Preparing the Site
Airflow Requirements
The switch is positioned with its ports in either the front or the rear of the rack, depending on your cabling
and maintenance requirements. To identify the airflow options for your switch, see the user-replaceable
components in the Overview section of this document. Position the fan and power supply modules to move
the coolant air from the cold aisle to the hot aisle in one of these ways:
• Port-side intake airflow—Cool air enters the chassis through the port end in the cold aisle and exhausts
• Single-direction airflow—The direction of the installed fan modules determines the airflow.
• For the N9364E-SG2-Q switch, port-side exhaust configuration is not supported.
Note
Rack and Cabinet Requirements
Install these types of racks or cabinets for your switch:
• Standard perforated cabinets
• Solid-walled cabinets with a roof fan tray (bottom-to-top cooling)
• Standard open four-post Telco racks
Work with your cabinet vendors to determine which of their cabinets meet these requirements or see the Cisco
Technical Assistance Center (TAC) for recommendations:
• Use a standard 19-inch (48.3-cm), four-post Electronic Industries Alliance (EIA) cabinet or rack with
• The depth of a four-post rack must be 24 to 32 inches (61.0 to 81.3 cm) between the front and rear
Also, you must have power receptacles that are located within reach of the power cords that are used with the
switch.
Warning
through the fan and power supply modules in the hot aisle.
• To prevent the switch from overheating and shutting down, position the air intake for the switch in a
cold aisle. The fan and power supply modules must have the same direction of airflow.
• The airflow direction must be the same for all power supply and fan modules in the chassis. Airflow
direction is front (ports) to back (fans and power supplies) of the chassis.
mounting rails that conform to English universal hole spacing per section 1 of the ANSI/EIA-310-D-1992
standard.
mounting rails (for proper mounting of the bottom-support brackets or other mounting hardware).
Statement 1048 Rack Stabilization
The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor before installation
or servicing. Failure to stabilize the rack can cause bodily injury.
