Stack Connections

The switch has front‐panel RJ45 ports 17 and 18 for connections in a stack configuration. The stacking cables used for the connections are standard Category 5 or better UTP cables.

Redundant Power Supply Capability

The SecureStack A2 has power supply redundancy capability when connected to an optional external redundant power supply (RPS). If the internal power supply fails, the RPS assumes the entire load of the SecureStack A2 without interrupting network traffic. The internal power supply and RPS each have their own AC power connection, which enables the connection of each power supply to a different AC power circuit for additional AC power source redundancy.

Caution: The A2H254-16 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: Los dispositivos A2H254-16 no cumplen 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.
