Enterasys Networks B3G124-24P manual High-Speed Stack Connections, B3G124-48P Stackable Switch

Overview

Caution: The B3G124-24P and B3G124-48P are PoE-compliant devices. Do not connect a non-PoE 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.

High-Speed Stack Connections

The switches have rear‐panel connectors for high‐speed connections in a stack configuration. The high‐speed stacking cables used for the connections are optional items and must be ordered separately. Stacking cables are available in three lengths: 1 foot,

1meter, and 5 meters. See “Connecting High‐Speed Stacking Cables” on page 3‐11 for details on these cables.
