Replacing the TN799C C-LAN circuit pack
If you need to replace the TN799C C-LAN circuit pack:
1. Remove the TN799C Control-LAN (C-LAN) circuit pack.
2. Place the circuit pack in an antistatic carrier or bag. You might need to reinstall this circuit
pack if you must stop the migration.
3. Insert the new TN799DP C-LAN circuit pack into the same slot.
4. Replace the 259A adapter and CAT3 cable on the connector panel.
5. Use the Amphenol adapter that you used for the TN799 circuit pack and a CAT5 cable.
Installing TN771 Maintenance/Test circuit pack
You must replace the TN798 or the TN2402 circuit pack with a TN771 Maintenance/Test circuit
pack. Each location must have one TN771 Maintenance/Test circuit pack.
To install the TN771 Maintenance/Test circuit pack:
● Install the TN771 circuit pack in slot 1.
This carrier does not have a dedicated slot for the TN775 Maintenance (EPN) circuit pack.
Connecting to the media server
To connect to the media server:
1. Connect one end of the green CAT5 straight-through cable to the Ethernet switch on the
customer network.
2. Connect the other end of the cable to the IPSI adapter on the back of the media gateway.
