management LAN. This section describes the management LAN when the
LPAR manager functionality is used.
• Connect the MGMT1 port of the management LAN module to the
management LAN.
• Connect the MGMT1 port of the standby management LAN module to the
management LAN in case a failure occurs in the active management
module or management LAN module.
• Connect the network device used by LPAR manager for management

When the management module and server blade BMC requests IP
address, they send their hostnames to the DHCP server. You can
check the hostnames in the logs of the DHCP server to know which IP
address is assigned to those modules. The default hostname is a
string like the following.
Management module:
323GG-RE4xxxxxx-Yxxxxxxxx
Server blade BMC:
323GG-RV3xxxxxxxx-Yxxxxxxxx
Use the serial port of the management module to log in to CLI console
and run show mgmt-module mgmt-lan and show blade mgmt-lan
commands to show the IP addresses.
