The NBB-20VD16-3 includes a robust selection of monitoring features, including event alarms and SNMP polling to help you keep tabs on vital network elements, avoid costly service calls and maximize up time.

The NBB-20VD16-3 features dual 16 Amp inputs, (20) twenty remote switched IEC C13 outlets and (4) four 16 Amp UL-489 circuit breakers. Each circuit breaker protects 5 IEC C13 outlets and supports up to 16 Amps. The NBB-20VD16-3 is built for vertical Zero U (0U) installations where rack space is limited. Mounting kits are available to fit a variety of rack and closet enclosures.

The NBB-20VD16-3 can also perform remote reboots and power shutdowns on individual outlets according to a user-defined schedule, when a ping command fails or on demand.

The NBB-20VD16-3 can be configured and operated via its convenient IP web browser interface or by any SNMP MIB based enterprise management software.

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 NBB, 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, NBB 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 NBB 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 NBB Series products.

Includes Enterprise Management Software

network boot bar with enterprise management software

All WTI console server and switched PDU products include WTI’s convenient Enterprise Management Software, which drastically simplifies the task of managing multiple WTI devices spread throughout your network infrastructure. The WMU Enterprise Management Software provides a centralized command interface that allows 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 and reboot functions for connected devices.

Once installed on your PC or laptop, the WMU Enterprise Management Software can search a user-defined IP address range on your network and discover all WTI console servers and switched PDUs within the range. Discovered units are then added to the Enterprise Management Software’s inventory, allowing administrators to assign a descriptive tag to each WTI device in order to denote the location or function of the device. In addition to providing a centralized interface for remote console port access and power reboot and control functions, the Enterprise Management Software can also be used to control firmware updates for WTI products and edit and manage user accounts at individual or multiple WTI devices.
