Chapter 6. Configuring the switch module
The switch module has an internal Ethernet path to the management module, eight external CEE
ports, eight external FC ports, one external management port, and a serial console port. The switch
module supports two remote-access modes for management through Ethernet connections. You
can select the mode that is best suited for your BladeCenter environment.
• Default mode: The default mode uses the internal path to the management module only. In
this mode, the remote-access link to the management console must be attached to the
Ethernet connector on the management module. The Internet protocol (IP) addresses and
SNMP parameters of the switch modules can be automatically assigned by the IBM Director
BladeCenter Deployment wizard (when available), or you must assign them through the
BladeCenter Management and Configuration Program. This mode enables you to provide a
secure LAN for management of the BladeCenter subsystems that is separate from the data
network. See
“Establishing a TCP/IP session through the management module” on page 28 for
more information.
• Remote management mode: You can enable remote management of the switch module
through the external ports, instead of or in addition to access through the management
module. This mode can be enabled only through the management module configuration
interface. When this mode is enabled, the external SFP+ ports support both management
traffic and BladeCenter application data traffic. This mode enables the use of additional switch
module IP addresses on different IP subnets than the management modules. This is useful
when the switch modules are to be managed and controlled as part of the overall network
infrastructure, while secure management of other BladeCenter subsystems is maintained
through the management module. See
“Enabling management through external ports” on
page 29 for additional instructions about configuring the switch module for this mode of
operation.
The mini-USB console port provides an alternative path to manage and configure the switch for
local access.
Important:
• Before you configure the switch module, make sure that the management modules in the
BladeCenter unit are correctly configured. For more information about configuring the switch
module, see the following documents:
- Installation and User’s Guide for the BladeCenter unit
- BladeCenter Advanced Management Module Installation Guide or BladeCenter T
Advanced Management Module Installation Guide
- IBM BladeCenter Advanced Management Module User’s Guide
• When installed in high-speed slots 7/8, the default IP address of the switch module is
10.90.90.80. When installed in high-speed slots 9/10, the default IP address of the switch
module is 10.90.90.81.
• If you change the IP address of the switch module from the AMM. and restart the switch, it will
maintain this new IP address as its default value.
• The management module and the switch module can communicate with each other only if they
are on the same IP subnet.
