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.
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.
Table 2-3 shows the NCB module connectors on the front panel.

Table 2-5 lists physical dimensions.
The NCB module is positioned in Slot 17 in the Cisco ONS 15252 Multichannel Unit (MCU) as shown in Figure 2-2.
Figure 2-2 Mounting an NCB module
Step 1 Back up all NCB files to a laptop or PC as described in the Cisco 15200 Command Line Interface Manual and in the "Back up Files from the Network Control Board" procedure.
Step 2 Disconnect the front panel Ethernet cable from the NCB module.
Step 3 Loosen the thumbscrews.
Step 4 Carefully remove the NCB module from the ONS 15252 MCU.
Step 5 If you will not immediately replace the NCB, install a 20 mm (0.8")-wide dummy front where the NCB was removed from the ONS 15252 MCU.
Step 1 Open a Command (MS-DOS) Prompt window on your workstation. To do so, select Start > Programs and select Command Prompt (it may be under Accessories).
Step 2 Telnet to the NCB. To do so, at the C:\> prompt, type telnet <ipaddress> where <ipaddress> is the IP address of the NCB. Press Enter. You should get a login prompt from the NCB
Step 3 Log into the 15200 as an administrator user:
Step 4 Determine the current software and hardware version.
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.
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.
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.
Step 3 Open an FTP session to the NCB.
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.
Step 6 Back up the rest of the files that reside in the NCB to your PC.
Step 7 In your PC or laptop open Windows Explorer and verify that all of the files originally listed in the NCB are now in the backup directory.
Step 8 Once you verify that you have copied all the NCB files to the PC backup directory, close the ftp window. To do so, at the ftp> prompt, type bye and press Enter. This will take you back to the c:\foldername> prompt.
Before replacing the NCB, back up all files as described in the "Back up Files from the Network Control Board" procedure.
Step 1 Disconnect the Ethernet cable from the NCB module.
Step 2 Loosen the thumbscrews.
Step 3 Carefully remove the NCB module from the ONS 15252 MCU.
Step 4 Align the replacement NCB module with the NCB module slot.
Step 5 Carefully insert the module into the slot.
Step 6 Tighten the thumbscrews.
Step 7 Connect the Ethernet cable to the NCB module.
Step 1 Create an administrator user and assign an IP address, mask, and gateway to the new NCB. Use the CIM RS-232 cable (P/N 72-2746-01) provided with the system.
Step 2 Connect your PC or Laptop serial COM port to the ONS 15252 MCU management access (MA) port on the CIM board.

Step 3 Make sure that the connection to the NCB is has been terminated. Otherwise the Hyper Terminal cannot connect to the system.
Step 4 On the PC or laptop, open the terminal emulation program such as Hyper Terminal and configure the COM port.
Step 1 Select Start > Programs and select Accessories > Communication > Hyper Terminal.
Step 2 Press Cancel.
Step 3 In the File pull-down menu, select Properties (the window is called "New Connection Properties").
Step 4 In Connect using, select the COMx Port. Press Configure.
Step 5 In the "COMx properties" window, select:
Step 6 Press OK.
Step 7 In New Connection Properties, select the Settings menu.
Step 8 Select VT100 as the emulation.
Step 9 Go to ASCII settings. Mark Send line ends with line feeds (all other fields are not marked). The Hyperterminal screen appears.
Step 10 Press Enter. The system responds with a login prompt. Press Enter again. Because no password is needed press Enter a third time. You should now see the NCB:> prompt.
Step 11 Create a user with administrator privileges:
Step 12 Set the IP address of the NCB module.
Step 13 Disconnect the CIM RS-232 adapter cable.

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.
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.
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).
Step 13 Check the new NCB software version.
