Hi Apart from the obvious fact that the blade could be broken (and I guess you will have to open a case for this in our GTAC), I would recommend you to check also your electrical supply. By experience, I do know that peaks, instabilities and noise on the electrical network can severely affect PoE subsystems so, check if for example in this blade there is a device attached with a different ground / earth than the rest of the installation or things like that.

We have an N5 chassis with the following blades: Slot Model Serial # Versions ------ ---------------- -------------------- ------------------------- 1 7G4202-30 XXXXXXXXXXXX Hw: 0 Bp: 01.00.15 Fw: 06.11.01.0040 2 7H4385-49 XXXXXXXXXXXX Hw: 0 Bp: 01.00.15 Fw: 06.11.01.0040 3 7H4385-49 XXXXXXXXXXXX Hw: 0 Bp: 01.00.15 Fw: 06.11.01.0040 5 7H4385-49 XXXXXXXXXXXX Hw: 0 Bp: 01.00.19 Fw: 06.11.01.0040 The POE controller on blade 5 keeps resetting, interrupting power to our phones. These resets happen at random, we can go for months then have a couple of resets the same day. We've had these problems for some time now. Data flow on the blade is not interrupted and we have no entries in the error log, we simply loose POE. The blade has already been replaced, which points towards something site specific, I've a few ideas. I've noticed that you now have "show port cablestatus" on the SecureStack series but there does not seem to be an equivalent on the DFE? Is there any way we can find out why the POE controller decides to reset? The only way we can think of narrowing this down is to gradually move devices connected to that blade, to another and see if the fault moves, gradually eliminating the cause. However, because of the random nature of the fault this could take many months to narrow things down. We have about 20 devices drawing power, and the power usage of each device tallies up with the device type. Any suggestions would be greatly appreciated!
