Overview

Overview

The B2G124‐24, B2G124‐48, and B2H124‐48 are stackable Fast Ethernet and Gigabit Ethernet switches, which can be adapted and scaled to help meet your network needs. These switches provide a management platform and uplink to a network backbone for a stacked group of up to eight B2 switches. The four built‐in Small Form Pluggable (SFP) interface slots provide you with the option of installing Mini‐GBICs for 1000BASE‐SX/LX fiber‐optic connections and 1000BASE‐T copper connections.

The switches also support the use of a redundant DC power supply 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.

B2G124-24 and B2G124-48

The B2G124‐24 (Figure 1‐1) and B2G124‐48 (Figure 1‐2) have several types of front and rear panel port connections, which include:

•RJ45 ports (10/100/1000 Mbps, 1000BASE‐T copper ports), 24 on the B2G124‐24 and 48 on the B2G124‐48

•SFP slots that provide you with the option of installing Small Form Pluggable (SFP) Mini‐GBICs for 1000BASE‐SX/LX fiber‐optic connections and 1000BASE‐T copper connections.

•Rear panel connectors for high‐speed connections in a stack configuration

•Rear panel Redundant Power Supply connector for a connection to a SecureStack C2RPS‐SYS power supply system using the appropriate cable (C2RPS‐PSM).

Caution: The B2G124-24, B2G124-48 and B2H124-48 are not PoE-compliant devices. Do not connect a SecureStack C2 PoE Redundant Power System (C2RPS-POE) to the power connector. Otherwise, damage to the device may result.

Precaución: Los dispositivos B2G124-24, B2G124-48 y B2H124-48 no cumplen con el estándar PoE (power over ethernet). No conecte una fuente de poder redundante (RPS) SecureStack C2 PoE (C2RPS-POE) al cable de corriente. De lo contrario, el dispositivo puede dañarse.

The 10/100/1000 Mbps fixed front panel ports can operate in either half‐duplex or full‐ duplex mode, as determined by Auto‐Negotiation.

Note: The Mini-GBIC ports cannot be active simultaneously with their corresponding 10/100/1000BASE-T ports. For example, if SFP port 24 establishes a link first on the B2G124-24, the 10/100/1000BASE-T built-in RJ45 port 24 is not available and vice-versa.
