Ports can conveniently be patched using drag&drop. Open the cabinets you want to patch in between and select an idle port (colored blue). Drag it onto another idle port you want to connect it to. After you choose a patch cable you can finish the process. You can also change connections, which have already been established. Drag a patched port onto an idle port for the idle port to take over the connection from the patched port. The other end of the patch connection is not changed. |
