Other configuration features
This section includes information about the following optional feature codes that
you can specify to customize or to receive your DS8000 storage unit:
v Extended power line disturbance (EPLD) option
v
Remote System z power control option
v Earthquake Resistance Kit option
v
BSMI certificate (Taiwan)
v Shipping weight reduction option
Extended power line disturbance
The extended power line disturbance (EPLD) feature allows your storage unit to be
protected for 50 seconds, rather than only milliseconds, from a power line
disturbance. This feature is optional for your storage unit configuration.
Without the EPLD feature, a standard DS8000 storage unit offers you about 30
milliseconds of protection from power line disturbances. Adding this feature
increases your protection to 50 seconds.
You order the EPLD feature for your storage unit. All models must contain battery
assemblies. “Configuration rules for power features” on page 116 provides more
information about the configuration rules for battery assemblies.
Feature code for extended power line disturbance
