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

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:

RP Discrete LED Display Definitions (continued)
Color
Amber
Green
Red
LINK—Indicates link activity.
ACT—Indicates which Ethernet port is selected (ETH 0 or ETH 1).
Because both ports are supported on the RP card, MGT LAN 0 is always on. MGT LAN 0 lights
when it is selected.
Management LAN Port Activity LEDs
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.
