Using the serial interface
Use the serial interface to:
v Observe firmware progress.
v Run the SMS Utility program
v Access the Linux terminal in order to configure Linux.
You can connect a PC serially through the BladeCenter unit using a specific UART
cable. To connect to the serial console, plug the serial cable into the BladeCenter
unit and connect the other end to a serial device or computer with a serial port. For
more information, see the Installation and User's Guide for your BladeCenter unit.
Set the following parameters for the serial connection on the terminal client:
v 115200 baud
v 8 data bits
v No parity
v One stop bit
v No flow control
By default, the blade server sends output over SOL and to the serial port on the
BladeCenter unit. However, the default for input is to use SOL. If you wish to use a
device connected to the serial port for input you must press any key on that device
while the blade server boots.
Using the SMS utility program
The Advanced Management Module is the main means of administering the
BladeCenter unit and the blade servers. However, another utility is provided which
in some cases can give more information than that displayed in the Advanced
Management Module. This is the System Management Services (SMS) utility
program.
The SMS utility program allows you to view and update the VPD, change the boot
list and set network parameters.
Starting SMS
Complete the following steps to start SMS:
1. Using a Telnet or SSH client, connect to the Advanced Management Module
2. When prompted, enter a valid user ID and password. The default management
3. Power cycle the blade server and start an SOL console session by using the
external Ethernet interface IP address.
module user ID is USERID, and the default password is PASSW0RD, where the
0 is a zero.
Note: The user ID and password may have been changed. If so, check with the
system administrator for a valid id and password.
power -cycle -c command.
For example, to power cycle and start an SOL remote text console with a blade
server that is in the first bay of the BladeCenter unit, issue the command:
power -cycle -c -T system:blade[1]
To open a console session with a blade that is already powered on, use the
command:
console -T system:blade[1]
