HP integrity rx2800 i4 User Manual

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
remotely through Secure Shell or through a web GUI.
NOTE: RS-232 connection: If a dummy terminal/PC running terminal emulation software is
attached to the iLO MP local port and does not respond to a CTRL-B key sequence then it is possible
that the iLO MP is not operational/functional.
Troubleshooting the server 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, rather than
measuring ambient room conditions only.
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.
See “Server physical and environmental specifications” (page 16) for server environmental
specifications.
