Is there any chance someone might help me find the X86_64-3.10.4206-installer.bin for the sn2700 switch? Been looking all over and the switch is well out of warranty.

我有一台SN2700,现在开机系统故障灯报错(常亮红灯),然后在系统里面有报错提示,换了电源模块还是出现同样的错误,哪位能帮帮我吗?

I have a SN2700, and now the system fault light is reporting an error (red light is constantly on). There is also an error prompt in the system. I replaced the power module, but the same error still occurs. Can anyone help me? Thank you

This was a bug in an earlier Oryx version, once you upgrade the warning goes away. Which is why the person above ^ asked the verison. Make sure you running latest.

The SN2700 can currently be purchased for 6,500 RMB on Chinese second-hand e-commerce platforms
Additionally, I would like to inquire, is it possible to adjust certain settings on the SN2700 40G to achieve a rate of 100G?

Is it possible to upgrade to version 3.10.460? Thank you for your guidance!

我想问一下,我有一台 SN2700,想安装最新的系统。我可以进入 BIOS,但是无论我怎么插入 U 盘,它都无法进入 U 盘安装模式。相反,它会自动进入救援模式。这是什么原因造成的?

PS:即使更换了U盘,问题仍然存在。

I have to ask, I have this sn2700 and I want to install the latest system. I can enter the BIOS, but no matter how I plug in the USB drive, it doesn't enter the USB drive installation mode. Instead, it automatically enters rescue mode. What could be the reason for this?
PS: Even after changing the USB drive, the problem persists.

The system will prompt —— discover: Rescue mode detected. Installer disabled.

I am not sure if the 200G is hardware or software locked. I know on the SN2100B versions (40/56Gbit) we were able to get them to run at 100G with little effort. I can't remember if we popped a cable in and it worked or if we re-flashed. On the other hand, the 56Gbit capability doe require a special QSFP cable and Mellanox cards on the host side that can handle it (plus drivers). I have a couple SN3700Cs out back. If I can procure a 200Gbit cable at some point, I will try it out.
What is the procedure to do this? also have you tried flashing the firmware with mst?

has anyone heard of a single case of a SN2100 failing? picked up a 2018-01 revision B3 setpci shows 2, cpu is "vulnerable" but not sure if pcb or any kind of fixed was applied.

For those who like me are stuck in the the update bios loop i managed to solve it by booting in onie rescue, mounting the partition where onyx is installed and rename /opt/tms/bin/bios_update.sh to .bak . This allowed the boot to skip updating bios and boot normaly.

Ok nevermind, i went from 3.8.2008 straight to 3.9.3124, then to 3.10.2102 and finally to 3.10.4408 without problems.
Could you please share your onyx-X86_64-3.10.2202.img or 3.10.2102 file? Thank you very much.

I wanted to thank the thread curator and author NablaSquaredG and nasbdh9 for the information, documentation, sw links and guidance, along with other contributors. Without your information, It would have been more difficult to resurrect my telco auction'ed SN2410 switch. My switch sustained some physical damage to the front somewhere in its life, also the mgmt board supercapacitor seems to be leaking. If anyone else needs a replacement, take a look at the attached pictures for the part number. I think the SC is responsible for keeping the mSata alive after an unintentional power loss long enough to write out its buffer.

No, this supercapacitor is for real-time clock (like CMOS battery in a normal PC). It works fine without it.
