[. . . ] In a fullduplex environment, there is no collision. In a halfduplex environment, some collisions are normal. Packet transmission or reception is occurring on the port. [. . . ] Connect the devices to the network ports on the switch, using 50 µm or 62. 5 µm multimode fiber cables with SC plugs. Note: Ethernet specifications limit the cable length between your PC or server and the switch to 525 m for 50 µm and 260 m for 62. 5 µm fiber. 2. Connect one end of the DC power adapter cable to the power outlet on the rear panel of the switch and the other end of the power adapter cable to the wall outlet. Refer to the following illustration when connecting the switch.

Each fiber link needs a clearly defined, external crossover. In other words, the transmit port of one interface must be wired to the receive port of the opposite interface and vice versa. Fiber cables must be connected in this manner to transmit and receive data. Tx Rx 8895FA Verify Installation When power has been applied to the switch, verify that: · · The green Pwr LED on the front panel is on. The green Link LED on each connected port is on. When the switch is connected and operating, refer to the table in "LEDs" for information about the LEDs and their activity. Model GS504 4-Port Gigabit Switch Installation Guide Troubleshooting Information Symptom Cause Solution Power LED is off. No power is received Check the power cord connections for the at the hub. Make sure all cables used are correct and comply with Ethernet specifications. Link LED is off or Port connection is intermittent. Check the crimp on the fiber connectors and make sure that the plug is properly inserted and locked into the port at both the switch and the connecting device. Make sure all cables used are correct and comply with Ethernet specifications. Check for a defective adapter card, cable, or port by testing them in an alternate environment where all products are functioning. Make sure the remote link partner is set to autonegotiate or forced to full-duplex operation. File transfer is slow or performance degradation is a problem. A segment or device is not recognized as part of the network. FDX/Col LED is blinking yellow excessively. Half- or full-duplex setting on the NETGEAR switch and the connected device are not the same. One or more devices are not properly connected, or cabling does not meet Ethernet guidelines. Verify that the cabling is correct. Be sure all cable connectors are securely positioned in the required ports. [. . . ] The operation of some equipment (for example, test transmitters) in accordance with the regulations may, however, be subject to certain restrictions. Please refer to the notes in the operating instructions. Federal Office for Telecommunications Approvals has been notified of the placing of this equipment on the market and has been granted the right to test the series for compliance with the regulations.
