Stacking Dell PowerConnect 7000 Series Switches
Page 4
#Figure 2 shows a recommended stacking configurati on with dual stacking modules on each switch. Ea ch
switch connects to another with 128 Gbps of total bandwi dth (4 ports @ 16 Gbps Tx and Rx each). Note
that in the recommended configuration, the dual stacki ng cables from each module both connect to
the same switch. In the not-recommended config uration, the dual stacking cables on switch 2, modu le
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 t o a single module on each end as shown in the
recommended configuration in #Figure 2.
