SERVSWITCH™

3.2.3CONNECTING CPUS

CPU Adapter Cables run from the ServSwitch to the keyboard port, mouse port, and video-output port of each CPU you want to directly attach to it. Different types of this cable fit the connectors on different computers (see Appendix B). This cable also comes in the different lengths supported by different applications (see Section 4.1.3).

CAUTION!

Avoid routing cable near fluorescent lights, air - conditioning compressors, or machines that may create electrical noise. Total length of original Serv cable from the ServSwitch to any attached device (keyboard, monitor, mouse, CPU, or submaster) should not exceed 20 ft. (6.1 m); total length of original Serv cabling from any CPU to any keyboard, monitor, and mouse shouldn’t exceed 40 ft. (12.2 m). For typical equipment and video resolutions, length of coaxial cable should not exceed 20 ft. (6.1 m) from a ServSwitch to any attached device. However, we do provide coaxial cable in lengths up to 100 ft. (30.5 m), because some CPUs can drive and receive keyboard and mouse signals at greater distances than others. To go even farther, you might want to use Station Extenders or CAT5 KVM Extenders (see Appendix B).

1.After you verify that the Switch is turned off and unplugged, plug the DB25 male connector of the first CPU’s CPU Adapter Cable into the lowest- numbered CPU port on the Switch’s rear panel that isn’t going to be occupied by a submaster Serv type switch. Use consecutively higher-numbered ports for the rest of the CPUs. For example, if you planned to put three submasters and three CPUs on an 8-port master Switch, you would put the submasters on ports CPU 1 through CPU 3 (see Section 3.2.4), and you would plug the three CPUs into ports CPU 4 through CPU 6.

2.Plug the CPU Adapter Cable’s video-, keyboard-, and mouse-port connectors into the corresponding ports on the CPU. The CPU should be OFF when you do this; the Switch will automatically adjust to the CPU’s keyboard mode when you power up the CPU. Avoid plugging CPUs into the ServSwitch if they are already ON; if you accidentally do so, see Section 5.3.2 to make sure the Switch is set for the proper keyboard mode.)

CAUTION!

Do not attach docking stations for ThinkPad® or other portable computers, no matter what type or make, to the ServSwitch. It does not support docking stations; your Serv system might not function properly if any are attached.

Even if you connect your ThinkPad directly (rather than through a docking station) to the keyboard, video, and mouse feeds from the ServSwitch, it still won’t work, because the ServSwitch supports only “stream mode” (continuous) mouse data but the ThinkPad has to see “prompt mode” (burst-on-request) mouse data.

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.
