• adequate space at the front and rear of the switch for access to cables

Verifying environmental suitability

Perform the following procedure to verify environmental suitability before installing the switch.
Procedure
1. Determine the physical location and placement of the switch.
2. Test and assess the physical location to gather environmental ranges for temperature,
humidity, altitude, and acoustic noise.
3. Verify that the installation environment meets all environmental requirements; see
Environmental requirements

Cooling fans and power supplies

VSP 7000 switches require and support two field-replaceable fan trays for switch cooling. VSP 7000
Series switches support two field-replaceable AC or DC power supplies for redundant power
configurations.
Cooling fan trays
Cooling fan trays support hot-swap and are available in two models to support front to back, or back
to front airflow modes. Cooling fan trays are included and must be installed before operating the
switch.
The cooling system is designed to support normal operation over the specified operating range with
a single fan failure. Note that fan noise may increase in this situation. The cooling system is also
designed to operate for a brief period of time on a single fan tray, allowing replacement of a
defective fan tray while the switch is operating.
The following figure shows VSP 7000 Series cooling fan trays.
