Troubleshooting Using LEDs

For system alerts of levels 3-5, you clear the attention condition on the LED by accessing the logs using the SL
command available in the iLO MP command mode.
The fault condition for system alerts of level 7 is cleared by resolving the problem and cycling power. See the
SL error logs for additional error information.
NOTE Always check the iLO MP status logs in the case of a blinking yellow or red system LED before
replacing any hardware.
LAN LEDs
The front panel LAN LED indicates the system is communicating over the Gigabit:
• Blinking green: The system is communicating over the LAN; the LAN is active.
• Not green: No LAN cable attached; LAN network dead or the system is off or LAN link is established; no
current LAN activity.
Table 5-4 lists the 10/100/1000 base-T Ethernet LAN connectors LEDs.
Blinking green Booting or running BCH.
Blinking yellow (1/sec.) Attention:
Alerts of levels 3-5 detected in the iLO MP logs
The LED will turn off once the event log has been read.
Blinking red (2/sec.) Fault:
System Alert 7 detected, LED will blink until the problem is resolved
and the system boots successfully
Fatal hardware error detected by BMC, LED will blink until problem is
corrected.
