If you are mixing a variety of SuperStack® 3 Switchand Hub units, the smaller units must be positioned at the top.If you are placing Switch units one on top of the other, you must use theself-adhesive rubber pads supplied. Apply the pads to the underside ofeach Switch, sticking one in the marked area at each corner. Place theSwitch units on top of each other, ensuring that the pads of the upperunit line up with the recesses of the lower unit.Stacking Units Up to four Switch 4200 Family units can be stacked together and thentreated as a single manageable unit with one IP address. Anycombination of Switch 4200 Family units is allowed in a single stack. Theunits are connected together via the 10/100/1000BASE-T ports on thefront of the unit as shown in Figure 6. Starting from the base of the stack,the port marked with ‘up’ is connected to the port marked with ‘down’on the unit above. Cable lengths of between 14 cm (5.5 in) and100 m (328 ft) can be used for stacking.Figure 6 Stacking exampleThe unit LEDs will display the unit number in the stack, from 1 at thebottom to 4 at the top.3Com recommends that when you add a new unit to a stack, you shouldfirst initialize it to factory default settings.Any Switch 4200 unit can be added to the stack, including the Switch26-Port (3C17300A), the Switch 50-Port (3C17302A) and the Switch28-Port (3C17304A).
