Replacing Batteries

The batteries of the ETERNUS DX are expendable components that need to be replaced periodically.
Batteries can be replaced during regular maintenance free of charge. For customers without a maintenance con-
tract, replacement requests (payment required) must be made.

Do
• The replacement cycle for a battery is shortened if the battery is used at high tempera-
tures or the battery charges and discharges frequently.
If the time to replace the battery is near, contact your maintenance engineer to re-
•
place the battery. If the battery is still used even after the replacement time has
passed, the performance of the ETERNUS DX degrades because the operational state
of the cache is changed to Write Through mode.
