Description
Magnum ST80 Stackable Personal Hubs combine the easy
expandability of a 10Mb stackable hub system with the convenience and simplicity
of a small foot-print solution. Smaller than a paperback book, an ST80 unit is
easy to-install in an office, lab, support center, conference room, trade show,
or sales demo facility.
Stackable Personal Hubs can stack up to five high to support as many as 40
twisted-pair ports, yet act as a single-repeater unit. Each full-function ST80
hub has eight 10Mb RJ-45 ports plus one standard AUI port and an optional BNC or
fiber port for flexibility in connecting to network backbones and specialized
devices.
ST80 Stackable Personal Hubs can expand Ethernet connectivity in existing
workspaces and offices. An up-link port can connect the ST80 unit or stack to a
central network using an existing RJ-45 outlet to support additional PCs,
workstations, and other networked devices. When the up-link port is switched
off, the full 10 Mbps Ethernet capacity of the Magnum ST80 stack is available
for network activity within the local office or lab area.
Expanding an ST80 stack is easy. The units attach to each other using small
metal brackets that come with each unit. The inter- repeater-bus cable plugs in
on the side. Switches are then set to enable single-repeater stacked operation.
ST80 Stackable Personal Hubs can be located on any convenient desktop or shelf
in the workplace. The external power supply plugs into a nearby AC wall socket
or power strip.
ST80 Hubs are compatible with all networking software environments and support
full-length twisted-pair segment distances. Magnum ST80 Stackable Personal Hubs
and all other Magnum products are designed and manufactured in the USA and are
backed by a three-year warranty.

PACKAGING:
Enclosure: High-strength steel, suitable for vertical or horizontal
mounting
Dimensions: 6.75 in x 4.0 in x 1.0 in (17.1 cm x 10.1 cm x 2.5 cm)
Weight: 1.3 lb (600 gr)
Power Supply: 1.0 lb (455 gr)
Cooling method: Convection
SWITCHES:
Up-Link: Thumb-operated slide switch, converts RJ-45 port # 8 from
a regular (= position) user segment port to a crossover (X position)
up-link port for on-off connection to another hub.
Stack Enable: Manual slide switch, indicates the ST80 is used standalone
or as a base unit, or is used as additional unit in a stack.
Internal Termination Switch (ST80-B only): Allows BNC cable connection
without a tee connector and 50 ohm terminator, or requires
a tee when switched.
LED INDICATORS: PWR: Steady on when power applied
COL: Blinks yellow for a transmit collision
LINK/TX (Per Port): Steady on when there is proper connection and
power on both ends of the TP cable. Blinks as packets are transmitted
on the port.
POL/RX (Per Port): Blinks when port receives packets, steady on
when reverse polarity detected.
