Serial Management Port

The serial management port on the Acme Packet 3900 rear panel the provides console access to the unit over an RS-232C serial connection. The serial management port is useful for customers who want permanent console access, and provides a layer of physical security for the unit if access to the site is controlled.

Console port communication is used for administration and maintenance purposes from a central office (CO) location. Tasks conducted over a console port include:
  • Creating the initial connection to the Acme Packet 3900
  • Accessing and using all functionality available via the ACLI
  • Performing in-lab unit maintenance

Serial Management Port Pin-out

The Acme Packet 3900 console port features one RJ45 port on the unit console. Because the Acme Packet 3900 does not employ any type of flow control on its RS-232 ports, only the RX, TX, and GND pins are used. The following table identifies the pin assignments and signal names/descriptions for the console connector.

Console Adapter

A standard RJ45 to DB-9 serial console adapter is shipped with the Acme Packet 3900. This adapter converts the RJ45 plug on a straight-through Ethernet cable to a standard DB-9 serial port jack, found on a PC or laptop. Any straight-through Ethernet cable can be used between the Acme Packet 3900 and the console adapter.Image showing console adapter
