32 Installationw w w . d e l l . c o m | s u p p o r t . d e l l . c o m To set up a stacked configuration, it is recommended that all the LowVoltage Differential Signaling (LVDS) cables are connected before thepower cables are plugged in. The root switch will begin the daisy chain withan LVDS cable routed from the “out” of the root switch to the “in” of theleaf switch. Make sure the root switch does not have an LVDS cableconnected to its “in” port. The tail leaf must not have an LVDS cableconnected to its “out” port. Once the LVDS cables have been connected,proceed to plug in the power cables of the switches, beginning with the lastleaf and working your way toward the root switch. Once the root switch’spower cable is connected, the stack of switches will begin to boot up.NOTICE: Never add or remove an LVDS cable when the units are powered on.If you are using just one switch in a nonstack configuration, no LVDS cableis necessary.Installation must be done using an RS-232 connection to a computer. It isrecommended that the switch be kept off the network until proper IPsettings have been set.
