User manual QSC AUDIO QE16 0 10BASET HUB

[. . . ] Hub Features (see diagrams on previous page) Power LED Indicates the hub has AC power and is turned on. Collision LED Indicates a packet collision. Link/Activity LED A steady green light indicates a good cable link between the hub and the network device connected to that port; A blinking green light indicates network activity. [. . . ] · Performs full 10 Mbps Ethernet multi-port repeater functions and complies with IEEE 802. 3 standard for 10BASET Unshielded Twisted Pair (UTP) and 10BASE2 Thin Coaxial (BNC) or 10BASE5 Thick Coaxial (AUI). Specifications: · Industry standards: · Interface: · Uplink port: Complies with IEEE 802. 3, 10BASET standard, FCC Class A, CE Mark. 16 station ports for clients, servers, or other hubs. A designated Uplink port allows cascading to another hub. Requires UTP cable (Category 3, 4, or 5). When cascading using this port, the maximum segment length is 5 meters. · Power supply · Environment: Internally auto-sensing from 90 VAC to 250 VAC. Power consumption is 50 W maximum. Operating temperature: 0° C to 50° C; (Storage temperature: -20° C to 70° C); Operating humidity: 10% to 80% RH; (Storage humidity: 5% to 91% RH). [RH = Relative Humidity]. · Physical dimensions: · Weight: · Safety: LED Indicators 107 × 482 × 44. 4 mm [L (depth) × W × H]; 1 RU rack-mountable 3 kg. (6. 5 lb. ) LVD certified. The QSC QE 16/0 Ethernet hub uses front panel LED indicators to display its operating status: power on, link & activity status, and collision. The LEDs can function as useful troubleshooting aids. Troubleshooting The table below lists the LED indicators of the QE 16/0, what they should display in normal operation, and what might cause an abnormal indication. LED Indicator Power (green) Normal indication On What it tells you If it's not on: 1. ) Make sure the AC power cord is properly inserted into the hub and the AC outlet. If the LED glows green steadily, it indicates that the port detects the 10BASET network carrier signal. If the LED flashes, it indicates network activity--i. e. , the port is transmitting or receiving data. If the LED flashes, it indicates that 2 or more network nodes have tried to access the network simultaneously. Occasional occurrences are normal and will not affect network performance.
