Required ESM Replacement

Based on the expected life of the ESM in supported hosts, and to maintain optimal card performance, plan to replace the ESM according to the table below.

Host System	Expected ESM Life
Exadata V2	3 years
Exadata X2-2, X2-8	4 years
All other supported servers	3 years

To help you monitor the age of the ESM, Sun provides two options for monitoring the ESM, see Monitoring ESP Lifespan. To service the ESM (F371-4650), see Servicing the ESM.

If the charge capacity in the ESM falls below the minimum threshold, then Oracle will replace the failed ESM module at no extra charge, if the system is covered either by the Oracle Premier Support for Systems or occurs during the warranty period.

Caution - If the ESM is not replaced at the recommended service interval, the level of stored energy will continue to degrade over time. Any data stored on the card is at risk of being lost if there is not enough stored energy to complete a write operation during a power failure. To avoid this risk, replace the ESM at the recommended service interval.

Note - The long-term durability of the ESM is affected by excessive heat. Refer to your server product notes to understand any slot or thermal restrictions that apply to your server.
