Hot Swapping of APMs
The T1 access unit allows you to insert and remove APM cards and their
matching I/O cards without powering down the unit or interrupting data on the
network or on other APMs. The T1 access unit automatically recognizes when an
APM is inserted or removed, and can display the configuration option settings
and MIB objects applicable to the APM that was inserted or removed.
NOTE:
You do not have access to screens and configuration options that are not
valid for the given configuration, nor can you preconfigure or predelete a
configuration for an APM prior to inserting it in the housing. To see
configuration options for an inserted APM, you must exit the configuration
screen, then reenter it.
APM Insertion
Insertion of an APM into a housing occurs under one of the following three
conditions.
If the slot previously . . . Then . . .
Was unassigned The configuration options for this new APM will be set to
factory defaults and will be accessible from the MIB and the
async terminal.
Contained the same type
of APM The existing configuration options will be used and will be
accessible from the MIB and the async terminal.
Contained a different type
of APM The system will generate a Module Misconfiguration alarm
and trap for the selected slot. The screens and field choices
applicable to this APM will not be displayed until you accept
the APM upon loading or saving a configuration, or via an
enterprise MIB. When you accept the new APM, the
previous APM’s configuration is deleted, the new APM’s
configuration options are set to factory defaults, and the
screens and field choices applicable to the new APM will be
displayed.
If you reject the APM, the configuration options for the
previous APM can be edited, but all other configuration
options and screens will not display fields or choices or MIB
objects applicable to either the previous or the current APM.
