The console port on a Juniper Networks device is an RS-232 serial interface that uses an RJ-45 connector to connect to a management device such as a laptop or a desktop PC. If your laptop or desktop PC does not have a DB-9 plug connector pin and you want to connect your laptop or desktop 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.

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.

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. The 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 meet the following requirements:

• USB 2.0 or later

• Formatted with a FAT32 or MS-DOS file system

Table 8 provides the alarm port pinout information on ACX710 routers.

The time-of-day port labeled TOD on the front panel of the router is composed of two electrical interfaces that provide both TOD and 1PPS signals on the same port.

Table 9 provides the TOD port pinout information on ACX710 routers.

1	CONTROL- / 1PPS_LOOP_O UT-	GPS receiver control or 1PPS loop out negative	1PPS_LOOP_IN -	1PPS loop in negative
2	CONTROL+ / 1PPS_LOOP_O UT+	GPS receiver control or 1PPS loop out positive	1PPS_LOOP_IN +	1PPS loop in positive
3	1PPS_IN-	RX 1PPS negative	1PPS_OUT-	TX 1PPS negative
4	GND	GND	GND	GND
5	Power supply/ 10Kohm to GND	Power supply or 10Kohm to GND, depends whether remote connection is GPS receiver or node	10Kohm to GND
6	1PPS_IN+	RX 1PPS positive	1PPS_OUT+	TX 1PPS positive
7	RX-	RX TOD time message negative	TX-	TX TOD time message negative

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.
