Table 28: M40 Router Chassis Component Alarm Conditions (continued)
Chassis
Component Alarm Condition
Alternative media The router boots from an
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
the required speed.
FPC An FPC has an out-of-range
or invalid temperature
reading.
An FPC microcode download
has failed.
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.
Too many hard errors in FPC
memory.
Too many soft errors in FPC
memory.
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.
