must be perforated with 50% or more evenly distributed air
opening.
Blanking panels should be used as required to prevent air circulation inside the rack.
There is a recommended minimum of 42 inches of clearance in the front and 36 inches of
clearance in the rear of the rack to allow for service area and proper airflow.
The customer-provided rack should have redundant power zones with separate PDU power
strips. Each redundant power zone should have capacity for the maximum power load. When
configured this way, the appliance will remain up and running even with the failure of one
power zone.

the customer-provided PDUs.
