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.
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).
Note
Step 2
Repeat with the other shelf bracket.
Step 3
Verify that the shelf brackets are at the same height (using the level or tape measure as desired).
Step 4
Attach the crossbar to the shelf brackets as shown in the above figure, using the 10-32 screws.
Step 5
Insert the slider posts into the shelf brackets as shown in the above figure. Attach them to the rear rack-mounting posts
using a minimum of four 12-24 or 10-24 screws.
Preinstalling the Switch
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.
Connection Guidelines for AC-Powered Systems
For connecting the Cisco MDS 9132T switch AC power supplies to the site power source, follow these basic
guidelines:
•
Each power supply should have its own dedicated branch circuit.
•
Circuits should be sized according to local and national codes.
•
The AC power receptacles used to plug in the chassis must be the grounding type. The grounding
conductors that connect to the receptacles should connect to protective earth ground at the service
equipment.
