Description

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® management application, or the WebView 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.5. Proceed to “Guidelines for Flat Surface Installation” on page 2‐3. For a rackmount installation, proceed to “Rack Mounting the Switch” on page 2‐3. Guidelines for Flat Surface Installation Locate the switch within 182.88 cm (6 ft) of its power source and on a surface as shown in Figure 2‐1 on page 2‐3. If an optional redundant power system is going to be installed and connected to the 14‐pin Redundant Power Supply input connector on the rear of the switch, refer to “Installing and Connecting a Redundant Power System” on page 2‐10. If you are installing several switches in a stack, proceed to “Connecting Stacking Cables” on page 2‐5. If the switch is being installed as a standalone switch, proceed to “Connecting AC Power” on page 2‐9 for power connection instructions.
