Overview

B3G124-24P Stackable Switch

The B3G124‐24P (Figure 1‐1) has several types of front panel port connections, which include:

Twenty‐four RJ45 ports (10/100/1000 Mbps, 1000BASE‐T copper ports) that also support PoE for connections to IEEE 802.3af compliant PDs (powered devices).

Four 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.

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 B3G124-24P, the 10/100/1000BASE-T built-in RJ45 port 24 is not available and vice-versa.

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

Rear panel Redundant Power Supply connector used to connect to a SecureStack PoE‐compliant Redundant Power Supply (C2RPS‐POE). The switch connects to the SecureStack C2RPS‐POE using a SecureStack C2RPS‐POE cable.

Caution: The B3G124-24P and B3G124-48P are PoE-compliant devices. Do not connect a SecureStack Redundant Power System (C2RPS-SYS) to the power connector. Otherwise, damage to the device may result.

Precaución: Los dispositivos B3G124-24P y B3G124-48P cumplen con el estándar PoE (power over ethernet). No conecte una fuente de poder redundante (RPS) SecureStack (C2RPS-SYS) 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.
