Table 57: Cabinet Requirements and Specicaons (Connued)
Cabinet Requirement Guidelines
Cabinet airow requirements When you mount the device in a cabinet, ensure that venlaon through
the cabinet is sucient to prevent overheang, as follows:
• Ensure adequate cool air supply to dissipate the thermal output of the
device or devices.
• Ensure that the hot air exhaust of the chassis exits the cabinet without
recirculang into the device. An open cabinet (without a top or doors)
that employs hot air exhaust extracon from the top ensures the best
airow through the chassis. If the cabinet contains a top or doors,
perforaons in these elements assist with removing the hot air exhaust.
•
Install the device in the cabinet in a way that maximizes the open space
on the side of the chassis that has the hot air exhaust.
•
Route and secure all cables to minimize the blockage of airow to and
from the chassis.
•
Ensure that the spacing of rails and adjacent cabinets is such that proper
clearance exists around the device and cabinet.
• A cabinet larger than the minimum required provides beer airow and
reduces the chance of overheang.
Clearance Requirements for Airow and Hardware Maintenance for
EX4300 Switches
When planning the site for installing an EX4300 switch, you must ensure sucient clearance around the
switch.
