11.9 How Do I Remove/Insert Mediant 1000 Modules Via
SNMP
The FRU (Field Replace Unit) via SNMP:
¾ To replace a module using SNMP:
1. Remove the module, by performing the following:
a. Set the acSysModuleFRUaction with fruOutOfServiceAction(2), where the
instance refers to the corresponding module.
b. Check that the action succeeds by performing a Get of the value of
acSysModuleFRUstatus with the same instance. The value should be
moduleOutOfService(3.)
c. There is no need to stop the trunks before setting the module to OutOfService.
But, if one of the trunks on the module provides the clock (assuming that TDM
Bus Clock Source = network and TDM Bus PSTN Auto Clock = disable), then you
cannot remove this module. Therefore, before removing the module, you must
change the clock reference to a trunk on a different module. The last digital
module can always be removed even if it provides the clock reference.
2. Insert a module, by performing the following:
a. Set the acSysModuleFRUaction with fruBackToServiceAction(3), where the
instance refers to the corresponding module.
b. Check that the action succeeds by performing a Get of the value of
acSysModuleFRUstatus, with the same instance. The value should be
moduleExistOk(2).
11.10 How Do I View PSTN Alarms Via SNMP
¾ To view PSTN alarms, using SNMP:
The acTrunkStatusEntry table can be used to view the color and status (steady or
blinking) of the E1/T1 LEDs that are located on the front panel of the device.
The dsx1LineStatus table can be used to view Line Status of the interface. It contains
loop back, failure, received alarm and transmitted alarms information.
The AcDChannelStatus trap is sent to indicate a D-channel alarm.
11.11 How Do I Work with Row-Status
Generally, when working with Row-Status there are two modes:
One-Shot mode - the EMS provides all information within one PDU and uses Create-
And-GO.
Dribble mode - the EMS must first send Create-And-Wait and thereafter the data.
Active SET must be sent at the end of the process. For example, to add a row to the
channelsEntry table (via a MIB browser), you need to perform the following:
a. Set the channelRowStatus; the window ‘Select Table Instance’ is opened.
