Using the Business Policy Switch 2000 Version 1.2
Temporary base unit
In a mixed stack containing only one Business Policy Switch
If there is only one Business Policy Switch in your mixed stack configuration and
it fails, the next upstream BayStack 410 or BayStack 450 switch from the failed
base unit will become the temporary base unit and will continue stack operation.
The base unit change is indicated by the base LED on the temporary base unit’s
LED display panel turning on (amber).

If the stack’s base unit reverts to a BayStack 410 or BayStack 450 switch, the
stack does not maintain Business Policy Switch features and will continue
operation as a BayStack 410 or BayStack 450 stack.

In a mixed stack containing more than one Business Policy Switch
If the assigned Business Policy Switch base unit fails, the next Business Policy
Switch unit in the stack order automatically becomes the new temporary base unit.
All Business Policy Switch units in the stack will be exhausted as base units,
successively, before assigning a BayStack 410 or BayStack 450 as base unit. The
base unit change is indicated by the base LED on the temporary base unit’s LED
display panel turning on (amber).

Compatible software versions
Be sure to follow the instructions for the initial setup according to the Installing
the Business Policy Switch 2000 guide.
the Business Policy Switch 2000 guide.
In a mixed stack, the BayStack 450 and BayStack 410 switches must use
compatible, but device specific, software versions to operate with the Business
Policy Switch. You must ensure that the Interoperability Software Version
Numbers (ISVN) are identical. That is, the ISVN number for the BayStack 450
switch and BayStack 410 switch must have the same ISVN as the Business Policy
Switch. If they are not the same, the stack does not operate.
