Power
z
The AC-Powered G8124 has dual load-sharing internal power modules, 50 - 60 Hz, 100 - 240
z
VAC auto-switching per module.
The nominal power for the G8124 ranges from 115 W to 168 W depending on the speed of the
z
port (1G/10G), type of transceivers (SR or DAC), and number of active ports.
Mean time between failures (MTBF): 189,060 hrs with ambient operating temperature of 40ºC MTBF
z
is calculated using the Telcordia Technologies Reliability Prediction Procedure for Electronic
Equipment (SR-332 issue 2), Parts Count (method 1 case 1) failure rate data.
