Rebooted on VPEX Slot and after reboot it stopped delivering PoE Power.The inline-power states of the ports switched to searching and devices that are connectedvia Lan show fault. The show inline-power slot <id> shows correct 740W budget.Replacing the V400 did not help - same issue.
Are there more then 1 VPEX slot? If so, does the behavior follow the other slots?
Also, check to make sure there are no rxerrors on the edge ports and/or the cascade ports with "show ports rxerrors"
