Power-on self test (POST) failures are hardware-related.

You need to open a TAC case. Cisco TAC will issue a Return Material Authorization (RMA) and send you a new switch.

If you don't have Cisco Smartnet contract support then you will need to replace the switch.

Hello Marvin, You mean the following error "POST: PortASIC Port Loopback Tests : Begin
POST: Failed PortPhyLoopback Packet Test asic_index 0 port_hardware_index 9
POST: Failed PortPhyLoopback Packet Test asic_index 0 port_hardware_index 15
POST: PortASIC Port Loopback Port Tests : End, Status Failed
Error: ASIC/PHY POST failed. Cannot continue" implies only RMA change?

Hello,

what happens after ? Does the switch boot up ? Check if you hit the bug below:
