Extreme Networks BlackDiamond 10K-Series Switch Installation Guide 23

• 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.

• 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.
