SERVSWITCH™ QUICK INSTALL GUIDE

5.The RS-232 Connection (Required for Upgrading Firmware, Optional Otherwise)

To attach the ServSwitch’s RS-232 port to the RS-232 serial port of a PC or modem for upgrading firmware (required) or for out-of-band port switching and diagnostics (optional), you will need a 4- or 6-wire flat-satin modular cable and a modular adapter:

If you are connecting the Switch directly to a DB9 male computer serial port, use the 4-wire cable and the DB9 female adapter that came with the Switch, as shown in Figure 12. (If you lose the cable, you can replace it with our product code EL04MS. If you lose the adapter, you can replace it with our product code FA043.)

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.
