Accessing the RPM
Before proceeding with maintenance procedures, refer to "Preparing to Install the Cisco MGX 8850 RPM," in the "Safety Recommendations" section and to "Installing the Cisco MGX 8850 RPM," in the "Removing and Installing the RPM" section.
Remove the RPM from the MGX 8850 chassis, referring to Figure A-1, which shows the layout of the RPM.
Figure A-1 System Card Layout—RPM
Note
To locate components in the following procedures, refer to Figure A-1.
Installing DRAM SIMMs
The RPM has no fixed DRAM; all the main memory is supplied via a DRAM SIMM, which contains both primary and shared memory. Primary memory stores the running configuration and routing tables. Shared memory is used for packet buffering by the RPM network interfaces (see Figure A-1 for the location of main memory in the RPM).
It might be necessary to expand main memory by installing a DRAM SIMM if you are using very large routing tables or many protocols, or if the RPM is set up as a connection device between large external networks and your internal network.
After booting your system, the system banner on the console screen displays only the total amount of main memory, in kilobytes (KB). The following example shows a system with 16,384 KB of main memory:

Tools and Equipment Required
The following tools and equipment are required:
•
ESD-preventive wrist strap
•
The appropriate DRAM SIMM for your RPM model
DRAM SIMM Installation
Take the following steps to install DRAM SIMMs:
Step 1
Turn off the MGX 8850 system but, to channel ESD voltages to ground, do not unplug the power cord.
Step 2
Attach an ESD-preventive wrist strap.
Step 3
Pull the RPM out of the MGX 8850 chassis (refer to "Installing the Cisco MGX 8850 RPM," in the "Removing and Installing the RPM" section.)
Step 4
Turn the RPM so the system card is opposite the position shown in Figure A-1, with the primary memory DRAM SIMM socket toward you.
Step 5
Remove the existing DRAM SIMM by pulling outward on the connectors to unlatch them (see Figure A-2). Be careful not to break the holders on the connector.
Caution
To prevent damage, do not push on the center of the SIMM. Handle the SIMM carefully.
Figure A-2 Removing and Replacing the DRAM SIMM
Step 6
Using the system card orientation shown in Figure A-2, position the new SIMM so that the polarization notch is located at the right end of the SIMM socket. Note that the orientation of the system card is the opposite of that shown in Figure A-1.
Step 7
Insert the new DRAM SIMM by sliding the end with the metal fingers into the SIMM connector socket at approximately a 45-degree angle to the system card. Gently rock the SIMM back into place until the latch on either side snaps into place. Do not use excessive force or the connector could break.
Step 8
Reinstall the RPM in the MGX 8850 chassis (refer to "Installing the Cisco MGX 8850 RPM," in the "Removing and Installing the RPM" section).
Step 9
Connect the RPM to a console terminal.
Step 10
Turn ON the chassis.
If error messages relating to memory are displayed, repeat Step 1 through Step 9, taking care to firmly seat the SIMM in its socket.
Replacing System-Code SIMMs
The system code (software) is stored on Flash or PROM SIMMs. It might be necessary to upgrade the system-code SIMM if you're upgrading to a system code that is too large for the existing system-code SIMM.
The system contains two system-code SIMM slots labeled Bank 1 and Bank 2 (see Figure A-1). You can upgrade the system-code SIMM by replacing the existing SIMM in the Bank 1 slot or installing an additional SIMM in the Bank 2 slot. Table A-5 lists the SIMM slots, Bank 1 and Bank 2, and the proper placement of SIMMs for the desired total SIMM memory.

Flash and PROM SIMMs for the RPM are available only from Cisco Systems. Contact customer service for more information.
Replacing the System-Code SIMMs
Take the following steps to upgrade the system-code Flash SIMMs:
Step 1
Turn OFF the MGX 8850 system but, to channel ESD voltages to ground, do not unplug the power cord.
Step 2
Attach an ESD-preventive wrist strap.
Step 3
Pull the RPM out of the MGX 8850 chassis (refer to (refer to "Installing the Cisco MGX 8850 RPM," in the "Removing and Installing the RPM" section).
Step 4
Turn the RPM so that the system card is opposite the position shown in , with the system-code SIMMs toward you.
Step 5
Locate the system-code SIMMs on the system card. The SIMM sockets are labeled Bank 1 and Bank 2 (see ).
Step 6
Remove the existing system-code SIMM by pulling outward on the connectors to unlatch them. The connector holds the SIMM tightly, so be careful not to break the holders on the SIMM connector (see ).
Caution
To prevent damage, do not push on the center of the SIMMs. Handle each SIMM carefully.
Step 7
Repeat this procedure for all the system-code SIMMs to be replaced.
Figure A-3 Removing and Replacing the System-Code SIMM—Flash SIMM Shown
Step 8
Using the system card orientation shown in , position the new SIMM so that the polarization notch is located at the right end of the SIMM socket. Note that the orientation of the system card is the opposite of that shown in .
Caution
To prevent damage, note that some Flash SIMMs have the components mounted on the rear side; therefore, when inserting the SIMM, always use the polarization notch as a reference and
not the position of the components on the SIMM.
Step 9
Insert the new SIMM by sliding the end with the metal fingers into the appropriate SIMM connector socket (Bank 1 or Bank 2) at approximately a 45-degree angle to the system card. Gently rock the SIMM back into place until the latch on either side snaps into place. Do not use excessive force because the connector could break.
Step 10
Reinstall the RPM in the MGX 8850 chassis (refer to (refer to "Installing the Cisco MGX 8850 RPM," in the "Removing and Installing the RPM" section).
Step 11
Connect the RPM to a console terminal.
Step 12
Turn ON the chassis.
If error messages relating to memory display, repeat Step 1 through Step 11, taking care to firmly seat the SIMM in the socket.
Reading Front Panel LEDs
The LEDs on the front panel of the RPM indicate the current operating condition of the RPM. You can observe the LEDs, note the fault condition the RPM is encountering and then contact your system administrator or customer service, if necessary.
Figure A-4 shows the front panel and LEDs of the RPM. Table A-6 shows how to interpret front-panel LED activity.
Figure A-4 MGX 8850 Expansion Router Module Front Panel LEDs
The LEDs are labeled and indicate overall status and activity on ports by flickering. When there is heavy activity on a port, the LED might be on constantly. If an LED is not on when the port is active and the cable is connected correctly, there might be a problem with the port.

Replacing or Recovering a Lost Password
This section describes how to recover a lost enable or console login password, and how to replace a lost enable secret password on your RPM.
Note
It is possible to recover the enable or console login password. The enable secret password is encrypted, however, and must be replaced with a new enable secret password.
Overview of the Password Recovery Procedure
Following is an overview of the steps in the password recovery procedure:
If you can log in to the router, enter the show version command to determine the existing configuration register value.
Press the Break key to get to the bootstrap program prompt (ROM monitor). You might need to reload the system image by power cycling the router.
Change the configuration register so the following functions are enabled: Break; ignore startup configuration; boot from Flash memory.
Note
The key to recovering a lost password is to set the configuration register bit 6 (0x0040) so that the startup configuration (usually in NVRAM) is ignored. This will allow you to log in without using a password and to display the startup configuration passwords.
Power cycle the router by turning power off and then back on.
Log in to the router and enter the privileged EXEC mode.
Enter the show startup-config command to display the passwords.
Recover or replace the displayed passwords.
Change the configuration register back to its original setting.
Note
To recover a lost password if Break is disabled on the router, you must have physical access to the router.
Details of the Password Recovery Procedure
Complete the following steps to recover or replace a lost enable, enable secret, or console login password:
Step 1
Attach an ASCII terminal to the console port on your RPM.
Step 2
Configure the terminal to operate at 9600 baud, 8 data bits, no parity, and 2 stop bits.
Step 3
If you can log in to the router as a nonprivileged user, enter the show version command to display the existing configuration register value. Note the value for use later. If you cannot log in to the router at all, go to the next step.
Step 4
Press the Break key or send a Break from the console terminal. If Break is enabled, the router enters the ROM monitor, indicated by the ROM monitor prompt (rommon1>). Proceed to Step 6. If Break is disabled, power cycle the router (turn the router off or unplug the power cord, and then restore power). Then proceed to Step 5.
Step 5
Within 60 seconds of restoring the power to the router, press the Break key or send a Break. This action causes the router to enter the ROM monitor and display the ROM monitor prompt (rommon1>).
Step 6
To set the configuration register on a RPM, use the configuration register utility by entering the confreg command at the ROM monitor prompt as follows:
Answer yes to the enable "ignore system config info"? question and note the current configuration register settings.
Step 7
Initialize the router by entering the reset command as follows: rommon2> reset
The router will initialize, the configuration register will be set to 0x142, and the router will boot the system image from Flash memory and enter the system configuration dialog (setup) as follows:
--- System Configuration Dialog --
Step 8
Enter no in response to the system configuration dialog prompts until the following message is displayed:
Press RETURN to get started!
Step 9
Press Return. The user EXEC prompt is displayed as follows:
Step 10
Enter the enable command to enter the privileged EXEC mode. Then enter the show startup-config command to display the passwords in the configuration file as follows:
Router# show startup-config
Step 11
Scan the configuration file display looking for the passwords (the enable passwords are usually near the beginning of the file, and the console login or user EXEC password is near the end). The passwords displayed will look something like this:
enable secret 5 $1$ORPP$s9syZt4uKn3SnpuLDrhuei
enable password 23skiddoo
The enable secret password is encrypted and cannot be recovered; it must be replaced. The enable and console passwords may be encrypted or clear text. Proceed to the next step to replace an enable secret, console login, or enable password. If there is no enable secret password, note the enable and console login passwords if they are not encrypted and proceed to Step 16.
Caution
Do not execute the next step unless you have determined you must change or replace the enable, enable secret, or console login passwords. Failure to follow the steps as shown may cause you to erase your router configuration.
Step 12
Enter the configure memory command to load the startup configuration file into running memory. This action allows you to modify or replace passwords in the configuration.
Step 13
Enter the privileged EXEC command configure terminal to enter configuration mode:
Hostname# configure terminal
Step 14
To change all three passwords, enter the following commands:
Hostname(config)# enable secret newpassword1
Hostname(config)# enable password newpassword2
Hostname(config)# line con 0
Hostname(config-line)# password newpassword3
Change only the passwords necessary for your configuration. You can remove individual passwords by using the no form of the above commands. For example, entering the no enable secret command will remove the enable secret password.
Step 15
You must configure all interfaces to be not administratively shutdown as follows:
Hostname(config)# interface fastethernet 0/0
Hostname(config-int)# no shutdown
Enter the equivalent commands for all interfaces that were originally configured. If you omit this step, all interfaces will be administratively shutdown and unavailable when the router is restarted.
Step 16
Use the config-register command to set the configuration register to the original value noted in Step 3 or Step 7, or to the factory default value 0x2102 as follows:
Hostname(config)# config-register 0x2102
Step 17
Press Ctrl-Z (hold down the Control key while you press Z) or enter end to exit configuration mode and return to the EXEC command interpreter.
Caution
Do not execute the next step unless you have changed or replaced a password. If you skipped Step 12 through Step 15, skip to Step 19. Failure to observe this caution will cause you to erase your router configuration file.
Step 18
Enter the copy running-config startup-config command to save the new configuration to nonvolatile memory.
Step 19
Enter the reload command to reboot the router.
Step 20
Log in to the router with the new or recovered passwords.
This completes the steps for recovering or replacing a lost enable, enable secret, or console login password.
Virtual Configuration Register Settings
The RPM has a 16-bit virtual configuration register, which is written into NVRAM. You might want to change the virtual configuration register settings for the following reasons:
•
Set and display the configuration register value.
•
Force the system into the ROM monitor or boot ROM.
•
Select a boot source and default boot filename.
•
Enable or disable the Break function.
•
Control broadcast addresses.
•
Set the console terminal baud rate.
•
Recover a lost password (ignore the configuration file in NVRAM).
•
Enable Trivial File Transfer Protocol (TFTP) server boot.
Table A-7 lists the meaning of each of the virtual configuration memory bits and defines the boot field names.
Caution
To avoid confusion and possibly halting the RPM, remember that valid configuration register settings might be combinations of settings and not just the individual settings listed in
Table A-7. For example, the factory default value of 0x2102 is a combination of settings.

Changing Configuration Register Settings
Take the following steps to change the configuration register while running Cisco IOS software:
Step 1
Enter the enable command and your password to enter privileged mode:
Step 2
Enter the configure terminal command at the privileged-level system prompt (#):
MGX 8850-RPM# configure terminal
Step 3
To set the contents of the configuration register, enter the configuration command config-register value, where value is a hexadecimal number preceded by 0x (refer to Table A-7 and Table A-8):
MGX 8850-RPM(config)# config-register 0xvalue
(The virtual configuration register is stored in NVRAM.)
Table A-8 Explanation of Boot Field (Configuration Register Bits 00 to 03)
|
|
0x0 |

0x3-0xF |
Specifies a default filename for booting over the network from a TFTP server. Enables boot system commands that override the default filename for booting over the network from a TFTP server. |
Step 4
Press Ctrl-Z to exit configuration mode.
The new settings will be saved to memory; however, the new settings are not effective until the system software is reloaded by rebooting the RPM.
Step 5
To display the configuration register value currently in effect and the value that will be used at the next reload, enter the show version EXEC command. The value displays on the last line of the screen display:
Configuration register is 0x142 (will be 0x102 at next reload)
Step 6
Reboot the RPM.
The new value takes effect. Configuration register changes take effect only when the RPM restarts, which occurs when you turn the system on, or when you enter the reload command.
Virtual Configuration Register Bit Meanings
The lowest four bits of the virtual configuration register (bits 3, 2, 1, and 0) form the boot field (see Table A-8). The boot field specifies a number in binary form. If you set the boot field value to 0, you must boot the operating system manually by entering the b command at the bootstrap prompt, as follows:
> b [ tftp ] flash filename
The b command options are as follows:
•
b—Boots the default system software from ROM
•
b flash—Boots the first file in Flash memory
•
b filename [host]—Boots from the network using a TFTP server
•
b flash [filename]—Boots the file filename from Flash memory
For more information about the command b [tftp] flash filename, refer to the Cisco IOS configuration publications.
If you set the boot field value to a value of 0x2 through 0xF, and a valid system boot command is stored in the configuration file, the RPM boots the system software as directed by that value. If you set the boot field to any other bit pattern, the RPM uses the resulting number to form a default boot filename for booting from the network using a TFTP server (see Table A-9).

In the following example, the virtual configuration register is set to boot the RPM from Flash memory and to ignore Break at the next reboot of the RPM:
Enter configuration commands, one per line.
Edit with DELETE, CTRL/W, and CTRL/U; end with CTRL/Z
boot system flash [filename]
The RPM creates a default boot filename as part of the automatic configuration processes. The boot filename consists of cisco plus the octal equivalent of the boot field number, a hyphen, and the processor type.
Note
A boot system configuration command in the RPM configuration in NVRAM overrides the default boot filename.
Bit 8 controls the console Break key. Setting bit 8 (the factory default) causes the processor to ignore the console Break key. Clearing bit 8 causes the processor to interpret the Break key as a command to force the system into the bootstrap monitor, thereby halting normal operation. A break can be sent in the first 60 seconds while the system reboots, regardless of the configuration settings.
Bit 10 controls the host portion of the IP broadcast address. Setting bit 10 causes the processor to use all zeros; clearing bit 10 (the factory default) causes the processor to use all ones. Bit 10 interacts with bit 14, which controls the network and subnet portions of the broadcast address (see Table A-10).

Bit 13 determines the server response to a bootload failure. Setting bit 13 causes the server to load operating software from ROM after five unsuccessful attempts to load a boot file from the network. Clearing bit 13 causes the server to continue attempting to load a boot file from the network indefinitely. By factory default, bit 13 is set to 1.
Enabling Booting from Flash Memory
To disable Break and enable the boot system flash command, enter the config-register command with the value shown in the following example:
MGX 8850-RPM# config tRPM
Enter configuration commands, one per line.
Edit with DELETE, CTRL/W, and CTRL/U; end with CTRL/Z
Copying a Cisco IOS Image to Flash Memory
You may need to copy a new Cisco IOS image to Flash memory whenever a new image or maintenance release becomes available. Use the copy tftp flash command for the copy procedure.
Take the following steps to copy a new image to Flash memory from a TFTP server:
Step 1
Enter the show flash command to ensure that there is enough space available before copying a file to Flash memory. Compare the size of the file you want to copy to the amount of available Flash memory displayed.
Step 2
Make a backup copy of the current image. Enter enable mode and then enter the copy flash tftp command. Ensure that the filename of the current image is different from the new image so that you do not overwrite it.
Step 3
Enter the copy tftp flash command to copy the new image into Flash memory:
MGX 8850-RPM# copy tftp flash
The following messages display:
This process will accept the copy options and then terminate
the current system image to use the ROM based image for the copy.
Routing functionality will not be available during that time.
If you are logged in via telnet, this connection will terminate.
Users with console access can see the results of the copy operation.
Step 4
Press Return to confirm.
If there is an image already in Flash memory, the RPM displays the name and size of the file. Then the RPM prompts you for the IP address or name of the remote host:
Address or name of remote host [hostname]?
The remote host can be a server or another router with a valid Flash system software image.
Step 5
Enter the IP address or name of the remote host.
The RPM then prompts you for the name of the source file:
Step 6
Enter the name of the source file. The following prompt displays:
Destination file name [filename]?
Step 7
Press Return to accept the default filename or enter a different filename. Messages similar to the following display:
Accessing file 'master/igs-j-l.110-4.2' on hostname...
Loading master/igs-j-l.110-4.2 from 172.16.72.1 (via Ethernet0): ! [OK]
