Troubleshooting Hardware Components
Corrective Action
Typically, the router boots from the
internal compact flash. If you
configured your router to boot from
an alternative boot device, ignore this
alarm condition.
If you did not configure the router to
boot from an alternative boot device,
contact JTAC. (See "Requesting
Technical Support" on page xxii.)
Replace the failed PIM. (See
"Replacing a PIM" on page 120)
Reformat the compact flash and
install a bootable image. (See the
JUNOS Software Administration Guide.)
If this remedy fails, you must replace
the failed Routing Engine. To contact
JTAC, see "Requesting Technical
Support" on page xxii.
Check the room temperature.
(See "Router Environmental
Tolerances" on page 66.)
Check the air flow. (See "General
Site Guidelines" on page 63.)
Check the fans. If you must
replace a fan or the Routing
Engine, contact JTAC. (See
"Requesting Technical
Support" on page xxii.)
If the router has an air filter,
check the filter and replace it if
it appears clogged. (See
"Replacing Air Filters on J2350
Routers" on page 153or
"Replacing Air Filters on J4350
and J6350 Routers" on page 154.)
Replace the failed fan. To contact
JTAC, see "Requesting Technical
Support" on page xxii.
