Console and Auxiliary Port Connection Equipment
The NPE contains the console and auxiliary ports. The console port is a RJ-45 receptacle for connecting
a data terminal, which you use to configure the interfaces and bring up the Cisco uBR7255VXR router.
The auxiliary port is a RJ-45 receptable for connecting a modem or the other DCE device (such as a
channel service unit/data service unit [CSU/DSU]) to the router. (See Figure3-12 on page 3-14.)
Note Both the console and auxiliary ports are asynchronous ports; any devices connected to these ports must
be capable of asynchronous transmission. (Asynchronous is the most common type of serial device; for
example, most modems are asynchronous devices.)
