After updated firmware to 4.5.2, system reported fan speed error and NAS status error in storage snapshot management

Last modified date: 2022-10-18

Applied models:

TS-EC880U-RP and other rack mount models

Applied Firmware:

4.5.2.1566 or previous version (build before 20210202)

This error symbol indicates “NAS host” issue but not related to storage pool or RAID. Because system (4.5.x) tried to fetch fan speed of PSU but failed (PSU doesn’t support fan speed reporting), so that system would show fan speed “null”(--) and in red. This display about fan speed empty has been changed in the latest firmware version, with it in black to mean it’s not available for detect, and the error symbol on storage snapshot management UI will be eliminated too.
