In a Managed System
In a managed MSH chassis, operation of the Switch 1005 is the same,
but the Management Module may itself override the link settings. This
will occur if:
■
The Management Module has a stored configuration for a Switch 1005
in that slot, and the stored backplane settings are different from the set
on the Switch 1005
■
The Management Module derives default backplane settings that are
different from the set on the Switch 1005
If the Management Module has no stored configuration data for the
Switch 1005, it will apply the following default backplane settings:
■
the first Switch 1005 detected in the chassis will have all backplane
ports enabled.
■
subsequent Switch 1005 modules will have only the Fast Ethernet
backplane enabled.
To ensure that the Management Module can see and configure new
Switch 1005 modules correctly when they are inserted, you must insert
them when the MSH chassis and Management Module are powered on.
