46 TopicsM4300-52G-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 you2.4KViews3likes1CommentInquiry: 24×1 Gbps Copper + 2x10G Copper & 4×10 G SFP+ Uplink - Layer‑3 Switch (non‑PoE)
Hello, I am looking for a Layer‑3 switch from NETGEAR with the following specifications: 24 ports of 1 Gbps copper RJ‑45 (non‑PoE) 2 ports of 10 Gbps copper & 4 ports of 10 Gbps SFP+ uplinks Full Layer‑3 routing features (static routing, inter‑VLAN routing, etc.) I previously used the GSM4328S, but I understand that it has been declared End‑of‑Life (EoL). Could you please advise if NETGEAR currently offers a model that matches or closely matches the above requirements? If there is none, I’d appreciate suggestions for the closest alternative.84Views1like4CommentsGS316EP POE is dead
Hello everyone, I got a GS316EP switch with PoE, everything worked fine with 3 APs WAX610 but now there is no PoE anymore. GS316EP is on the newest firmware, I resetted it etc. APs are working fine if they are powered externally but not with PoE. I also ordered a PoE Tester and there is also no power over the cable. I also tested directly at the switch. PoE Settings for the port are standard: IEEE902 802.3at 30 W But the status (same for every port) shows deactivated, 0 V, 0 mA, Status: No Errors, 0 W but Temp 275 C°. Can someone help me out?53Views1like1Comment
