i2C cable for ISR9024D

I have a used (ebay) Voltaire ISR9024D switch, and need to connect to the console to configure it. The switch is presumed to be working, but not confirmed. I don’t yet have HCAs in place to test it, so I want to get into the console to reset the configuration from whatever the previous owner had set up. The only 9-pin connector on this model is an i2C connection, not RS232.

The Installation manual gives a pinout for RS232 (2=Tx, 3=Rx, 5=Gnd), and I’ve wired up a cable accordingly, but we get nothing on the console. So I’m wondering if the pinout on the i2C connection is different?

We’re trying to connect from an old Win2k machine (only because it’s the nearest one to the switch that has a COM port on it), and have tried Putty, RealTerm and HyperTerminal - nothing from any of them. At this point, we’ve tried a rollover cable, a straight-thru cable, and one matching the pinout from the manual. Am I missing something here?

Tonight I’m bringing the switch home to play with there. I’ve only got a Mac laptop, so I’ll be using a USB->Serial adapter. Hopefully that will work. In the mean time, can anyone point me to a known working console cable (or pinout) for this switch?

Thanks!

Hi,

The Voltaire ISR9024D is an unmanaged switch so a console cable will not work.The I2C port is for factory use only for direct interogation/programing of internal devices off the I2c buss.In sort there is no configuration needed on this switch.All you need is to connect it to a host or switch that can run a SM (subnet manager) that can assign and initialize the links on it and any host connected to it.Hope this helps

Hmm. Well, that makes sense. So all I need to do then is get one machine set up with an HCA and the SM I’m going to use, and it does all the configuration over IB?

Is the 10/100 ethernet used for anything on this model?

Thanks!

The managed model would be 9024-M below are some “temporary” links I published for you.One is a 9024 install guide the other is quick start guide covering various models including the 9024 switch.Hope it helps.
