![]() If you wish to flash your MS210/MS225, you will need to remove or socket the SOIC8 SPI flash. The firmware layout follows the standard Meraki practice of having A/B firmware images: bootkernel1, bootkernel2, part.safe, part.old. The stock Meraki boot process uses u-boot on SPI to load a “bootkernel” (also from SPI), which then initializes NAND and using kexec boots the main firmware. ![]() Early in the boot process switch_brain checks the switch model, and if it identifies as the MS210 series the SFP port speed is limited to 1000M. The answer is market segmentation Meraki decided to artificially limit the speed of the MS210 SFP ports to 1G, even though the MS210 hardware is capable of 10G via SFP+. Keen readers may be wondering why the MS210 series has only SFP ports while the MS225 has SFP+ ports, given they are identical hardware and run the same switch-arm firmware. ![]() ![]() The MS250 is essentially the MS225 with hot-swap power supplies (similar to the MS220/MS320). The Meraki codename for the MS210 and MS225 series is “brumby” and all brumby switches run the same firmware release ( switch-arm). MS225-48LP switch internals with PoE midplane removed
