To install the shelf brackets in an EIA rack, follow these steps:
Step 1 Position a shelf bracket inside the rack-mounting posts as shown in the above figure. Align the screw holes at the front
of the shelf bracket with the holes in the front rack-mounting post. Then attach the shelf bracket to the front rack-mounting
post using a minimum of four 12-24 or 10-24 screws.
Note The bottom hole of the shelf bracket should align with the bottom hole of a rack unit on the rack-mounting post
(the hole immediately above the 1/2 in. spacing).
Step 2 Repeat with the other shelf bracket.

Airflow Considerations
The switch comes with fan and power supply modules that have either port-side intake or port-side exhaust
airflow for cooling the switch. If you are positioning the port end of the switch in a cold aisle, make sure that
the switch has port-side intake fan and power supply modules with red colorings. If you are positioning the
fan and power supply modules in a cold aisle, make sure that the switch has port-side exhaust fan and power
supply modules with blue colorings. All fan and power supply modules must have the same direction of
airflow.
