Caution: The A2H254-16 is not a PoE-compliant device. Do not connect a SecureStack

C2 PoE Redundant Power System (C2RPS-POE) to the power connector. Otherwise,

damage to the device may result.

Precaución: El dispositivo A2H254-16 no cumple con el estándar PoE. No conecte una

fuente de poder redundante (RPS) SecureStack C2 PoE (C2RPS-POE) al cable de

corriente directa. De lo contrario, el dispositivo puede dañarse.

Note: The 1000BASE-T built-in RJ45 stacking ports 17 and 18 on the A2H254-16 can be

configured as standard 10/100/1000BASE-T switch ports, using the command “set switch

stackport <ethernet | stack>” when the unit is in standalone mode (not stacked).
