The following steps let you connect the switch to a protective ground: 

Step 1: Verify if the system power is off. 
Step 2: Use the ground cable to place the #8 terminal lug ring on top of the ground-screw opening, as 

seen in the figure below. 

Step 3: Insert the ground screw into the ground-screw opening. 
Step 4: Using a screwdriver, tighten the ground screw to secure the ground cable to the switch. 
Step 5: Attach the terminal lug ring at the other end of the grounding cable to an appropriate grounding 

stud or bolt on rack where the switch is installed. 

Step 6: Verify if the connections at the ground connector on the switch and the rack are securely 

attached. 

 

 

3.4 Plugging in the AC Power Cord 

Users may now connect the AC power cord into the rear of the switch and to an electrical outlet (preferably one that 
is grounded and surge protected).   

 

Power Failure 

As a precaution, the switch should be unplugged in case of power failure. When power is resumed, plug the switch 
back in.   
 

3.5 Connecting Ethernet Interface 

Use switch’s UTP to connect to other Ethernet terminals. Refer to the following chart:   

 

 
UTP port explanation for Fast Ethernet is shown as follows:
