How a Console Server Management Unit Can Make Your Job Easier

If you need secure, reliable access to RS232 console ports on remote servers, routers, firewalls and other network elements, WTI console server management products provide an ideal solution. System administrators can reduce downtime by managing and troubleshooting devices from anywhere, without the need for on-site personnel or expensive truck rolls. WTI console server management units are available in either 100-240 VAC or -48 VDC powered versions, with RJ45 or DB9 serial ports, and in 40-port, 32-port, 24-port, 16-port or 8-port configurations.

Minimize Truck Rolls

Network professionals who manage and troubleshoot network devices at remote installation sites, know how time-consuming and expensive “field trips” to remote network equipment sites can be. WTI console server management products allow you to perform many routine maintenance and troubleshooting tasks via a secure in-band or out-of-band connection, without even leaving your office. WTI console server management units include a formidable assortment of security and authentication tools to ensure that remote access to critical network elements remain secure, yet easily available to properly authorized personnel.

Reduce Downtime

WTI console server management products can constantly monitor your network equipment, watching for significant status changes and then promptly notify you via SNMP, SYSLOG, email or text message when critical events are detected. This allows prompt response to overheating racks, non-responsive devices, power outages and other potential downfalls; cutting downtime by allowing you to address problems before they get bad enough to disrupt service, plus allowing you to react quickly to any unforeseen network problems that might arise.

Intelligent Port Selection

Each RS232 serial port on the console server management unit can be individually accessed by number, name, or group via SSH or Telnet. WTI console server management products also allow direct connections using TCP port assignments. Each serial port can be separately configured using simple menu driven commands to set the port access rights, data rates, flow control and other operating parameters. Full matrix capability allows you to easily connect any two ports on the console server management unit, 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 remote locations.

Security and Co-Location

Secure Shell (SSHv2) encryption and address-specific IP security masks prevent unauthorized access to command and configuration functions. WTI console server management units also provide four different levels of subscriber access privileges: Administrator, SuperUser, User and ViewOnly level.

The Administrator level is designed for system managers and other administrators, and provides complete access to all RS232 serial ports, operating features and configuration menus. SuperUser level accounts are granted access to all serial ports and operating features and are allowed to view configuration menus, but are not allowed to change configuration parameters. User level is ideal for co-location applications; User level accounts are only permitted to view status and connect to ports that are specifically enabled for their individual account. The ViewOnly level accounts are allowed to view status menus for only the ports specifically granted to the account and are not allowed to access configuration menus.

Capture Buffer

In addition to the comprehensive assortment of communications parameters that can be defined for each console server management serial port, ports can also be configured as “Buffer Mode” ports. When the Buffer Mode is selected, the port can be used to capture and store incoming data such as error and status messages received from the attached devices. This “snapshot” of the most recently received data is stored in memory and can be viewed, saved or erased by the system operator at any time. These error and status messages can be sent to a remote manager via SYSLOG or SNMP trap, and port buffers can also be configured to generate an alarm message to alert administrators when new messages are received.
