CHAPTER 2: Introduction 2. Introduction 2.1 General Overview The 9-Port Personal MiniHub is a workplace hub in a very compact package. It is simple to install and use in an office or lab environment, requiring no special rack cabinets or wiring-closet apparatus. It is a standard physical-layer Ethernet product and operates independently of all software. Personal MiniHubs provide a simple and inexpensive solution for networking a personal multi-system office using 10BASE-T twisted-pair cabling.
-PORT PERSONAL MINIHUB specification for repeater functionality: They perform signal amplification, retiming of data packets, and regeneration of preamble bits for each packet received. They will also detect collisions, extend collision fragments, and automatially partition and reconnect individual ports in order to keep problems on one segment from causing downtime elsewhere on the network.
CHAPTER 2: Introduction • Installation Versatility You can easily install Personal MiniHubs in almost any office or lab location. The tiny package is very unobtrusive and is typically mounted with Velcro. • Robust Netork Operation Personal MiniHubs use the “star” network topology and have automatic per-port partitioning and reconnection. A fault on one segment is isolated from the rest of the network, avoiding most network downtime.
9-PORT PERSONAL MINIHUB To Existing Network 9-Port Personal MiniHubs may also be used standalone to network a local personal multi-user system, as shown below. Up to nine RJ-45 user ports are available where only 10BASE-T wiring is used, and full-length Ethernet segments are supported on all segments. In this application, set the Up-Link switch to the straight-through or “===” position, so that the MiniHub’s rear port is a user port, not an up-link to another hub.
CHAPTER 3: Installation 3. Installation 3.1 Before You Install: Inspecting the Complete Package Examine the shipping container for obvious damage prior to installing this product; notify the carrier of any damage which you believe occurred during shipment ar delivery. Inspect the contents of this package for any signs of damage and make sure that you received these items: • (1) 9-Port Personal MiniHub • (1) External 120-VAC 60-Hz power supply • (1) Velcro tape section, approximately 3 inches (7.
9-PORT PERSONAL MINIHUB Wall (or Vertical-Surface) Mounting The 9-Port Personal Hub comes with a piece of Velcro mounting tape. You can use this to mount a Personal Hub in a vertical position. Stick one side of the Velcro to the bottom of the hub between the rubber feet. Stick the other side of the Velcro to the desired vertical mounting location.
CHAPTER 3: Installation 3.2.3 CONNECTING TWISTED-PAIR SEGMENTS TO THE FRONT-PANEL PORTS 1. Insert the male plug on one end of a standard 10BASE-T cable into one of the RJ-45 female ports on the front panel of the 9-Port Personal MiniHub. (Even though the MiniHub’s connectors are shielded, they will accept, and operate properly with, either unshielded- or shieldedtype RJ-45 twisted-pair wiring plugs.) 2. Connect the other end of each network segment to a workstation or user device.
9-PORT PERSONAL MINIHUB 3.3 Cascading You can cascade 9-Port Personal MiniHubs in order to expand networks. For example, you can set a MiniHub’s Up-Link switch to the “= =” position, then run 10BASE-T cable from the MiniHub’s rear-panel port to any port of another 10BASE-T hub, as shown in the illustration below. Since each 9-Port Personal MiniHub provides full repeater functionality, cascaded units can operate together even though there may be a full segment of distance between them.
CHAPTER 4: Operation 4. Operation This chapter describes the LEDs and operating features of the 9-Port Personal MiniHubs. The 9-Port Personal MiniHubs are fully compliant with the Ethemet Version 2/IEEE 802.3 Repeater Specification for CSMA/CD 10-Mbps operation and will function accordingly. 4.1 LED Indicators Power On (PWR) LED: Shines GREEN to show functional DC power.
9-PORT PERSONAL MINIHUB Prenmble Regeneration: As per Ethernet standards, the 9-Port Personal MiniHubs add bits to the preambles of output packets so that each output packet contains a minimum 64-bit preamble. Collisions: When carrier is detected simultaneously on multiple ports, a jam pattern is generated on each port to create a collision condition. When a collision signal from one port is detected, it generates a jam pattern to other ports.
CHAPTER 5: Troubleshooting 5. Troubleshooting Should problems develop during the installation or operation of your 9-Port Personal MiniHub, this chapter should help to locate, identify and correct such problems. Please follow the suggestions listed in Section 5.1 below. If nothing helps, contact your supplier; see Section 5.2. 5.1 Things to Check 1. If you a problem installing or operating the 9-Port Personal MiniHub, refer back to Chapters 3 and 4.
9-PORT PERSONAL MINIHUB 5.2 Calling Your Supplier If you determine that your 9-Port Personal MiniHub is malfunctioning, do not attempt to alter or repair it. Contact your supplier. The problem might be solvable over the phone. Before you do, make a record of the history of the problem. Your supplier will be able to provide more efficient and accurate assistance if you have a complete description, including: • The nature and duration of the problem. • When the problem occurs.
