Power Source Interruptions
Table 8.7 shows how the FastIron chassis protects against power surges and power drops.
Mean Time Between Failure
Table 8.8 lists the Mean Time Between Failure (MTBF) for the FastIron X Series chassis devices and modules.
The MTBF is the average estimated time, in units of hours, before a hardware failure may occur.
Table 8.7: Chassis Power Surge and Drop Protection
Property Protection Mechanism
Power surge MOV and Spark Gap protection
Power drop An AC loss of >15ms will cause the
power supply to shut down due to
input under-voltage
