Table 27: M20 Router Chassis Component Alarm Conditions

Chassis
Component Alarm Condition
Alternative media The router boots from alternate
boot device: the hard disk.
Typically, the router boots from
the flash drive. If you configure
your router to boot from the
hard disk, ignore this alarm
condition.
Craft interface The craft interface failed.
Fan trays One fan tray was removed from
the chassis.
Two or more fan trays were
removed from the chassis.
One fan in the chassis is not
spinning or is spinning below
required speed.
FPC An FPC failed. If this occurs, the
FPC attempts to reboot. If the
SCB sees that an FPC is
rebooting too often, it shuts
down the FPC.
Hot swapping Too many hot-swap interrupts
are occurring. This message
generally indicates that a
hardware component that plugs
into the router's backplane from
the front (generally, an FPC) is
broken.
