Chapter 3 Installing the Router

IOS Software Configuration for the Router

As the router boots the Cisco IOS software image, the console screen displays a system banner similar to the following:

Cisco Internetwork Operating System Software IOS (tm) GS Software (GSR-P-M) 12.0(20020120:204554)

.

Note The system banner that appears depends on the image version of the

Cisco IOS software that the system is running.

If the ROM monitor prompt (rommon>) appears on the system console, your router did not find a valid system image, or the boot sequence was otherwise interrupted, and the system entered read-only memory (ROM) monitor mode.

To boot a Cisco IOS software image manually, enter the boot command on the system console. For information on using the various forms of the boot command, see the following sections:

•Locating a Valid Cisco IOS Software Image, page 3-47

•Booting from the Cisco IOS Software Image, page 3-48

PRP Interfaces Using the PRP LEDs

The PRP faceplate has eight device or port LED activity indicators. (See Figure 3-24.) 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 by the RJ-45 Ethernet connectors. Each connector includes four LEDs that indicate link activity (LINK), port enabled (EN), data transmission (TX), and data reception (RX).

•Two Ethernet port-selection LEDs labeled PRIMARY. These two LEDs, when on, identify which of the two Ethernet connections is selected. Because both ports are supported on the PRP, the LED on port ETH0 is always on. The ETH1 LED goes on when it is selected.
