•
The supply circuit, line fusing, and wire size are adequate, as specified by the electrical rating on the device nameplate.
•
The power supply standards are met.
Environmental considerations
For successful installation and operation of the device, ensure that the following environmental requirements are met:
•
Because the SLX 9030/9030-T Switch 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 airflow may not be compatible with your environment. Consult your fan assembly
and power supply FRU kits to determine the correct configuration.
•
The ambient air temperature does not exceed 50°C (122°F) while the switch is operating with front-to-back airflow, or 45°C
(113°F) while the switch is operating with back-to-front airflow.
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 horizontal surface.
The site should meet the following requirements:
•
Maintain the operating environment as specified in “Environmental considerations” under the section
•
For installation on a flat horizontal surface, the SLX 9030/9030T Switch should be installed with its top and bottom covers
parallel to the floor. The SLX 9030/9030T Switch should not be installed upside down.
•
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 space for installing, cabling, and maintaining the devices.
•
Ensure the status LEDs are 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.
Cable management recommendations
Cables can be organized and managed in a variety of ways; for example, use cable channels on the sides of the rack or patch panels to
reduce the potential for tangling the cables. The following list provides some recommendations for cable management:
NOTE
Before plugging a cable to any port, be sure to discharge any static charge stored on the cable by touching the electrical
contacts to ground surface.
•
You should not use tie wraps with fiber-optic cables because they are easily overtightened and can damage the optical fibers.
Velcro-like wraps are recommended.
