Caution: The A2H124-24P and A2H124-48P are PoE-compliant devices. Do not connect
a SecureStack C2 Redundant Power System (C2RPS-SYS) to the power connector.
Otherwise, damage to the device may result.
Precaución: Los dispositivos A2H124-24P y A2H124-48P cumplen con el estándar PoE
(power over ethernet). No conecte una fuente de poder redundante (RPS) SecureStack
C2 (C2RPS-SYS) al cable de corriente. De lo contrario, el dispositivo puede dañarse.
