EonStor A16E-G2130-4 Installation and Hardware Reference Manual  
 
Audible Alarm - If any errors occur during the initialization process, the onboard 
alarm will sound in a hastily repeated manner.   
Drive tray LEDs should normally start flashing right after power-on, indicating the RAID 
control unit is attempting to access the hard drives. 
 
 NOTE: 
The subsystem has been designed to run continuously. Even if a component failure 
occurs the fault can be corrected online. 
 
4.4  Power Off Procedure  
To power down the EonStor subsystem, please follow these steps: 
 
 NOTE: 
When powering down the EonStor subsystem, please ensure that no time-consuming 
processes, like a “Logical Drive Parity Regeneration” or a “Media Scan,” are taking 
place. 
 
 Step 1. 
Stop I/O access to the system.  
Stop all I/O accesses to the A16E subsystem. Please refer to the related 
documentation of your applications. 
 Step 2. 
Flush the cache. 
Locate the Cache_Dirty LED on the back of controller module to check 
if there is data cached in the memory. Use the Shutdown Controller 
function to flush all cached data. This prepares the RAID subsystem to 
be safely powered down. 
 Step 3. 
Turn off the power. 
Turn off the power. Once the RAID subsystem has been powered down, 
other devices connected to the subsystem can be powered down.
