IBM manual Nortel 10 Gigabit Uplink Ethernet Switch Module Installation Guide

vThe default IP address of the GbE switch module is 192.168.70.127, 192.168.70.128, 192.168.70.129, or 192.168.70.130, depending on the switch module bay where it is installed.

vIf you change the IP address of the GbE switch module and restart the BladeCenter unit, the GbE switch module maintains this new IP address as its default value.

vThe management module and the GbE switch module can communicate with each other only if they are on the same IP subnet.

vWhen you use the management-module Web interface to update the switch-module configuration, the management-module firmware saves the new configuration in its internal nonvolatile random-access memory (NVRAM). If the GbE switch module restarts, the management module applies the saved configuration to the GbE switch module.

If the GbE switch module restarts and the management module cannot apply the saved configuration, the GbE switch module defaults to using the configuration that it had previously saved. If the IP subnet address of the GbE switch module does not match the IP subnet address of the management module, you can no longer manage the GbE switch module from the management module.

vFor switch communication with a remote management station, such as the IBM Director server, through the management-module external Ethernet port, the switch-module internal-network interface and the management-module internal and external interfaces must be on the same IP subnet.

See the documentation listed in the “Related documentation” on page 2 for specific details about configuring the GbE switch module and preparing for system installation.
