Note: The Mini-GBIC ports cannot be active simultaneously with their corresponding
10/100/1000BASE-T ports. For example, if SFP port 48 establishes a link first on the
B2G124-48P, the 10/100/1000BASE-T built-in RJ45 port 48 is not available and
vice-versa.
Caution: The B2G124-48P and B2H124-48P 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 B2G124-48P y B2H124-48P 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.
