Chapter 6: Hardware fundamentals and

guidelines

This chapter provides general hardware guidelines to use the Avaya Virtual Services Platform 4000

Series in a network. Use the information in this chapter to help you during the hardware design and

planning phase.

Supported hardware

Release 4.0.50 supports the following VSP 4000 Series models:

1. VSP 4850GTS Series: Includes the 4850GTS (AC), the 4850GTS-PWR+, the 4850GTS-DC.

2. VSP 4450GSX Series: Includes the 4450GSX-PWR+, the 4450GSX-DC and TAA-compliant

4450GSX-PWR+ model.

Note:

The VSP 4450GTX–HT–PWR+ is supported in release 4.0.40.

Platform considerations

This section provides VSP 4000 platform power and cooling considerations. You must properly

power and cool your device, or problems can result.

Platform power supplies

The VSP 4000 series switches support both AC and DC power supplies. One power supply is

installed in the system.

You can install a redundant power supply to support additional power requirements or to provide

power redundancy.

The following table describes the VSP 4000–compatible AC and DC power supplies and their part

numbers (order codes). All the power supplies are EUED RoHS 5/6 compliant.
