Note:
The 300W and 1000 W AC power supplies use the IEC 60320 C16 AC power cord connector.
Use the order codes to order a replacement for the primary PSU or to order a redundant PSU for
your VSP 4000 system.

Device cooling
VSP 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-volt 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.
