• Maintain ambient operating temperature: 32° to 104° F (0° to 40° C).
• Maintain storage temperature: -40° to 158° F (-40° to 70° C).
NOTE
Like all electrical equipment, product lifetimes degrade with increased temperature. If possible,
temperatures should be kept at approximately 78° F (25° C) or lower.
Spacing Requirements. Due to chassis-to-chassis heating, Extreme Networks recommends placing no
more than three BlackDiamond 10808 chassis next to each other.
The following are some general recommendations for installing your BlackDiamond 10808 switch:
• A minimum of 17.32 inches (44 cm) between each set of three BlackDiamond 10808 switch.
Or
• Place patch panels, which are used to patch cables together, between each set of three BlackDiamond
BlackDiamond 10808 switches. A patch panel does not require any power and does not generate any
heat.
NOTE
Up to five adjacent BlackDiamond 10808 switches will continue to function without safety concerns.
However, product lifetime may degrade with continued exposure to high temperatures in close proximity
and long term reliability may be compromised.
Airflow Requirements. To ensure proper airflow through an Extreme Networks switch, refer to the
following recommendations when you are installing your switch:
• The BlackDiamond 10808 switch requires 3 inches (7.62 cm) around both the front and rear of the
chassis (5 inches (12.7 cm) recommended) for proper airflow.
The airflow of the BlackDiamond 10808 switch moves through the power supplies and is independent
of the airflow through the modules as shown in Figure 3. For example, if the power supply fans fail, the
airflow through the module area of the chassis will not cool down the power supplies.
• Airflow for cooling power supplies moves front to back as you face the chassis.
• Airflow for cooling modules moves left to right as you face the chassis.
