WTI's VMR-8H20-ATS-1 Outlet Metered Switched PDU with automatic transfer switching is the perfect solution for critical network installations that require remote power control and power supply redundancy on 120V AC equipment. WTI's VMR series metered PDUs help you keep track of conditions at your data center, and can automatically notify you before things get out of hand. The VMR also allows you to automatically reboot outlets when attached devices cease to respond, disable outlets to reduce current consumption or switch on cooling devices to lower rack temperatures.

A comprehensive selection of monitoring features is also included; event alarms, outlet-specific metering, SNMP polling and other alarm functions help you to keep tabs on vital network elements, avoid costly service calls and maximize up time.

Automatic Transfer Switching
outlet metered pdu with built in ATS

The VMR-8H20-ATS-1 includes a built in power transfer switch for automatic power fallback, providing a perfect remote reboot solution for applications that require power redundancy. The ATS feature also simplifies the challenge of ensuring power redundancy for single inlet devices; all devices that draw power from the VMR-ATS benefit from its power transfer capabilities. In the event that your primary power supply fails, the VMR-ATS will instantly detect the failure and automatically switch to the secondary power supply in less than 16 milliseconds.

Versatile Alarm Functions for Automatic Reboot and Power Switching

In addition to performing on-demand power switching, the VMR-8H20-ATS-1 also includes a poweful assortment of alarm functions, which can automatically reboot or switch outlets when high rack temperatures, open circuit breakers, power supply irregularities, unresponsive network elements and other significant events and conditions are detected. When alarm functions are triggered, the VMR-8HD20-ATS can provide notification via email, SNMP trap or SYSLOG message. Each alarm can be customized to select triggers and response actions to fit your application.

Security and Co-Location

The VMR-8H20-ATS-1 also includes a formidable array of security, authentication and co-location features to ensure that access to critical command and configuration functions is thoroughly protected from unauthorized access. In addition to password protection, the VMR-ATS also supports HTTPS, SSHv2, SNMPv3, TLS, IPSec, OpenVPN as well as popular authentication protocols such as LDAP, Active Directory, Kerberos, RADIUS and TACACS+.

The VMR's user account directory provides four different access levels; Administrator, Super User, User and View Only. Each account level enables the user to access to a different set of command, view or configuration capabilities. Higher level users can be granted access to all command, status and configuration functions, while lower level users can be limited only to control functions or status display capabilities.

Supports DUO Technology Radius 2FA

DUO is a cloud based two factor authentication (2FA) service that corroborates the identity of each logon to ensure that users are actually who they claim to be. When a user enters an account name and password to logon to the VMR, DUO then re-authenticates the user’s identity via mobile phone or other device. This effectively shifts access protection from a perimeter based approach that relies on the privacy of the user’s logon credentials, to an application based security solution that requires additional interaction from the user before access is granted.

SAN Certificate Support

In order to help simplify configuration and setup of SSL communication, VMR Series Products now support Subject Alternative Names (SAN). SAN is an extension to SSL X.509, that allows a selection of additional host names (DNS names, IP Addresses, Email Address and URIs,) to be protected by a single SSL Certificate. Subject Alternative Names allow you to perform virtual hosting of multiple SSL sites on a single IP address and eliminate the hassles involved in configuring multiple IP addresses on your server.

Zero-Touch Provisioning (ZTP)

Zero-Touch Provisioning (ZTP) simplifies day 0 onboarding of VMR units and in many cases, eliminates the need to have an engineer present during initial set up. If configuration information is not detected during boot up, Zero-Touch Provisioning will be activated and the device will contact a DHCP server and then download a configuration script and perform a firmware update without user intervention. This drastically reduces service interruptions due to human error and cuts the time required to set up newly installed VMR Series products.

Includes Enterprise Management Software

All WTI console server and switched PDU products include our convenient WMU Enterprise Management Solution, to drastically simplify the task of managing WTI devices spread throughout your network infrastructure. The WMU provides a centralized command interface, allowing administrators to easily manage, label and control multiple WTI console servers and switched PDUs in large network applications, reducing the time required to access console port command and power control functions for specific devices. The WMU Enterprise Management Solution can also control firmware updates for WTI products and edit and manage user accounts at individual WTI devices or for all WTI devices throughout your network.

Reliability and Support

The VMR-8H20-ATS-1 is built in the USA and backed by a five year warranty. WTI products are installed in thousands of network sites worldwide. Our customers know they can depend on WTI for superior quality and reliability for their most mission-critical operations.
