Asynchronous Serial Ports
The PRP has two asynchronous serial ports, the console and auxiliary ports. These allow
you to connect external serial devices to monitor and manage the system. Both ports use
RJ-45 receptacles.
The console port provides a data circuit-terminating equipment (DCE) interface for
connecting a console terminal. The auxiliary port provides a data terminal equipment
(DTE) interface and supports flow control. It is often used to connect a modem, a channel
service unit (CSU), or other optional equipment for Telnet management.
Ethernet Ports
The PRP includes two Ethernet ports, both using an 8-pin RJ-45 receptacle for either IEEE
802.3 10BASE-T (10 Mbps) or IEEE 802.3u 100BASE-TX (100 Mbps) connections.

Line Cards
The Cisco 12012 is shipped from the factory with up to 11 installed line cards that provide
a variety of network media types (based on your order). The line cards are installed in slots
0 through 11 in the upper card cage and interface to each other and to the RP through the
switch fabric (cards in the lower card cage). Vertical cable-management brackets attach to
each line card to manage and organize the network interface cables.
