Stacking Dell PowerConnect 7000 Series Switches
Figure# 2 shows a recommended stacking configuration with dual stacking modules on each switch. Each switch connects to another with 128 Gbps of total bandwidth (4 ports @ 16 Gbps Tx and Rx each). Note that in the recommended configuration, the dual stacking cables from each module both connect to the same switch. In the not-recommended configuration, the dual stacking cables on switch 2, module B and switch 3, module B connect to two different switches.
NOTE: To ensure full bandwidth when using redundant links between two switches, be sure not to split the links across modules. Keep redundant links isolated to a single module on each end as shown in the
recommended configuration in Figure# 2.
