Table 48: Cabinet Requirements and Specicaons
(Connued)
Cabinet Requirement Guidelines
Cabinet clearance
• The outer edges of the front mounng brackets extend the width of the
chassis to 19 in. (48.2 cm).
• The minimum total clearance inside the cabinet is 30.7 in. (78 cm)
between the inside of the front door and the inside of the rear door.
Cabinet airow requirements When you mount the device in a cabinet, ensure that venlaon through
the cabinet is sucient to prevent overheang, 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
recirculang into the device. An open cabinet (without a top or doors)
that employs hot air exhaust extracon from the top ensures the best
airow through the chassis. If the cabinet contains a top or doors,
perforaons 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 airow 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 beer airow and
reduces the chance of overheang.
