Integration with HP SIM The HP PDR Management Module can be integrated with HP SIM for a comprehensive data center management solution. HP SIM allows facility managers to discover (detect) newly installed HP PDR Management Modules, launch the web interface of a management module from within HP SIM, and receive SNMP traps from management modules. The following basic procedure describes setting up a new PDR for management through HP SIM: 1. The HP PDR Management Module is installed and connected into the management network used by the HP SIM server. 2. HP SIM is launched and automatically detects the new management module. 3. The HP SIM All Systems page lists the newly detected management module with a hyperlink to its web interface. 4. The facility manager launches the web interface of the newly discovered module and configures the module to send SNMP traps the server running HP SIM. An SNMP trap sent to HP SIM can include a URL that allows a facility manager to launch the web interface of the originating management module and open the specific page for the event. A trap resulting from a tripped circuit breaker, for instance, can include the URL for the PDR breakers Panel 1 page (Figure 7) of the web interface for quick review of the problem. Note The correct MIB file (cpqpower.mib) must be compiled into HP SIM before traps can be received. The HP Power MIB file is available from the following HP web site: http://h18013.www1.hp.com/products/servers/management /hpsim/dl_windows.html ModBus support The HP PDR Management Module supports ModBus protocol. ModBus is an industry-standard communications protocol for monitoring and managing facility devices. The HP PDR Management Module supports both ModBus/RTU (serial) and ModBus/TCP (Ethernet) protocols, although only one ModBus protocol can be used at a time. The management module includes over 140 ModBus data register and alarm types, and therefore provides much of the functionality of the web interface. Information such as monthly/yearly/total kW hours per breaker is recorded, and alarms such as input/output voltage and current warnings are triggered when thresholds are exceeded. Conclusion A data center's power infrastructure has become as important as the IT equipment it supports. A zoned distribution system incorporating the HP PDR with remote management allows the facility manager to precisely monitor and control power to avoid unscheduled downtime and wasted power. 11
