Preinstallation Guidelines

• Ensure that the cabinet or rack meets the requirements listed in the

section.

Note

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.

• 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.

Caution

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.

• 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.

Caution

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.

• 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)
