Troubleshooting Tips
RS-232 connection: If a dumb terminal / PC running terminal emulation software is attached to
the iLO 2 MP “local” port and does not respond to a Control-B CR key sequence (and the terminal
is running 9600 baud, 8 data bits, is ONLINE, and so on), it is possible that the iLO 2 MP is not
operational / functional. See
“Management Subsystem (iLO 2 MP/BMC)” (page 167)
for the
following LED locations:
•
The iLO 2 MP’s Heartbeat LED
•
The BMC’s Heartbeat LED
Replace core I/O board FRU if both Heartbeat LEDs are not flashing green; suspect bulk power
supplies, or midplane board FRU, or I/O backplane board FRU if both Heartbeat LEDs are off.
LAN connections: See
“I/O Subsystem (SAS/SATA/SCSI/DVD/HDD/Core I/O)” (page 168)
for
iLO 2 MP LAN LED states.
Environment
Ambient intake air temperature is often different from ambient room temperature; you should
measure the operating temperature and humidity directly in front of the cabinet cooling air intakes,
rather than measure only ambient room conditions.
Within the server, temperature sensors report chassis temperature to the BMC. The BMC controls
fan speed, based on this information.
Temperature sensors are found on the display panel, where a thermal sensor detects the ambient
room temperature. This sensor’s reading is the main parameter used to regulate fan speed, under
normal conditions
