Do you need an efficient, cost-effective way to distribute, monitor and manage power in an IT environment? Tripp Lite's PDUMH20NET Switched/Metered Power Distribution Unit is the solution you seek! Featuring a built-in SNMPWEBCARD, the PDUMH20NET provides full remote power monitoring and control via a secure network or web browser interface. Used with an optional environmental sensor module (Tripp Lite model ENVIROSENSE), the PDUMH20NET can also provide temperature/humidity and dry contact interfaces monitoring. The PDUMH20NET's sixteen outlets are individually controllable to enable load shedding, load ramping and remote rebooting of locked-up servers and other network devices. Its circuit breaker-free design prevents power interruptions due to tripped breakers. These capabilities provide IT personnel with enhanced oversight of facility power and environmental conditions. The PDUMH20NET is configurable for 1U rackmount installation with included hardware.


PDUMH20NET Applications

Advanced Network Monitoring Capabilities

The PDUMH20NET gives IT personnel enhanced oversight of network power conditions. It remotely monitors site power conditions and PDU load levels, and supports notification and logging of all major power events and user-specified alarm thresholds via email or SNMP traps. Real-time clock backup maintains the time of day and date even if the PDU is shut down and unpowered. Used with Tripp Lite's optional ENVIROSENSE sensor, the PDUMH20NET can also remotely monitor temperature/humidity conditions plus up to four dry contact interfaces for alarm, security and telecom devices. These capabilities simplify and streamline the task of network power management.

PDUMH20NET Feature Focus

Built-In Network Interface with Broad Compatibility

The PDUMH20NET features a built-in SNMPWEBCARD that enables full remote access for power monitoring, configuration and control via a secure network or web browser interface. The PDUMH20NET provides 10/100 Mbps auto-sensing for optimal communication compatibility with a 10/100 Base-T network. Protocols supported include HTTP, HTTPS, PowerAlert Network Management System, SMTP, SNMPv1, SNMPv2, Telnet, FTP, DHCP, BOOTP and NTP. DHCP/Manual configuration support provides the ability to have network settings automatically assigned to the card, or manually assigned via permanent IP addresses.

Remote Outlet Control

The PDUMH20NET's sixteen 5-15/20R outlets are individually controllable via network or web browser interface, providing a higher level of network power control. These outlets can be controlled in real-time to remotely reboot unresponsive network hardware, or be custom programmed for user-defined power-up and power-down sequences to ensure proper startup of interdependent IT systems and prevent inrush-related overloads as network equipment is first energized. Unused outlets can be disabled to prevent the connection of unauthorized equipment loads.

Sequentially Activated Outlets

To prevent inrush-related equipment interaction at startup, the PDUMH20NET's sixteen 5-15/20R outlets are factory-programmed for sequential activation at 250-millisecond intervals when the PDU is energized.

Digital Load Meter and Outlet LEDs

To prevent potential overloads before critical IT main or branch breakers trip, the PDUMH20NET is equipped with a digital LED meter that enables IT personnel to monitor the total load on the PDU in real time. This meter helps to assure that the PDU is used at maximum capacity with no danger of overload. Each outlet is provided with an LED that illuminates to confirm power on/off status.

Network interface and Digital Load Meter

Optimized for Demanding Applications

The PDUMH20NET is designed for reliable distribution of AC power to supported equipment in IT, industrial and similar applications. It features a rugged all-metal case, high-quality outlets, a locking plug and a switchless, circuit breaker-free design with included cord retention brackets to prevent accidental shutoff.

Versatile Installation Options

The PDUMH20NET is easy to integrate with a wide range of data center and network applications. It is suitable for 1U installation in standard 19-inch rack enclosures as well as wall-mount, workbench, under-counter and similar installations.

Peace of Mind

The PDUMH20NET comes with a 2-year manufacturer's product warranty.
