Resetting the Stack with Management
If you install an optional Management Module, its reset button resets the entire
stack of hubs. The hubs are reconfigured and counters are reset to zero. This
can also be done through the ASCII console or HP AdvanceStack Assistant.
From the ASCII console, you can also change the hub back to its default
settings. The default settings are all ports enabled, security violations cleared,
and all ports are placed back on segment 1.
The rest of the management features are described in chapter 3.
Redundant Management in a Stack
Two Management Modules in a stack provide you with redundant manage-
ment so that if one module fails, the other module will take over. To identify
the hub with the Management Module acting as primary, the Active LED is lit
on the Management Module. After you install the second Management Module,
you should specify which one is primary through the ASCII console or through
HP AdvanceStack Assistant. (If you do not select a module, the module with
the lowest MAC address is active.).
If the second Management Module takes over because the first one failed, see
chapter 5, “Troubleshooting.”
Active Management Module (has lowest MAC address so Active
