Connecting the Cables

Apr 05, 2011

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.

Danger: 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 Ethernet Cables

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 or 1G SFP copper transceiver. Use a fiber optic cable with an LC duplex connector with a 1G SFP fiber transceiver, 10G SFP+, or XFP transceiver. The type of connector at the other end of the fiber optic cable depends on the port of the device that you are connecting to.

To connect an Ethernet cable to a 10/100/1000BASE-T port or 1G SFP copper transceiver

  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.
    Figure 1. Inserting an Ethernet cable


  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.

To connect the Ethernet cable to a 1G SFP fiber, 10G SFP+, or XFP transceiver

  1. Remove the dust caps from the transceiver and cable.
  2. Insert the LC connector on one end of the fiber optic cable into the appropriate port on the front panel of the appliance.
  3. Insert the connector on the other end into the target device, such as a router or switch.
  4. 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. Alternatively, you can use a computer connected to the network. 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.
    Figure 2. Inserting a console cable


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

Connecting the Power Cable

An MPX 5500, MPX 5550/5650, MPX 7500/9500, MPX 8005/8015/8200/8400/8600/8800 appliance has one power cable. All the other appliances come with two power cables, but they can also operate if only one power cable is connected, except the MPX 22040/22060/22080/22100/22120 and MPX 24100/24150 platforms which come with four power cables and require two power cables for proper operation. A separate ground cable is not required, because the three-prong plug provides grounding.

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.
    Figure 3. Inserting a power cable


  2. Connect the other end of the power cable to a standard 110V/220V power outlet.
  3. If a second power supply is provided, repeat steps 1 and 2 to connect the second power supply.
    Note: The MPX 9700/10500/12500/15500, MPX 11500/13500/14500/16500/18500/20500, MPX 11515/11520/11530/11540/11542, MPX 17500/19500/21500, and MPX 17550/19550/20550/21550 appliance emit 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.
