airflow modules have a red coloring, and port-side exhaust airflow modules have blue coloring. For more

NEBS Compliance
In case of port-side intake airflow, the chassis is not Network Equipment-Building System (NEBS) compliant
by default. To be NEBS compliant, install the NEBS kit by performing these steps:
1. Install the NEBS rack-mount brackets onto the switch.
2. Install the NEBS air baffle by aligning the notches on the baffle with the slots on the brackets and sliding
the ends of the baffle so that the baffle locks into place.
