Warning: Throughout this procedure, make sure to attach the ESD wrist strap to the RNC ground connection and put the strap on. When removing a CMM card, use the screwdriver to remove the board retention screws that fasten the board to the chassis. There is a screw located below the ejector handle, and a second screw located at the opposite end of the faceplate from the ejector handle.
Warning: There are two CMM cards for each Shelf. Never pull out two cards out simultaneously. Otherwise, it can result in an outage.

CMM configure procedure

A. CMM Password – Perform the following steps to examine and set the root user password on the replacement CMM.

Open a connection to the replacement CMM card via the terminal server. Standard CMM Terminal server port connections are in the Table 1.

a. Log into the replacement CMM. (login: root password: newsys)

b. If the login attempt is successful, the root user password is set correctly. You have completed this procedure.

c. If login attempts fails, go to the next step.

d. Log into the replacement CMM. (login:root password:cmmrootpass)

e. Enter the passwd command to reset the root user password to newsys.

When prompted for the new password and when asked to reconfirm the new password, enter newsys.

B. CMM IP settings – Perform the following steps to configure the CMM IP settings.

Open a connection to the replacement CMM card via the terminal server.

a. Edit the IP configuration for the interface 0.

b. vi /etc/ifcfg-eth0

c. Modify the lines shown below, if necessary, and save the file. The IP addresses can be determined from Table 2.

STATICIP=”<CMM IP 0>

”NETMASK0=”255.255.0.0”

Where:

<CMM IP 0> is the IP address from Table 2.

Edit the IP configuration for the interface 1.

d. vi /etc/ifcfg-eth1

e. Modify the lines shown and save the file. The IP addresses can be determined from Table 2.

STATICIP1=”<CMM IP 1>”

STATICIP2=”<CMM IP 2>”

NETMASK1=”255.255.240.0”

NETMASK2=”255.255.240.0”

Where:

<CMM IP 1> and <CMM IP 2> are the IP address from Table 2.

Enter the following commands to check that the changes have taken place.

/etc/rc.d/network reload

ifconfig

NOTE: Some times an error is seen when the ifconfig command is first entered. If the error is seen, just repeat the command.

C. CMM prompt: Perform the following steps to set the prompt on the CMM card.

Open a connection to newly replaced CMM via the terminal server. Refer to Table 1 for the CMM terminal server port.

NOTE: Procedures to open a connection via the terminal server are provided in Section 191.

Log into the CMM. (login:root password:newsys)

Edit the profile on the first CMM card.

vi /etc/profile

Add the following under the “# User specific …” line in the file, and then save the file.

PS1=”<Prompt># “

Where:

<Prompt> is the prompt name from Table 3 below.

NOTE: The value entered for <Prompt> must have a space after the hash (#) at the end before the ending quote.

Prompt Name

CMM Upper Shelf – 1

cmm1-1

CMM Upper Shelf – 2

cmm1-2

CMM Lower Shelf – 1

cmm2-1

CMM Lower Shelf -2

cmm2-2

D. CMM Reboot Perform the following steps to reboot the CMM card.

1. Open a connection to newly replaced CMM via the terminal server. Refer to Table 1 for the CMM terminal server port.

2. Type reboot to reboot the card. Wait for the card to complete it’s reboot before continuing.

3. Close the serial connection.

E. CMM CARD FIRMWARE UPDATES

Check RNC Status

Before upgrading the firmware and software of the newly replaced CMM, the RNC must be in the online state. Perform the following steps to verify the RNC is in the online state.

1. Log into the RNC as root.

2. Enter the following command

rnccstat

Determine Active FMS

To perform a firmware update via the Ethernet connection, the active server must be determined. Perform the following steps to determine the active OAM blade.

1. Log in to the RNC as root.

2. Type the command

ifconfig –a

In the output, look for the IP address 10.6.0.54.

NOTE: The fms must be ONLINE to see this address. Ensure the fms is online by using the rnccstat command.

3. If the IP address is seen, then the connection is to the active OAM blade. If it is not seen, then the other OAM blade is the active blade.

Update CMM Firmware

Perform the following steps to update the CMM firmware of the replacement CMM card.

1. From the active FMS, change directories to the CMM FW location

cd /flx/FBPfwcmm/current/fwupd

2. Update the FW on the CMM.

./fwupd_cmm –UH –t <cmm> –u root –p newsys

Where:

<cmm> is the CMM hostname of the replaced card from Table 4.

The update will be performed and the card will reboot and go active when it has completed.

3. Check the firmware on the just updated CMM card.

./fwupd_cmm –C –t <cmm> –u root –p newsys

If the command returns equal then the update was successful. Otherwise, the update was not successful, repeat step 2 to attempt the update a second time.

F. CMM CARD SOFTWARE UPDATES

Update CMM Software

In addition to the firmware, there is also a software update. Perform the following steps to update the software of the replacement CMM card.

1. From the active FMS, change directories to the CMM FW location

cd /flx/FBPswcmm/current/swupd

2. Perform the following command to update the CMM software.

./swupd_cmm –UH –t <cmm> –u root –p newsys

Where:

<cmm> is the hostname of the replacement CMM from Table 4.

3. Check the software version for the CMM card just updated.

./swupd_cmm –C –t <cmm> –u root –p newsys

If the result is equal, then the software update completed successfully. If it is not equal, attempt to perform step 2 a second time.

Verify CMM Card Status

Perform the following steps to verify the replacement CMM card.

Step

Action

1

Log into the OMC GUI.

2

From the OMC Desktop window, click on Network Network Manager, or click on the icon.

The Network Manager window will appear.

3

In the Network Manager screen, expand the tree until the RNC objects are seen.

4

Click the arrow on the left of the RNC to open the RNC tree.

5

Expand the Cabinet under the LRNC until the CMM card is seen. Verify the replacement CMM now has enabled indication and is free of alarms.
