Cabling G650 Media Gateways

To cable two G650 media gateways together;

1. If not already removed, remove the fan assemblies from media gateways A and B.

2. Remove the right TDM/LAN bus terminator from media gateway A, and install he bus terminator at the left end of the TDM/LAN bus on media gateway B. Make sure to install the TDM/LAN bus terminators with the arrow on the back pointing upward.

3. Loosen the nuts on the posts of the plate covering the bottom right TDM/LAN cable routing slot of media gateway B and remove the plate.

4. Remove the right slot cover on top of medi a gateway A and the lower-right slot cover of media gateway B to open the slots. 5. Pull open the EMI Gasket, and pass the TDM/ LAN bus cable through the routing slots in both media gateways. Push the free end of the EMI Gasket back in place. Make sure the open corner of the gasket faces the rear of the media gateway. Once installed, the top media gateway rests on and compresses the gasket.

6. Install the lower connector of the TDM/LAN bus cable on right end of TDM/LAN bus in media gateway A. ** Make sure the arrows on the back of the cable terminators point upward.**

7. Install the upper connector of the TDM/LAN bus cable on the right end of the TDM/LAN bus in media gateway B. ** Make sure the TDM/LAN bus cable is installed on the right hand side, connecting gateway A to B. It should be on the right hand side of both gateways. This is critical to ensure proper operation of the duplicated IPSI boards.**

8. Flip over the routing slot plates and reinstall both. Once the plates are reinstalled, the ends of the routing slots are covered.

9. If finished, reinstall the fan assemblies and tight en the 7 screws. All knurled screws must be tightened securely so that they cannot be loosened without the use of a tool.

  • username root password ******* access-type admin (****** being your new password)

Update Supplied by John Waber

First, this “super secret” password ONLY works if you physically connect to the Services Port on the Media Gateway; for obvious security reasons it does not work across a LAN connection.

Second, starting with firmware version 36.5.0, Avaya removed this “backdoor” login capability as it is considered a security risk.

If you cannot remember the login password, you have three possible solutions:

1. Use the Alternate Software Boot bank (ASB) button to boot from a previous firmware load. Hopefully, the other firmware load has a known password, or is a version earlier than 36.5.0

2. Contact Avaya and create a service request so an Avaya associate can reset the lost password using an Avaya ASG protected services login.

3. Use the “nvram init” jumper on the motherboard to wipe out the entire configuration. Note that this voids any Avaya warranties on the device. Remove power to the device. Open the MG case. Locate the jumper labeled J3801. Move the bridge to pins 2-3. Connect the power cable and wait 5 minutes. Remove power. Move the bridge back to original position. Connect power and hope the MG is returned to a factory default configuration.
