1 If you manage a datacenter, we have a solution for you. How do I... Distribute power to all the equipment in the cabinet? Distribute and load balance 3-phase power? Monitor True RMS input current? Reboot remote servers and network devices? Know when the cabinet temperature is too high? Provide adequate power distribution for blade servers? Sentry : Cabinet Power Distribution Unit Product Family : Metered CDU Cabinet Power Distribution with Local Input Current Monitoring and Branch Circuit Protection. Smart CDU Power Distribution with the expanded functionality of SNMP-based Input Current Monitoring and Temperature and Humidity monitoring. Switched CDU Flagship CDU with remote monitoring and management, including reboot commands to connected servers and network equipment.

2 Sentry : CDU Product Family Sentry : CDU Anatomy The complexity of IT equipment in today s data centers and remote branch office locations requires new solutions for building a solid infrastructure. It must support 24/7 operations and reduce the instance of locked-up or failing equipment leading to network downtime; Five nine s availability % uptime demands it. Blade servers and high density computing power requirements continue to increase, creating heat proliferation and more challenges for managing the IT environment. To maintain their competitive advantage, data center managers need SNMP-based solutions that monitor, track and manage servers and IT equipment and the equipment cabinet infrastructure that houses them. The photo below illustrates where each of the CDU s key features are located: Serial access for RS-232 and local communications. Integrated Power Metering Displays per branch circuit or phase. Integrated support for Temperature and Humidity probes. IP-enabled for Secure Web, SSH & SNMP management UL Branch Circuit protection with UL listed fuses. The Sentry CDU Family delivers these solutions with three distinct product lines: Metered CDU Cabinet Power Distribution with Local Input Current Monitoring and Branch Circuit Protection. Smart CDU Power Distribution with the expanded functionality of SNMP-based Input Current Monitoring and Temperature/Humidity monitoring. Switched CDU Completes the solution by adding Full Remote Monitoring & Management, including reboot commands to connected servers and network equipment. CDU Product Family Solutions for the Data Center Equipment Cabinet 120V or 208V output for up to 84 output receptacles. Center rail notch for flush mounting in cabinet. Single-phase or three-phase power input for up to 20kW.

4 Metered CDU : Key Features The Sentry Metered CDU products provide reliable power distribution for all the devices in your equipment cabinet, from 5,000 to 20,000 Watts per cabinet. Single-phase V or power distribution with options -or- 3-Phase ; 20A or 30A power distribution options. Local input current monitoring allows the installation engineer to verify the aggregate load on the circuit or phase. Branch Circuit Protection The Sentry CDU Family meets the new UL requirement for branch circuit protection. Attention! The Sentry CDU products meet the UL criteria by providing overcurrent protection with UL listed Bussman SC fuses for each branch circuit. Input Current Monitoring The CDU s exclusive True RMS current monitoring is critical to preventing overloads in high-density computing environments. LED digital displays on the CDU enclosure report the input current of each phase or branch circuit. Button Mounting All CDUs are also compatible with button mounting. Several cabinet manufacturers are now using this method for installing power distribution units in the cabinet. Equipment Cabinet Power Demands on the Rise From , data center equipment cabinet power requirements increased by over 1000%. That equates to an average annual power increase of over 3000 Watts annually. Is your power distribution system up to the challenge?

6 Smart CDU : Key Features The Smart CDU products provide reliable power distribution combined with remote power and environmental monitoring. Use the network interface to view power, temperature and humidity levels via Web browser, or receive SNMP-based alarms when conditions exceed defined thresholds. Trends Impacting Data Center Power Distribution > More high-density, multiple units filling racks and cabinets. > More systems with higher and increasing power density. > More use of higher rated supplies to reduce cabling costs. > More use of intelligent power and metering. > More 3-Phase applications and increased use of metering to insure load balanced phases in such systems. > More systems with higher nominal input voltage ratings (208V vs. traditional 120V). > More individual power distribution units being provided with an increasing number of outlets. > More global power distribution equipment being developed at 20A and 30A. > More use of IEC outlets, especially for a global product with 208V nominal supply ratings. (Source: IEEE) CS-12HD2 (2U;10in Depth) Branch Circuit Protection IP Blade Server Horizontal CDUs Input Current Monitoring Button Mounting Input Current Monitoring The Smart CDU and Switched CDU also provide IP-access to Input Current Monitoring. Receive SNMP-based alerts when power draws exceed defined thresholds. Temperature & Humidity Monitoring The Smart CDU and Switched CDU support two external probes. Each of these probes measure both temperature and humidity. Receive SNMP-based alert notifications when conditions exceed defined thresholds. Enterprise View PDU Management Enterprise View uses auto discovery to locate all CDUs from one location and provides a graphical interface for each unit. Monitor temperature and humidity levels at each site; receive notification of critical conditions when input current or environmental conditions are outside defined thresholds. Center Rail Notch An exclusive design feature allows the CDU to be mounted flush inside the cabinet, over the center rail commonly found in HP, Dell and other popular cabinets.

The Switched CDU s combine remote configuration and management with power distribution and power and environmental monitoring. Reboot a single or dual-power server with one command. Receive SNMP alerts when power or environmental conditions exceed thresholds. Assign users specific access rights to designated outlets or groups. Only the Switched CDU products provide the flexibility needed for all data centers and remote sites, including power requirements for high-amp, high voltage; UL branch circuit protection; SSL& SSH security; and SNMP-based input current monitoring. Switched CDU : Expansion Module The Expansion Module CDU CX is our exclusive method for linking outlets on different power circuits together. A CX links to any Switched CDU, increasing the number of managed outlets on a single IP address. Control individual outlets on either the Switched CDU or CX, or control grouped outlets between the Switched CDU and CX with one command. IP Input Current Monitoring Branch Circuit Protection Temperature and Humidity Monitoring Button Mounting Enterprise View PDU Management Remote Management Point. Click. Reboot. Reboot a locked-up server from a remote location. The Switched CDU s firmware interface provides complete configuration and control of the unit from a remote location via Web, SNMP or serial access. Create user accounts and assign access rights. Simultaneous user access makes the Switched CDU an ideal solution for co-lo sites where both host and remote user need access to reboot servers. Create groups of associated outlets and reboot a dual-power server with one point and click. Security and communications features include SSL, SSH, MD5, TACACS, and LDAP. Power-up Sequencing of outlets and High-amp in-rush protection ensures safe boot-up of all your equipment. Each CX links to a Switched CDU, which contains both network and serial interfaces. When linked to a Switched CDU, the CX s outlets are auto-discovered by the Switched CDU s firmware, and all available outlets CW CX are viewable and CW-2H1 (1U; 4.75 Depth) CW-8H1 (1U; 10in Depth) controllable through the firmware.
