2.4 Switch Architecture

The switch transports multiple packets at wire-speed and low latency on all ports simultaneously. It operates in full-duplex mode on all ports to effectively double the bandwidth of each connection.

This switch uses store-and-forward technology to ensure maximum data integrity. With this technology, the entire packet must be received into a buffer and checked for validity before being forwarded. This prevents errors from being propagated throughout the network.

2.5 Network Management Options

You can manage the switch over the network with a Web browser or Telnet application. Its built-in network management agent helps you manage NMP or RMON (Groups 1, 2, 3, 9) protocols.

NOTE: For a detailed description of the management features, refer to the user’s manual. To download the user manual, visit www.blackbox.com and enter LGB5128A in the search bar, then download the user’s manual, or download the user’s manual from ftp://ftp.blackbox.com/anonymous/manuals/L/LGB5128A_USER_rev1.pdf.

2.6 Operation of Web-based Management

The default values of the LGB5128A are listed below:

IP address: 192.168.1.1

Subnet mask: 255.255.255.0

Default gateway: 192.168.1.254

User name: admin

Password: (blank)

First, configure your device’s Ethernet interface to be in the same subnet as the LGB5128A switch. Then, you can browse to the LGB5128A. For example, if you type http://192.168.1.1, it will show the login screen and ask you to input a username and password to login and authorize access to the switch.

The default username is “admin,” and the default password is blank. The first time you access the switch, enter the default username. At the password prompt, simply press the enter key. Next, click the “Login” button.
