The TGM550 firmware version must be compatible with the JUNOS software version installed on the Services Router. For compatibility information, see the Communication Manager Software & Firmware Compatibility Matrix at http://support.avaya.com.
 |
Caution: If the TGM550 firmware version is not compatible with the JUNOS software version on the router, the router does not detect the VoIP interface (vp-pim/0/0) and the interface is unavailable. For more information, see TGM550 Is Installed But the VoIP Interface Is Unavailable. |
If you are upgrading both the TGM550 firmware and the JUNOS software on the router, first upgrade the TGM550 firmware, and then upgrade the JUNOS software.
For information about upgrading JUNOS software, see the J-series Services Router Administration Guide. For information about upgrading the TGM550 firmware, see the Administration Guide and CLI Reference for the Avaya IG550 Integrated Gateway.
