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. Connecting to network devices with UTP cable
Connect one end of the network cable to any of the RJ-45 ports on the rear panel, and connect the other end of the network cable to the RJ-45 port of the network device. The network cables must comply with EIA/TIA 568 specifications and minimum Category 3 standard for 10Mbps data transmission. Maximum length between the hub and workstation is 100 meters (300ft). Once the network cable is connected on both ends and the attached network devices are powered on, the green LNK/Rx (Link Status) LED should be lit.

3. Uplink to Another Hub with UTP cable
Use uplink port to connect to another hub as illustrated in Figure 1-2. Connect one end of the network cable to the uplink port and connect the other end to any of the regular port in the other hub (except the uplink port). Connecting cable must comply with EIA/TIA 568 specifications and Category 3 standards to connect the hubs. Once the network cable is connected and both hubs are powered on, the green LNK/Rx (Link Status) LED should be lit. Do not use the uplink port and 8th port at the same time.
NOTE : The maximum length of the uplink cable shall not exceed 100 meters (300 feet).
