NOTE
As with all electrical equipment, Extreme Networks 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.
Chassis Spacing Requirements
Extreme Networks recommends placing no more than three BlackDiamond chassis next to each other
because of to chassis-to-chassis heating. Use the following spacing guidelines when you install your
BlackDiamond 8800 series switch:
● 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.
Chassis Airflow Requirements
To ensure proper airflow through a BlackDiamond switch, refer to the following recommendations
when you install the switch:
● BlackDiamond 8800 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 8800 series switches, air moves through the power supplies independently of the
airflow through the modules, as shown in
Figure 28 .
