Network Control Board Module

This chapter describes the Cisco ONS 15200 Network Control Board (NCB) module. For information about software configuration, refer to the Cisco ONS 15200 Command Line Interface Manual.

2.1 Functional Description

Figure 2-1 shows the front panel of the NCB module.

2.1.1 Module Function

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

The Subnetwork Manager (SNM) software on the NCB manges 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 from the CLIP 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 of these functions are limited to a distance of two controller area network (CAN) bus extensions and two Qeyton proprietary protocol (QPP) jumps.

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

Access the NCB from the Ethernet port on the front panel or the MA port on the CIM. On the CIM, use the EIA/TIA-232 (RS-232) cable (P/N 72-2746-01 contained in the ATO NEBS3, CIM, Acc KIT [CISCO15252-N3]). This interface requires the parameters in Table 2-1.

2.1.2 Alarm and Supervisory Software

The NCB hosts the SNM software. The SNM supervises the CLIP modules and manages the communication channels to other management systems.

Note   The CLIP modules, when powered on, synchronize with their respective mates. Traffic comes up without the assistance of an NCB.

2.1.3 Front-Panel Indicators, Connections, and Adjustments

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

Indicators for the NCB are visible on the front panel of the CIM.

Table 2-3 shows the NCB module LEDs on the front panel of the CIM.

Note   When the red and yellow LEDs are flashing simultaneously, the NCB is rebooting. If the LEDs flash continuously, the NCB has entered boot mode. Refer to the Cisco ONS 15200 Command Line Interface Manual for further information.

2.2 Technical Specifications

This section covers optical, electrical, environmental, and mechanical specifications for the NCB module. Optical specifications and default thresholds do not apply.

2.2.1 Electrical Specifications

2.2.2 Environmental Specifications

Table 2-4 lists the environmental specifications for the NCB.

2.2.3 Mechanical Specifications

Table 2-5 lists physical dimensions.

2.3 Removing and Replacing an NCB Module

This section explains how to remove and replace NCB modules.

Note   Under normal circumstances, removing the NCB is not traffic affecting.

The NCB module is positioned in slot 17 in the Cisco ONS 15252 MCU as shown in Figure 2-3.

To replace the NCB module, complete the following procedures:

1. Back up Files from the Network Control Board

2. Determine the Parameters of the Existing Network Control Board

3. Remove the Network Control Board

4. Replace the NCB

5. Initialize the NCB through LAN/WAN or Initialize the NCB through the EIA/TIA-232 Port

6. Configure the COM Port on the PC/Laptop

7. Create a User and Set the IP Address

8. Restore the Configuration Files to the New NCB or Restore the Configuration Files to a replacement NCB

2.3.1 Back up Files from the Network Control Board

Complete the following steps to back up all of the NCB files to your PC:

Step 2   Create a directory to save the backup files.

Step 3   Open an FTP session to the NCB.

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 file.

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 another command prompt window and verify that all of the files originally listed in the NCB are now in the backup directory.

Step 8   After 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.

---

Note    Always back up the qdbs.cfg file and the snm.out file together. Do not put files in Table 2-6 on the new NCB if used as replacement.

---

Table 2-6 lists the files that are not restored to the new NCB if used as a replacement.

---

Note    The file sys_inet.sys contains the ipaddress. Copying it onto the board will copy the old ipaddress onto the new NCB. The file network.cfg contains info about the network, including the neid of the snm (NCB board). The new board will have a different neid than the old one; thus, a new network.cfg file needs to be created. The file snm.out is the executable file. The file qdbs.cfg is a configuration file used by snm.out, which is version specific, i.e., tied to a particular version of snm.out.

---

---

Note    Instead of using the old network.cfg file, create a new using the commit network command.

---

Complete the following steps to create a new network.cfg file from the command-line interface (CLI).

Step 2   At the configure network prompt (Network:>) type commit network. Press Enter.

Step 3   This command might take up to15 seconds to execute. This command creates a new network.cfg file, but depending on your configuration a number of intermediary files might also be created.

Step 4   Type exit and press Enter to get back to the login prompt.

Step 5   To remove any extra files, execute configure system from the login prompt (to get into the configure system mode), followed by defrag 0.

2.3.2 Determine the Parameters of the Existing Network Control Board

Follow the steps to determine the parameters of the NCB

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:

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. A user can not launch multiple sessions.

---

Step 4   Determine the current software and hardware version.

Step 5   List the files that reside on 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 on the NCB. Write down the number of files and names.

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.

---

Note    You must wait for this command to complete.

---

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   Log out of the NCB. To do so, at the NCB:= prompt, type exit and press Enter.
At the NCB:> prompt, type exit and press Enter.

2.3.3 Remove the Network Control Board

Step 3   Disconnect the CIMEIA/TIA-232 adapter cable.

The Subnetwork Manager on the NCB module now has an IP address and can be accessed directly at the Ethernet port on the NCB module.

Figure 2-6 displays the NCB start screen in the HyerTerminal window.

2.3.9 Restore the Configuration Files to the New NCB

This procedure explains how to copy all the files from the PC backup directory to the new NCB with the current SNM version.

Step 2   Open an MS-DOS command prompt window. To do so, select Start > Run. Open a command window by typing cmd (or command) in the Run dialog box.

Step 3   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 4   Open an FTP session to the NCB. At the C:\foldername> prompt, type ftp ipaddress, where ipaddress is the IP address of the 15200 system NCB. Press Enter.

Step 5   Log into the system.

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 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.

Step 10   Verify that the new NCB shows the same files as 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.

---

Note    The NCB reboot takes approximately 1 minute.

---

---

Step 3   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 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.

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 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.

Table 2-6 lists the files that are not restored to the replacement NCB.

---

Note    The file sys_inet.sys contains the ipaddress. Copying it onto the board will copy the old ipaddress onto the new NCB. The file network.cfg contains info about the network, and the neid of the snm (NCB board). The new board will have a different neid than the old one; thus, a new network.cfg file will have to be created. The file snm.out is the executable file. The file qdbs.cfg is a configuration file used by snm.out, which is version specific.

---

---

Note    For the network.cfg file create a new one by 'commit network' instead.

---

Complete the following steps to create a new network.cfg file from CLI (Command Line Interface)

Step 10   Verify that the new NCB shows the same files as 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.

---

Note    The NCB reboot takes approximately 1 minute.

---

---

Note    The user name you created in the "Create a User and Set the IP Address" procedure is no longer valid after the reboot, because only users defined in users.cfg will be valid. After reboot the users.cfg that is copied on the NCB contains all the user settings from the previous NCB.

---

Step 13   Check the new NCB software version.
