Hi,

I have a 384Gbps Switcihgin Fabric Module with 2 XFP Ports.  When booting it is not displaying the boot menu, just a load of what look like errors (below).  Anyone seen this or have any ideas?  I'm wondering if the flash is corrupt but I'd still get the boot menu right?  Bootrom corrupt?  Is there any way of reflashing or reconfiguring when in a none boot state and no access to the boot menu?

Starting......
Press Ctrl+D to access BASIC BOOT MENU

After this it just sits there doing nothing further...  Hope someone out there can help...

Hi rafter

Are you pressing CTRL-D to get the menu?

If you are, and still not getting the menu - then...

You could try some lowlevel trial and error options, like

 - Removing (if any installed) all linecards

 - Reseat the MPU

 - Try a different chassis if you have one.

 Other than that, you have a status "status = 0000000000400002", caused by

"cause = 0000000000008030". And some other coprocessor0 register values,  which are all part of the MIPS exeption handling.  You can convert these to binary and  you can google around to get wiser on that - but I'd start looking into my RMA-options on the MPU.

Regards

Thanks Soren for the response.

I have managed to get into the menu some of the times, although when I dont the errors are as I've posted, although the cause I've also seen FFFFFFFF80008014.

When I have managed to get into the menu, I have successfully formated the flash and put the latest .app on, but when it boots it freezes at random points.  I've also had it freeze just in the menu too.  When it displays a dump I have to leave it out a while then reseat it and hope I have another go!

This is a slave card for another identical card that is working at present.  I've tried in another chassis without success too..

Any ideas where I can find out what these codes mean?

Cheers!!

Call HP for a RMA, they should be able to guide you over the phone if this can be fixed (with some proper keyboard commands) or if the unit is bricked and needs to get replaced.

Hi Rafter,

The MIPS64 architechture can be googled and found various places i reckon, e.g:

http://scc.ustc.edu.cn/zlsc/lxwycj/200910/W020100308600770617815.pdf

in there you can read about exception handling, the coprocessor,  etc ... so if you have some time on your hands its quite interesting -

Still tho - go for the RMA.
