NOTE: The ALARM LED on the Services Router is a single color alarm regardless
of the severity of the alarm condition (critical, major, or minor). When an alarm
condition triggers the LED, you see the yellow light turn on.
Table 199 describes alarms that can occur for a chassis component such as
the Routing Engine or a Physical Interface Module (PIM).

Alarm Conditions
The Services Router boots
from an alternative boot
device—the removable
compact flash disk or the
USB drive.
Typically, the router boots
from the primary compact
flash disk. If you configured
your router to boot from
an alternative boot device,
ignore this alarm condition.
A PIM has failed.
When a PIM fails, it attempts
to reboot. If the Routing
Engine detects that a PIM is
rebooting too often, it shuts
down the PIM.
Replacing and Troubleshooting Hardware Components
Remedy
If you did not configure
the router to boot from
an alternative boot
device, contact JTAC.
(See "Contacting the
Juniper Networks Technical
Assistance Center" on page
538.)
Replace the failed PIM. (See
"Replacing a PIM" on page
