Caution: The A2H124-24FX 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.

Note: The 1000BASE-T built-in RJ45 stacking ports 25 and 26 on the A2H124-24FX 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).
