Preinstallation Guidelines
Airflow Considerations
The switch comes with fan modules and power supply units that have either port-side intake or port-side
exhaust airflow for cooling the switch. If you are orienting the switch with the FC ports facing a cold aisle,
make sure that the switch has a port-side intake fan and power supply modules with red colorings. If you are
orienting the switch with the fan and power supply modules facing a cold aisle, make sure that the switch has
port-side exhaust fan and power supply units with blue colorings. All fan modules and power-supply modules
must have the same direction of airflow.
Connection Guidelines for AC-Powered Systems
To connect to the Cisco MDS 9396V switch AC power supply units to the site power source, follow these
guidelines:
• For power redundancy, each power supply should be connected to a separate power feed (at a minimum,
separate branch circuits).
• Circuits should be sized according to local and national codes.
• The AC power receptacles that are used to power the chassis must be the grounding type. The grounding
conductors that connect to the receptacles should connect to protective earth ground in the service
equipment.
Installation Guidelines
Follow these guidelines when installing the Cisco MDS 9396V Switch:
• Plan your site configuration and prepare the site before installing the switch.
• Each new switch requires a license; see the Cisco MDS 9000 Series Licensing Guide for instructions on
installing a license.
• Ensure there is adequate space around the switch to allow for servicing the switch and for adequate
airflow (airflow requirements are listed the Technical Specifications section).
• Ensure the air-conditioning meets the heat dissipation requirements listed the Technical Specifications
section.

Preinstallation Guidelines

• Ensure that the cabinet or rack meets the requirements listed in the Cabinet and Rack Requirements
section.
If the front cabinet mounting rails are not offset from the front door or bezel panel
by a minimum of 3 inch (7.6 cm), and a minimum of 5 inch. (12.7 cm),
respectively, and cable management brackets are installed on the front of the
chassis, the chassis should be mounted rear-facing to ensure the minimum bend
radius for fiber-optic cables.
Note
Jumper power cords are available for use in a cabinet.
Note
•Ensure the chassis is adequately grounded. If the switch is not mounted in a grounded rack, we recommend
connecting both the system ground on the chassis and the power supply ground to an earth ground.
• Ensure the site power meets the power requirements listed in the Technical Specifications section. If
available, you can use an uninterrupted power supply (UPS) to protect against power failures.
Avoid UPS types that use ferro-resonant technology. These UPS types can become
unstable with systems such as the Cisco MDS 9000 Family, which can have
substantial current draw fluctuations because of fluctuating data traffic patterns.
Caution
• Ensure that electrical circuits are sized according to local and national codes.
For North America, the 300 W power supplies require a 20 A circuit. If you are using a 200 or 240 VAC
power source in North America, the circuit must be protected by a two-pole circuit breaker.
To prevent loss of input power, ensure the total maximum loads on the circuits
supplying power to the switch are within the electrical current ratings for circuit
wiring and breakers.
Caution
• Use the following screw torques when installing the switch:
• Captive screws: 4 in-lb (0.45 N·m)
• M3 screws: 4 in-lb (0.45 N·m)
• M4 screws: 12 in-lb (1.36 N·m)
• M6 screws: 40 in-lb (4.5 N·m)
• 10-32 screws: 20 in-lb (2.26 N·m)
• 12-24 screws: 30 in-lb (3.39 N·m)
