IOS Software Configuration for the Router
GRP Interfaces Using the GRP LEDs
The GRP faceplate has eight device or port LED activity indicators. Each LED
goes on when its corresponding PCMCIA slot is accessed. The ports are as
follows:
• Two PCMCIA slot activity LEDs labeled SLOT-0 and SLOT-1.
• Four RJ-45 Ethernet port activity LEDs. These LEDs are used only by the
RJ-45 Ethernet connector, and are disabled when the MII Ethernet port is in
use.
• Two Ethernet port-selection LEDs labeled MII and RJ-45.
When the Ethernet port LEDs are lit, they identify which of the two Ethernet
connections is selected. When the RJ-45 port is selected, that LED is on and the
MII LED is off. When the MII port is selected, that LED is on and the RJ-45 LED
is off. (See Figure 3-23.)

When you start an unconfigured system for the first time, the console screen
displays a system banner and then automatically starts the System Configuration
Dialogue. Observe the Cisco IOS banner on the console screen. If a Flash memory
card containing a valid Cisco IOS software image is inserted in PCMCIA slot 0
and the software configuration register is set to 0x0102 (the factory default
setting), the router automatically boots using this image.
