Port board replacement

You can add or replace Intel Dialogic port boards in a customer-provided MAS as described in this section.

Note: The number of port boards you can install in the MAS varies depending on the MAS, the type of switch integration, and the number of PCI slots available. These instructions assume that up to six PCI slots are available in the MAS, and that board installation starts with the 6th PCI slot. Modify these instructions as appropriate for your MAS.

To replace or add a Dialogic port board:

1. Prepare for server maintenance
2. Remove the old port board.
3. Cycle power on the server, then set jumpers and switches.
4. Install the new port board.
5. Verify new card operation.

Prepare for server maintenance

Before you replace port cards in an MAS:

1. If the server is already in operation, you must take the server out of service to install port boards. Schedule and publicize a time.
2. Verify that the replacement equipment is on site and appears to be in usable condition, with no obvious shipping damage.

Caution! If you are adding or replacing a Dialogic port board, verify that the new board is of the same type as any port boards already installed. You cannot mix board types within the same MAS, such as analog boards with DSE or QSIG.

3. Verify that the replacement board is of the same type as the board you are replacing.

Note: New QSIG port boards have a single connector. The early E1-QSIG and T1-QSIG port boards have two connectors, with a plug in the unused connector on the faceplate. Both types of QSIG boards operate identically.

4. For a system that has multiple MASs, you can busyout the ports on the switch, if possible, before you start the repair operation. The PBX administrator must use the procedures appropriate for this PBX to busyout the ports for MAS. Depending on the switch integration, the administrator might be able to temporarily reroute calls to other MASs. Otherwise, callers into the system might hear ring-no answer or a busy signal.

Remove the old port board

To remove a faulty port board:

1. Shut down the system software and power off the server.
2. Unplug the AC power cord for safety reasons.
3. Remove any exterior cables connected to the port board you want to replace.
4. Open the chassis to access the card slots.
   
5. Remove any interior cables connected to the port board you want to replace. For example, a Computer Telephony (CT) bus cable is present if more than one port board is installed.
6. Unscrew the retaining screw that attaches the port board to the chassis. Set it aside.
7. Lift the port board out. See figure Replacing or adding a port board.

Cycle power, then set jumpers and switches

For Dialogic port boards, you must first cycle power on the server to clear out the old settings.

Caution! If you do not cycle power on the empty server, the system might not recognize the new board. If the system retains the old settings, you might have to remove all the port boards, reboot the empty server, then reinstall all port boards. You must then manually reconfigure all port boards to correct the problem.

To cycle server power, and then set jumpers and switches on the port board for board position, bus termination, and other features:

1. Cycle power on the MAS to clear out the settings for the faulty board:
   1. Leave the cover off. Plug in the cables for the monitor, keyboard, and mouse.
   2. Plug in the AC power cord. Let the server boot completely.
   3. After the reboot is complete, shut down the server software. Click Start > Shut Down, and then click OK.
   4. After the server turns off, unplug all cables from the back of the server.
2. Remove the new port board from its packaging.
3. Set the jumpers and switches as required for this type of board:
• D/120JCT-LS or D/41JCT-LS analog boards
• D/82JCT-U or D/82JCT-U-PCI-UNIV digital set emulation (DSE) boards
• D/480JCT-1T1 QSIG or D/600JCT-1E1 QSIG boards

Note: Compare the settings on the old port board and the replacement port board. Ensure that the new port board uses the correct settings.

4. Install the new port board as follows:
   • If you are replacing an existing card, install the replacement card in the same slot from which you removed the old port board.
   • If you are adding a new card, install the port board in the next available PCI slot. Add port boards in the PCI slots starting from the outer edge of the chassis towards the center of the MAS.

Install the new port board

To install a new port board:

1. Slide the card edge connector into the slot connector and the card slot retainer bracket into the slot guide.
2. Apply pressure to the top of the card only, until the edge connector is firmly seated. See figure Replacing or adding a port board.
3. Replace and tighten the retaining screw to hold the port board in place.
4. If multiple port boards are installed, use the Computer Telephony (CT) bus cable to connect the port boards. To attach the bus cable:
1. Position the CT bus cable so the colored stripe on the ribbon cable faces towards the ports at the back of the chassis.
2. Attach the end connector on the bus cable to the CT bus edge connector at the top of the board in the slot closest to the side of the chassis.
3. Connect the next bus connector to the next port board, and so on.
4. If the cable has extra connectors or loose ribbon cable, tuck the cable down so it does not snag when you replace the cover.
5. Close the chassis.
6. Reattach any exterior cables. For more information, see Installation and Upgrades (pdf).
7. Restore power to the server.

Verify new port board operation

To verify that the new port board is working:

1. After the server boots, configure the new board. For more information, see Installation and Upgrades (pdf).

Note: If you reseat or replace a Dialogic board, you might need to reconfigure all Dialogic boards in the server. Verify the settings for all the port boards using the Dialogic Configuration Manager after you install, reseat, or replace a Dialogic board.

2. If you added a port board to an MAS, connect the new port board to the PBX (switch) and administer it.
3. If the PBX administrator busied out the MAS ports on the switch, the administrator must now bring the MAS ports back into service.
4. Test the Dialogic port board using the Dialogic Line Test application. For more information, see Installation and Upgrades (pdf).
5. Verify that any port board alarms are resolved. For more information, see Displaying the MAS alarm logs.
