3. 下载和服务器操作系统对应的Firmware安装包。

sudo dpkg -i --force-overwrite fw_OAM1.5G_PCIE1.6G-1.5.8-b023cf.deb

sudo rpm --force -ivh --nodeps fw_OAM1.5G_PCIE1.6G-1.5.8-b023cf.rpm

如果更新fw之后，icn link没成功启动，可以通过ppu-smi -r恢复。

Firmware Backup

firmware版本在v1.4.0以上版本才支持此功能。

#1.升级前firmware版本不低于v1.4.0
#2.升级firmware
dpkg -i --force-overwrite fw_OAM1.5G_PCIE1.6G-1.5.8-b023cf.deb
#3.在步骤2执行一半时,在另外一个窗口执行reboot进行断电操作
reboot
#4.服务器reboot成功后，查看fw版本升级成功，并检查环境
ppudbg --device 0
ppudbg --device 1

版本确认

运行ppu-smi工具，会打印出对应的PPU信息，其中VBIOS Version是对应的PPU Firmware版本信息，如下所示：

# 运行ppu-smi工具
$ ppu-smi -q | grep "VBIOS Version"
    VBIOS Version                           : 1.5.8-b023cf
