Changing the compression card IP address The IP address and communications firmware that is stored on the compression card in the blade workstation is used for communication with the thin client only. All blade workstation compression cards have Dynamic Host Configuration Protocol (DHCP) enabled by default. If you are using DHCP on the network, DHCP assigns an IP address dynamically. If you configure the compression card to disable DHCP, the compression card uses the static network configuration. The compression card has the following default static network configuration: IP address: Subnet: Gateway: 192.168.100.1 255.255.255.0 192.168.100.254 To avoid network conflicts, you must use DHCP or change the default static IP address to a unique IP address for each blade workstation compression card. You also must create a unique IP address for each thin client. Important: v Whether you use DHCP or use the static IP address, set the IP address of only one compression card at a time, with only one new blade workstation on the network at a time. v I/O modules 1 and 2 on the BladeCenter unit must be Ethernet-capable. If DHCP is enabled, the compression card automatically obtains its IP address from a DHCP server. The card then attempts to discover a DNS server, so that it can register itself with a connection manager or connection broker for connection to the thin client. For a description of the registration process, see the documentation that comes with the connection broker software that you purchased. Note: The compression card DNS Discovery Prefix factory setting is ws-broker. If DHCP is not enabled, you can change the compression card static IP address in either of two ways: v Using the blade workstation Configuration/Setup Utility program. See "Using the Configuration/Setup Utility program to change the compression card IP address". v Using a computer, such as a notebook computer, on the same subnet and gateway as the blade workstation, and logging in to the blade workstation. You can connect the computer to the network or directly to the Ethernet-capable I/O module 2. See "Using another computer to change the compression card IP address" on page 29. Using the Configuration/Setup Utility program to change the compression card IP address To change the blade workstation compression card IP address through the Configuration/Setup Utility program, complete the following steps: 1. Turn on the blade workstation. 2. Immediately give the blade workstation control of the BladeCenter unit shared keyboard, video, and mouse ports. 3. At the prompt, press F1 to initiate the Configuration/Setup Utility program. 4. On the Configuration/Setup Utility program main menu, click Advanced Setup → Compression Card Network Configuration. 28 BladeCenter HC10 Type 7996: Installation and User's Guide

Changing
the
compression
card
IP
address
The
IP
address
and
communications
firmware
that
is
stored
on
the
compression
card
in
the
blade
workstation
is
used
for
communication
with
the
thin
client
only.
All
blade
workstation
compression
cards
have
Dynamic
Host
Configuration
Protocol
(DHCP)
enabled
by
default.
If
you
are
using
DHCP
on
the
network,
DHCP
assigns
an
IP
address
dynamically.
If
you
configure
the
compression
card
to
disable
DHCP,
the
compression
card
uses
the
static
network
configuration.
The
compression
card
has
the
following
default
static
network
configuration:
IP
address:
192.168.100.1
Subnet:
255.255.255.0
Gateway:
192.168.100.254
To
avoid
network
conflicts,
you
must
use
DHCP
or
change
the
default
static
IP
address
to
a
unique
IP
address
for
each
blade
workstation
compression
card.
You
also
must
create
a
unique
IP
address
for
each
thin
client.
Important:
v
Whether
you
use
DHCP
or
use
the
static
IP
address,
set
the
IP
address
of
only
one
compression
card
at
a
time,
with
only
one
new
blade
workstation
on
the
network
at
a
time.
v
I/O
modules
1
and
2
on
the
BladeCenter
unit
must
be
Ethernet-capable.
If
DHCP
is
enabled,
the
compression
card
automatically
obtains
its
IP
address
from
a
DHCP
server.
The
card
then
attempts
to
discover
a
DNS
server,
so
that
it
can
register
itself
with
a
connection
manager
or
connection
broker
for
connection
to
the
thin
client.
For
a
description
of
the
registration
process,
see
the
documentation
that
comes
with
the
connection
broker
software
that
you
purchased.
Note:
The
compression
card
DNS
Discovery
Prefix
factory
setting
is
ws-broker
.
If
DHCP
is
not
enabled,
you
can
change
the
compression
card
static
IP
address
in
either
of
two
ways:
v
Using
the
blade
workstation
Configuration/Setup
Utility
program.
See
“Using
the
Configuration/Setup
Utility
program
to
change
the
compression
card
IP
address”.
v
Using
a
computer,
such
as
a
notebook
computer,
on
the
same
subnet
and
gateway
as
the
blade
workstation,
and
logging
in
to
the
blade
workstation.
You
can
connect
the
computer
to
the
network
or
directly
to
the
Ethernet-capable
I/O
module
2.
See
“Using
another
computer
to
change
the
compression
card
IP
address”
on
page
29.
