EX-series Switch—Console Port Connector Pinout Information
The console port on the rear panel of an EX-series switch chassis has an RJ-45
connector. Table 20 on page 34 provides the pinout information for the RJ-45 chassis
console connector. An RJ-45 cable and an RJ-45 to DB-9 serial port adapter are
supplied with the switch.
NOTE: If your laptop or PC does not have a DB-9 male connector pin and you want
to connect your laptop or PC directly to an EX-series switch, use a combination of
the RJ-45 to DB-9 female adapter supplied with the switch and a USB to DB-9 male
adapter.
