FTD 4225 cannot detect disk0, it stuck at rommon mode

I am currently doing initialization for FTD, but it seems cannot detect disk0, and it keep rebooting and eventually stuck at rommon mode.

any idea how to fix it?

- Can you use BREAK or ESC to interrupt the boot process

This is most likely a hardware failure.

Since it is a new device, you should contact TAC for confirmation and they will ship a replacement device.

thanks Marvin,

I have two appliances, they have the same issue, is it such a coincidence?

It could have been a bad production line issue that day - especially if their serial numbers are close to each other. In any case, a TAC engineer can confirm it in about 15 minutes.
