Updated Resolution section with instructions to reset iLO.
Supersedes ES041112_CW01 (Revision 0).

Data transfer to any ProLiant server through the Serial COM port may stop when the Command Line Interface feature of Integrated Lights-Out (iLO) is enabled. Serial port communication will become unresponsive and no data will be transmitted or received by the host server through the serial COM port when the Command Line Interface (CLI) is enabled.

When iLO firmware is configured for the CLI to be enabled, it will monitor data being sent through the serial COM port to the host server. If the transmitted data matches the ASCII character string "ESC-SHFT-9," the iLO CLI will be invoked and the firmware will switch the DB9 connector from the system Universal Asynchronous Receiver Transmitter (UART) to the iLO UART. All further incoming serial COM port data is directed to iLO instead of the host server.

Note: This event is rare and the likelihood of occurrence is small.

SCOPE

Any ProLiant server configured with the Integrated Lights-Out (iLO) Firmware Version 1.60 (or later).

A list of ProLiant servers with the iLO management feature is maintained at the following URL:

RESOLUTION

For continuous data transfer through the Serial COM port, use the procedures provided below to reset iLO:

Power on the server.

  1. Browse to the Integrated Lights-Out (iLO) Web-based interface IP address using a Web browser.
  2. Login to Integrated Lights-Out (iLO).
  3. Click on the Administration tab.
  4. Click on the Network Settings link in the left side frame.
  5. Click on the Apply button at the bottom of the Network Settings web page.
  6. iLO will reset and the COM port will release.

The CLI feature can be disabled in version iLO Firmware 1.60 (or later). The latest iLO Firmware can be downloaded from the HP Lights-Out Products Software and Drivers web site located at the following URL:
