Step 3. Connect the other end of the SFP+ cable into the SFP+, XG3 or XG4 port of your
switch.
Note: In this example, the cable is connected to XG3 port of the switch.
Step 4. Repeat Steps 2 to 3 to the remaining switches.
You should now have connected your switches according to your desired topology.

Master Selection Process
The master unit is selected from the master-enabled units (1 or 2). The factors in selecting
the master unit are taken into account in the following priority:
System Up Time — The master-enabled units exchange up-time, which is measured in
segments of 10 minutes. The unit with the higher number of segments is selected. If both units
have the same number of time segments, and the unit ID of one of the units was set manually
while the unit ID of the other was set automatically, the unit with the manually-defined unit ID
is selected; otherwise the unit with the lowest unit ID is selected. If both units IDs are the
same, the unit with the lowest MAC address is chosen.
Note: The up time of the backup unit is retained when it is selected as master in the switch
failover process.
Unit ID — If both units have the same number of time segments, the unit with the lowest unit
ID is selected.
MAC Address — If both units IDs are the same, the unit with the lowest MAC address is
chosen.
Note: For a stack to operate, it must have a master unit. A master unit is defined as the
active unit that assumes the master role. The stack must contain a Unit 1 and/or Unit 2 after
the master selection process. Otherwise, the stack and all its units are partially shut down,
not as a complete power-off, but with traffic-passing capabilities halted.
Follow these steps to configure stack settings on the Master switch:
Step 1. Log in to the web-based utility of your switch then choose Administration > Stack
Management.
