Troubleshooting problems
If you suspect problems with a newly installed mixed stack configuration, start
troubleshooting by verifying the following items:
• A Business Policy Switch is designated as the base unit.
• All other units in the stack have the base unit select switch set to Off.
• The Business Policy Switch’s operational mode is set to Hybrid Stack, and the
unit has been reset after changing the operational mode (Figure 130).
• All units in the stack exhibit the same ISVN.
• All units must be reset when you add a Business Policy Switch to an existing
BayStack 450 and 410 switch stack.
• All Business Policy Switches have the same software version. Similarly, all
BayStack 450 and BayStack 410 switches are operating with updated and
compatible software.
• When the stack is powered up, ensure that the Cas Up and Cas Dwn (cascade)
and Base LEDs are green (steady, not blinking).
