7 Verifying Your Installation
You can verify that you have correctly installed your router by checking the LEDs as described in Table 1.
8 Obtaining Documentation
Cisco documentation and additional literature are available on Cisco.com. Cisco also provides several ways to obtain technical
assistance and other technical resources. These sections explain how to obtain technical information from Cisco Systems.
Table 1 LEDs That Verify Installation
LED Panel What to Look For
PWR Front On when power is being supplied to the router.
OK Front On when the router software is loaded and
functional.
Blinking when the router is running a power-on
self-test (POST). Continual blinking can indicate a
problem with the router, although the LED will
also blink if the router is in ROMMON mode.
Refer to the “Troubleshooting” chapter in the
Cisco 1711 and Cisco 1712 Security Access
Routers Hardware Installation Guide for more
information.

Ethernet network through the 10/100 Ethernet

FDX Back On when the Ethernet port is operating in
full-duplex mode.
100 Back On when the 10/100 Ethernet port is operating at
100 Mbps.

Ethernet LAN.
WIC1 ACT Front Blinking when data traffic is being sent to or
received on the card in the WIC1 slot.
WIC0 ACT Front Blinking when data traffic reaches the host CPU.

(CDP), Spanning-Tree Protocol (STP),
inter-virtual local area network (VLAN) traffic,
and traffic that is routed between the switch ports
and WIC0 and/or the onboard Fast Ethernet port.
Switch port ACT Back On solid when data packets are being transmitted
or received in and out of the Ethernet port.
Off when there is no data activity.
Switch port LNK Back On solid when link is present.
