Without powering down the Acme Packet 4500, you can exchange an NIU (for the
same type of card) by removing and replacing it. Upon NIU removal, the Acme
Packet 4500 enters an Out-of-Service state. After you reinsert the NIU and connect
to the ACLI, you must reboot the system to return to service. This causes a soft-
reboot rather than a system power cycle.
Console Port
The console port on the NIU provides console access to the Acme Packet 4500 over
a RS-232C serial connection. The Acme Packet 4500 supports only one active serial
console connection at a time. The rear console port is useful for customers who want
permanent console access; the front console port provides easy access to the Acme
Packet 4500 for a temporary connection.
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 4500
•
Accessing and using all functionality available via the ACLI
•
Performing in-lab system maintenance
Console Port Pin-out
Acme Packet 4500 console ports are accessed through one of the two RJ45 jacks on
the system console. Because the Acme Packet 4500 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 your Acme Packet
4500. This adapter converts from an Ethernet cable’s RJ45 plug to a standard DB-9
