Verifying Your Installation
You can verify that you have correctly installed the router by checking the following LEDs:
Table 2-1 Using LEDs to Verify Installation
Installing a Flash PC Card
The Flash PC card is a writable card used to download new software to the router.
Note Although the router is shipped from Cisco with the Flash PC card already installed,
you might have to install it if someone has removed the card for any reason. For example,
to configure your router, the system administrator might remove the card, add a
configuration file to it, then return it to you.
LED (Location) What to Look for
PWR (front) On steady when power is being supplied to the router.
OK (front) • One blink per second when the router is in ROM monitor
mode.
• Several blinks per second when the router is running the boot
image in ROM monitor.
• On steady when the Cisco IOS software is loaded and
functional.
ETHERNET ACT (front) Blinking when there is network traffic on the local Ethernet
network.
LNK (rear) On steady when the router is correctly connected to the local
Ethernet network through the Ethernet port.
