required relative order.
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 cabinet.
For EX300 nodes, there is a recommended minimum of 42 inches of clearance in the front
