For Network Equipment-Building Standards (NEBS) compliant installations, perform the following steps:
a) Stick the labels available with CAT-A-AIRFLOW kit on to each side of the switch as shown in the
following illustration. Make sure you align the holes in the labels with the screw holes in the chassis.
b) Secure the brackets to the chassis using the flat head screws provided with the bracket.
NEBS is supported only with four-point mounting.
Note
To comply with NEBS, GR-63, the switch airflow direction must be from the front (cold) to the rear
(hot). Attaching the air vent labels in the CAT-A-AIRFLOW kit ensures proper airflow by preventing the
intake of hot air into the chassis through the side vents, which could otherwise result in overheating of the
chassis.
