Configuring Serial Port Sharing

By default, the service processor (SP) controls the serial management (SER MGT) port and
uses it to redirect the host serial console output. Using Oracle ILOM, you can assign the host
console (COM1) as owner of the SER MGT port output, which allows the host console to
output information directly to the SER MGT port. Serial port sharing is useful for Windows
kernel debugging, because you can view non-ASCII character traffic output from the host
console.
Set up the network on the SP before attempting to change the serial port owner to the host
server. If the network is not set up first, and you switch the serial port owner to the host
server, you cannot connect using the CLI or web interface to change the serial port owner
back to the SP. To return the serial port owner setting to the SP, restore access to the serial
port on the server. For details, refer to the Oracle Integrated Lights Out Manager (ILOM) 5.0
Documentation Library at https://www.oracle.com/goto/ilom/docs.
If you accidentally lose access to Oracle ILOM, contact Oracle Service and follow the process
to return the serial port ownership back to the SP.
42 Oracle Server X8-2L Service Manual • January 2021
Description
The server has two power supply connectors, one for each power supply.
Do not attach power cables to the power supplies until you finish connecting
the data cables to the server. The server goes into Standby power mode, and
the Oracle ILOM service processor initializes when the AC power cables are
connected to the power source. System messages might be lost after 60 seconds
if the server is not connected to a terminal, PC, or workstation.
Note - Oracle ILOM signals a fault on any installed power supply that is not
connected to an AC power source, since it might indicate a loss of redundancy.
The service processor NET MGT port is the optional connection to the Oracle
ILOM service processor. The NET MGT port is configured by default to use
Dynamic Host Configuration Protocol (DHCP). The service processor NET
MGT port uses an RJ-45 cable for a 10/100/1000BASE-T connection.
The Ethernet port enables you to connect the system to the network. The
Ethernet port uses an RJ-45 cable for a 10/100/1000BASE-T connection.
The USB port supports hot-plugging. You can connect and disconnect a USB
cable or a peripheral device while the server is running without affecting
system operations.
The service processor SER MGT port uses an RJ-45 cable and terminal (or
emulator) to provide access to the Oracle ILOM command-line interface (CLI).
Using Oracle ILOM, you can configure it to connect to the system console.
Note - This port does not support network connections.
