ACX7100-48L Management and Console Port Specifications and Pinouts

Table 1 lists the specifications for the cables that connect the console and management ports to management devices.

Table 1: Specifications of Cables to Connect to Management Devices

Ports	Cable Specifications	Receptacle	Additional Information
RJ-45 Console (CON) port	RS-232 (EIA-232) serial cable	RJ-45	Connect a Device to a Management Console by Using an RJ-45 Connector
Management (MGMT) port	Ethernet cable with an RJ-45 connector	RJ-45	Connect a Device to a Network for Out-of-Band Management

The management port—labeled MGMT—on an ACX7100 uses an RJ-45 connector to connect to a management device for out-of-band management.

The port uses an autosensing RJ-45 connector to support a 10/100BASE-T connection.

Table 2 provides the pinout information for the RJ-45 connector for the management port.

Table 2: Management Port Connector Pinout Information

Pin	Description	Direction
1	TRP1+	Transmit/receive data pair 1
2	TRP1–	Transmit/receive data pair 1
3	TRP2+	Transmit/receive data pair 2
4	TRP3+	Transmit/receive data pair 3
5	TRP3–	Transmit/receive data pair 3
6	TRP2–	Transmit/receive data pair 2
7	TRP4+	Transmit/receive data pair 4
8	TRP4–	Transmit/receive data pair 4

The port labeled CON on the front panel is an RS-232 serial interface that uses an RJ-45 connector to connect to a console management device. The default baud rate for the console port is 9600 baud.

Use a cable with the pinouts described in Table 3 to connect an ACX7100 to a console management device.

Note:

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 an ACX7100, use a combination of the RJ-45 cable and RJ-45 to DB-9 adapter and a USB to DB-9 plug adapter. You must provide the USB to DB-9 plug adapter.

Table 3: Console Port and TOD Connector Pinouts for the ACX7100

Pin	Signal	Description
1	N/C	Not Connected
2	DSR Output TOD Output	Data set ready Time of Day (TOD) for Precision Time Protocol (PTP) applications. You can use DSR pins as a TOD universal asynchronous receiver/transmitter (UART) by using a breakout cable.
3	RxD Input	Receive data
4	Signal Ground	Signal ground
5	Signal Ground	Signal ground
6	TxD Output	Transmit data
7	TOD Output	Time of Day (TOD) for Precision Time Protocol (PTP) applications. You can use DTR pins as a TOD universal asynchronous receiver/transmitter (UART) by using breakout cables.
8	N/C	Not Connected

The USB flash drives that you use with the ACX7100 must support USB 2.0 or later.

CAUTION:

Remove the USB flash drive before upgrading Junos OS Evolved or rebooting an ACX7100. Failure to do so could cause the router to behave unpredictably.
