LOOPBACK PLUG TO TEST AN ETHERNET PORT HOW TO

In conclusion, a loopback test is an easy way to confirm that your current hardware is working properly. Loopback created with single fiber strand If the interface fails to receive any test packet, the hardware of the interface is faulty. RP/0/RSP0/CPU0:ASR9001-F show interfaces tenGigE 0/0/1/1 TenGigE0/0/1/1 is up, line protocol is up Interface state transitions: 3 Hardware is TenGigE, address is 65 (bia 65) Layer 1 Transport Mode is LAN Internet address is 10.100.101.1/ bytes, BW 10000000 Kbit (Max: 10000000 Kbit. During the external loopback testing, the port sends out a certain number of test packets, which are looped over the plug and back to the interface. If not, further troubleshooting is necessary. To perform external loopback testing on an Ethernet interface, insert a loopback plug into the port. If lit, the port of hardware is functioning properly. Once the ports are connected review the status of the link light. If using a loopback module the Tx and Rx ports will be connected to each other, if using a transceiver install the isolated ends of the same strand of cabling to the transmit and receive ports of the transceiver.ДЈ. (If testing a module with a 40km or greater reach utilize the appropriate optical attenuator).Дў. Slimline Loopback Test Plugs - Emulate Working Conditions for Your Testing Needs - These slimline loopback testers can help diagnose problems with serial or. Install transceiver or loopback module into switch.

LOOPBACK PLUG TO TEST AN ETHERNET PORT HOW TO

Remove collar and isolate both ends of the same strand of cable How to perform and confirm a loopback test using a single strand of fiber:ДЎ.

Creating a single strand of fiber out of a duplex cable takes a couple of extra steps.Дў. It requires a self-contained loopback module or a single strand of fiber. A loopback test eliminates superfluous connections and confirms that a transceiver or port is functioning properly by connecting the transmitter and receiver of the same module. Insert an ethernet loopback jack or sniffter into the jack.It will detect the Internet connection and give you a proper display light if the jack is working.
