Joining stacks
You can join two stacks, whether entirely BPS 2000 units, or mixed units. You do
not have to renumber the units in either stack.
To join two existing stacks:
1
Designate one stack as the one to join the other stack.
2 Reset the stack that will join the other stack to factory defaults.
3
Turn off the power to the all units in the stack that will join the other stack by
unplugging the power cords from each unit.
a On the unit that was the Base Unit of this stack, use the Unit Select switch
to deselect it as the Base Unit.
b
Redo all the cabling so that all units will work as one stack.
4 Power-up the newly joined units by plugging in the power cords.
It may take a few minutes for the entire stack to display on the console. All units
will show as their new numbers within the newly joined stack.
Note: Once you begin the upgrading process, do not interrupt the
process at all. Interrupting the downloading (or upgrading) process may
cause loss of connectivity.
