Supported Hardware and Software
This section describes the supported platforms and minimum software release required to use the interface cards with the router.
Upgrading the Router Software
Registered Cisco.com users can download the latest software for the router from the following link:
http://software.cisco.com/download/navigator.htmlFor instructions on how to upgrade the router operating software, refer to Upgrading to a New Release in the Cisco IOS Cross-Platform Release Notes.
Finding the Software Version and Feature Set
To determine the router software version, refer to Determining Your Software Version in the Cisco IOS Cross-Platform Release Notes.
New Software Features
For information about all new features available in the current interface card software release, refer to the Cisco IOS Cross-Platform Release Notes.

Tip This document must be used with the appropriate Cisco IOS Cross-Platform Release Notes for the interface card. This document includes only the information and caveats that are specific to using the interface cards on supported routers. The cross-platform release notes contain complete information and list of caveats for the software release supported on the router and the interface cards.
Limitations and Restrictions
This section only outlines known limitations for the interfaces cards noted. Some features might not work as documented, and some features could be affected by recent changes to hardware or software.
![]()
Note For all known limitations for the software releases that support the interface cards, refer to the appropriate Cisco IOS Cross-Platform Release Notes for the interface card (see software links in New Software Features).
Connected Grid 4-Port Serial GRWICs
The interface cables for the Connected Grid 4-Port Serial GRWICs are rated for -4 degrees F (-20 degrees C) to 167 degrees F (75 degrees C).
Connected Grid DSL GRWICs
The Connected Grid ADSL/ADSL2/ADSL2+/VDSL2 (Annexes A, B, and M) GRWICs require a firmware update as noted below.
VDSL Firmware Upgrade Required
Upgrade the VDSL firmware version on the Connected Grid ADSL/ADSL2/ADSL2+/VDSL2 (Annexes A, B, and M) GRWICs to A2pv6C035j by doing the following:
1.
Download the VDSL firmware file from Cisco.com or TAC Support:
http://www.cisco.com/cisco/software/release.html?mdfid=283122091&flowid=&softwareid=282821780&os=null&release=A2pv6C035j&relind=null&rellifecycle=null&reltype=null
2.
Copy the new firmware into router flash and rename it as vdsl.bin .
The router automatically references the new VDSL firmware during boot-up.
4.
To verify that the new firmware is in use, enter the show controller vdsl command.
Connected Grid 2G/3G/4G Multimode LTE Interface Card
This section outlines the following topics for the interface card:
Operational Limitations
- Cellular networks support only outgoing calls on the interface card. The interface card cannot receive calls over the cellular network.
- The throughput rate on the interface card varies, and is affected by:
Required Scripts
You must download, install, and execute the scripts described in this section to use the CG LTE interface card with the CGR 2010 and Cisco IOS Release 15.1(4)M4. The scripts address the following known issues that can occur with the interface card:
- Access Point Name (APN) —To use the interface card on Verizon cellular networks, the interface card APN must be changed. Cisco provides a script to automate the APN change for the interface card 3G and 4G wireless profiles. For detailed information about this issue, and how the script resolves the issue, refer to the documentation bundled with the scripts.
- LTE Modem Out-of-Sync State —In some cases, the card’s cellular interface appears to be up, but no longer sends or receives data. Cisco provides a script that configures Embedded Event Manager (EEM) on the router to automatically recover the interface when this issue occurs. For detailed information about this issue, and how the script resolves the issue, refer to the documentation bundled with the scripts. The section Open Caveats lists the bug ID numbers for this issue.
Downloading the Scripts and Supporting Documents
Download the scripts from the Cisco Software Download Center with this link:
www.cisco.com/cisco/software/release.html?mdfid=281295442&flowid=6999&softwareid=284194160&release=SCRIPTS_V1.0&relind=AVAILABLE&rellifecycle=&reltype=latest
Documentation for the scripts is bundled with the software download, and includes instructions for installing, configuring, and executing the scripts on the router.
Open Caveats
This section lists the open caveats for the interface cards.
![]()
Note For additional open caveats for the Cisco IOS releases that support the interface cards, refer to the
New Software Features section for the appropriate software release.
Connected Grid 2G/3G/4G Multimode LTE Interface Card
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.
Resolved Caveats
This section lists the resolved caveats for the interface cards.
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: This issue is resolved in Cisco IOS Release 15.2M&T. In earlier releases, there is no workaround.
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: This issue is resolved in Cisco IOS Release 15.2M&T when operating with 3.5.x firmware and SDK v1.8.0 from vendor. In earlier releases, there is no workaround.
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: This issue is resolved in Cisco IOS Release 15.2M&T when operating with 3.5.x firmware and SDK v1.8.0 from vendor. In earlier releases, there is no workaround.
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: This issue is resolved in Cisco IOS Release 15.2M&T. In earlier releases, there is no workaround.
