BootRom菜单升级过程中可能会遇到此提示操作不支持

BootRom菜单升级过程中可能会遇到此提示操作不支持该怎么办？

在V7交换机升级的过程中不知道大家是否遇到此种情况，即提示情况如下：

   EXTENDED BOOT MENU

1. Download image to flash

2. Select image to boot

3. Display all files in flash

4. Delete file from flash

5. Restore to factory default configuration

6. Enter BootRom upgrade menu

7. Skip current system configuration

8. Set switch startup mode

0. Reboot

Ctrl+Z: Access EXTENDED ASSISTANT MENU

Ctrl+F: Format file system

Ctrl+P: Change authentication for console login

Ctrl+R: Download image to SDRAM and run

Ctrl+Y: Change Work Mode

Ctrl+C: Display Copyright

Enter your choice(0-8): 1

1. Set TFTP protocol parameters

2. Set FTP protocol parameters

3. Set XMODEM protocol parameters

This operation is not supported in PEX mode

大家看到此处可能有懵了，其实这是支持irf3堆叠设备新添加了Ctrl+Y: Change Work Mode，更改工作模式选项，出现上面情况可能是客户误操作了按了ctrl+Y或是客户的网络中配置了irf3，其中此设备是做为PEX设备导致。解决的方式其实特别简单就在按一下ctrl+Y把模式更改回来就ok了。
