Power On the DC Power Supply
After the router is either rack mounted or mounted on the wall, perform these tasks to complete the installation:
Procedure
Step 1
Power on the DC power supply. See the figure below.

Step 2
Connect the front-panel ports.
Connect Gigabit Ethernet Ports
Gigabit Ethernet (GE) ports can be connected to other devices using either fiber optic or copper cables. The
choice depends on whether the communication distance between your devices is long or short.
If you choose fiber optic cables, connect suitable Small Form-factor Pluggable (SFP) modules. The device
supports various SFP and SFP+ modules, including optical and Ethernet modules. For information on how
to install and remove SFP and SFP+ modules, see the documentation for the SFP or SFP+ module at:
SFP and SFP+ Transceiver Module Installation Notes
. Select the port on the device where you insert the SFP
module.
If you choose copper cables, connect to an RJ-45 connector.
The device 10/100/1000 ports configure themselves to operate at the speed of devices to which they are
connected. By default, autonegotiation is enabled in the chassis. You can manually set the speed and the
duplex parameters. If the device to which the ports are connected does not autonegotiate, low performance
or no linkage may result.
To maximize performance, choose one of these methods for configuring the GE ports:
• Have ports autonegotiate both speed and duplex parameters.
• Set speed and duplex parameters on both ends of the connection.
