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.

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. 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
