Using the serial interface Use the serial interface to: v Observe firmware progress. 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 documentation that comes with 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 BladeCenter 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 external Ethernet interface IP address. 2. When prompted, enter a valid user ID and password. The default management 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. 3. Power cycle the blade server and start an SOL console session by using the 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 server that is already powered on, use the command: console -T system:blade[1] Chapter 5.

v
Access
the

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
documentation
that
comes
with
your
BladeCenter
unit.
Set
the
following
parameters
for
the

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
BladeCenter
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
external
Ethernet
interface
IP
address.
2.
When
prompted,
enter
a
valid
user
ID
and
password.
The
default
management
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.
3.
Power
cycle
the
blade
server
and
start
an
SOL
console
session
by
using
the
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
server
that
is
already
powered
on,
use
the
command:
console
