Air Deflector
An air deflector is a sheet-metal part that is mounted on the ONS 15454 M2 shelf to orient the air flow in a
specific direction.
The air deflectors can be mounted in different positions to control the air flow:
• Front to Front— Only ETSI rack
• Front to Back— For ANSI and ETSI racks
• Front to Top— Only ETSI rack
In an ANSI rack, the air deflectors are mounted only on the 23-inch rack configuration.
Air Plenum
Air plenum orients the air flow in the front-to-back direction inside the equipment to be compliant with GR-63
issue 4 requirement.
The air plenum kit has one horizontal and two vertical air plenums. The air that flows from the front top inlet
are channelized to the right vertical plenum, inside the equipment, and then to the exhaust air channel towards
the left vertical air plenum. The air flow is deflected by 90 degrees and exited out in the rear end.
The following figure shows the air flow inside the cabinet.

The following figures show the dimensions of the air plenum relative to the cabinet or rack.
