Corrective Action
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.
If you did not configure the router to
boot from an alternative boot device,
contact JTAC. (See "Requesting
Support" on page xxi.)
Replace the failed PIM. (See
"Replacing a PIM" on page 164.)
Reformat the compact flash and
install a bootable image. (See the
J-series Services Router Administration
Guide.)
If this remedy fails, you must replace
the failed Routing Engine. To contact
JTAC, see "Requesting Support" on
page xxi.
Check the room temperature.
(See "Router Environmental
Tolerances" on page 87.)
Check the air flow. (See
"General Site Guidelines" on
page 85.)
Check the fans. (See "J2300
Cooling System" on page 19
or "J4300 and J6300 Cooling
System" on page 32.) If you
must replace a fan or the
Routing Engine, contact JTAC.
(See "Requesting Support"
on page xxi.)
Replace the failed fan. To contact
JTAC, see "Requesting Support" on
page xxi.
