Using the BayStack 410-24T 10BASE-T Switch
•Temporary Base Unit
If an assigned base unit fails, the next unit in the stack order automatically becomes the new temporary base unit, as follows:
If the assigned base unit is a Business Policy Switch (in a mixed stack configuration), the next Business Policy Switch unit in the stack order automatically becomes the new temporary base unit.
If there is only one Business Policy Switch unit in your mixed stack configuration, and it fails, the next upstream BayStack 450 Switch 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 (yellow).
•Automatic failover
The automatic failover to a temporary base unit is a temporary safeguard only. If the stack configuration loses power, 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 as the designated base unit (assign another Business Policy Switch, if available) until the failed unit is repaired or replaced. Set the Unit Select switch on the temporary base unit to Base (up = Base) to reassign it as the new base unit.
•Removing a unit from the stack
If a unit is removed from the stack (therefore operating in standalone mode), the following switch configuration settings revert back to the settings configured before the unit became a member of the stack:
-IP address
-Console password
-TELNET password
-SNMP community strings
