Extreme Networks 12800 Series manual Humidity, BlackDiamond Family Chassis Spacing Requirements

Site Preparation

NOTE

As with all electrical equipment, product lifetimes degrade with increased temperature. If possible, temperatures should be kept at approximately 78° F (25° C) or lower.

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.

BlackDiamond Family Chassis Spacing Requirements

Because of chassis-to-chassis heating, Extreme Networks recommends placing no more than three chassis next to each other. In addition, Extreme Networks recommends the following general principles for equipment placement:

●Leave a minimum of one empty 19-inch rack between two sets of three adjacent BlackDiamond switches.

or

●Place patch panels between two sets of three adjacent BlackDiamond switches. A patch panel does not require any power and does not generate any heat.

NOTE

Up to five adjacent 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 a BlackDiamond 12800 series switch, refer to the following recommendations:

●BlackDiamond 12800 series switches require a minimum of 1.5 inches (4 cm) around both the left and right sides of the chassis from any cabinet wall or other obstruction for proper airflow.

●Air temperature measured approximately 1 inch (2.5 cm) from the fan inlet should be less than 104 °F (40 °C).

In the BlackDiamond 12800 series switches, airflow through the power supplies is independent of the airflow through the modules as shown in Figure 20.
