Stacking In a Star Topology
In this case, the DGS-3324SRi is the Master Switch in a star topology and up to six slave switches can be stacked with
Master Stackable Switch. Check the following examples as a reference guide.
For examples, we can:
• Make a star stack consisting of one DGS-3324SRi (Master), six DXS-3350SRs (no modules). Our switch count
would equal 6 + 1 and our token cost would equal twenty-six (2 + 24 = 26 ≤ 32). Success!
• Make a star stack consisting of one DGS-3324SRi (Master), one DGS-3324SR, two DXS-3326GSRs (no
modules), three DXS-3350SRs (one with module). Our switch count would equal 6 + 1 and our token cost
would equal twenty-two (2 + 2 + 4 + 14 = 22 ≤ 32). Success!
From these examples, we can see that there is a myriad of combinations possible for adding switches and modules to a
given stack. Yet, keep in mind three very important points in configuring the stack:
1. The total Token Cost of switches stacked must not exceed 32.
2. The total switch count of switches stacked in a ring topology cannot exceed 12.
3. The total switch count of switches stacked in a star topology cannot exceed 6 + 1.
NOTE: The total token cost of switches in a switch stack cannot exceed
32. Surpassing this token cost limitation will result in failure of the Switch
stack and render the switches in it inoperable.
