On the ES NAS, what do the four indicators on the bottom-left corner of the rear of the controllers show?


最終更新日: 2018-03-02

These four indicators display major system information, and help users to determine the current status of the ES NAS.

First from left: System Status Indicator. Displays three different statuses: Off (the system is turned off), blinking (the system is starting up), and green (the system is working normally).

Second from left: Fan Status Indicator. Displays 2 different statuses: Blinking (the fan is not working normally), and green (the fan is working normally).

Third from left: Backup Battery Unit (BBU) Status Indicator. Displays four different statuses: Red (the BBU is not working normally), orange (BBU is charging), blinking (the connection to the mains power is lost, the BBU is supplying power for the Copy-to-Flash operation), green (the BBU is working normally).

Fourth from left: System High Availability (HA) Status Indicator. Displays 3 different statuses: Orange (takeover mode), blinking (takeover or giveback in progress), green (the system is working normally).

These four indicators display major system information.
