Juniper Networks J-series Services Router J2320 - Manual (Page 44)

Table 9: J2320 and J2350 ALARM LED
Description State Color
Major alarm indicates a critical situation on the router that
has resulted from one of the following conditions. A red
alarm condition requires immediate action:
■ One or more hardware components have failed.
■ One or more hardware components have exceeded
temperature thresholds.
■ An alarm condition configured on an interface has
triggered a critical warning.
On steadily Red
Minor alarm condition requires monitoring or maintenance:
■ Indicates a noncritical condition on the router that, if
left unchecked, might cause an interruption in service
or degradation in performance.
■ A missing rescue configuration or software license
generates an amber system alarm.
On steadily Yellow
No alarms. Off Unlit
For information about alarm conditions and corrective actions, see “Chassis Alarm
Conditions” on page 209. For additional information, see the J-series Services Router
Administration Guide.
HA LED
The HA (high availability) LED is for future use. The LED lights when the router starts,
but otherwise remains unlit.
RESET CONFIG Button
Use the RESET CONFIG button to return the router to either the rescue configuration
or the factory default configuration. The button is recessed to prevent it from being
pressed accidentally. To press this button insert a small probe (such as a straightened
paper clip) into the pinhole on the front panel (see Figure 8 on page 19 and
Figure 9 on page 19).
For example, if someone inadvertently commits a configuration that denies
management access to a Services Router, you can delete the invalid configuration
and replace it with a rescue configuration by pressing the
RESET CONFIG button. You
must have previously set the rescue configuration through the J-Web interface or the
CLI. The rescue configuration is a previously committed, valid configuration.
CAUTION: Pressing and holding the RESET CONFIG button for 15 seconds or
more—until the STATUS LED blinks red—deletes all configurations on the router,
including the backup configurations and rescue configuration, and loads and commits
the factory configuration.
