Out of Band Console Access & Power Reboot Manager

Perfect for 120V branch office applications, the RSM-8R8-1 delivers security, accessibility and control of critical network equipment or any device with a console or maintenance port via Out of Band TCP/IP or modem connection.
The RSM-8R8-1 provides out of band remote access to multiple console ports using a secure Ethernet connection, on/off/reboot switching on specific power outlets, notification when voltage is lost, temperature alarms when user defined thresholds are breached, change configuration parameters, assign user access to ports and outlets all in a 1U device.

WMU Firmware

Dual Power Inlets for Power Redundancy and Fallback

The RSM-8R8-1 is ideal for mission critical applications, where power redundancy and fallback capabilities are required in order to ensure uninterrupted power and continuous access to command functions on vital network devices. The RSM-8R8-1 includes two power inlets to allow connection to a primary power source and a secondary power source, providing continued console port access and power availability, even if the primary power source fails. As an added benefit, the RSM-8R8-1 also serves to provide power fallback capabilities to older, single power inlet network devices that would otherwise need to be replaced in order to ensure power redundancy in mission critical applications.

Security and Co-Location

Secure Shell (SSHv2) encryption and address-specific IP security masks prevent unauthorized access to command and configuration functions. The RSM-8R8-1 also provides four different levels of user security; the Administrator, Supervisor, User and View Only level. The Administrator level, which is intended for use by system managers and other administrators, provides complete access to all port connection / disconnection functions, operating features and configuration menus, and also allows access to any port on the switch. The User level is ideal for co-location applications, since users are only permitted to view status and connect to the ports allowed by their user name and password.

Capture Buffer

"Buffer Mode" allows individual ports to capture and store incoming data, such as error and status messages received from attached console ports. This "snapshot" of the last data received is stored in memory, and can be viewed, saved or erased by the system operator at any time. Console messages can be stored in the RSM-8R8-1 port buffers, and sent to a remote location via SYSLOG, or an SNMP message can be generated to alert administrators when new console messages are received.

Intelligent Port Selection

Each serial port on your critical network devices can be individually accessed by number, name, or group via SSH or Telnet sessions. The RSM-8R8-1 also allows direct connections using TCP port assignments. Each serial port can be separately configured using simple menu driven commands to set the port password, data rates, flow control and other operating parameters.

Easily connect any two ports on the switch with full matrix capability, even when the ports are using different communications settings. Ports can also be connected or disconnected by a third party with supervisor rights, and system managers can swap various RS232 devices between ports at a remote location.

Includes Enterprise Management Software

console plus power hybrid with enterprise management software

All WTI console server products include WTI’s convenient Enterprise Management Software, which drastically simplifies the task of managing multiple console servers 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 in large network applications, reducing the time required to access console port command functions on connected devices.

Once installed on your PC or laptop, the Enterprise Management Software can search a user-defined IP address range on your network and discover all WTI console servers within the range. Discovered units are then added to the Enterprise Management Software’s inventory, allowing administrators to assign a descriptive tag to each console server in order to denote the location or function of the device. In addition to providing a centralized interface for remote console port access, 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 console servers.
