Thanks - that's what I thought it should be, I believe its a DB9 to DB9 null modem cable but I'm getting nothing from the terminal - not even during boot, now I am slightly worried that perhaps the switch is bricked - its Mgmt light is flashing but I'm struggling to tell if its amber (bad) or green (post) but its been doing this for over 30mins pretty much as soon as the power cable is plugged in...... I've ordered a null modem cable from the bay just to be sure. PS: My lookout for a nice IB switch landed at this one: http://www.ebay.co.uk/itm/360723489110?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 wow what a bargain, but unfortunately the seller told me that there is no Mellanox software / firmware on the device(s)
