Serial Terminal Communication To Bmc Or Drac; Spcr Table - Dell External OEMR 1435 User Manual

Serial Terminal Communication to BMC or DRAC

Serial Terminal Mode allows you to directly connect to the BMC or DRAC
using a serial port connection and execute text-based commands. Refer to the
Appendix B for information about configuring your BMC and DRAC for Serial
Terminal Communication as well as available Terminal Mode Commands.
In Terminal Mode, the BMC or the DRAC, if present, support Escape key
sequences that allow switching between the Serial Terminal Connection and
the connection to the system COM2 port. This can be combined with the
Console Redirection via COM2 (see "Console Redirection Via COM2") to
switch between viewing the system console redirection and communicating
to BMC or DRAC to execute the terminal commands such as system reset.
NOTE:
For this combined functionality, Serial Communication baud rate and the
SOL baud rate must be set to the same value.
When in terminal mode, to switch the connection to the system COM2 port
use:
<Esc> +<Shift> <q>
When connected to the system COM2 port, to go back to the terminal mode
use:
<Esc> +<Shift> <9>

SPCR Table

The Serial Port Console Redirection (SPCR) table provides information about
how the system firmware and service processor use the out-of-band (OOB)
management port. For example, if the OOB Management port is a serial port,
the SPCR table contains information such as serial port number, baud terminal
type, and other settings used for OOB communication. The SPCR table is read
by the Special Administrative Console (SAC) for console redirection and
configures itself automatically during a bootable CD installation.
The SPCR table is automatically enabled if the system service processor
supports Emergency Management Services (EMS) such as console redirection.
If it is not configured automatically, you must configure SPCR to match BMC
settings by adding the following parameters to the unattend.txt file.
NOTE:
The unattend.txt file is automatically created after installation.
