If the Switch is connected to the network, turn off the 
power and disconnect the switch from the main 
power supply and the network.

Place the Switch on a flat, clean, hard, work surface.

Locate and remove the blanking plate that covers the 
slot. See Figure 2-2. Retain the blanking plate and the 
screws for future use.

Use the guide rails within the Switch slot to align the 
module. The location of the guide rails and the cor-
rect positioning of the plate is shown in Figure 2-2. 

Slide the module into the slot without touching the 
top or bottom of the circuit board, which positions 
upside down on the plate. Ensure that the module is 
pushed fully into the unit.

Use the thumb screws attached to the module to fix 
the module firmly into place. 

Connect the cable to the module port.

Each end of the cable has a transmit (Tx) and receive 
(Rx) connector. Connect the Rx connector to the 
port’s Tx socket. Connect the Tx connector to the 
port’s Rx socket. Do the same at the other end of the 
connection.

Power up the switch. The link status LED turns green 
once a valid connection is made.
