Has Cisco stopped manufacturing the CAB-1309-C19-INT? This power lead is for the 6000W PSU for a Catalyst 4500 chassis. It has a C19 at the switch end and an IEC309 at the supply end, and is about 4m long. My usual Gold Partner can't get hold of any. Does anyone know where I can get some from? They have always been a bit hard to get hold of and were a cost option, but now I can't get them at all.
