Table 22: Cabinet Requirements for the EX4600 Switch (Connued)
Cabinet Requirement Guidelines
Cabinet airow
requirements
When you mount the switch in a cabinet, ensure that venlaon through the cabinet
is sucient to prevent overheang.
• Ensure that the cool air supply you provide through the cabinet adequately
dissipates the thermal output of the switch (or switches).
• Ensure that the cabinet allows the chassis hot exhaust air to exit the cabinet
without recirculang into the switch. An open cabinet (without a top or doors)
that employs hot air exhaust extracon from the top allows 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.
•
The EX4600 fans exhaust hot air either through the vents on the port panel or
through the fans and power supplies. Install the switch in the cabinet in a way
that maximizes the open space on the FRU side of the chassis. This maximizes the
clearance for crical airow.
•
Route and dress all cables to minimize the blockage of airow to and from the
chassis.
• Ensure that the spacing of rails and adjacent cabinets allows for the proper
clearance around the switch and cabinet.
