Ethernet Ports and Status LEDs
The RP has two 8-pin media-dependent interface (MDI) RJ-45 Management LAN ports for 10 Mbps,
100 Mbps, and 1000Mbps Ethernet connections. These ports are labeled MGT LAN 0 and MGT LAN 1.
The transmission speed of the Ethernet port is not user-configurable. You set the speed through an
auto-sensing scheme on the RP, the speed is determined by the network to which the Ethernet port is
connected. However, even at an auto-sensed data transmission rate of 100 Mbps, the Ethernet port can
only provide a usable bandwidth of substantially less than 100 Mbps. You can expect a maximum usable
bandwidth of approximately 12 Mbps when using an Ethernet connection.
These LEDs on the front panel indicate traffic status and port selection (see Figure 4-3):
•LINK—Indicates link activity.
•ACT—Indicates which Ethernet port is selected (ETH 0 or ETH 1).
Note Because both ports are supported on the RP card, MGT LAN 0 is always on. MGT LAN 0 lights
when it is selected.

Auxiliary and Console Ports
The auxiliary and console ports on the RP are EIA/TIA-232 (also known as RS-232) asynchronous serial
ports connect external devices to monitor and manage the system:
•Auxiliary port—RJ45 interface that supports flow control and is often used to connect a modem, a
channel service unit (CSU), or other optional equipment for Telnet management.
•Console port—Receptacle (female) that provides a RJ45 interface for connecting a console terminal.
