J4350 Inventory Issue

Hello Everyone,

Before asking anything i would like to share my Device info :-

Router:- J4350
Junos:- 9.2R1.10

I was checking my Inventory detail which is:-

Hardware inventory:
Item Version Part number Serial number Description
Chassis JN1187A84ADA J4350
Midplane REV 03 710-014594 AABF8936
System IO REV 01 710-016210 AABE0044 JX350 System IO
Crypto Module Crypto Acceleration

FPC 1 REV 15 750-011148 AJ10360129 FPC
PIC 0 2x E1
FPC 3 REV 13 750-015153 AACW3236 FPC
FPC 5 REV 15 750-011148 AJ10360144 FPC
PIC 0 2x E1
FPC 6 REV 15 750-011148 AJ10360192 FPC
PIC 0 2x E1
Power Supply 0

Above detail clearly shows that there is a PIC card installed in FPC slot 1 & 6 but in reality there is none.

PIC status :-

Juniper@KNG-R2> show chassis fpc pic-status | no-more
Slot 0 Online FPC
PIC 0 Online 4x GE Base PIC
Slot 1 Offline FPC
Slot 3 Offline FPC
Slot 5 Online FPC
PIC 0 Online 2x E1
Slot 6 Offline FPC

Can someone tell me why router inventory report is showing PIC(In FPC slot 1 & 6) but in real there are no PICs installed ?.
Could it be that the device needs a reboot to update its details ?

NOTE:- The device used to have PICs installed but those were removed few months ago.

Thanks

That is some pretty old software you have running there. Could be a bug.

Yea that looks pretty funky. Try a different software version and see if its still there. I powered up one thats been collecting dust and this is my inventory.

Does it still show after a hard reset?

llllvllll

No i have not used hard reset yet , I think its time i should upgrade it's Junos.
BTW can i jump directly to version 10 or i need to install 9.5 then version 10 which will be an issue as Juniper no longer has version 9 OS in their website and i have to open a case for that.

You normally need to upgrade within 3 dot releases, so you may need to make a pit stop at 9.5. Check the release notes for the 10 version you are targeting and they should include guidelines for upgrading from older versions.

You can sometimes go beyond that 3 dot release limit if you're going from an EEoL release to another EEoL release, but those are typically the last dot release in a major version. I'm pretty certain 9.2 is not EEoL. But, for example, 9.6 to 10.4 (assuming I'm remembering my EEoL numbers). Technically, I was even able to do upgrades from 10.4 to 12.1X44 and it falls within the supported guidelines for EEoL upgrades, though some people strongly recommended I stop at 11.4 midway anyways. Oh well.

If you don't feel like tracking down 9.5, you could always do a no-validate and force the install. Obviously the disclaimer is that is not supported/recommended.

Or, you could get the install-media file for the 10 version you want to go to. It will do a full format and install from the removable media and you should be fine. This method will wipe your config, so backup of course.

I guess I should end this with the note that if this is a production router, not lab, and important or critical to your network, you should really follow the official Juniper support recommended processes. I've been a lab rat for too long, so I haven't always followed the correct procedures...

Were the PICs physically removed? Or were the FPC or PICs just powered down? If physically removed, then ya, could be a bug or just needing a reboot.

As luck would have it, I have a J6350 handy to mess with. Remotely. I can't yank hardware. But the behavior in your output matches mine when I just offline a FPC. sh chassis hardware still shows the FPC and PIC installed in the FPC. sh chassis fpc pic-status does not show the PIC however as the FPC is offline.

My code version here is 11.4.

Zoidberg :- Thanks for your input

Yes, PICs were physically removed few months ago. Might be a bug or could be my Junos version. I have already opened a case in Juniper let's see what they suggest.
