Connecting Devices To The Switch - Dell PowerConnect 3048 User Manual

32 Installation
To set up a stacked configuration, it is recommended that all the Low
Voltage Differential Signaling (LVDS) cables are connected before the
power cables are plugged in. The root switch will begin the daisy chain with
an LVDS cable routed from the "out" of the root switch to the "in" of the
leaf switch. Make sure the root switch does not have an LVDS cable
connected to its "in" port. The tail leaf must not have an LVDS cable
connected to its "out" port. Once the LVDS cables have been connected,
proceed to plug in the power cables of the switches, beginning with the last
leaf and working your way toward the root switch. Once the root switch's
power 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 cable
is necessary.
Installation must be done using an RS-232 connection to a computer. It is
recommended that the switch be kept off the network until proper IP
settings have been set. Install and set up the system by following the steps
located under "Connecting the Console
