5. Power down the system and move the Rolling BIOS jumper back to cover pins 2 - 3. 6. Replace the system cover, plug in the system, and boot it. The system boots from the newly flashed image and a known-good backup image remains in the other bank. Console Redirection The BIOS supports keyboard and video redirection through a serial link (COM port). When console redirection is enabled, local (host server) keyboard input and video output are passed to both the local keyboard and video connections and to the remote console through the serial link. Keyboard inputs from both sources are valid and video is displayed to both outputs. With console redirection, the system can be operated without a host keyboard or monitor and run entirely from a remote console. Setup and any other text-based utilities can be accessed through console redirection. Serial Configuration Settings When redirecting through a modem instead of through a null modem cable, the modem needs to be configured with: • Auto-answer (Example: ATS0=2, to answer after two rings). • Modem reaction to DTR set to return to command state (Example: AT&D1). Failure to provide this results in the modem dropping the link when the server reboots, with AT&D0, or becoming unresponsive to server baud rate changes, with AT&D2). • Handshaking must be set to RTS/CTS + CD (carrier detect) for optimum performance. Handshaking must be set to Xon/Xoff + CD if the emergency management port (EMP) shares the COM port with serial redirection. With 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. • Both the EMP and console redirection require N, 8, 1 mode (no parity, 8-bit data, 1 stop bit). The BIOS does not require that the splash logo be turned off for console redirection to function. The BIOS supports multiple consoles, some of which are in graphics mode and some in text mode. The graphics consoles can display the logo while the text consoles receive the redirected text. Console redirection ends at the beginning of the Legacy OS boot (INT 19h). 46 Intel® Server System S7000FC4UR Product Guide

Power down the system and move the Rolling BIOS jumper back to cover pins
2 - 3.
6.
Replace the system cover, plug in the system, and boot it. The system boots from

Console Redirection
The BIOS supports keyboard and video redirection through a serial link (COM port).
When console redirection is enabled, local (host server) keyboard input and video output
are passed to both the local keyboard and video connections and to the remote console
through the serial link. Keyboard inputs from both sources are valid and video is displayed
to both outputs.
With console redirection, the system can be operated without a host keyboard or monitor
and run entirely from a remote console. Setup and any other text-based utilities can be
accessed through console redirection.
Serial Configuration Settings
When redirecting through a modem instead of through a null modem cable, the modem
needs to be configured with:
•
Auto-answer (Example: ATS0=2, to answer after two rings).
•
Modem reaction to DTR set to return to command state (Example: AT&D1). Failure
to provide this results in the modem dropping the link when the server reboots, with
AT&D0, or becoming unresponsive to server baud rate changes, with AT&D2).
•
Handshaking must be set to RTS/CTS + CD (carrier detect) for optimum
performance.
Handshaking must be set to Xon/Xoff + CD if the emergency management port
(EMP) shares the COM port with serial redirection. With 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.
•
Both the EMP and console redirection require N, 8, 1 mode (no parity, 8-bit data, 1
stop bit).
The BIOS does not require that the splash logo be turned off for console redirection to
function. The BIOS supports multiple consoles, some of which are in graphics mode and
some in text mode. The graphics consoles can display the logo while the text consoles
receive the redirected text.
Console redirection ends at the beginning of the Legacy OS boot (INT 19h).
