These release notes support the ptx®/SYNC V4.5.0 synchronous Wide Area Networking software, which is a prerequisite for all other ptx synchronous data communication products, such as ptx/SNA and ptx/X.25. This software works in conjunction with a Synchronous Communication Controller, or SCC, such as the SCC-P for the NUMA-Q® platform and the SCC-V (also referred to as the Data Communications Processor, or DCP) for the Symmetry® platform.
ptx/SYNC V4.5.0 requires DYNIX/ptx® V4.5.0 or later on a NUMA-Q or Symmetry system. ptx/SYNC is a requirement for ptx/SNA V4.6.0 or later and ptx/X.25 V4.5.0 or later.
ATTENTION On NUMA-Q systems, the sync board is the SBE PCI-360 Intelligent High-Speed Synchronous Serial Communications Adapter, or SCC-P. On Symmetry systems, the DCP board is the VMEbus Synchronous Communication Controller, or SCC-V.

To install ptx/SYNC, follow the instructions in the DYNIX/ptx V4.5.0 and Layered Product Software Installation Release Notes. Be sure to rebuild the kernel and reboot the system, as directed in the software installation release notes. It is recommended that the SCC board(s) be installed when the system is brought down to install the newly rebuilt kernel.
After installing the ptx/SYNC software and the SCC board(s), and before using ptx/SNA or ptx/X.25, set up the system, through ptx/ADMIN®, to automatically download the necessary firmware module to the board during boot-up.
ATTENTION On NUMA-Q systems during system bootup and download of the ptx/SYNC protocol module, the SCC-P LEDs will change states. (Consult your Sequent Service Representative if you have questions.) After the ptx/SYNC protocol module has been successfully downloaded and initiated either by the applicable /etc/rc2.d/S43syncX script (where X is the board number) or the syctl(1M) command, the left LED should be on; the right, off.
In the unlikely event the protocol module panics, both the LEDs will be on. Contact your Sequent Service Representative.
After you have installed ptx/SYNC and the Synchronous Communications Controller(s), or SCC, and have rebooted the new kernel, set up the system to recognize the proper device name for each SCC and to automatically download a particular firmware module during the boot sequence.
For ptx/SYNC and SCC-P board(s) on NUMA-Q systems:
Invoke the ptx/ADMIN menu system by logging in as the root user and enter the following command:
# menu
Select the Network Administration menu.
Select the SYNC Setup menu.
Select the Add a Board option. SYNC boards that have not yet been set up are displayed with temporarily assigned names; for example:
ptx/SYNC Add a Board menu
Board Quad
sync0 0
sync1 0
Press S to select an entry
To select the board you plan to set up, highlight the entry with the cursor control keys and press the S key. The Add a SYNC Board screen will be displayed. In this example::
addnsync
Add a SYNC Board
Enter the Board number for "sync0" ____
Quad Number x
Enter Software(hdlc, sdlc or both) both
Enter a unique board number from 0 to 15 (inclusive). The Quad number is determined by the system and cannot be altered.
Enter a protocol from the list provided:
For example, to set up a new SYNC board in Quad0 for both ptx/SNA and ptx/X.25, enter the following information. You will change the temporary board number for sync0 to sync3.
addnsync
Add a SYNC Board
Enter the Board number for " sync0 " 3
Quad Number 0
Enter Software(hdlc, sdlc or both) both
To verify that the SYNC board has been added, press the Run key (usually F1) to see confirmation. For example:devctl: Assigned sync0 => sync3Board sync3 has been added.Press Return to continue
The board sync3 (device node /dev/com/sync3) is now set up and will automatically be downloaded at system boot time. Press the Return key to redisplay the SYNC Setup Menu.
To verify that the SYNC board has been set up, select the Configure a Board option from the SYNC Setup Menu to see a list of all the properly set-up SYNC boards. For example:
Configure ptx/SYNC Board Configuration
Board Quad Slot Software
0 2 2 hdlc
3 0 2 both(hdlc/sdlc)
To change an entry, highlight the entry and press C.
To update the information, press the Run key (usually F1).
Exit from the menu system (usually F4 or Ctrl-X).
For the initial download of the firmware to the SCC, either reboot the system or execute the following command as the root user:
# /etc/rc2.d/S43syncx start
where x is the number assigned to the board. Each time the system reboots, the board will be downloaded.
ATTENTION This command is downloaded in the background and takes about ten seconds.
Invoke the ptx/ADMIN menu system by logging in as the root user and entering the following command:
# menu
Select the Network Administration menu.
Select the SYNC Setup menu.
Select the Add a DCP Board option.
adddcp
Add a DCP Board
Enter Board Number ___
Enter Protocol Module Name ___
Press Select (F8 or Ctrl-T) to display the DCP boards that have already been set up for the system, along with a description of which communication protocol is allowed to run on each board.
For example, suppose you were to set up a DCP board to allow its use by ptx/X.25:
adddcp
Add a DCP Board
Enter Board Number 3
Enter Protocol Module Name hdlc
Press the Run key (usually F1) to see: Working. . .Press RETURN to redisplay menu.
The DCP board dcp3 (device node /dev/com/dcp3) is now set up and will automatically be downloaded at system boot time. Press the Return key to redisplay the SYNC Setup Menu.
To verify the DCP board setup, select the Display a DCP Board Setup option.
To verify that the DCP board has been set up, select the Display a DCP Board Setup option from the SYNC Setup Menu to see a list of all the properly set up DCP boards. For example:
Display ptx/SYNC Board Configuration
Board Module Software
0 brxsdlc SDLC for ptx/SNA
1 hdlc Downloadable Software for X.25
Exit from the menu system (usually F4 or Ctrl-X).
For the initial download of the firmware to the SCC, either reboot the system or execute the following command as the root user:
# /etc/rc2.d/S43dcpx start
where x is the number assigned to the board. Each time the system reboots, the board will be downloaded.
ATTENTION This command is downloaded in the background and takes about ten seconds.
