SuperStack II Hub 10 Management Module 1-15
DUA1663-0BAA03
A stack can consist of up to eight units linked together with hub
expansion cables (3C625). A stack behaves as a single Ethernet
repeater. Only one Management Module or Advanced RMON Module is
needed to manage the stack.
I f your stack consists of mixed units, the LinkBuilder FMS, 10BTi and
10BT units may ONLY occupy positions 2 through 4.
The Management Module or Advanced RMON Module should be
installed in the top or bottom unit. The unit with the module installed
is always designated unit 1 in the stack, the next connected unit is unit
2, and so on. The M odule records configuration information (such as
resilient link settings) for all the units in the stack.
S ome SNMP network management applications assume that unit 1 is at
the top of the stack. If you install the module in the bottom unit, the
stack may be depicted by the application in reverse order to the actual
arrangement of units.
The narrower FMS units, if used, should be positioned at the top of the
stack.
If you have a stack containing both a LinkBuilder 10BTi unit and a
Hub 10 unit fitted with a M odule, the M odule will manage the stack.
The management facilities of the 10BTi unit will be disabled.
