<div><br></div><div style>Several years ago, we had Catalyst 2950 switches connected to the integrated Gigabit switches in Dell PowerEdge 1655MC blade chassis. If the blade chassis and switch were powered up simultaneously (a common occurrence when recovering from frequent power/UPS/generator failures in a third world call center), the ports on the 2950 that connected to the 1655MC would invariably fail the loopback tests during POST and be disabled until the 2950 was power cycled, at which point the ports on the 2950 would come up fine. My conclusion was that something about the state of the Ethernet interfaces in the 1655MC during *its* bootup phase caused the 2950 loopback POST sequence to freak out. Once the blade switch was fully booted, the 2950 POST sequence would pass without incident.</div>
