3. Choose the appropriate firmware package from the choices available on the HP Support
Center web page at http://www.hp.com/go/bizsupport. If a new version of the
firmware is available, download it and save it to CD, or copy it over the network to the system
you are updating.

Troubleshooting the system console

All system console connections (VGA, USB, local RS-232 and iLO 3 MP LAN) are located on the
rear panel of the server.
HP-UX uses the RS-232 serial text connection to a terminal or terminal emulator software to control
server operations locally.
HP-UX alternatively uses the iLO 3 LAN connection over a network to control server operations
locally through telnet or Secure Shell, and remotely over a network through web GUI.
The Windows operating systems uses the VGA (monitor) and USB (keyboard and mouse) connections
to control server operations locally.

Troubleshooting tips

RS-232 connection: If a dumb terminal / PC running terminal emulation software is attached to the
iLO 3 MP "local" port and does not respond to a Ctrl-B-enter key sequence (and the terminal is
running 9600 baud, 8 data bits, is ONLINE, etc.) then it is possible that the iLO 3 MP is not
operational / functional. See
LED locations:
The iLO 3 MP heartbeat LED
The BMC heartbeat LED
Replace system board CRU if both heartbeat LEDs are not flashing green; suspect bulk power
supplies, or I/O backplane CRU if both heartbeat LEDs are off.
LAN connection: See

Troubleshooting the server 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 server temperature to the iLO, which controls fan
speed, based on this information.
Temperature sensors are found on:
Display panel, where a thermal sensor detects the ambient room temperature. This sensor
reading is the main parameter used to regulate fan speed, under normal conditions.
Section provides environmental specifications for the server:
