Steps for Merging a Split-Star Topology and a Star
Topology to Create a Tri-Star Topology
Figure 4-12 shows the cluster after the upgrade. The cluster switches from the star
topology have been reconfigured as X3 and Y3 in order to construct the new tri-star
topology. The upgraded cluster uses 1-kilometer two-lane links.
Steps for Merging a Split-Star Topology and a Star Topology to
Create a Tri-Star Topology
1. If you have not already done so, upgrade all nodes in all clusters to G06.13 or a
later G-series RVU by using the Steps for Upgrading Software With System Loads
to Obtain G06.14 Functionality on page 4-45.

Star Topology to Create a Tri-Star Topology
Note. The TSM Service Application shows Down-rev Firmware and Down-rev
Configuration alarms when the firmware or configuration running on a cluster switch are
older than the file versions of $SYSTEM.SYSnn.M6770 and $SYSTEM.SYSnn.M6770CL.
This situation is normal if you have upgraded a node but have not yet downloaded the new
firmware or configuration to the cluster switches.
