SERVSWITCH™

4.1.3MONITOR

NOTE

At resolutions up to 800 x 600, the video quality for most ServSwitch applications will be excellent. At higher resolutions, however, you might see a little fuzziness on your monitor no matter how close to ideal your ServSwitch system is.

If all of your CPUs are of the same type, we recommend that you use the corresponding type of monitor. If your CPUs are of different types, the monitor must be a multisync model, able to sync to every CPU’s video-output frequencies, and compatible with all of the CPUs’ video cards.

For maximum compatibility, we recommend a 17" or larger, high-quality multisync monitor capable of displaying a maximum resolution of not less than 1280 x 1024 at a maximum refresh rate of not less than 75 Hz. The NEC Multisync 5SG is one such monitor, and others are available from NEC, Sony®, CTX®, etc. The higher the resolution you use, the less distance you can run; see Tables 4-2 and 4-3 on the following pages.

The ServSwitch is designed to support standard VGA video, including VGA monochrome (“page white”). It does not support PCs that use CGA, EGA, or proprietary versions of VGA that depart from the original specifications. Consult your PC’s manual, and if that doesn’t tell you whether or not the PC uses standard VGA, consult with the PC’s or the video card’s manufacturer.

The ServSwitch is also designed to support SVGA, although it doesn’t handle higher resolutions or longer distances very well without coaxial cabling (see the next two pages). With coaxial cables, it will also support XGA, RS/6000, and SGI video (RS/6000 and SGI require cables with 13W3 connectors—see Appendix B).

The Black Box SW721A-R4, SW724A-R4, KV3108SA-R4, SW723A-R4, and SW722A-R4 are cutting-edge network switches that cater to the demanding needs of modern data environments. These models are designed to provide high performance, reliability, and advanced features suitable for both enterprise-level deployments and smaller networks.

The SW721A-R4 and SW724A-R4 are primarily layer 2 switches that support essential networking protocols such as IEEE 802.1Q for VLAN tagging, ensuring secure and efficient traffic management. With robust forwarding capabilities, these switches boast high-speed Gigabit Ethernet ports, which enable seamless data transfer and reduce latency in data-driven applications. Their fanless design also ensures quiet operation, making them ideal for office settings and noise-sensitive areas.

Another noteworthy addition is the KV3108SA-R4, a versatile KVM switch that provides remote management capabilities. This model can control multiple servers and computers from a single console, allowing IT personnel to streamline operations and reduce physical space requirements. With support for high-resolution video output and an intuitive user interface, the KV3108SA-R4 enhances usability while maintaining efficiency in server management.

The SW723A-R4 and SW722A-R4 models further enhance network capabilities with their advanced Layer 3 functions. These switches support static routing and dynamic routing protocols, making them suitable for complex networking scenarios. They are equipped with a comprehensive set of security features, including port security and access control lists (ACLs), ensuring that sensitive information is well-protected against unauthorized access.

All of these Black Box models operate on advanced technologies such as QoS (Quality of Service), which helps prioritize critical traffic and ensures optimal performance during peak usage periods. Additionally, they support Power over Ethernet (PoE), enabling the powering of network devices such as IP cameras and VoIP phones without the need for additional electrical outlets.

In summary, the Black Box SW721A-R4, SW724A-R4, KV3108SA-R4, SW723A-R4, and SW722A-R4 represent a fusion of performance, versatility, and security in network infrastructure. These switches are perfect for businesses looking to enhance their connectivity solutions, ensuring that they can meet the demands of an increasingly digital world while maintaining high standards of efficiency and reliability.
