C7000 Strange Hardware Problem!
We replaced the midplane on one of our C7000 enclosures to try and resolve a problem where none of the Virtual Connect modules were visible via the OA.
However, when the enclosure was powered up, we saw all sorts of errors on Insight Display. Thinking this might be a problem with the replacement midplane, we swapped out that one for yet another midplane.
Now the enclosure is completely unusable! The fans are flashing amber LEDs and running at high speed, there is no Insight Display, two PSU bays are showing errors which persist in the same location even if the two "faulty" PSUs are swapped round.
The VC modules are interconnected in pairs, but not communicating with each other. The storage blades I have will initialise OK, but the server blades don't power up on their own, and I can't manually power them up as they don't respond to the button press
We have swapped out the OA tray, and tried the "minimum config" approach by removing all the VC modules, blades and the standby OA in a bid to eliminate the cause of this, all to no avail.
Not being experts with this equipment, my colleague and I are at a loss as to what's happening.... please help!

Re: C7000 Strange Hardware Problem!
have you tried to reflash your OA firmware since you replaced the Midplane? Somtimes the OA firmware contains some firmware for the underlying components as well.
I'm thinking as you replaced the midplane some firmware inside it is to low to function with your current OA FW?

Re: C7000 Strange Hardware Problem!
also on every blade before firmware updates try this
clear nv ram
blade clear nvranm
Clearing the system configuration
To clear the system configuration:
1. Power down the server blade
2. Remove the server blade
3. Remove the access panellook at the diagram on it it will show the position of the maintenace switch( it clears Nv ram)
4. Change position 6 of the system maintenance switch to on.
5. Install the access panel
6. Install the server blade in the enclosure and power up the server blade.
7. Wait for the POST message that prompts you to change the switch setting:
Maintenance switch detected in the "On" position.
Power off the server and turn switch to the "Off" position.
8. Repeat steps 1 through 3.
9. Change position 6 of the system maintenance switch to off.
10. Repeat steps 5 through 7.
This is how we thank in the forum

Re: C7000 Strange Hardware Problem!
I'm thinking that the midplane has developed a fault.
I'll be speaking to HP today & see what they say. I'll update the thread when I have an answer.
Cheeers

Re: C7000 Strange Hardware Problem!
I had this exact same issue, and it was a problem with the Front-to-back assembly that connects the Insight display front panel to to Midplane.
Have you checked to see if there are any problems with the connection from Front to back assy?
Regards
Matt
