Stackable Personal Hubs 2.0 Installation and User Guide (04/01) INTRODUCTION This section describes the ST80 Stackable Personal Hub, including appearance, features and possible applications. 2.1 Inspecting the Package and Product Examine the shipping container for obvious damage prior to installing this product; notify the carrier of any damage which you believe occurred during shipment or delivery.
Stackable Personal Hubs 2.2 Installation and User Guide (04/01) Product Description The Stackable Personal Hub is an eight-port + 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. Up to five Stackable Personal Hubs may be stacked to form a single logical repeater. Personal Hubs are standard physical layer Ethernet products and operate independently of all software.
Stackable Personal Hubs Installation and User Guide (04/01) ST80 Personal Hubs fit easily into the workplace environment. They are versatile enough to be table-top or shelf-mounted. Alternatively, the brackets included in the package may be used to mount a single (un-stacked) unit on a wall or any suitable vertical surface. All of the wiring connectors are in the same plane so that wiring space is neat and minimal.
Stackable Personal Hubs Installation and User Guide (04/01) The external power supply unit supplied is one of two types; one version for AC input power of 115 vac 60 Hz, and one version for 230 vac 50 Hz. The 115 vac version has a small transformer integral with a convenience power outlet plug. The 230 vac version has a small transformer integral with an IEC-type power plug for a usersupplied AC power cord with a convenience power outlet plug.
Stackable Personal Hubs 2.3 Features and Benefits ν Expandable Design Installation and User Guide (04/01) When network needs grow, several Stackable Personal Hubs can be easily stacked to form a single logical repeater of up to forty RJ-45 ports.
Stackable Personal Hubs 2.4 Installation and User Guide (04/01) Applications Expanding from one to multiple ports at an existing site is easy, and requires no modification to typical building wiring. Simply plug the existing networked device's network cable into one of the ST80’s front RJ-45 ports. The Up-Link port (with switch set to “X”) connects via 10BASE-T cabling to the existing network outlet.

Stackable Personal Hubs 3.0 Installation and User Guide (04/01) Installation Installation of a Stackable Personal Hub is a simple procedure. First, locate an AC receptacle that is within six feet (2 meters) of the intended hub location and plug in the external power supply unit (provided as part of the unit).
Stackable Personal Hubs Installation and User Guide (04/01) The rugged steel case of the ST80 Personal Hub will protect it from accidental damage in an office or lab workplace setting. Keep an open area around the unit so that convection cooling can occur while the unit is in operation. 3.

(The brackets and screws included with the bottom unit of the stack will not be used for stacking purposes.) 3.4 Twisted Pair Segment Connections 1. Using standard 10BASE-T media, Proper attachment of ST80s with stacking/mounting bracket insert the male plug on one end of the network cable into one of the RJ-45 female ports on the Stackable Personal Hub.
Stackable Personal Hubs Installation and User Guide (04/01) The AUI port may also used for connecting to other Ethernet devices using standard AUI cabling. In this type of situation, it is important to consider the AUI segment length to the attached device, including any cascading. The maximum transmission distance between a backbone transceiver and the AUI port of the ST80 will vary.
Stackable Personal Hubs 3.6 Installation and User Guide (04/01) BNC Connection (Model ST80-B only) Connect the ThinNet coax cable to the BNC connector on the rear of the ST80-B in the same manner as is done for any standard BNC connection. The BNC port is specially equipped with an internal termination switch that eliminates the need to use a "tee" connector when the BNC cable is ending at the ST-80. When the switch is in the right position, the connection is internally terminated.
Stackable Personal Hubs 3.8 Installation and User Guide (04/01) Switchable Up-Link Feature Each Stackable Personal Hub is equipped with an up-link switch, connected to port 8 (right-most RJ-45 port). This switch is used to select either a normal 10BASE-T connection to a user device (switch in the “==” position) or a 10BASE-T network up-link connection to another hub or concentrator (switch in the “X” position).
Stackable Personal Hubs Installation and User Guide (04/01) When stacking, switch the Stack Enable switch of the bottom IR B1 PWR IR B2 le ab N En O ck Sta FF O ST80 to the “OFF” position (left). All AUI Magnum ST80 Stackable Personal Hub UP-LINK Ports 1 2 3 4 5 6 7 8 other units should be switched to the “ON” position (right).
Stackable Personal Hubs 3.10 Installation and User Guide (04/01) Cascading the ST80 Personal Hub with the Up-Link port Stackable Personal Hubs may be cascaded in order to expand existing networks. For example, an ST80 may be cascaded via the switchable up-link port into any port of another hub. Also, Stackable Personal Hubs may be connected to a backbone via the rear AUI port. With the addition of a mini-transceiver, the AUI port may be used to connect to any standard Ethernet media.
Stackable Personal Hubs 4.0 Installation and User Guide (04/01) OPERATION This section details the various operational features of Magnum ST80 Personal Hubs, including a description of the LED indicators. Stackable Personal Hubs are fully compliant with the Ethernet Version 2/IEEE 802.3 Repeater Specification for CSMA/CD 10 Mbps operation and will function accordingly. 4.1 Functional Operation, Use of LED Indicators Power On (PWR) LED: Illuminates GREEN to show proper DC power.
Stackable Personal Hubs Installation and User Guide (04/01) Preamble Regeneration: Stackable Personal Hubs add preamble bits so that output packets contain a minimum 64-bit preamble per the Ethernet standard. 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.
Stackable Personal Hubs 4.4 Installation and User Guide (04/01) Using the Stack Enable switch The Stack Enable switch of the ST80 is used to configure each unit of the stack. If an ST80 is being used as a non-stacked unit, the Stack Enable switch must be in the “OFF” position. When two or more ST80s are stacked, the bottom unit should be set to the “OFF” position, and all other units should be in the “ON” position. For further information about the Stack Enable switch, see Section 3.
