Hi all experts,

Just want to find out if there is any simple way to find out if a router or a switch is having hardware problem (eg. fastethernet ports or Serial ports).

The story is that I have about 50 equipments (switches and routers) in the stock. I am assigned a job to verify if the equipments are usable. So, is there any simple way either from the LED, IOS or bootstrap that I can find out wether all the ports are in good condition?

Thanks,
MH Hong

connect a rollover cable at the back of the cisco equipments boot the device and watch it come up if it successfully boots then logon or if you do not have the password reboot the equipment and during boot hit the CTRL+Break key and change the configuration register
http://www.cisco.com/en/US/products/hw/routers/ps133/products_tech_note09186a008022493f.shtml this will help you with the configuration register.

On the other hand if you have the password logon to the equipment and use the show tech or show interfaces
A sure test will be to connect equipment onto the switch and run show interfaces as there may be a physical problem on the ports.
for the routers you have fewer ports so connect the switches to the router and run a show cdp neighbor detail this will show you the switches.
Just in case you do not know all these commands have to be run from the priviledged mode accessed by enable command from the prompt.
Good luck
