c.Check the cable for continuity.

d.Check that the twisted pair connection meets dB loss and cable specifications outlined in Appendix C, Ethernet Cabling Requirements.

4.If you still cannot establish a link, contact Cabletron Systems Technical Support.

To remove the RJ45 connector from the port once it is locked in, grasp the cable where it enters the network device. Using your finger or a non-conductive probe (the cap of a ballpoint pen is a useful tool for recessed ports) pinch the exposed arm of the locking clip towards the main body of the housing. When the arm contacts the housing, the locking clip has been disengaged. Without releasing the arm, gently pull the RJ45 connector directly out of the port.

If the connector will not come out, there may be damage to the locking clip. Examine the arm of the locking clip. While pressing the arm back toward the shell of the connector, verify that the clip, located within the port, is being moved. If the clip is broken, you may need to use a non-conductive probe to disengage the locking clip.

Do not place foreign objects into device ports while they are connected to a power source.
