HP Integrity rx3600 Server User Service Guide

headless mode, with the iLO 2 MP as its headless console device, and the VGA as its graphics
console.
Troubleshooting the Server Interface
RS-232 connection: A dumb terminal or 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, and is ONLINE. The solution is that the iLO 2 MP is not operational
or functional. Examine the following LEDs:
• iLO 2 MP heartbeat LED
• BMC heartbeat LED
Replace the core I/O board FRU if both heartbeat LEDs are not flashing green. If both heartbeat
LEDs are off, check the power supplies, midplane board FRU, and I/O backplane board FRU.
LAN Connection Problems: See “I/O Subsystem ” (page 155). To locate these LEDs, see
“Management Subsystem ” (page 154).
Environment
Ambient intake air temperature is often different from ambient room temperature. Measure the
operating temperature and humidity directly in front of the cabinet cooling air intakes in addition
to 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.
