Device cooling
Virtual Services Platform 4000 — device cooling
The VSP 4000 platform has an in-built cooling module that is not removable. Each cooling
module includes four fans providing cooling from front-to-back. There are three 12–volts fans
to maintain optimal operating temperature inside the box. The fans are also speed controlled,
based on the temperature in the box in order to minimize fan noise. Temperature sensors allow
the fan speed controller to properly support the entire unit.
Caution:
Risk of electromagnetic interference:
This device is a Class A product. Operation of this equipment in a residential area is likely
to cause harmful interference, in which case users are required to take appropriate
measures necessary to correct the interference at their own expense.
