If the E1 is configured as a PRI you need to remove the pri-group before using the channel-group command.
#Rj45 loopback serial#
To run the loopback test on channelized E1s (PRI or CAS) we need to use the channel-group E1 controller command to create one or more serial interfaces mapped to a set of timeslots in the channelized E1. Use the write memory command to save your router configuration. Insert the plug into the port in question. Twist the wires from pins 9 and 8 together.Ĭomplete these steps to prepare for the extended ping test: Twist the wires from pins 2 and 15 together. Use wire cutters to cut a working DB-15 cable that is 5 inches long with a connector attached. Creating the Loopback Plug for E1 on DB-15Ĭomplete the following steps to create a loopback plug for E1 on DB-15: Refer to the document on RJ-45 cables for more information. With the metal pins facing toward you, and the cable hanging down, pin 1 is the left-most pin. The pins on an RJ-45 jack are numbered from 1 through 8. Twist the wires from pins 2 and 5 together. Twist the wires from pins 1 and 4 together. Use wire cutters to cut a working cable that is 5 inches long with a connector attached. Creating the Loopback Plug for E1 on RJ-45Ĭomplete the following steps to create a loopback plug for E1: If you are working in a live network, ensure that you understand the potential impact of any command before using it. All of the devices used in this document started with a cleared (default) configuration. The information presented in this document was created from devices in a specific lab environment.

The information in this document is based on the software and hardware versions below. There are no specific prerequisites for this document. Before You Begin Conventionsįor more information on document conventions, see the Cisco Technical Tips Conventions. If a router passes a hardware loopback plug test, then the problem exists elsewhere on the line.

#Rj45 loopback password#
Enter username 'root' and password 'default'. The console server will request a username and password. Log on to the console server by pressing 'return' a few times.

If you are using "HyperTerminal" or a similar program running on a Windows PC as the terminal device, then the cable is made up from a Cat5 UTP (440016) cable and two DB-9 to RJ-45 adapters (319001) Plug a serial cable between the console server local DB-9 port and terminal device.Power up the console server and configure the serial connection of the "terminal" device/program you are using to 9600bps, 8 data bits, no parity and one stop bit.custom made RJ-45 Ethernet loopback plug (refer the ELB section at end of this faq).custom made R-45 serial loopback plugs (the SLB section at end of this faq shows the SLB required for a console server with Opengear classic pinout).To undertake these tests you'll need to have at hand: This test enables you to test the console server serial ports and your serial cabling. The Loopback Test also undertakes an Ethernet loopback that senses the data transmitted is received properly.
The loopback program senses that data sent is received properly and that signals set and received properly. When undertaking a Loopback Test, each of the serial ports loop data transmitted to data received, RTS to CTS, and DTR to DSR + DCD. For example the Serial Ports panel will then show you the status of each serial port.Īlternately you can get this serail port status information from the command line by typing pmshell –signals –l port1 Hardware loopback testing the portsĮach console server has Loopback Test facilities built in. You can verify that devices are attached correctly to ports by navigating to the web interface and selecting Status: Statistics.
