Cooling fans and power supplies

VSP 7000 switches require and support two field replaceable fan trays for switch cooling. VSP
7000 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.
Power supply compatibility with cooling fans
Power supplies support hot-swap and are available in two models to support cooling fan airflow
modes.
If you are using front to back cooling or back to front cooling, ensure that you use compatible
power supplies that match the cooling fan airflow.
Redundant power supply configurations
If you install two power supplies for redundancy, the switch can perform load sharing.
You can hot-swap power supplies for non stop, uninterrupted switch operation.
Power supply monitoring
For enhanced monitoring, power supplies send information to the switch software about the
type (AC or DC, and airflow mode).
