Fuse on Intercon.Switch Blades

I have no power on one of Enclosure's both Intercon. Switches. Both 40p Blade servers are powered on on the same enclosure.
I replaced one of the 'Interconnects', but power is stil off. Checking though web access, clicking on Interconnect Switch I found that one of the fuses is down. Where are these fuses?! In the enclosure or inside the Interconn. switch?! What is troubleshooting procedure?! I did not find it in the Blade documents. Or, simply I missed something.

Re: Fuse on Intercon.Switch Blades

There is a fuse for each slot in the power backplane. Try your switches in another enclosure to make sure they are good.

You may have a bad pwr backplane or signal backplane. YOu can also try swapping these with another enclosure to see which is not working.

Re: Fuse on Intercon.Switch Blades

Check all switches and wiring, check the Power LED for Mini bus bar or Scalable bus bar

Check page 13 for components â reset them
Did you get any light on the back?

Can you see second enclosure trough management links - Power management Module Firmware at least 2.10 or 2.20? and reset after

Fuses is part of backplane on the enclosure, it's not a physical switch or etc ..

Re: Fuse on Intercon.Switch Blades

I tried replacing Intercon. switches - the same No result. Yesterday, on first attempt the Intercon. switches got the power on. However, I intentionally repowered the enclosure and the same problem appeared again, no power on Intercon. switches.
I have 2 racks, 1-st one with 3 p-enclosures, and 2-nd with 2 p-enclosures. As the first rack installation is priority, I swapped that enclosure by good one to keep working on Blade servers.
FW for p-enclosure is 2.20
FW for power enclosure is 2.10
I will test this issue again on 2-nd rack.
