Converting SSG to JunOS

Hi,  I am trying to convert a SSG 550M to JunOS

 

SSG has a 128MB flash card and ScreenOS 5.4.0r8.0

 

I logged in, and per the migration instructions pdf did:

 

SSG550-> set boot junos
SSG550-> save
Save System Configuration  ...
Done

 

However after swapping the CF card to one with JunOS, the device will not boot.  It does not recognize the boot device.  I swapped the CF cards, booted ScreenOS again and repeated the process, but no luck.

 

I'm swapping with a 1GB 3rd party CF card that is tested to work fine in a J4350. 

 

Does anyone have any ideas for something I might have missed?  Should J4350 CF & software run on SSG550 (hardware platform is same family so I thought yes)

Re: Converting SSG to JunOS

I've never heard of a DIY version of the upgrade. My understanding is you need a new eeprom as well. We sell a kit for the conversion which includes everything.

Re: Converting SSG to JunOS

That may make sense.  I read the documentation here [1], under section "Converting an SSG 500M-series Security Device to a J-series Services Router".  It says you just need to run 'set boot junos', 'save' in ScreenOS and then swap the CF cards.

 

I couldn't find a list of what is included in the conversion kit:  SSG-550M-J-CONV-S

 

Are you sure the conversion kit includes a eeprom?  I also couldn't find mention of what size CF card is included in the conversion kit.

Re: Converting SSG to JunOS

I have a J4350 to SSG 520M conversion kit and the kit came with the following:

 

  • Sticker/mylar deal to change the front of the device to look like an SSG 520M
  • 512 Mb pre-formatted CF with ScreenOS on it

It looks like the J6350 and SSG 550M are the same hardware per KB16434.

 

I'm looking at the Juniper instructions and the docs are a bit wonky.

 

You would need/want 'set boot junos' if you were leaving the original ScreenOS CF card in the device and wanted to boot the device from a JUNOS formatted CF card.

 

I'm not sure why one would really want to do this when you could just as easily power down the device and swap the internal CF/brain so that the device only contains a JUNOS formatted CF card.

 

You don't really need 'set boot junos' if you are swapping out the internal CF card.

Re: Converting SSG to JunOS

Make sure the SSG550M is running 6.1 and higher.Then get the conversion kit from Juniper(sticker and USB stick)

 

Insert the stick to USB 0

 

set boot junos usb

save

reset

 

Then the device will boot in Junos.
