Extreme Networks Consolidated "i" Series Hardware Installation Guide

Meeting Site RequirementsBlackDiamond 6816 Spacing Requirements. Due to chassis-to-chassis heating, Extreme Networksrecommends placing no more than three BlackDiamond 6816 chassis next to each other.The following are some general recommendations for installing your BlackDiamond 6816 chassis:• A minimum of 17.32 inches (44 cm) between each set of three BlackDiamond 6816 chassis.Or• Place front-back cooled equipment, such as a BlackDiamond 6808 chassis, between each set of threeBlackDiamond 6816 chassis.Or• Place patch panels, which are used to patch cables together, between each set of three BlackDiamond6816 chassis. A patch panel does not require any power and does not generate any heat.NOTEUp to five adjacent BlackDiamond 6816 chassis will continue to function without safety concerns.However, product lifetime may degrade with continued exposure to high temperatures in close proximityand long term reliability may be compromised.Airflow Requirements. Cooling of an Extreme Networks switch requires proper airflow through thechassis. Make sure there is space around the installed switch for airflow and that cables or otherequipment do not block the air intake or outflow vents on the Extreme Networks switches. It is best tohave 3 to 5 inches (7.62 to 12.7 cm) of clear space in front of the air intake and outflow vents on theswitches. Depending on other conditions in the equipment room or wiring closet, it may be possible toinstall the switches closer to each other. Consult your Extreme Networks Customer Supportrepresentative for guidance.For proper airflow through the switch, leave clear space around the switch as follows:• Summit family of switches—left and right sides of the switch• Alpine 3800 series chassis—left and right sides of the switch• BlackDiamond 6816 and 6804 chassis—around the entire chassis (front, rear, and sides)• BlackDiamond 6808 chassis—front and rear of the chassisThe airflow of the Summit family of switches moves from the left side of the switch to the right side ofthe switch, or from the right side of the switch to the left side of the switch depending on the model.The airflow of the Alpine 3808 moves through the power supplies and is independent of the airflowthrough the chassis as shown in Figure 1. For example, if the power supply fans fail, the airflowthrough the module area of the chassis will not cool down the power supplies.• Airflow for cooling power supplies enters the top of the chassis and moves left to right as you facethe chassis.• Airflow for cooling modules moves left to right as you face the chassis.Extreme Networks Consolidated "e" and "i" Series Hardware Installation Guide 31
