VMR-HD High Amp Metered + Switched PDU

At a glance

Uniquely Designed
The VMR-HD High Amp Metered + Switched PDU is specifically designed to provide comprehensive power management and control for high amp, enterprise class networking equipment such as Cisco Nexus C7000 Switches, HP 7000 Blade Servers, Cisco Catalyst 6500 LAN switches and Sun Blade 6000s. You can now protect the multi power supply architecture of all your critical IT hardware with just one power controller.

Power Supply Redundancy
The VMR-HD has dual 16 amp or dual/quad 32 amp power inputs, with (4), (8) or (12) C19 outlets. This multi power input architectures makes the VMR-HD ideal for managing high amp, multi power supply enterprise class networking equipment such as catalyst switches and blade server chassis, where multi power supply redundancy is an essential requirement. The latest VMR-HD4D32-8 can support a full 16 amp load on each of its (8) C19 outlets simultaneously.

Horizontal Design
It is not easy to install one, let alone two, switched PDUs into an already cramped rack cabinet. The depth of high end enterprise networking equipment chassis means that there is little or no space to mount a vertical PDU at the rear of a cabinet. The VMR-HD is horizontally rackmountable, ensuring that it will easily fit into your equipment rack when space is tight.

Complete Power Management
The VMR-HD High Amp Metered + Switched PDU gives you an unrivalled ability to manage, monitor, report and control power in each of your racks, wherever they are located. With its dual power input feeds for full power
redundancy, comprehensive reporting, power control including reboot, load shedding and scheduled on/off switching, temperature monitoring, event logging and proactive alarm notification, the VMR-HD is a complete power solution for all your power management needs.


Features & Benefits

The VMR High Amp Outlet Metered Switched PDUs are specifically designed to provide secure, remote power control,metering and reboot capabilities for high amp devices such as Cisco Catalyst 6500 LAN Switches, Cisco Nexus 7000 Data Center Switches and HP C7000 Blade Servers.

The dual power supply on the VMR protects the redundant power supply architecture of your larger dual powered servers. A dual power supply server can be supported across the dual bus architecture of the VMR so that you can maintain full redundancy without having to install two separate power switches.

The VMR-HD4D30 features four 32 Amp inputs, (8) eight individually metered and switched IEC C19 outlets and (8) eight 16 Amp UL-489 circuit breakers. Each circuit breaker protects one IEC C19 outlet and supports up to 16 Amps.

The VMR can generate alarms to provide you with an advanced warning of problems with your equipment such as lost voltage or high rack temperatures. Alarms can be sent by email, SNMP, SYSLOG or audibly. This will increase network availability by allowing you to proactively identify issues before they become critical.

When enabled, the unit will also ping IP addresses according to a set schedule and if the device fails to respond, you will be alerted.

The VMR will constantly monitor your remote rack temperature level with its integral temperature sensor. If the temperature exceeds your pre-defined thresholds, you will be notified and the VMR can, if necessary, turn on external fans or air-conditioning to help bring rack temperature back to normal levels.
