GarrettCom 10Mb H50 H40A H80A H90A Personal Hubs


• Expands the number of 10Mb RJ-45 ports in a multi-system office

• Acts as a miniature fullfunction Ethernet hub with four to nine 10BASET ports, one of which is an up-link port with an on/ off switch

• Supports any combination of PCs, Macs, UNIX workstations, portables, servers, networked printers, and other devices

• Is compatible with all networking software environments

• Has a durable metal enclosure, external power supply for either 115 or 230 volt environments


Magnum Personal Hubs® are an inexpensive solution for users that need an easy-to-install 10Mb Ethernet network for a small office, lab, conference room, trade show, sales demo, or home computer installation.

Personal Hubs are full-function repeaters that can operate as stand-alone hubs, providing networking services for four to nine devices. Personal Hubs can also expand local 10BASE-T Ethernet connectivity for existing personal workspaces and offices. An up-link port can connect the Personal Hub to a central network using an existing RJ-45 outlet, providing four to eight twisted-pair ports to support additional PCs, workstations, and other networked devices.

Even networking novices can expand their network access from one to multiple ports in only a few minutes, without modification to building wiring. They simply plug their existing networked office device into one of the Personal Hub’s front ports. The Personal Hub’s up-link port connects to the existing network outlet.

The additional Personal Hub ports are available for expansion devices. When the up-link port is off, the full 10 Mbps Ethernet capacity of the Personal Hub is available for network activity within the personal workspace or local office. A Personal Hub is easy to set up and monitor. The LED indicators show at a glance whether the Hub and all attached segments are operating properly. Smaller than a paperback book, a Personal Hub can be located on a desktop or Velcro®-mounted vertically on an office wall or the side of a desk or cabinet.

The external power supply plugs into a nearby AC wall socket or power strip. Personal Hubs are compatible with all networking software environments and support full-length twisted-pair segment distances. The Magnum 10Mb Personal Hubs and all Magnum products are designed and manufactured in the USA and are backed by a three-year warranty.


PERFORMANCE: Data Rate: 10 Mbits / second RPM Partitioning: Enforced after 32 consecutive collisions RPM Reconnect: Occurs after 512 bits of error-free transmission

MAXIMUM STANDARD ETHERNET LENGTHS: DTE (AUI drop cable): 50m 10BASE-T (twisted pair): 100m 10BASE2 ThinNet: 185m 10BASE5 ThickNet: 500m 10BASE-FL Multi-mode Fiber Optic 2.0km Single-mode Fiber Optic 10.0 km

NETWORK STANDARDS: Ethernet V1.0/V2.0, IEEE 802.3; 10BASE-T, 10BASE2, 10BASE5, DTE, 10BASE-FL

OPERATING ENVIRONMENT: Ambient Temperature: 32° to 120°F (0° to 50°C) Storage: -20°C to 60° C Ambient relative humidity: 5% to 95% (non-condensing)

POWER SUPPLY (EXTERNAL): Power Input Voltage: 95-125 vac at 60 Hz for “-d” Models, 200 - 250 vac at 50 Hz for “-i” Models that have IEC power cable connection. Power Consumption: H50 and H40A: 6 watts max., H90 and H80A: 10 watts max.

SWITCHES: UP-LINK: MDI-X (Media Dependent Interface - Crossover) thumb operated slide switch, converts one RJ-45 port from a regular (= position) user segment port to a crossover (X position) up-link port for on/off connection to a central hub or another cascaded hub.

LED INDICATORS: PWR: Steady on when power applied RX (Per Port): Blinks when there is activity on the port LINK (Per Port): Steady on when there is proper connection on both ends of the cable segment

CONNECTORS H50: Four front and one rear RJ-45, female shielded type H40A: Four front RJ-45s, female shielded type, one rear AUI H90: Eight front and one rear RJ-45s, female shielded type H80A: Eight front RJ-45s, female shielded type, one rear AUI 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-tousers twisted-pair wiring: pin 1 = receive+, 2 = receive-, 3 = transmit+, 6 = transmit-, other pins not used. The switched RJ-45 port 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.
