Our core switch is not booting after we had a power cut this afternoon. When power was restored I found that the 'Fault' LED [below the power LED] and the the DIM LED [on the console] were both blinking orange about once a second.

 

I am waiting for HP to call me back but if anyone could point me in the right direction as to how to solve this before HP get back that would be great.

 

Thanks.

Take one module out at a time and try turning it on. If its not one of the main modules it could half borked the management card

 

Have you tried plugging into the console port? Might throw some light onto it.

 

Thanks both. These are both ideas that I had not considered [i am not familiar with the switch as it has just sat there and done its job since being installed] Actually I am hoping that the problem is not too serious as it this switch holds our VLan configuration and so without it we are dead in the water. :sad:

If had my old one crash a couple of times randomly. I guess you have already tried the basic power cycle.

 

On the management card there is a rom stick which requires flashing if the management as borked itself, although it should have 2 images on itself to roll back if the first is unusable.

Yes. Tried the power cycle twice. Same result.

Not sure how to do all that. I guess HP will be able to talk me through it? Will I need any hardware to do this? [a specific type of cable etc]

 

Thanks.

Maybe you should look at getting a second core switch? I assume you have redundancies in your servers? Seems a waste if you don't have it in the network :)

Any news Dave?

 

Console port will hopefully throw some light.

 

Else take out all cards and reseat, and if that does not work take out all the line cards and restart.

 

 

Any POE cards? it may bee that the PSU's are over subscribed due to a PSU failure.

Had the same problem years ago...

 

Agree with most of the posts above - take all cards out and reboot the switch. If the switch boots properly, replace the cards one by one, rebooting the switch with each card you put in.

BTW you can backup the HP Procurve's configuration to a text file via tftp or SSH scp.

 

TFTP:

copy run tftp 10.1.1.10 config1.cfg

 

SSH (from a client PC):

 

pscp -scp -l USERNAME -pw PASSWORD -2 192.168.100.1:cfg/running-config c:\switch.cfg

 

 

Assuming you have TFTP/SSH file transfer enabled on your switch (which you should).

you can also download it from the web-interface.

The web interface is bloody awful and I'd suggest you avoid using it where ever possible.

No news. Waiting for HP's call back. Don't want to try anything new until after I have spoken to them [This via my phone]

And we're back! A new Management Module in the core switch fixed it.

 

Now: Business as normal. :D

 

Edit: I typed too soon! All of our fibre connected rooms are having problems. Something to do with the VLans on the fibre module. :censored:

 

Edit 2: Looks like it is all up and running again. Resolution: Take the fibre module out of slot C and put it in slot D. Reconfigure one VLan in favour of the new slot. Tested stations work. Move the fibre module back to slot C configure VLan back to original state and check stations. All found working. Called it a day.

I know it's been a few months, but I thought I throw in this update. Today I experienced the same issue as the OP. I scoured the web and this was the only relevant post I found with no real resolution for me. Here's my story.

 

Restarted my switch today to quickly restart a bunch of PoE phones. The switch never came back up. It flashed the fault light and the DIM light. Tried power cycling, re-seating the management module, removing all modules except the management module, and re-seating all the modules. None of them work. I noticed that there was a CF card and a memory DIMM on the management board. Right above the DIM light is a CF light, so I thought...meh...what the heck, it's already broken. So, I replaced the memory with another one I had spare (replaced the 256MB PC2700U with a 512MB PC2700U DIMM). 'Lo and behold, the switch came back on!!! Thank you God for us being pack rats and having those old memory around!!

 

Anyways, just thought I post this up on here. This solution worked for me and thought it might help some poor soul who stumbles upon this thread. Keep a spare chassis!! It'd be less stressful. :)
