Caution: The B2G124-24, B2G124-48 and B2H124-48 are not PoE-compliant devices.

Do not connect a SecureStack C2 PoE Redundant Power System (C2RPS-POE) to the

power connector. Otherwise, damage to the device may result.

Precaución: Los dispositivos B2G124-24, B2G124-48 y B2H124-48 no cumplen con el

estándar PoE (power over ethernet). No conecte una fuente de poder redundante (RPS)

SecureStack C2 PoE (C2RPS-POE) al cable de corriente. De lo contrario, el dispositivo

puede dañarse.

Note: The Mini-GBIC ports cannot be active simultaneously with their corresponding

10/100/1000BASE-T ports. For example, if SFP port 24 establishes a link first on the

B2G124-24, the 10/100/1000BASE-T built-in RJ45 port 24 is not available and vice-versa.
