A2H123-24 Stackable Switch - Enterasys SecureStack A2 A2H123-24 Hardware Installation Manual

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

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.
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.
