Chapter 5. Setting up Serial over LAN for the HC10 blade workstation Serial over LAN (SOL) provides a means of managing the blade workstation remotely by using a command-line interface (CLI) over a Telnet or Secure Shell (SSH) connection. SOL provides console redirection for both BIOS and the blade workstation operating system. The SOL feature redirects serial-connection data over a LAN without the need for special cabling. The SOL connection enables the blade workstation to be managed from any remote location that has network access. SOL has the following advantages: v Remote administration without keyboard, video, or mouse v Reduced cabling and no need for a serial concentrator v A standard Telnet interface that eliminates the need for special client software The IBM BladeCenter management-module command-line interfaces provide access to the text-console command prompt on each blade workstation through a SOL connection, enabling the blade workstation to be managed from a remote location. Hardware and firmware requirements The blade workstation is SOL capable. You must configure the blade workstation to enable SOL operation. The blade workstation supports SOL sessions on VLAN 4095 only; make sure to configure the SOL function to operate on VLAN 4095. Hardware requirements For the HC10 Type 7996 blade workstation, SOL uses the Ethernet 1 network interface (Planar Ethernet) and an Ethernet I/O module in the BladeCenter unit I/O bay 1 to communicate. Software requirements Make sure that you are using the latest versions of device drivers, firmware, and BIOS code for the blade workstation, advanced management module, and other BladeCenter components (see the minimum version levels in "Firmware updates" on page 36). Go to http://www.ibm.com/systems/support/ for the latest information about upgrading the device drivers, firmware, and BIOS for BladeCenter components. The latest instructions are in the documentation that comes with the updates. General configuration This section provides instructions for configuring the blade workstation to operate using SOL, where that information differs from the information in the BladeCenter Serial over LAN Setup Guide. The BladeCenter Serial over LAN Setup Guide is on the IBM BladeCenter Documentation CD that comes with the blade workstation. You can also download the latest version of the guide from http://www.ibm.com/systems/ support/. © Copyright IBM Corp. 2007 39

Setting
up
Serial
over
LAN
for
the
HC10
blade
workstation
Serial
over
LAN
(SOL)
provides
a
means
of
managing
the
blade
workstation
remotely
by
using
a
command-line
interface
(CLI)
over
a
Telnet
or
Secure
Shell
(SSH)
connection.
SOL
provides
console
redirection
for
both
BIOS
and
the
blade
workstation
operating
system.
The
SOL
feature
redirects
serial-connection
data
over
a
LAN
without
the
need
for
special
cabling.
The
SOL
connection
enables
the
blade
workstation
to
be
managed
from
any
remote
location
that
has
network
access.
SOL
has
the
following
advantages:
v
Remote
administration
without
keyboard,
video,
or
mouse
v
Reduced
cabling
and
no
need
for
a
serial
concentrator
v
A
standard
Telnet
interface
that
eliminates
the
need
for
special
client
software
The
IBM
BladeCenter
management-module
command-line
interfaces
provide
access
to
the
text-console
command
prompt
on
each
blade
workstation
through
a
SOL
connection,
enabling
the
blade
workstation
to
be
managed
from
a
remote
location.
Hardware
and
firmware
requirements
The
blade
workstation
is
SOL
capable.
You
must
configure
the
blade
workstation
to
enable
SOL
operation.
The
blade
workstation
supports
SOL
sessions
on
VLAN
4095
only;
make
sure
to
configure
the
SOL
function
to
operate
on
VLAN
4095.
Hardware
requirements
For
the
HC10
Type
7996
blade
workstation,
SOL
uses
the
Ethernet
1
network
interface
(Planar
Ethernet)
and
an
Ethernet
I/O
module
in
the
BladeCenter
unit
I/O
bay
1
to
communicate.
Software
requirements
Make
sure
that
you
are
using
the
latest
versions
of
device
drivers,
firmware,
and
BIOS
code
for
the
blade
workstation,
advanced
management
module,
and
other
BladeCenter
components
(see
the
minimum
version
levels
in
“Firmware
updates”
on
page
36).
Go
to
for
the
latest
information
about
upgrading
the
device
drivers,
firmware,
and
BIOS
for
BladeCenter
components.
The
latest
instructions
are
in
the
documentation
that
comes
with
the
updates.
General
configuration
This
section
provides
instructions
for
configuring
the
blade
workstation
to
operate
using
SOL,
where
that
information
differs
from
the
information
in
the
BladeCenter
Serial
over
LAN
Setup
Guide
.
The
BladeCenter
Serial
over
LAN
Setup
Guide
is
on
the
IBM
BladeCenter
Documentation
CD
that
comes
with
the
blade
workstation.
You
can
also
download
the
latest
version
of
the
guide
from
