Locally

Follow these steps to locally boot the server to the service partition:

1. Restart the managed server.

2. Monitor the boot process and press <F2> when prompted to enter BIOS setup.

3. Arrow to the System Management menu, and select Enabled for the Service Boot option.

4. Press <F10> to save the setting and exit out of the BIOS setup. The system automatically

reboots to the Service Partition.

Console Redirection

The BIOS supports redirection of video output and keyboard input via serial link. This section

details the serial redirection scheme. For redirection over LAN (Serial over LAN or SOL), see the

online help available in ISM.

When console redirection is enabled, local (host server) keyboard input and video output are passed

both to the local keyboard and video connections, and to the remote console via the serial link.

Keyboard inputs from both sources are considered valid and video is displayed to both outputs.

With console redirection, you can operate the server system without having a keyboard or monitor

attached to it. Setup and any other text-based utilities can be accessed via console redirection.

Note that serial redirection uses PC-ANSI and the UART settings assume 1 stop bit.

Operation

When redirecting through a modem, as opposed to a null modem cable, the modem needs to be

configured as follows:

• Auto-answer (for example, ATS0=2, to answer after two rings).

• Modem reaction to DTR set to return to command state (such as AT&D1). Failure to provide

the modem reaction results in the modem either dropping the link when the server reboots (as

in AT&D0) or becoming unresponsive to server baud rate changes (as in AT&D2).

• The Setup/EMP option for handshaking must be set to CTS/RTS + CD for optimum

performance. The CD refers to carrier detect. If the EMP is sharing the COM port with serial

redirection, the handshaking must be set to CTS/RTS+ CD. In selecting this form of

handshaking, the server is prevented from sending video updates to a modem that is not

connected to a remote modem. If this is not selected, video update data being sent to the

modem inhibits many modems from answering an incoming call. An EMP option utilizing CD

should not be used if a modem is not used and the CD is not connected.

Once console redirection is selected via Setup, redirection binary is loaded into memory and

activated during POST. While redirection cannot be removed without rebooting, it can be inhibited

and restarted.
