Posted: 07 Aug 2024, 09:05
Applicable Versions:
TOS 5.0.xxx, TOS 5.1.xxx ，TOS6
Applicable Models:
TNAS models (except F2-210, F4-210)
Fault Symptoms:
When the TNAS crashes, causing the web page to be inaccessible and the PC unable to find the device, the system report on the TOS web page lacks related logs after rebooting, making it difficult to analyze the cause of the exception.
Fault Reason:
When the TNAS device crashes and reboots, some system-related logs are cleared. To address this, other log collection methods are required to analyze the exception.
Steps for TOS5 Operation:
Step 1: Use tools like Putty to log in to the NAS command line terminal.
