Understanding LED Environmental Indications

The LEDs can indicate two alarm types: major and minor. Major alarms indicate a critical problem that
could lead to the system being shut down. Minor alarms are for informational purposes only, giving you
notice of a problem that could turn critical if corrective action is not taken.
When the system has an alarm (major or minor), that indicates an overtemperature condition, the alarm
is not canceled nor is any action taken (such as module reset or shutdown) for 5 minutes. If the
temperature falls 5°C (41°F) below the alarm threshold during this period, the alarm is canceled.

LED red Generates syslog message and an SNMP trap.
If there is a redundancy situation, the system
switches to a redundant supervisor engine and the
active supervisor engine shuts down.
If there is no redundancy situation and the
overtemperature condition is not corrected, the
system shuts down after 5 minutes.

If a major alarm is generated and the
overtemperature condition is not corrected, the
system shuts down after 5 minutes.
Monitors the condition if a minor alarm is generated.
