Installing the Switch Chassis

port-side exhaust airflow and you must position the module side of the switch in a cold aisle. If there is

burgundy coloring on the fan modules, the switch is configured for port-side intake airflow and you must

position the port side of the switch in a cold aisle.

• Ensure that the chassis can be adequately grounded. If the switch is not mounted in a grounded rack, we

recommend connecting the system ground on the chassis directly to an earth ground.

• Ensure that the site power meets the power requirements for the switch. If available, you can use an

uninterruptible power supply (UPS) to protect against power failures.

• Ensure that circuits are sized according to local and national codes. Typically, this often requires one or

both of the following:

Caution

Avoid UPS types that use ferroresonant technology. These UPS types can become

unstable with the switch, which can have substantial current draw fluctuations

because of fluctuating data traffic patterns.

• AC power supplies typically require at least a 15-A or 20-A AC circuit, 100 to 240 VAC, and a

frequency of 50 to 60 Hz.

Caution

To prevent loss of input power, ensure the total maximum loads on the circuits

supplying power to the switch are within the current ratings for the wiring and

breakers.

Note

For AC input application, please refer to the statement below:

Warning

Statement 1005—Circuit Breaker

This product relies on the building's installation for short-circuit (overcurrent)

protection. Ensure that the protective devices is rated not greater than 20A (North

America), 16A (Europe), and 13A (UK).

Note

For DC input application, please refer to the statement below:

Warning

This product relies on the building's installation for short-circuit (overcurrent)

protection. Ensure that the protective devices is rated not greater than 40A for

the regular DC power supplies (rated 48-60VDC) and 10A for the HVDC power

supplies.
