Maintaining the storage system
Ongoing proper maintenance of the storage system maintains the reliability of the storage system and its constant availability to all hosts connected to it.
For more complex maintenance activities, contact customer support.
Storing the storage system
If the storage system does not receive power for more than six months, the battery can become discharged and possibly damaged. To avoid this situation, charge the battery for more than three hours at least once every six months.
Powering off the storage system
Press the main switch on the controller chassis for approximately three seconds until the POWER LED on the front of the chassis changes from solid green to a blinking status.
Release the main switch and the POWER LED returns to solid green after blinking for approximately three seconds.
The power-off process begins. The process takes approximately 18 minutes or longer depending on the amount of data that needs to be written. The POWER LED is solid green during the powering off process. The POWER LED changes from green to amber when the process is completed.Verify the POWER LED on the front of the storage system changes from green to amber.
To stop the power supply, remove the power cables from the power supply units on the controller chassis and drive box.
If the storage system is connected to a PDU, you can stop the power supply by turning off the PDU breaker.NoteIf the storage system does not receive power for more than six months, the battery can become discharged and possibly damaged. To avoid this situation, charge the battery for more than three hours at least once every six months.
Battery unit
The battery life time is affected by the battery temperature. The battery temperature changes depending on the intake temperature and height of the storage system, the configuration, operation of the controller boards and drives, charge-discharge count and others. The battery lifetime will be three to five years.
Use the storage system in a place where the ambient temperature is 86°F (30°C) or less on average.
Periodic parts replacement is required. If you have a maintenance service contract, parts are replaced periodically according to the terms of the contract.
The battery lifetime (intake temperature is 30 degrees C or less.) in the standard environment is as shown below.
Removing cables
Observe the following instructions when removing cables form the storage system.
To remove an optical cable, push the top of the connector of the optical cable (1) to release the latch and remove the SAS cable (2).
To remove a LAN cable, push the top of the LAN cable connector (1) to release the latch and remove the LAN cable (2).
