The Server Technology® PRO2 Switched CDU provides control of outlet power and local LED input current

monitoring, allowing IT personnel to determine safe levels of loading on a per-phase basis while installing

equipment into the rack/cabinet. The integral PIPS® technology provides billing-grade accurate measurement

of current, voltage, active power, apparent power, power factor, crest factor, and accumulated energy at the input.

These power data points, along with temperature and humidity measurements (provided via optional probes),

are accessible through the built-in Web and CLI interfaces as well as through SNMP. The PRO2 Switched "Master"

CDU can be connected to as many as three PRO2 Switched "Link" CDUs to extend the network access to the

redundant or secondary power feed without the risks of a daisy chain linking configuration.

Sentry Cabinet PDU Features

Network Monitoring
The PRO2 hot-swappable network card provides for HTTP(S), SSH, Telnet,SNMP, (S)FTP, SMTP, Syslog, LDAP(S), RS-232 serial, and more.

Branch Current Monitoring
PRO2 monitors current at each breaker branch and provides SNMP-based alerts and emails on high usage that risks a tripped circuit.

Star Multi-Linking
PRO2 provides the ability to link up to four power circuits using one IP
address. Primary link provides backup power to network card.

Branch Circuit Protection
PRO2 meets the UL and IEC 60950-1 requirement for branch circuit protection
through use of UL489 rated magnetic-hydraulic circuit breakers.

Hot-Swap Network Card
Network access is ensured when power is lost to the Master unit with
backup power provided by the primary link unit.

ST Eye Bluetooth Ready
The best CDU LCD is the one in your hand. Attach the ST Eye™ Bluetooth
module to PRO2 for access to power data and system settings.

Temperature/Humidity Monitoring
PRO2 Master and Link units each support two external 10' (3m) T/H
probes. Receive SNMP-based alerts and email notifications.

High Retention Locking Outlets
PRO2 receptacles have high retention and are compatible with Server Technology's LockedIn™ power cords (sold separately).

Outlet Control
On PRO2 Switched CDUs, cycle power to individual outlets or groups of
