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.
