Power Save: Disable the Power Save Feature
Disabling the Power Save Feature
Cisco strongly recommends that you leave the Power Save feature enabled.
However, if you have some subscribers who request that the Power Save feature be
disabled, we can provide a mechanism for you to disable the feature. Contact Cisco
Services for assistance.
Important: Sites using the Pioneer Passport or other resident applications should
contact their application vendor for information on how their application allows for
hard disk spin down and power saving on the DVR.
