Table 34: Cabinet Requirements and Specifications (continued)
Guidelines
Cabinet
Requirement
•
The outer edges of the mounting brackets extend the width of the chassis to 19 in. (48.2 cm).
•
The minimum total clearance inside the cabinet is 30 in. (76.2 cm) between the inside of the front
door and the inside of the rear door.
Cabinet clearance
When you mount the device in a cabinet, ensure that ventilation through the cabinet is sufficient to
prevent overheating.
•
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 recirculating into the device.
An open cabinet (without a top or doors) that employs hot air exhaust extraction from the top
ensures the best airflow through the chassis. If the cabinet contains a top or doors, perforations 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 dress all cables to minimize the blockage of airflow to and from the chassis.
•
Ensure that the spacing of rails and adjacent cabinets is such that there is proper clearance around
the device and cabinet.
•
A cabinet larger than the minimum required provides better airflow and reduces the chance of
overheating.

Clearance Requirements for Airflow and Hardware Maintenance for EX2300 Switches
When planning the site for installing an EX2300 switch, you must allow sufficient
clearance around the installed switch. Figure 23 on page 62 shows the clearance
requirements for the EX2300-C switch models. Figure24 on page62 shows the clearance
requirements for EX2300 switches, except the EX2300-C switch model, with PoE
capability. The depth of EX2300 switches, except the EX2300-C switch model, without
PoE capability is 10 in. (25.4 cm).
