Connecting a QFX Series Device to a Management Console
Ensure that you have an RJ-45 to DB-9 rollover cable available. An RJ-45 cable with an RJ-45 to DB-9 adapter is provided with the device.
If your laptop or PC does not have a DB-9 plug connector pin and you want to connect your laptop or PC directly to the QFX Series, use a combination of the RJ-45 cable and RJ-45 to DB-9 adapter supplied with the device and a USB to DB-9 plug adapter. You must provide the USB to DB-9 plug adapter.
The QFX Series has a console port with an RJ-45 connector. Use the console port to connect the device to a management console or to a console server.
To connect the QFX Series to a management console (see Figure 1 and Figure 2):
- Connect one end of the Ethernet cable to the console port (labeled CON).
- Connect the other end of the Ethernet cable into the console server (see Figure 1) or management console (see Figure 2).
