Once DHCP has initially allocated hosts addresses, it is recommended to copy these into the pre-
assigned list so the same IP address will be reallocated in the event of a reboot.
3.6.3 Configure Management Switch for Failover or Broadband OoB
The Management Switch in the B096-048/016 Console Server can be configured to provide a failover
option. In the event of a problem using the main LAN connection for accessing the Console Server, an
alternate access path is used.
By default, the failover is not enabled. To enable, select the Network page on the System: IP
menu
Now select the Failover Interface to be used in the event of an outage on the main network.
This can be:
o an alternate broadband Ethernet connection or
o the B096-048/016 internal modem or
o an external serial modem/ISDN device connected to the B096-048/016 console port (for
out-dialing to an ISP or the remote management office)
Click Apply. You have selected the failover method. However, it is not active until you have
specified the external sites to be probed to trigger failover and set up the failover ports
themselves. This is covered in Chapter 5.
Note The second Ethernet port on the B096-048/016 can be configured as either a Management LAN
gateway port or it can be configured as an OoB/Failover port - but not both. So ensure you did
not configure this port as the Management LAN
on the System: IP menu
