CHAPTER 2: Introduction

2.5 Cable Requirements

Many switches of this type have what seems like ten million connectors on their rear panels: one for each CPU’s video cable, one for each keyboard cable, and a third for each mouse cable. The potential for tangling or mismatching cables is high.

By contrast, you can connect the ServSwitch to your CPUs with one “CPU Adapter Cable” for each CPU. This single cable reaches the CPU’s video-output, keyboard, and mouse ports.

Likewise, to connect “submaster” (slave) Serv type switches, you need one “ServSwitch-to-ServSwitch Expansion Cable” for each subsidiary unit.

Lastly, you can connect the ServSwitch to the shared monitor, keyboard and mouse with a single “MKM Adapter Cable.”

The exact variety or varieties of these cables that you’ll need will depend on the equipment you are connecting for your application. Refer to Appendix B for the available types of these cables and the corresponding product codes. Also refer to Chapter 1 or the first Caution notice on page 22 for information about maximum cabling distances.

NOTES

SVGA (over longer distances) and XGA video place special demands on cabling that the regular MKM Adapter Cables and CPU Adapter Cables typically cannot meet. For these applications, you should use coaxial cables that can carry video signals not only farther but also at higher resolutions. See Appendix B and the first Caution notice on page 22.

To share an IBM 9515, 9517, or 9518 monitor on a ServSwitch, you will need special cabling. Call Black Box for technical support; we can give you a quote on these types of cable.

2.6 Equipment Requirements

If the CPUs you will be controlling through your ServSwitch are not all of the same type, you will have to be careful to choose a common monitor, keyboard, and mouse that adequately support all of the CPUs. For full details, see Section 4.1.

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.
