Severity
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.

Yellow
Craft interface The craft interface failed. Replace the failed craft
interface.
Red
Fan trays One fan tray was removed from
the chassis.
Install the missing fan tray. Yellow
Two or more fan trays were
removed from the chassis.
Install the missing fan trays. Red
One fan in the chassis is not
spinning or is spinning below
required speed.
Replace the fan tray. Red
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.
Replace the failed FPC. Red
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.
