Humidity; Chassis Airflow Requirements; Electrostatic Discharge; Rack Specifications And Recommendations - Extreme Networks BlackDiamond X8 Series Hardware Installation Manual

Humidity

To maximize equipment life, keep operating humidity between 50% and 70% relative humidity
(non-condensing) during typical operation. The equipment can operate between 10% and 95% relative
humidity (non-condensing) for short intervals.

Chassis Airflow Requirements

To ensure proper airflow through a BlackDiamond switch, refer to the following recommendations
when you install the switch:
For proper airflow, BlackDiamond X8 series switches require a minimum of 24 inches (61 cm)
●
between any cabinet wall or other obstruction and the front and back of the chassis.
Air temperature measured approximately 1 inch (2.5 cm) from the front of I/O slot 1 should be less
●
than 104 °F (40 °C).

Electrostatic Discharge

Your system must be protected from static electricity or electrostatic discharge (ESD). Take the following
measures to ensure optimum system performance:
Remove materials that can cause electrostatic generation (such as synthetic resins) from the wiring
●
closet. Check the appropriateness of floor mats and flooring.
Connect metal chassis, conduit, and other metals to ground using dedicated grounding lines.
●
Use electrostatically safe equipment and the ESD-preventive wrist strap that is provided with your
●
equipment. All switches have ESD-preventive wrist strap connectors and are shipped with an
ESD-preventive wrist strap as shown in
Figure 10: Using an ESD-preventive Wrist Strap

Rack Specifications and Recommendations

Racks should conform to conventional standards. In the United States, use EIA Standard RS-310C:
Racks, Panels, and Associated Equipment. In countries other than the United States, use IEC Standard
297. In addition, verify that your rack meets the basic mechanical, space, and earthquake requirements
that are described in this section.
