ACTIVE STAR HUB

5. Installation

IMPORTANT!

If you haven’t already done so, please read the safety guidelines listed on page 1.

1.The Active Star Hub is designed to be placed in a 19" rack. The unit should be properly installed using all four mounting holes. Rack hardware is not provided. (For more information on rack hardware that will work with this unit, call Black Box Technical Support at 724-746-5500.) We recommend that you use plastic or nylon washers under mounting screws to protect the Hub’s finish.

2.The external power supply is mounted on the rear panel of the Active Star Hub. Insert the AC power cord firmly into the external Power supply.

3.Insert the male end of the AC power cord into a properly wired receptacle. All data and mode LEDs on the Active Star Hub will light for two seconds and fade. The amber Power LED on the front panel and the green Power LED on the top of the external power supply will light and remain on.

4.The devices attached to each star segment must have unique addresses. Connect all the devices to the Hub’s jacks. The LEDs may momentarily blink as cables are attached. All Device Activity LEDs should be off. If any Device Activity LED remains on or flashes, refer to Chapter 6, Troubleshooting.

5.Connect the host to the host ports of the Active Star Hub. All Activity LEDs will sequentially light and remain on. If a port and its devices are Express- ready, then the Express data rate will activate and the Express mode LED will light. If any Activity LED does not remain on or flashes, refer to Chapter 6, Troubleshooting.

NOTE

The Express and standard modes are mutually exclusive at the port level. The AS/400 operates a port at the standard rate whenever a standard rate device is detected. The AS/400 operates in the Express mode when all of the attached devices are Express capable.

RJ-45, RJ-11 specifications

The Black Box RJ-11 and RJ-45 connectors are essential components in modern telecommunications and networking, facilitating connectivity in both telephone systems and data networking environments. These connectors ensure reliable and efficient communication across various devices and networks, boasting a range of features and characteristics that cater to diverse requirements.

The RJ-11 connector is primarily used in telephony systems. Typically, it comprises a 6-position, 2-contact design, although it can also be found in 4- and 6-contact variants. The standard RJ-11 is compatible with telephone lines, allowing for easy connection of telephones, modems, and fax machines. Its compact size and simple design facilitate straightforward installation and replacement. The most notable feature of the RJ-11 is its ability to support voice transmission with a frequency range typically up to 1 MHz, which is adequate for standard phone conversations. The connector's design also minimizes interference and provides secure connections, enhancing call quality.

In contrast, the RJ-45 connector is widely recognized in networking applications, particularly Ethernet networks. This 8-position, 8-contact (8P8C) connector is fundamental for data transmission over Local Area Networks (LANs). The RJ-45 supports various Ethernet standards, including 10BASE-T, 100BASE-TX, and 1000BASE-T, allowing for data rates ranging from 10 Mbps up to 10 Gbps, depending on cable and equipment compatibility. One of the defining characteristics of the RJ-45 is its ability to accommodate shielded and unshielded twisted-pair cabling (STP and UTP), which helps reduce electromagnetic interference, thereby enhancing network stability and performance.

Both RJ-11 and RJ-45 connectors are designed for durability and longevity. They feature robust construction materials that resist wear and tear, ensuring consistent performance over extended use. Moreover, both connectors are easy to install and come with various cable assemblies and adapters to cater to different environments and requirements, providing flexibility and convenience for users.

As technology continues to evolve, the RJ-11 and RJ-45 connectors remain crucial in maintaining seamless communication and data transfer capabilities, serving as reliable interfaces in an increasingly interconnected world. With their distinctive features and reliable performance, these connectors will continue to play a vital role in both telephony and networking applications for years to come.
