Hi @QDoan ,

Please try to access SZ100 using console cable and check if you can login or noticing any abnormal errors in the Console screen.

Hi @QDoan 

You can access the SZ via console port, please try the below steps:
Connect the console cable from your PC to SZ's console port.
-Open PUTTY and Configure the serial connection settings as follows: 
· Serial line to connect to: Type the COM port name to which you are connected 
· Bits per second: 115200 
· Data bits: 8 
· Parity: None 
· Stop bits: 1 
· Flow control: None

If you are able to login from the console, you can try upgrading the SZ from the CLI. Below article explains the steps:

Hi @QDoan 

I see DRDY ERR  errors in the boot process. Generally, these errors "{ DRDY ERR }" will generate when there is a hardware failure in the SZ.
You probably need to go for an RMA.
