Features

Stack Connections

The switches have front panel RJ45 ports for connections in a stack configuration. The stacking
cables used for the connections must be standard Category 5 or better UTP cable.

Redundant Power Supply Capability

The A4 has power supply redundancy capability when connected to an optional external
redundant power supply:
• STK-RPS-150PS, a 150 watt DC power supply for redundant power for A4 switches.
If the internal power supply fails, the RPS automatically assumes the role of the internal power
supply without interrupting network traffic. The internal power supply and RPS each have their
own AC power connection, which enables the connection of each power supply to a different AC
power circuit for additional AC power source redundancy.

Management

Management of the switch can be either in-band or out-of-band. In-band remote management is
possible using Telnet, Enterasys Networks' NetSight
application. Out-of-band management is provided through the DB9 Console port connector on the
front panel using a VT100 terminal or a VT100 terminal emulator.

Switch Configuration Using WebView

Enterasys Networks' HTTP-based Web management application (WebView) is an intuitive web
tool for simple management tasks.

Switch Configuration Using CLI Commands

The CLI commands enable you to perform more complete stackable switch configuration
management tasks.
For CLI command set information and how to configure the module, refer to the Enterasys A4 CLI
Reference.

Standards Compatibility
