| Marketing Information | This cable is used between the top and bottom units of a stack of 3Com SuperStack 3 Switch 3870 switches, so as to add resiliency to the stacking.
Each SuperStack 3 Switch 3870 has two built-in 10Gbps stacking ports at the rear of the unit. For non-resilient stacking, a SuperStack 3 Switch 3870 Stacking Cable goes from the first stacking port of one switch to the second stacking port of the next switch, in and out, switch to switch, down the stack. This Resilient Stacking Cable then completes the stacking loop by connecting the top switch's available stacking port to the bottom switch's available stacking port.
