this really is a Dell question but tempted to ask the experts @ serverfault.

choosen a Dell powerconnect 8024 10GbE switch. per the spec sheet this has 10GbaseT ports.

"24x 10GBASE-T (10Gb/1Gb/100Mb) with 4x Combo Ports of SFP+ (10Gb/1Gb) or 10GBASE-T"

the HBA on my storage server has 10G CX4 copper ports

Dell does not sell any cables and this adds to my confusion.

from the picture Dell 8024 seems to have RJ-45 type ports on the front panel? my question: is it a RJ-45 + CX4 cable or CX4 + CX4 cable?
