Connected Grid 2G/3G/4G Multimode LTE Interface Card
•
Symptom: The LTE LED is on (solid green) even if there is no cellular signal available. The LTE LED should be off when there is no available cellular signal.
Conditions: This issue occurs when interface card network connectivity is interrupted, for example when the antenna is removed from the interface card.
Workaround: There is no workaround for this issue.
•
Symptom: The cellular interface fails and the RSSI reports 125 dBm.
Conditions: This issue occurs when system remains in an idle state for several days, and then the cellular interface attempts to place a call.
Workaround: Enter the test cellular 0/x/0 modem-power-cycle EXEC command to resolve the issue. To prevent this issue, use the script described in Downloading the Scripts and Supporting Documents to configure Cisco Embedded Event Manager (EEM) to automatically recover the interface when it fails.
•
Symptom: The interface card modem resets, and the interface state changes from up to down. Data calls cannot be established after the interface state change.
Conditions: This issue occurs after a network outage or when the RSSI drops to -125 dBm or lower.
Workaround: Enter the test cellular 0/x/0 modem-power-cycle EXEC command to resolve the issue. To prevent this issue, use the script described in Downloading the Scripts and Supporting Documents to configure Cisco Embedded Event Manager (EEM) to automatically recover the interface when it fails.
•
Symptom: Firmware upgrade for the interface card modem fails.
Conditions: This issue occurs when attempting to upgrade the firmware with the microcode reload global configuration command.
Workaround: Use a third-party upgrade utility to upgrade the firmware over the interface card mini-USB port.
•
Symptom: In some cases the show cellular command output might show incorrect data. The Current Service Status might be displayed as "No Service." The value for Mobile Country Code (MCC) and Mobile Network Code (MNC) might be displayed as 0.
Conditions: This issue might occur after power cycling or resetting the router.
Workaround: There is no workaround for this issue.
