CHAPTER 3: Installation

CAUTION!

Do not attach docking stations for older models of the ThinkPad® or other portable computers to the ServSwitch Jr. MP. The Switch currently supports only “stream mode” (continuous) mouse data, but older ThinkPad models have to see “prompt mode” (burst-on-request) mouse data. Some newer docking stations and some newer ThinkPad models might work with the Switch, but determining whether a particular unit will do so will probably require trial and error.

3.4 Powering Up the System

To connect the power supply, first insert the plug of the power supply’s output cord into the 3.5-mm barrel jack on the rear panel of the ServSwitch Jr. MP. Then plug the IEC 320 female outlet on one end of the power supply’s detachable input cord into the IEC 320 male inlet on the supply’s transformer. Finally, insert the country-specific plug at the other end of the input cord into a working utility- power (mains) outlet. The Switch will begin operating immediately; it has no ON/OFF switch.

Now power up the connected CPUs one by one, giving each one time to boot completely before turning ON the next one. (If you’re not using the power supply, the ServSwitch Jr. MP itself will begin operating as soon as you turn ON the first CPU; it will get its power from the CPUs and has no ON/OFF switch.) To boot a Mac using a 101- or 102-key PC keyboard, first boot an attached PC, then select the CPU port of the Mac, then press the right Control ([CTRL]) key (see

Section 4.3.12 for a full list of remapped keyboard keys). The Switch emulates all keyboard and mouse functions for automatic boot-up, although you might have to issue the Mode command Mn (see Section 4.3.10) to get proper keyboard communication with your PC CPU(s).

3.5 Switching from the Keyboard

Your ServSwitch Jr. MP is now ready for operation using its default settings. To take full advantage of the Switch’s features, refer to Chapter 4, which gives detailed information about each of the Switch commands, describing each command’s function and keystroke sequence. For your convenience, this information is summarized in Section 4.2. To begin switching immediately, however, just press and release your keyboard’s left Control ([CTRL]) key, then—within the next two seconds—type in your desired port number with the regular number keys (not the numeric keypad).

SW627A-R2, SW628A-R2 specifications

The Black Box SW627A-R2 and SW628A-R2 are advanced network switches designed to enhance the efficiency and reliability of modern data networks. These switches are ideal for various applications, including data centers, enterprise networks, and industrial settings, providing robust performance and flexibility for a wide range of tasks.

The SW627A-R2 model features 24 Ethernet ports, allowing for seamless connectivity across a broad array of devices. Its 10/100/1000 Mbps auto-sensing capabilities ensure that all connected devices can communicate effectively, making it an excellent choice for businesses looking to maximize their existing infrastructure. The switch is designed with energy efficiency in mind, featuring IEEE 802.3az Energy Efficient Ethernet technology. This integration helps in reducing power consumption and minimizing operational costs without compromising performance.

On the other hand, the SW628A-R2 model takes things a step further by offering 48 ports, accommodating even larger networks with ease. This switch also supports Power over Ethernet (PoE), which allows it to deliver power to connected devices such as IP cameras, VoIP phones, and wireless access points, eliminating the need for additional power sources and simplifying network installation.

Both models support Layer 2 switching and feature advanced forwarding techniques such as store-and-forward and cut-through modes. They also come equipped with a user-friendly interface for easy configuration and management, with options for SNMP monitoring to ensure optimal performance and troubleshooting capabilities.

From a security perspective, both the SW627A-R2 and SW628A-R2 incorporate features such as VLAN support, port security, and access control lists (ACLs). These features help in segmenting network traffic, preventing unauthorized access, and enhancing overall network integrity.

In terms of durability, both switches are designed for robustness, with sturdy enclosures suitable for various environments. The fanless design also ensures silent operation, making them suitable for office settings.

Overall, the Black Box SW627A-R2 and SW628A-R2 network switches are designed to meet the demands of advanced networking environments, providing the necessary features and technologies to facilitate efficient, secure, and scalable operations. Whether for a small business or a large enterprise, these switches provide a reliable backbone for any network infrastructure.
