Overview

The B3G124‐24P and B3G124‐48P are stackable switches that can be adapted and scaled to help meet your network requirements. These switches provide a management platform and an uplink to a network backbone for a stacked group of up to eight B3 switches.

You can also use a redundant DC power supply with these switches to help prevent downtime due to an internal power supply failure in the switch or AC power source.

You can install the switch on a flat surface or into a standard 19‐inch rack with user‐ supplied mounting hardware, and configure the switch functions using the WebView™ application, CLI switching commands, and/or SNMP.
