RJ-45 to DB-9 Serial Port Adapter Pinout Information

The console port is an RS-232 serial interface that uses an RJ-45 connector to connect to a management device such as a PC or a laptop. If your laptop or PC does not have a DB-9 pin contact and you want to connect your laptop or PC to the device, use a combination of the RJ-45 to DB-9 socket adapter along with a USB to DB-9 plug adapter.

Table 3 provides the pinout information for the RJ-45 to DB-9 serial port adapter.

Console Port Connector Pinout on ACX710 Routers

The console port on a Juniper Networks device is an RS-232 serial interface that uses an RJ-45 connector to connect to a console management device. The baud rate for the console port must be set to 115200 baud.

Table 4 provides the pinout information for the RJ-45 console connector.

Note

If your laptop or PC does not have a DB-9 pin contact and you want to connect your laptop or PC directly to a device, use a combination of the RJ-45 to DB-9 socket adapter and a USB to DB-9 plug adapter. You must provide the USB to DB-9 plug adapter.

USB Port Specifications for an ACX Series Router

The following Juniper Networks USB flash drives have been tested and are officially supported for the USB port on all ACX Series routers:

  • RE-USB-1G-S

  • RE-USB-2G-S

  • RE-USB-4G-S

Caution

Any USB memory product that is not listed as supported for ACX Series routers has not been tested by Juniper Networks. The use of any unsupported USB memory product could expose your ACX Series router to unpredictable behavior. Juniper Networks Technical Assistance Center (JTAC) can provide only limited support for issues related to unsupported hardware. We strongly recommend that you use only supported USB flash drives.

All USB flash drives used on ACX Series routers must have the following features:

  • USB 2.0 or later

  • Formatted with a FAT or MS-DOS file system

The TOD output mode is used for monitoring and measuring the accuracy of Precision Time Protocol (PTP) recovered time and phase, and can also be used to provide time and phase information to downstream devices. In the TOD input mode, the telecom boundary clock (T-BC) synchronizes its local clock to the GPS, and distributes time and phase information to downstream PTP devices.
