Please Help!! Connecting various Dell switches..

Hi,

I'm new to the group and networking as well..I've acquired the following equipment.

1 Dell 8032 with 1 QSFP-R Stacking Module 5KFVW

1 Dell 7048R with 2 J3PC9 10 Gbe SFP+Ethernet Module

1 Mellanox SX6036 Switch..

2 Volex QSFP+ to Quad SFP+ 2.0M Passive Cable VAHS-30-0428-2M

6 MC2210130-002. Mellanox Technologies 2M 40GE QSFP Passive Copper Cable 30AWG

I've tried to connect the SX6036 switch to the Dell 8032 5KFVW module via two of the mellanox QSFP cables and I don't get any activity or link lights on either switch. I've also tried connecting the 8032 5KFVW module to 7048R J3PC9 module via the Volex QSFP+ to quad SFP+ cable and the activity leds flash on the 7048R J3PC9 but no activity or link leds on the 8032 5KFVW module..

So am I having issues due to bad configuration on the switches? Incompatibility between the cables? Or can these switches not be connected in this manner.

Being I'm new to the whole networking thing, I was kind of hoping this would be more or less plug n play, but I'm guessing that isn't the case..

Please Help..

Thanks in advance,

Rob
