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
contract, replacement requests (payment required) must be made.
■
Replacement Cycle for a Battery
If a battery is used at an average temperature of 25
°C, the battery can be used for the entire maintenance
support period (five years). The replacement cycle for a battery varies according to the customer's environment
and usage.
• The replacement cycle for a battery is shortened if the battery is used at high
temperatures or the battery charges and discharges frequently.
■
Checking the Time to Replace the Battery
• If the time to replace the battery is near, contact your maintenance engineer to
replace the battery. If the end of the battery's life is detected by the ETERNUS DX
due to continued use even after exceeding the replacement period, the
performance of the ETERNUS DX degrades because the operational state of the
cache is changed to the Write Through mode to protect the data.
The time to replace the battery can be checked by using the following options.
If the time to replace the battery is near, contact your maintenance engineer.
• Check the time to replace the battery by using ETERNUS Web GUI or ETERNUS CLI.
• If the time to replace the battery is near, a notification is sent via an e-mail or an SNMP trap message.
- A notification is sent six months before the expiration date.
- A notification is sent everyday for a week before the expiration date.
