Connecting the Cables

Aug 09, 2017

When the appliance is securely mounted on the rack, you are ready to connect the cables. Ethernet cables and the optional console cable are connected first. Connect the power cable last.

 

Warning

Before installing or repairing the appliance, remove all jewelry and other metal objects that might come in contact with power sources or wires. When you touch both a live power source or wire and ground, any metal objects can heat up rapidly and cause burns, set clothing on fire, or fuse the metal object to an exposed terminal.

Connecting the Appliance to the Network

Ethernet cables connect your appliance to the network. The type of cable you need depends on the type of port used to connect to the network. Use a category 5e or category 6 Ethernet cable with a standard RJ-45 connector on a 10/100/1000BASE-T port.

To connect an Ethernet cable to a 10/100/1000BASE-T port

  1. Insert the RJ-45 connector on one end of your Ethernet cable into an appropriate port on the front panel of the appliance, as shown in the following figure.

2. Insert the RJ-45 connector on the other end into the target device, such as a router or switch.

3. Verify that the LED glows amber when the connection is established.

Connecting the Console Cable

You can use the console cable to connect your appliance to a computer or terminal, from which you can configure the appliance. Before connecting the console cable, configure the computer or terminal to support VT100 terminal emulation, 9600 baud, 8 data bits, 1 stop bit, parity, and flow control set to NONE. Then connect one end of the console cable to the RS232 serial port on the appliance and the other end to the computer or terminal.

To connect the console cable to a computer or terminal

  1. Insert the DB-9 connector at the end of the cable into the console port that is located on the front panel of the appliance, as shown in the following figure.

2. Insert the RJ-45 connector at the other end of the cable into the serial port of the computer or terminal.

 

Note

To use a cable with an RJ-45 converter, insert the optional converter provided into the console port and attach the cable to it.

Connecting the Appliance to a Power Source

The SD-WAN 4100/5100 SE appliances have two power supplies, with one serving as a backup. A separate ground cable is not required, because the three-prong plug provides grounding. Power up the appliance by installing one or both power cords.

To connect the appliance to the power source

  1. Connect one end of the power cable to the power outlet on the back panel of the appliance, next to the power supply, as shown in the following figure.

3. Connect the other end of the power cable to a standard 110V/220V power outlet.

4. Repeat steps 1 and 2 to connect the second power supply.

Note

The appliance emits a high-pitched alert if one power supply fails or if you connect only one power cable to the appliance. To silence the alarm, you can press the small red button located on the back panel of the appliance.
