Installing the Air-Duct Option
The NE1072T supports an optional 1U air duct to maximize air flow conditions in a
19” rack.
The air-duct option is only supported when the switch is installed on a 4-post rack
mount kit basis. If the switch is installed on a rack using default 2-post rack mount
kit, it does not support the air-duct option.
For information on removing an installed 1U air-duct option, see “Removing the
Air-Duct Option” on page 71 .
The following table lists the parts included with the air-duct option kit.
Attention: The rack-mounting frame may not be able to support the weight of the
networking switch with only the front post mounting brackets (2-post application).
If the switch has an undesirable amount of sag, it is recommended to use a 4-post
mounting kit.
Attention: For earthquake stability, mount the switch in a 4-post rack.
