Installation and safety considerations

Electrical considerations

To install and operate the switch successfully, ensure compliance with the following requirements:
•
The primary outlet is correctly wired, protected by a circuit breaker, and grounded in accordance with local electrical codes.
•
The supply circuit, line fusing, and wire size are adequate, as specified by the electrical rating on the switch nameplate.
•
The power supply standards are met.

Environmental considerations

For successful installation and operation of the switch, ensure that the following environmental requirements are met:
•
Because the Brocade ICX 7750 can be ordered with fans that move air either front to back or back to front, be sure to orient your
switch with the airflow pattern of any other devices in the rack. All equipment in the rack should force air in the same direction to
avoid intake of exhaust air.
•
Some combinations of intake and exhaust airflows may not be compatible with your environment. Consult your fan and power
supply module FRU kit to determine the correct configuration.
•
The ambient air temperature does not exceed 50°C (122°F) while the Brocade ICX 7750-26Q or Brocade ICX 7750-48F switch
is operating, or 40°C (104°F) while the Brocade ICX 7750-48C switch is operating.

Location considerations

Before installing the device, plan its location and orientation relative to other devices and equipment. Devices can be mounted in a
standard 19-inch equipment rack or on a flat surface.
The site should meet the following requirements:
•
Maintain the operating environment as specified in
•
Allow a minimum of 3 in. of space between the front and the back of the device and walls or other obstructions for proper airflow.
•
Allow at least 3 in. of space at the front and back of the device for the twisted-pair, fiber-optic, and power cabling.
•
Allow access for installing, cabling, and maintaining the devices.
•
Allow the status LEDs to be clearly visible.
•
Allow for twisted-pair cables to be routed away from power lines, fluorescent lighting fixtures, and other sources of electrical
interference, such as radios and transmitters.
•
Allow for the unit to be connected to a separate grounded power outlet that provides 100 to 240 VAC, 50 to 60 Hz, is within 2
m (6.6 ft) of each device, and is powered from an independent circuit breaker. As with any equipment, a filter or surge suppressor
is recommended.

Cabinet considerations

For successful installation and operation of the switch in a cabinet, ensure the following cabinet requirements are met:
•
The cabinet must be a standard EIA cabinet.
•
The equipment in the cabinet is grounded through a reliable branch circuit connection and maintains ground at all times. Do not
rely on a secondary connection to a branch circuit, such as a power strip.
•
Airflow and temperature requirements are met on an ongoing basis, particularly if the switch is installed in a closed or
multicabinet assembly.
•
The additional weight of the switch does not exceed the cabinet's weight limits or unbalance the cabinet in any way.
•
The cabinet is secured to ensure stability in case of unexpected movement, such as an earthquake.
