Enterasys Networks manual A2H123-24 Stackable Switch

Overview

•1000BASE‐T RJ45 connectors which can be used in a stack configuration or as standard switch ports when the A2H123‐24 is configured as a standalone switch.

On the rear panel, there is a Redundant Power Supply connector for a connection to a SecureStack C2RPS‐SYS power supply system using the appropriate cable (C2RPS‐PSM cable).

Caution: The A2H123-24 is not a PoE-compliant device. Do not connect a SecureStack PoE Redundant Power System (C2RPS-POE) to the power connector. Otherwise, damage to the device may result.

Precaución: El dispositivo A2H123-24 no cumple con el estándar PoE (power over ethernet). No conecte una fuente de poder redundante (RPS) SecureStack PoE (C2RPS- POE) al cable de corriente. De lo contrario, el dispositivo puede dañarse.

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

Note: The 1000BASE-T built-in RJ45 stacking ports 25 and 26 on the A2H123-24 can be configured as standard 10/100/1000BASE-T switch ports, using the command set switch stackport, when the unit is used in standalone mode.
