49 TopicsGS308E funktioniert nach Stromausfall nicht mehr.
Guten Tag, mein Switch GS308E funktioniert nach einem Stromausfall nicht mehr. Es blinken lediglich die Power und die ganz rechte LED. Der Switch wird auch von meiner Fritz Box nicht mehr erkannt. Ein längerer Reset von mehr als 30 Sek. brachte ebenfalls keinen Erfolg. Der Switch war jetzt mehr als 24 Std stromlos, doch auch Heute nach erneutem Anschließen keine Änderung. Der Switch ist gerade 10 Monate alt und hat bis Gestern, vor dem Stromausfall einwandfrei funktioniert. Ein Zugreifen auf die Oberfläche ist nicht möglich. Könnte es sein, das sich die Firmware verabschiedet hat ? Sollte jemand eine Idee haben ob es noch Möglichkeiten gibt den Switch wieder zum Leben zu erwecken, ich würde mich freuen. Gut gemeinte Ratschläge werden dankend angenommen, allerdings bin ich Laie und kein IT-Fachmann. Vielen Dank im Voraus Jo27Solved3KViews0likes6CommentsM4300-52G-PoE Stuck in U-Boot - ERROR: can't get kernel image!
Hi Everyone, This is my first post to the Community. I am posting this procedure for those poor souls out there, which like me have experienced this issue (there are several similar posting on this forum with no solution). It took me several valuable hours to get this. This is the procedure to get your Netgear Managed Switch up and running to be able to do detailed diagnostics (in my case it turned out the flash partitions for the 2 image packages were toasted) 1. Download a Firmware Image file for the M4300 from the Netgear Support website 2. Extract the Firmware Image file from the downloaded Zip file to your PC/Laptop 3. Ensure you have a TFTP Server installed on your PC/Laptop 4. Connect to the M4300 via a Console cable 5. Power on the M4300 6. let all the Errors display and wait for the U-Boot "m4300r2>" prompt to appear 7. enter "printenv" and check that the following Environment variables have the following values : - ipaddr=192.168.0.10 - serverip=192.168.0.100 8. if values don't match above, enter the following commands - "setenv ipaddr 192.168.0.10" - "setenv netmask 255.255.255.0" - "setenv gatewayip 192.168.0.1" - "setenv serverip 192.168.0.100" 9. Set your PC/Laptop Ethernet interface IP to 192.168.0.100 10. Connect PC/Laptop Ethernet interface to the OOB Ethernet port on the front of the M4300 11. Start your TFTP Server on your PC/Laptop and set the root directory to the location of the extracted Firmware Image file 12. Enter the command "run bootargs_set" 13. Enter the command "tftpboot 0x62000000 m4300v12.0.13.8.stk" [Note: I used ver 12.0.13.8, use whatever filename is in the Firmware package] 14. Wait for the Firmware to upload to the M4300 15. Do NOT disconnect the Ethernet connection 16. Enter the command "bootm 0x62000074#ranger2" 17. The M4300 will begin to load the Application file and error again -- don't panick 18. The M4300 will again automatically load the Firmware Image file from the TFTP Server 19. Then Finally, at last, the M4300 will boot to a fully operational condition 20. Optional: Enter the commands "#delete 1 image1" and/or "#delete 1 image2" 21. Optional: Enter the commands "copy tftp://192.168.0.100/m4300v12.0.13.8.stk image1" and/or "copy tftp://192.168.0.100/m4300v12.0.13.8.stk image2" 22. Optional: Enter the commands "boot system 1 image1" and/or "boot system 1 image2" In my case the last 3 commands all failed as the Flash was obviously damaged :( PS: Why Netgear does not publish recovery instructions for the M4300 series is baffling to me, given there are many request on this forum and others requesting it . . . . anyway thought I would share . . . . hope it works out for you2.5KViews3likes1CommentFirewall nur für das LAN

Hallo! Bitte um Hilfe! Soeben habe ich via Amazon den Switch GS308Ev4 erhalten. Wenn ich mich mit der Seriennummer registrieren möchte, erhalte ich die Info: Das Kaufland des Produkts ist ungültig.

I can't connect to a ProSafe switch at all because the Netgear Discovery Tool will not allow me to select a connection to scan. On top of that, the default IP of the switch is not 192.168.0.329 (even after factory reset) and the ProSAFE Plus Utility doesn't run no matter how I try to engage it. Windows 11, for what it's worth (I saw the .NET 4.6 install req on the PPU, but that won't install because it says I have a newer version already).Can't login to M4300 since 12.0.19.15 firmware update
Hello, I just updated two switches M4300-28-POE+ to 12.0.19.15. I go to the IP address of the switch It has the AV UI login and the Main UI Login - I can log into the AV UI login but NOT the Main UI login which is the one I need. It goes to this site can't be reached. I reload no luck. I rebooted the switches - no luck. I tried another browser - no luck. I tried incognito mode, no luck. There is no firewall or antivirus blocking it. It worked fine until the firmware update. Short of resetting the switch to factory defaults which probably won't fix it, any suggestions other than applying an older firmware?499Views1like3CommentsCloning or backing up and restoring a stack to another stack?
Hello, I'm setting up 4 floors of M4300 - 2 x 52 and 1 x 28. What is the easiest way to do it? I have one stack ready to go but the other three won't be arriving for a few days. I plan on putting them all on the same firmware before I do anything. Should I just reset all the new switches to factory defaults and then clone switch 1 to 1 for the next floor and 2 to 2 and 3 to 3 or should I do the entire stack at a time? Any suggestions would be appreciatated.Solved400Views0likes1CommentAV VLAN uplink to public manage switch
Hi All: At our educational facility we are redesigning an existing 2 x room AV system with "cross-room" Audio Visual broadcast connectivity using Crestron Digital Media architechture Each room has a dedicated Crestron DMPS-4K-350-C + DMPS-4K-250-C units with with TV displays, Microphones and Camera's. We have a new Audio Visual private VLAN link between 2 x rooms using core Netgear AV Line switches being programmed for the Crestron Graphic User Interface control in each space. Netgear M4250-9G1F-PoE+ network switch (smaller room 1) + Netgear M4250-26G4F-PoE+ (GSM4230P (larger room 2) My question is for how we can securely manage the AV endpoints inside the private AV VLAN? Crestron virtual X-panel touch screen control is needed + two DMPS hardware units, Biamp audio processors; we need IP control into this new private AV-VLAN from our existing public managed Switch local subnet. I would like to create an ethernet patch uplink from the core Netgear M4250-26G4F-POE (same AV system rack as our Crestron Managed switch) into our local managed public subnet switch which is a Crestron CEN-SW-POE16 Any thoughts on the best way to configure this would be appreciated.
