Grounding the Switch 1. Remove the ground screw from the back of switch, and connect one end of the ground cable to the wiring terminal of switch. 2. Put the ground screw back into the screw hole, and tighten it with a screwdriver. 3. Connect the other end of the ground cable to other device that has been grounded or directly to the terminal of the ground bar in the equipment room. Connecting Power Cord Anti-Trip 1. Force the head of the fixing strap tightly into the hole next to the power socket until it’s buckled on the shell without falling off. In order to protect the power supply from accidental disconnection, it’s recommended to use a power cord anti-trip for installation. Ground Terminal Ground Cable Ground Bar 2. After plugging the power cord into the power outlet, slide the protector over the remaining strap until it slides over the end of the power cord. 3. Wrap the strap of the protective cord around the power cord and lock it tightly. Fasten the straps until the power cord is securely fastened. POWERING & CONNECTING PORT CONNECTING Connect to RJ45 Port 1. Connect one end of the network cable to the switch, and the other end to the peer device. 2. After powered on, check the status of the port indicator. If on, it means that the link is connected normally; if off, it means the link is disconnected, please check the cable and the peer device whether is enabled. Crystal head Ethernet RJ45 RJ45 port RJ45 port Connect to SFP+ Port The installation process of the fiber module is as follows: 1. Grasp the fiber module from the side and insert it smoothly along the switch SFP+ port slot until the module is in close contact with the switch. 2. When connecting, pay attention to confirm the Rx and Tx ports of SFP+ fiber module. Insert one end of the fiber into the Rx and Tx ports correspondingly, and connect the other end to another device. 3. After powered on, check the status of the port indicator. If on, it means that the link is connected normally; if off, it means the link is disconnected, please check the cable and the peer device whether is enabled. Notes: • Please select the optical fiber cable according to the module type. The multi-mode module corresponds to the multi-mode optical fiber, and the single-mode module corresponds to the single-mode optical fiber. • Please select the same wavelength optical fiber cable for connection. • Please select an appropriate optical module according to the actual networking situation to meet different transmission distance requirements. • The laser of the first-class laser products is harmful to eyes. Do not look directly at the optical fiber connector. Fibe…
