Using iLO 2 127
iLO 2 control of ProLiant BL p-Class server LEDs
iLO 2 can monitor BL p-Class servers through POST tracking and the Server Health LED.
Server POST tracking
Feedback is limited while the server is booting because of the headless nature of the ProLiant BL p-Class
servers. iLO 2 provides boot-time feedback by flashing the Server Health LED green during server POST.
The LED is set to solid amber if the boot is unsuccessful. The LED is set to solid green at the end of a
successful boot.
After a successful boot, control of the Server Health LED is returned to the server, which can turn the LED
off or set it to some other color to represent the health of the server hardware.
Insufficient power notification
iLO 2 turns the Server Health LED solid red if iLO 2 cannot power on the server because insufficient power
is in the rack infrastructure.
ProLiant BL p-Class alert forwarding
iLO 2 supports blade infrastructure SNMP traps on a pass-through basis. Reporting of blade infrastructure
status by iLO 2 does not require operating system support. The alerts (traps) originate from the Enclosure
Manager and Power Supply Manager and are transmitted to iLO 2. iLO 2 p-Class firmware forwards
infrastructure alerts as SNMP traps to a correctly configured management console. These alerts allow the
monitoring of p-Class alerts to take place in an SNMP management console.
p-Class alert forwarding is disabled by default and can be enabled from the SNMP/Insight Manage
Settings web page.
The following alerts are identified and forwarded by iLO 2:
Alert ID Description
22005 Enclosure temperature failure
22006 Enclosure temperature degradation
22007 Enclosure temperature OK
22008 Enclosure fan failed
22009 Enclosure fan degraded
22010 Enclosure fan OK
22013 Rack power failure
22014 Rack power degraded
22015 Rack power supply OK
22023 Rack server failed; not enough power
