Back-Panel Descriptions

The back panel of the switch contains the AC power receptacle and the RPS connector.

AC Power Receptacle

The switch automatically adjusts its power setting to any supply voltage in the range of 100 to 240 V alternating current (VAC).

RPS Connector

Connect the optional RPS to the RPS connector. If the switch's internal power unit fails, the redundant power system automatically supplies power to the

switch for uninterrupted operation.

The switch supports the Dell PowerConnect RPS-600 external redundant power system.

NOTE:

See the RPS-600 documentation for more information.

CAUTION:

Do not use the switch with any redundant power system other than the Dell PowerConnect RPS-600.

Management

The following sections describe options for managing the switch.

Web-Based Interface

NOTE:

To access the switch through a web browser, the computer running the web browser must have IP-based network access to the switch.

After you have successfully installed the switch, you can configure the switch, monitor the LED panel, and display statistics graphically using a web browser,

such as Netscape Navigator (version 6.2 and higher) or Microsoft® Internet Explorer (version 5.0).

Command-Line-Driven Console Interface Through a Serial Port or Telnet

You can also connect a computer or terminal to the serial console port or use Telnet to access the switch. The command-line-driven interface provides complete

access to all switch management features. Most of the common commands are described in

Command Line Reference, which is included on the documentation CD.

SNMP-Based Management

You can manage the switch with an SNMP-compatible console program. The switch is compatible with SNMP version 1.0.

The SNMP agent decodes the incoming SNMP messages and responds to requests with MIB objects stored in the database. The SNMP agent updates the MIB

objects every 5 seconds to generate statistics and counters.

The switch supports a comprehensive set of MIB extensions:

RFC 1213 MIB II

RFC 2863 Interfaces Evolution MIB

RFC 2665 Ethernet MIB

RFC 1493 Bridge MIB

RFC 2674 Extended Bridge MIB
