55 Installation 1. Operating Environment ER-5390S must be installed and operated within the limits of specified operating temperature and humidity (see previous section under Specifications). Do not place objects on top of the unit. Do not obstruct any vents at the sides of the unit. Do not position the hub near any heating source such as heater, radiator, or direct exposure to sun. Prevent entering of water and moisture into the unit. If necessary, use dehumidifier to reduce humidity. 2.
4. Connecting to network devices with coaxial cables Attach the T-connector to the BNC port on the rear panel and connect the coaxial cables to the both open ends of the T-connector as illustrated in Figure 5-2. If the ER-5390S is at either end of the coaxial segment, make sure terminate the open end of T-connector with a 50-ohm terminator. Note : Do not connect coaxial cable directly to the BNC port without using Tconnector. OUT Uplink IN 8 7 6 5 4 3 2 1 Figure 5-2 connect the coaxial cables 5.
66 Trouble-shooting 1. Power LED is not lit l Check if the external power adapter is plugged into the power outlet. Make sure the DC power jack is firmly plugged into the power socket of the hub. 2. LNK/Rx LED is not lit after connecting to an active workstation l Check the power switch of the network devices attached to the hub; make sure they are turned ON. l Check the network cable; make sure it is properly connected to the hub and the network device.
5. Collision LED is constantly flashing l Remove all the network cables; connect the cables back one by one to isolate the source of the collision. l Check the network cable, inferior cable quality will result in excessive collision and error packets. [!] Contact your dealer if problem persist.
