2.1.1 Module Function

The NCB module is the central processor unit with all of its peripherals.

The SNM software on the NCB controls the Client Layer Interface Port (CLIP) modules on the internal bus. In addition to controlling all of the ONS 15200 system CLIP modules, the NCB module collects information about system status, alarms, parameters, and actions on the internal data bus. You can also store performance monitoring data on the NCB and upload the data to external media.

With certain limitations described below, you can configure one or two active NCBs as CLIP managers in a network; an NCB in a network that is not provisioned as an active manager of a CLIP can still inventory the CLIP. Both these functions are limited to a distance of two CAN bus extensions and two QPP jumps.

  • The internal CAN bus can be extended with a CAN bus extension cable from one MCU or SCU to another co-located MCU or SCU to connect two or more co-located shelves to a logical network element (NE). (A maximum of four MCUs can be connected to form one logical NE; up to 60 DCN addresses are possible for CLIPs on one extended CAN bus.)
  • A QPP jump is the logical connection of the in-band communication channel between a pair of two CLIPs forming one path.

Read the status of the NCB board and the entire subnetwork on the Communication Interface module (CIM) immediately beneath it.

Access the NCB board from the Ethernet port on the front panel or the MA port on the CIM. On the CIM, use the RS-232 adapter (P/N 72-2746); the EIA/TIA-232 interface requires the parameters in Table 2-1.

Step 3   Log into the 15200 as an administrator user:

a. At the NCB login prompt type a username with administrator privileges and press Enter.

b. At the password prompt type the password for the administrator user and press Enter.

If the login is successful you should see the NCB:> prompt.


Note    More than one user with the same username cannot be logged in at the same time. Each username can log in once per session.

Step 4   Determine the current software and hardware version.

a. At the NCB:> prompt type configure system and press Enter. You should now see the NCB:= prompt

b. At the NCB:= prompt type version and press Enter. Write down the NCB Revision number and the SNM Version Number.

Step 5   List the files that reside in the NCB. To do so, at the NCB:= prompt, type list 0 and press Enter. You will see the names of all the files that currently reside in the NCB. Record the number of files. In the next section of this procedure you will backup these files to your PC.

Step 6   Determine if you need to defrag the NCB, i.e. if any of the files listed have the word "deleted" next to them. If none of the files listed have the word [deleted] next to the file name, skip this step.

a. To remove files marked as deleted, at the NCB:= prompt, type defrag 0 and press Enter. You will see the message "Defragmentation in progress..." This command will take up to 2 minutes to complete.


Note    You must wait for this command to complete.

b. When the process is complete, you will see the NCB:= prompt again. Type list 0 and press Enter. Verify that no file shows the word [deleted] next to it.

Step 7   Verify the IP configuration. To do so, at the NCB:= prompt type ipconf and press Enter. You will see the current NCB IP address, the subnet mask, and the gateway. Record this information for later use.

Step 8   Logout of the NCB. To do so, at the NCB:= prompt, type exit and press Enter.
At the NCB:> prompt, type exit and press Enter.





Back up Files from the Network Control Board

Complete the following steps to backup all of the NCB files to your PC.


Step 1   Open a Command Prompt window. To do so, select Start > Programs and select Command Prompt (it may be under Accessories).

Step 2   Create a directory to save the backup files.

a. At the C:\> prompt, type mkdir <foldername> and press Enter where foldername is the name of the directory you want to create.

b. Go to the directory that will hold the backup files. At the C:> prompt, type cd <foldername>, where foldername is the destination folder. Press Enter.

Step 3   Open an FTP session to the NCB.

a. At the c:\foldername> prompt, type ftp <ipaddress>, where ipaddress is the IP address of the 15200 system NCB. Press Enter.

b. At the User prompt, type an ONS 15200 username with administrator privileges, followed by the password. If the username and password are correct you should see a message showing that the username is logged in.

Step 4   At the ftp> prompt, type dir and press Enter. You will see a list of all the files in the NCB.

Step 5   Copy all the files in the NCB to the backup directory in your PC. Start with the file that contains the snm.out NCB software.

a. At the ftp> prompt, type bin and press Enter.

b. At the ftp> prompt, type get snm.out and press Enter.

Step 6   Back up the rest of the files that reside in the NCB to your PC.

Restore the Configuration Files to the New NCB

This procedure explains how to copy all the files, except the snm.out and qdbs.cfg files, from the PC backup directory to the new NCB.


Note   We do not copy the snm.out and qdbs.cfg files to the new NCB because the new NCB should already have these files. These two files are installed at the factory.


Step 1   Verify that your PC or laptop is connected to the Ethernet port on the NCB module.

Step 2   Open a Command prompt window. To do so, select Start >Programs and select Command Prompt (it may be under Accessories).

Step 3   Go to the directory where you backed up the original NCB files. To do so, at the C:> prompt type cd <foldername>, where foldername is the folder where the backed up files reside. Press Enter.

Step 4   Start an ftp session to the NCB. To do so, at the C:\foldername> prompt type ftp <ipaddress>, where ipaddress is the IP address of the new NCB. Press Enter.

Step 5   Log into the system.

a. At the NCB ftp> User login prompt, type the username of the administrator that you created in the "Initialize the NCB" procedure and press Enter.

b. At the password prompt, type the password and press Enter. You should receive a message saying that you were successful logging in.

Step 6   Determine which files are already on the NCB. To do so, at the ftp> prompt type dir and press Enter. You will see a list of all files in the NCB. At minimum you should see the snm.out and qdbs.cfg files.

Step 7   Type ascii and press Enter.

Step 8   One at a time, move the files (except for snm.out and qdbs.cfg) from the backup directory to the new NCB. To do so, at the ftp> prompt, type put <filename> and press Enter, where filename is the file that you want to move from the backup directory to the new NCB. You should see a message showing that the file has been successfully transferred.


Note    The snm.out and qdbs.cfg files are the only files not transferred to the new NCB.

Step 9   Repeat Step 8 for each of the files that you wish to transfer to the new NCB. If the snm.out and the qdbs.cfg files are present on the original NCB, do not put these two files on the new NCB.

Step 10   Verify that the new NCB shows the same files that the original NCB. To do so, at the ftp> prompt type dir and press Enter. Verify that you count the same number of files as were in the original NCB.

Step 11   Close the ftp window. At the ftp> prompt, type bye.

Step 12   Reboot the NCB for the downloaded configuration to take effect.

a. Telnet to the NCB using the administrator username and password you created earlier (see the "Initialize the NCB" procedure).

b. At the NCB:> prompt, type configure system and press Enter.

c. At the NCB:= prompt, type reboot and press Enter.


Note    The NCB reboot takes approximately 1 minute.

d. Telnet to the new NCB with an administrator username that existed previously in the original NCB.


Note    The user name you created in the "Initialize the NCB" procedure is no longer valid after the reboot.

Step 13   Check the new NCB software version.

a. At the NCB:> prompt type configure system and press Enter.

b. At the NCB:= prompt type version and press Enter. Verify that the software version is the same as in the original NCB.
