Re: 3550 switch not booting

Hello Sagar,

From the output we can see :

=================

POST: CPU Interface Tests : Begin
Timeout while verifying the CPU Interface channel 0 on switch core 0
POST: CPU Interface Tests : End, Status Failed

=================

POST failure usually means there is physical damage. You need to replace your switch (do a RMA).

Thanks.

Karim
