Automatic failover
The automatic failover is a temporary safeguard only. If the stack loses power or is
reset, the temporary base unit will not power up as the base unit when power is
restored. For this reason, you should always assign the temporary base unit (assign
another Business Policy Switch, if available) as the base unit (set the Unit Select
switch to Base) until the failed unit is repaired or replaced. When a failure of the
base unit is discovered, the Unit Select switch on the temporary base unit should
be set to Base.
For detailed information about temporary base units, see Installing the BayStack
400-ST1 Cascade Module .
Note:
If you do not reassign the temporary base unit as the new base
unit, and the temporary base unit fails, the next unit directly downstream
from this unit becomes the new temporary base unit. This process can
continue until there are only two units left in the stack configuration.
