Dear all, My brand new N200 seems to be dead. All front panel lights are off. Network lights are off either in N200 or in the laptop (Lenovo T530 with 1 Gbit eth iface). Power cycling with S2 pressed doesn't help. The only thing that is functional is the fan. I use the provided power supply and the ethernet cable connected straight to the laptop. Do you have maybe any clues on what is wrong? Your help will be appreciated. -- Leszek

Hello Leszek Erbel: There are some things you can do to diagnose your new N200. The User Manual page for the N200/N210 is at the link below. http://files.ettus.com/manual/page_usrp2.html Information about the LEDs can be found in the User Manual at the link below. http://files.ettus.com/manual/page_usrp2.html#usrp2_hw_leds You can try booting your N210 into Safe Mode. More information about Safe Mode can be found at the link below. http://files.ettus.com/manual/page_usrp2.html#usrp2_loadflash_brick Listed below are some specific things that you can check to verify whether or not your N200/N210 hardware is working correctly. If the answer to any of the questions listed below is "no", then there is probably a hardware problem. * Does the fan spin? * Do any of the LEDs on the front panel light up? ( http://files.ettus.com/manual/page_usrp2.html#usrp2_hw_leds) * Are the lights on the Ethernet port flashing, when the N210 is connected to the host computer? Are any lights flashing on the host computer's Ethernet port? Note that the N200/N210 must be connected to a 1 Gigabit Ethernet port. A 100 Mbps Ethernet port will not work. * Check the voltages on these connectors on the motherboard: J105 (should be 2.5V); J104 (should be 3.3V); J107 (should be 1.2V). Do you see the correct voltages on those connectors? * Does the LED at D203 on the motherboard light up? If you're holding the N210 such that the front panel is facing you, then D203 is located near the left connector for the daughterboard. Please let me know the results of these tests, and we'll go from there. --Neel Pandeya On 31 May 2015 at 23:23, Leszek Erbel via USRP-users < usrp-users@lists.ettus.com> wrote: > Dear all, > > My brand new N200 seems to be dead.

Hello Neel, Thank you very much for your comprehensive statement. My USRP was bought through NI. So a few days ago I contacted them. Based on symptoms they diagnosed a failure. I also checked voltages and 1.2V was missing. My N200 was sent to repair from which I hope it will return soon. -- Kind regards Leszek 2015-06-12 20:31 GMT+02:00 Neel Pandeya <neel.pandeya@ettus.com>: > Hello Leszek Erbel: > > There are some things you can do to diagnose your new N200. > > The User Manual page for the N200/N210 is at the link below. > http://files.ettus.com/manual/page_usrp2.html > > Information about the LEDs can be found in the User Manual at the link > below. > http://files.ettus.com/manual/page_usrp2.html#usrp2_hw_leds > > You can try booting your N210 into Safe Mode.
