● When installing devices, ensure that the total heat consumption of all devices
in the cabinet is less than or equal to the heat dissipation capability of the
cabinet.
● To prevent heat dissipation from being
aected by air return, devices must be
installed at an interval of 1 U or more in the cabinet. In addition, the middle-
column cabinets support device stacking.
● Ensure that heat dissipation holes on the panel are not blocked.
● When the chassis is installed together with other equipment in the same
cabinet, do not install the chassis near the air exhaust vent of other equipment.
● Determine whether the air exhaust vent
aects adjacent devices to avoid high
temperature of adjacent devices.
Installing a Chassis in a Standard 19-Inch Cabinet
1. Wear an ESD wrist strap or ESD gloves. Ensure that the ESD wrist strap is
grounded and in close contact with your wrist.
2. Install guide rails.
– Adjust the length of one guide rail according to the distance between the
front and rear mounting rails, place the guide rail horizontally at the
determined installation position in the cabinet, and hook it to the
cabinet's front and rear mounting rails.
– Install M6 screws at the front and rear sides of the guide rail, tighten
them to 3 N·m of torque to secure the guide rail to the cabinet, and then
install another guide rail in the same manner.
