Ethernet switch module configuration planning
One Ethernet switch module or copper pass-thru module is required in switch
module bay 1 of your BladeCenter S chassis to enable communication between the
blade servers and an external Ethernet network.
You have the option of installing an addition Ethernet switch module in I/O
module bay 2. Remember that if you do, you will also need to install an Ethernet
expansion card option in each blade server that will access the external Ethernet
network through the switch module in I/O module bay 2.
There are several options to consider, depending on the Ethernet switch module
that you are installing:
v Switch settings
v
Port settings
v
SNMP
v
User accounts
v
TFTP
v
VLANs
Important: The default VLAN ID 4095 is used for internal communications
between the advanced management module and the blade servers. Do not
remove this VLAN.
v
Multicasting
v Mirroring
v
Spanning tree
v
Class of service
v
Link aggregation
v
Enable external ports for management
Refer to your specific Ethernet switch documentation for more information about
the various options. You can find the documentation for Ethernet switch modules
at the IBM Systems Information Center, which is at http://
publib.boulder.ibm.com/infocenter/systems/index.jsp. To access the I/O module
documentation from this site, click

To determine which Ethernet switch modules are compatible with the BladeCenter
S chassis, see the IBM ServerProven Web site at http://www.ibm.com/servers/
eserver/serverproven/compat/us/eserver.html.
Important: The BladeCenter S system ships with the external ports of the Ethernet
Switch module set to disabled . Before any communication with the ports is possible,
the ports must first be enabled through the advanced management module
