EGMENTING
Segmenting the Hub
The hub can be segmented either via hardware with the front
panel switches (TA models) or buttons (all other models), or
via software with EliteView or any other SNMP-based manager.
Note: Unless the hardware lockout feature has been enabled
via software, the latest action (either hardware or soft-
ware) overrides the previous setting.
Each segment button has two positions: Enable ON and Enable
OFF. Each segment switch has three positions: Hub, Stack and
Isolate. The figure on the following page illustrates how these
buttons and switches can be used to segment the hubs. These
functions are defined in the table on the next page.
Model 3328T (bottom) contains four segment buttons. The
buttons for segments A and C are in the Enable OFF position,
so these segments are not isolated; they are connected to the
inter-repeater bus. The buttons for segments B and D are in
the Enable ON position, so these segments are removed or
isolated from the inter-repeater bus and from each other.
Model 3312TA (middle) contains two segment switches. The
switches for both segments are in the Hub position so these
segments are joined together to form a single 14-port segment.
Model 3326TA (top) contains four segment switches. The
switch for segment D is in the Stack position, so segment D is
connected to the stack through the inter-repeater bus. The
switch for segment C is in the Isolate position, so segment C is
removed from the inter-repeater bus. The switches for
segments A and B are in the Hub position, so these segments
are joined to form a 14-port segment.
