Cabinet Requirements for EX3300 Switches
You can mount the switch in a cabinet that contains a 19-in.
rack.
Cabinet requirements consist of:
- Cabinet size
- Clearance requirements
- Cabinet airflow requirements
Table 27 provides the cabinet requirements and specifications for
the switch.
Table 27: Cabinet
Requirements and Specifications for the Switch
Cabinet Requirement | Guidelines |
|---|
Cabinet size | - You can mount the switch in a cabinet that contains a
19-in. rack as defined in Cabinets, Racks, Panels, and Associated
Equipment (document number EIA-310–D) published by
the Electronics Industry Association (http://www.ecianow.org/standards-practices/standards/) .
- The minimum cabinet size must be able to accommodate the
maximum external dimensions of the switch.
|
Cabinet clearance | - 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 airflow requirements | When you mount the switch 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 switch or switches.
- Ensure that the hot air exhaust of the chassis exits the
cabinet without recirculating into the switch. 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 switch 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 switch and cabinet.
- A cabinet larger than the minimum required provides better
airflow and reduces the chance of overheating.
