Black Box Explains...Link loss.

Media converters solve the problem of connecting different media types in mixed-media networks. In order to comply with IEEE standards, they implement IEEE data-encoding rules and the Link Integrity Test.

For... more/see it nowa twisted-pair segment, a link is a signal sent by the converters when the cable is in use. If no Link Integrity Test signal is received, the connected device assumes that the link is lost.

With fiber cable, a connected device checks a line by monitoring the Link Integrity Test signal from the converter and the power of the light being received. If the light’s power drops below a certain threshold, the link is lost. In either case, link loss usually results from a broken cable, which is the cause of approximately 70% of all LAN problems.

Link loss is often indicated by an LED on a connected network device. You can also monitor a link with network-management software, such as SNMP, which sends a TRAP (alert) to the management workstation when the link is lost.

Media converters actually function as two separate Multistation Access Units (MAUs). For example, one monitor is a twisted-pair segment and one monitor is a fiber segment. If a fiber cable is broken and the link is lost, a network manager on the twisted-pair end won’t know there’s a problem until users on the fiber side report it.

To solve this problem, Black Box® Modular Media Converters feature a unique Link-Loss capability. This enables the link status on one segment to reflect the link status of the other segment. So if the link is lost on the fiber side, the link is disabled on the UTP segment as well. And the converters will send an SNMP TRAP indicating the loss of link to the management workstation. collapse

Black Box Explains…Wizard.NET

One software solution to rule them all.
Wizard.NET is a professional enterprise management suite that delivers total IP device control, management, and connectivity. Black Box KVM over IP (KVMoIP) devices provide... more/see it nowthe ability to control large numbers of host computers from remote locations. When controlling larger groups of dispersed computers using numerous KVMoIP devices, the major challenge becomes one of management—retaining active control over a complex mix of devices, host computers, and registered users. Wizard.NET was developed as a common interface to help you remotely manage any number of KVMoIP devices together with all of their connected host computers and the access rights of the users.

Wizard.NET is delivered as a software solution only, and operates as a server application running on a system that can be completely separate from any of the KVMoIP devices?—?it merely requires an IP network or Internet connection. Wizard.NET uses an intuitive HTML user interface, which means that registered users can access and control it remotely using a standard Web browser. Like all Wizard KVMoIP products, Wizard.NET employs high specification security techniques to ensure that only authorized users may gain access.

Wizard.NET has two main modules, the manager and the connector. The manager module is accessible only to managers and administrators. It is where the details about all connected devices, hosts, and users are configured and stored. The connector module can be used by registered users to enable quick access to all of the targets for which they have access rights. Targets may be devices, hosts, or device groups as appropriate.

To ensure maximum security, Wizard.NET does not retain any passwords within its database for the devices that it controls. Instead, a valid password is used once only to gain access to each device during the “acquire” stage, when Wizard.NET establishes a Secure Ticket with the device. In all subsequent accesses to each device, the relevant secure ticket is used to gain access. collapse


Mounting flat-screen displays.

Traditionally, computer monitors, TVs, or other video displays have simply been placed on a shelf or desktop. However, today’s flat screens are less stable than older vacuum-tube displays and should... more/see it nowbe secured to prevent tipping. Fortunately, most new displays meet the VESA standard, meaning they have a hole pattern on the back that fits any VESA standard mounting device such as a wall mount, desktop mount, or ceiling mount. This enables you to secure the display to prevent damage from accidental jolts and bumps. Additionally, a mounted display is less likely to be the object of theft. collapse
