PowerZook is a power sensor that can be installed without system downtime to provide rack input power readings via SNMP. PowerZook clips around the outside of rack input power cables to monitor the power draw of the rack equipment for loads of up to 32A. PowerZook provides a smart alternative to smart PDU's where system downtime and/or higher costs are not viable options.
Monitor up to 10 of these for free with the Mutiny Community Edition monitoring system.
