ACX2000 and ACX2100 Alarm, Management, and Clocking Cable Specifications and Pinouts

 

Alarm Contact Port Pinouts on the ACX2000 and ACX2100 Router

You can independently configure alarm input ports (0 to 3) to operate in Normally Open or Normally Closed mode, and to trigger a red alarm condition or a yellow alarm condition, or to ignore alarm conditions.

You can independently configure alarm output ports (0 and 1) can be configured to relay alarm information when the system condition goes to a red or yellow alarm condition and when the alarm output port is configured to trigger based on alarm input condition. Alarm output ports (2 and 3) are used to indicate major and minor system alarms and are normally in open mode.

Table 1 shows the alarm contact connector pinouts.

Management Port Connector Pinout Information for ACX Series Routers

The management port— labeled MGMT— on an ACX Series router 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. Two LEDs indicate link activity on the port and the administrative status of the port.

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

Console or Auxiliary Port Connector Pinout on ACX Series Routers

The port labeled CONSOLE/AUX on the front panel is an asynchronous serial interface that accept an RJ-45 connector. Use a cable with the pinouts described in Table 3 to connect the Routing Engine to an auxiliary or console management device.

Note

You must use a shielded twisted pair (STP) cable for both outdoor and indoor deployments.

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

Clocking Ports Specifications on the ACX2000 and the ACX2100 Router

Two sets of clocking ports allow you to connect the ACX2000 and ACX2100 router to external clocking devices.

External Clocking Port Connector Specifications

The external clocking port on the router contains four SMB connectors that support 10 MHz GPS and 1 pulse-per-second (PPS) signals. These signals can also be accessed through the External Clocking Input port. These signals are internally isolated and have surge protection. Use a Molex 50-ohm SMB connector or equivalent (not provided) to connect to the external clocking ports.

External Clocking Input Port Specifications

An external clocking input port labeled EXT REF CLK IN on the front panel of the router allows you to connect external clock signal sources.

The port uses an autosensing RJ-48 connector to support framed T1 or E1 signals. Two LEDs indicate link activity on the port and function in the same way as the T1/E1 ports. The clocking information is extracted from the input, but the data is discarded.

Table 4 provides the pinout information for the RJ-48 connector for the external clocking input port.
