MSFC Is in the ROMmon State

The output in this section is from the show module command when MSFC is in the ROMmon state.

Note: Issue one of these session commands:


 

If the MSFC that you want to recover physically resides in the Supervisor Engine module in slot 1, issue the session 15 command.


 

If the MSFC is in slot 2, issue the session 16 command.


 

Note: If the MSFC of the standby Supervisor Engine is inaccessible, see the instructions in the Recover a Standby Supervisor Engine MSFC in Dual Supervisor Engines in a Chassis section of this document before you proceed.


 

Cat6500 (enable) session 15

Trying Router-15...

Cat6500> (enable) show module 15
Module 15 is not installed.


 

This procedure guides you through the recovery of the MSFC when it is in the ROMmon state:


 

Connect to the Supervisor Engine through a console port connection.

Note: Do not connect through Telnet.


 

At the prompt, issue the switch console command.


 

Cat6500 (enable) switch console

Trying Router-15...
Connected to Router-15.
Type ^C^C^C to switch back...

!--- Press Enter here.

rommon 1 >


 

If you are able to access the ROMmon of the MSFC, proceed to Step 13.


 

If you are unable to access the ROMmon, as indicated in Step 2, complete these steps:


 

Reset the Supervisor Engine switch.


 

After you reset the switch, issue the switch console command as soon as you are able to access the Supervisor Engine command prompt.

At this point, you should be able to see the MSFC boot.


 

Immediately press Ctrl-Break in order to break into the MSFC ROMmon.

If you are able to access the MSFC rommon > prompt, proceed to Step 13.

Note: The break sequence that you enter depends on the terminal emulation software and the operating system that you use. For example, HyperTerminal on Microsoft Windows 2000 uses Ctrl-Break as the break sequence. For more information, refer to Standard Break Key Sequence Combinations During Password Recovery.


 

If attempts to access the MSFC ROMmon fail, power down the switch and physically remove the MSFC bootflash.

These illustrations show the physical bootflash locations with red arrows:

Power the switch back up and issue the switch console command in order to access the MSFC ROMmon.

Note: If output still scrolls on the screen or you are not presented with the rommon > prompt, send a break sequence to the MSFC. Refer to Standard Break Key Sequence Combinations During Password Recovery for more information.


 

At the prompt, issue the set command in order to display the current ROMmon boot variable settings.


 

rommon 2 > set

PS1=rommon ! >
BOOTLDR=bootflash:c6msfc-boot-mz.121-6.E
BOOT=bootflash:c6msfc-jsv-mz.121-6.E,1;?=1


 

Issue the BOOT= command and the BOOTLDR= command in order to reset the BOOT and BOOTLDR variables.

Note: These commands are case sensitive.


 

rommon 2 > BOOT=

rommon 3 > BOOTLDR=


 

Issue the confreg 0x0 command in order to set the configuration register to 0x0.

Note: This command is case sensitive.


 

rommon 4 > confreg 0x0


 

At the prompt, issue the sync command in order to synchronize the boot and configuration register settings, and then issue the reset command.


 

rommon 5 > sync

rommon 6 > reset

After the MSFC resets, issue the set command in order to verify that the settings were saved.


 

rommon 1 > set

PS1=rommon ! >
BOOT=
BOOTLDR=
CONFREG=0x0


 

Power down the switch and reinsert the MSFC bootflash.


 

Power up the switch and issue the switch console command in order to access the MSFC.


 

Issue the dir bootflash: command in order to display the contents of the MSFC bootflash:


 

rommon 1 > dir bootflash:

File size Checksum File name
1730952 bytes (0x1a6988) 0x880dbda7 c6msfc-boot-mz.121-6.E1.bin
12212028 bytes (0xba573c) 0xbe32bc20 c6msfc-jsv-mz.121-8a.E2


 

Issue the boot bootflash: command in order to boot the MSFC.

Be sure to specify the appropriate system image (jsv, dsv, isv) that the dir bootflash: command output displays.

Note: Do not specify the image with “boot” in the file name.


 

rommon 1 > boot bootflash:c6msfc-jsv-mz.121-8a.E2
