Privilege Level Limit
This is the maximum privilege level that users can have on this channel. It restricts users of the
channel to a set of BMC commands that can be issued at that privilege level. For example, if
the channel privilege limit is configured with a maximum privilege level of Operator, and a user
is configured to have Administrator privilege, that user can still only execute Operator level
commands over this channel. See the LAN Channel Configuration Sub-task, on page 53 for a
description of the privilege levels.
IPMI Messaging Communication Settings
These parameters are the global settings for IPMI messaging, which include Direct Connect and
Modem modes. IPMI messaging always occurs with 8 bits/character, no parity, and 1 stop bit.
The COM settings that can be configured are:
• Flow Control: This option sets how the flow of data is controlled. Available choices are
No Flow Control, CTS/RTS (hardware handshake), and XON/XOFF.
• Baud Rate: This option sets the maximum rate in bits per second at which the data can be
transmitted through the serial port. Available baud rates are 9600, 19200, 38400,
57600, and 115200 bps. Support for baud rates higher than 19200 is optional and SMU
will only display those that the BMC supports.
• Enable Data Terminal Ready (DTR) Hang-up: When DTR Hang-up is enabled, hang-up
of a modem connection is based on when the DTR signal becomes inactive. When this is
enabled, the modem settings Modem Hang-up and Escape Sequences are not used.
Modem Mode Configuration
If Modem Mode is chosen as the connection mode in Serial/Modem Channel Configuration
screen and you click Next, the Modem Mode Configuration screen is displayed. This mode is
for applications that connect to the server via an external modem. The Modem Mode
Configuration screen is displayed below.
Figure 38. Modem Mode Configuration
After completing this screen, click Next to move to the next screen to continue this sub-task.
Modem Init String
Enter the ASCII string used to initialize the modem. This string is typically set to
ATE1Q0V1X4&D2&C1S0=0. The string can be up to 64 ASCII characters long, including the
termination character. The BMC automatically follows this string with an <Enter> character
or carriage return.
