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
• Password: console, Web, Telnet, SNMP (including DM)
• Stack operational mode
• SNMP community strings
Stack configurations
As shown in Figure 14 , the cascade connectors and cables on the BayStack
400-ST1 Cascade Module front panel provide the ability to stack up to 8 switches.
With BPS-2000 MDAs installed in each switch, the stack can accommodate a
maximum of 224 switch ports.
Because stack parameters are associated with the base unit (see “Base unit ”), the
physical stack order depends on the base unit’s position and whether the stack is
configured
stack up or stack down.
Stack up configurations
In Figure 14 , data flows from the base unit (unit 1) to the next switch, which is
assigned as unit 2, and continues until the last switch in the stack is assigned as
unit 8. The physical order of the switches is
from bottom to top (unit 1 to unit 8).
