3-16 SPARC Enterprise Mx000 Servers XSCF User’s Guide December 2010
If an error occurs in the active XSCF Unit in the systems with two XSCF Units, XSCF
generates a failover, then the LAN of the other XSCF Unit can be used.
FIGURE 3-6 Example of LAN Port Connections Made Redundant
Using Two LAN Ports Selectively for Management and Maintenance
FIGURE 3-7 shows an example of a configuration where the two XSCF-LANs of one XSCF
Unit are used selectively for the system administrators and the FE. This configuration does
not make the XSCF-LAN redundant. The purpose is as follows:
One LAN is used for the system administrator.
The other LAN is used for the remote maintenance service only or by the FE.
