Power Source Interruptions
Table 6.4 shows how the FastIron GS protects against power surges and power drops.
Mean Time Between Failure
Table 6.5 lists the Mean Time Between Failure (MTBF) for the FastIron GS and the 10-GbE uplink modules. The
MTBF is the average estimated time, in units of hours, before a hardware failure may occur.

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
