Connecting a Switch to a Power Supply
CAUTION: Read the safety information in the Safety and Regulatory Information
as well as the safety information for other switches that connect to or support the
switch.
The PowerConnect 7048R switch has two power supplies for redundant or
load-sharing operation. All other models in the PowerConnect 7000 Series
have one power supply. The
power receptacles are on the back panel.
AC and DC Power Connection
1 Make sure that the switch console port is connected to a VT100 terminal
or VT100 terminal emulator via the RJ-45 to DB-9 female cable.
2 Using a 5-foot (1.5 m) standard power cable with safety ground connected,
connect the power cable to the AC main receptacle located on the back
panel (see Figure 1-15).
3 Connect the power cable to a grounded AC outlet.
4 If you are using a redundant or external DC power supply, such as the
PowerConnect RPS720 or PowerConnect MPS1000, connect the DC
power cable to the DC receptacle located on the back panel (see
Figure 1-15).
