Mean Time Between Failure
Table 16 lists the Mean Time Between Failure (MTBF) for the FastIron GS, FastIron GS-STK, and 10
Gbps uplink modules. The MTBF is the average estimated time, in hours, before a hardware failure
may occur.
Power draw specifications
Table 17 lists the typical and maximum power draw specifications for FGS and FGS-STK models.
TABLE 15 Device Power Surge and Drop Protection
Property Protection Mechanism
Power surge MOV and Spark Gap protection
Power drop (<=1 second) An AC loss of >15ms will cause the power supply to shut
down due to input under-voltage
Maximum power draw 96 watts with 2-port 10-Gigabit uplinks
82 watts without 2-port 10-Gigabit uplinks
