Operating Environment:

Ambient Temperature: 32ºF to 122ºF (0ºC to 50ºC)

Storage Temperature: -20ºC to 60ºC

Ambient Relative Humidity: 10% to 95% (non-condensing)

Power Supply (External):

Input: 95 - 125 vac at 60 Hz for "-d" Models,

200 - 250 vac at 50 Hz for "-i" Models, which have

IEC power cable connector in the external power unit.

Output: 12 VDC, 1 A

Polarity: center positive, shell negative

Power Consumption: 12 watts max.

Connectors:

ST80: Eight shielded RJ-45 ports (one with up-link switch); one rear AUI,

female, with slide lock; two Inter-Repeater-Bus connectors on the side.

ST80-B: Same as ST80, plus one rear BNC with internal termination switch.

ST80-F: Same as ST80, plus one rear Fiber ST-type.

(Shielded 10BASE-T connectors accept either unshielded or shielded wiring

plugs for standard twisted pair media wiring.)

The regular RJ-45 ports support the standard for hubs-to-users twisted

pair wiring: pin 1= receive+, 2 = receive-, 3 = transmit+, 6 = transmit-,

other pins not used. The RJ-45 port with the up-link switch is normally

the same, but when switched it supports the standard for up-links using

twisted pair wiring, i.e., the transmit and the receive pairs are exchanged:

pin 1 = transmit+, 2 = transmit-, 3 = receive+, 6 = receive- , other pins

not used.

Switches:

Up-Link: MDI-X (Media Dependent Interface - Crossover) manual slide

switch, converts RJ-45 port #8 from a regular (=) user segment port to a

crossover (X) up-link port for on-off connection to a backbone or another

cascaded hub.

Stack Enable Switch: Manual slide switch to specify which Stackable

Personal Hub is the base of the stack. Exactly one hub should have its Stack

Enable switch in the “OFF” position (left). All other hubs in the stack should

have their Stack Enable switches set to the “ON” position (right).

Internal Termination Switch (ST80-B only): When switched to the right

position, allows BNC connection without a “tee” connector and a 50 ohm

terminator. When switched to left position, a “tee” connector is required.

LEDs:

PWR: GREEN when Proper DC power supplied to ST80.

COL: YELLOW when a transmit collision occurs on the hub.

LINK/TX (per port): GREEN when link established on port. Flickers as

port transmits packets.

POL/RX (per port): Flickers GREEN as port receives packets. Steady

GREEN when reversed polarity detected.

Packaging:

Enclosure: Rugged, high strength steel enclosure.

Suitable for vertical or horizontal mounting.

Any unit may be used stand-alone, or as either the base unit or an additional

unit in a stack (two stacking / mounting clips and one IRB cable are

included with each unit)

Recessed LEDs to avoid damage, located with the RJ-45 ports for convenience.

2.2 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.

ST80 Personal Hubs are well suited for small- to-medium-size office or lab

environments (up to eight users without stacking) that need an independent Ethernet

network. They can operate as self-sufficient units to provide 10BASE-T Ethernet

connectivity for local users and devices. Small independent networks built using

Stackable Personal Hubs are easily expanded by stacking additional ST80s via the IRB

connectors. The AUI port provides backbone or other connectivity if required. (The

ST80-B and ST80-F models are also equipped with a BNC or a Fiber-ST connector for

convenient media connections.)

Stackable Personal Hubs provide a simple and inexpensive solution for

networking a multi-system office using 10BASE-T twisted pair cabling. They can

expand an existing single-network-port outlet to provide up to seven additional RJ-45

ports in the immediate office or lab area. Once installed, a Stackable Personal Hub is

easily expanded by stacking additional units to support larger numbers of users.

The Magnum ST80s’ small size makes them very useful for demonstration

situations in conference rooms and in exhibitions where a temporary network or network

expansion is needed. They are handy as a piece of test equipment that can be easily

inserted into a network to provide a test port, and then removed after the testing is done.

Stackable Personal Hubs take up minimal space, use minimal power, and are rugged

enough to be carried in a coat pocket for possible emergencies.
