Sup6E stuck in ROMMON mode

Community,

 

I have a SUP 6-E in a 4510R chassis. I noticed that the active sup came up fine but the standby was showing Disabled in the show redundancy states output. I plugged in my console cable and lo and behold the standby sup was in ROMMON. I tried the "boot" command but it failed because there is no IOS image in the bootflash: of this supervisor. I need direction on how to load the IOS into bootflash from ROMMON. Ive scoured the internet but am unable to find an answer. Things ive tried:

1) Changing the Config register so itll load into <boot> mode. When I type confreg 0x02101 nothing happens. It stays at 0x2102. I tryed typing confreg=0x0101 but for some reason it stays permanently but does nothing.

 

rommon 7 >confreg 0x2101
usage: confreg

rommon 8 >set
PS1=rommon ! >
RommonVer=12.2(44r)SG10
ConfigReg=0x0102
confreg=0x0101

 

2) tried using xmodem command but the command isnt even available.

 

rommon 9 >xmodem

monitor: command "xmodem" not found

 

Ive pasted some output below:

rommon 11 >dir bootflash:

File Size (Bytes) File Name

Total space = 122007552 bytes, Available = 116727808 bytes

 

rommon 12 >boot
boot: can not determine first file name on device "bootflash:"

 

How can I load the IOS into bootflash: from ROMMON? Thanks.

Reza,

 

Thank you for this! I will attempt these steps and let you know how it goes. On the surface it appears this may work! Thanks.

Doesn't a Sup6 have an external flash port?

Leo,

 

They do! I think I see where youre going with this. If I cannot get it to go using the link Reza posted above, ill try to move the IOS to a 512MB CF card I have here and see if I can upload that way! Thanks!
