Figure 2-5 Alternate Option Card - Four Port NIU
USB
The USB port is reserved for software-enabled applications. The USB port is located in
the rear left side of the chassis. The USB port is for Acme Packet use only and is not
to be used by the customer.
Console Port
The Option Card port, located on the rear left side of the chassis, provides console
access to the Acme Packet 6300/6350 over an RS-232C serial connection. The
console port is useful for customers who want permanent console access to the Acme
Packet 6300/6350.
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 6300/6350
• Accessing and using all functionality available via the ACLI
• Performing in-lab system maintenance
Console Port Pin-out
The Acme Packet 6300/6350 System console port is accessed through the RJ45 jack
in the rear of the system. Because the Acme Packet 6300/6350 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.
