The RP has 8 device or port LED activity indicators that show the status of the
Ethernet connections (
Figure 4-4 ).
Figure 4-4 RP LEDs
The RJ-45 port LEDs on the RP indicate:
• Which Flash memory card slot is active.
– Each LED lights when its corresponding PCMCIA slot is accessed
(SLOT 0 and SLOT 1).
• Which Ethernet connection is in use.
– 4 RJ-45 Ethernet port activity LEDs indicate link activity (LINK), port
enabled (EN), data transmission (TX), and data reception (RX).
• What is occurring on the Ethernet interface.
– 2 Ethernet port-selection LEDs (labeled PRIMARY) identify which of
the Ethernet connections are selected. Because both ports are supported
on the PRP, the LED on port ETH0 is always on. The LED on port ETH1
lights when it is selected.
LINK Indicates link activity
EN Indicates the port is enabled
TX Indicates data transmission
RX Indicates data reception
