Conditions for Replacing a Module

Replace a Remote Annex with another module of the same type under
any of the following conditions:
If the annunciator on the module front panel remains off,
indicating that the module is not receiving +5 volt power or
that the power level is below the reset limit (4.65 volts) when
other modules in the hub are receiving normal operating
power. For more information, see
If the annunciator remains amber, indicating that some
portion of the module has failed and a check of the self-test
messages indicates that the problem cannot be fixed. For
more information, see
Module Configuration Management
Each module installed in a Model 5000 chassis operates according to
software parameter values and hardware option settings. You can use
these to customize module operation for that particular hub. This
combination of software and hardware values is the module
configuration, of which there are actually two types:
"Primary" configuration, which is the set of base values built
into the module at the time it is manufactured. A user cannot
change this configuration.
"Default" configuration, which is the permanent
configuration plus any changes to jumper or switch settings.
The default configuration is valid for any hub slot at any
time. Each module must have a default configuration. This
configuration is stored in two places: on the module itself
and on the supervisory module. You can change this
configuration through a network management module
(NMM) or through a terminal connected to the chassis
service port.
