Cisco Systems CISCO7201 Manual De Usuario

The procedures in this section assume that you have not made changes to your configuration file.

If the Cisco 7201 router I/O LEDs (LINK/ACTV, EN, USB, FE 0/0, CF ACTV) do not go on as expected 
(see the 

), check the following items to help isolate 

the problem:

The processor subsystem comprises the system board and the port adapter. A port adapter that is partially 
connected to the system board sends incomplete signals to the processor, which faults the PCI bus and 
causes the system to pause indefinitely. Therefore, first ensure that the system software has initialized 
successfully and then check to see if the port adapter is fully connected.

LEDs remain off when the 
system power switch is turned 
on.

Power supply or 
cooling 
subsystem is 
faulty.

If the LEDs stay off, first see the 

 and the 

 to 

ensure that both the fans and the power supply 
are functioning properly.

Power supply and fans appear 
operational, but none of the I/O 
LEDs are on.

The improperly 
connected port 
adapter has 
indefinitely 
paused the 
system. 

Reseat the port adapter, make sure the port 
adapter lever is in the locked position, and then 
restart the system.

The prior configuration—native 
Gigabit Ethernet—LEDs remain 
on after configuring the ports to 
change the configuration from 
one media type to the other.

The media-type 
command was 
not used when 
changing the 
configuration of 
these ports.
