Stack Connections
The switch has front‐panel RJ45 ports 25 and 26 for connections in a stack configuration.
The stacking cables used for the connections are standard Category 5 or better UTP cable.
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 A2H124-24FX 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 A2H124-24FX 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.
