following list to look up specific subjects.
Overview of your AsantéHub
1012 and Quick Start
Installation Procedures
See Chapter 1, "Quick Start." The first few
pages provide a quick, visual overview of hub
physical features
The rest of the chapter describes installation
of a one-hub departmental network, with
optional connection to a thin Ethernet
backbone.

Specifications."
Cable specifications See Appendix C, "Pinouts and Cable
Specifications."
Terminology used in this
manual See the "Glossary."

vii
Other Manuals in This Product Family
If you purchased the Simple Network Management Protocol (SNMP) option, you
need to perform some software configuration before you can communicate with
the hub over a TCP/IP network; see the manual, AsantéView Users' Guide for
Windows, In-Band. SNMP card installation instructions are included in the option
package.
To run the out-of-band version of AsantéView, see the manual, AsantéView
Users' Guide for Windows, Out-of-Band.
To run the Macintosh version of AsantéView, see the manuals,AsantéView
Users' Guide for Macintosh, Out-of-Band ( or AsantéView Users' Guide for
Macintosh, In-Band ).
Compatibility
The AsantéHub is compatible with all 10BaseT-compliant twisted-pair products,
whether or not they are manufactured by Asanté. If you are using the AsantéHub
with a pre-10BaseT product, you may disable Link Integrity on a port-by-port
basis from AsantéView.
Other Asanté 10BaseT Networking Products
To connect network devices to the AsantéHub, you need a 10BaseT-compatible
internal or external adapter for each machine. Asanté Technologies provides a
complete line of network adapter products. All Asanté products support the latest
IEEE specifications.

Product Overview
The AsantéHub 1012™ is a compact, powerful LAN hub that lets you create
high-speed Ethernet networks over ordinary, unshielded twisted-pair (UTP)
telephone wire. AsantéView network management software lets you manage the
AsantéHub 1012 network remotely, with graphical software that is intuitively easy
to use.
The AsantéHub 1012 offers complete flexibility in LAN wiring. Network devices
can be connected by way of twelve front panel 10BaseT ports, or to a punch-
down block using the rear panel Telco port. Hubs can be networked using the
3-In-1 Uplink with RJ45, BNC, and AUI ports. These ports support twisted-pair
and thin Ethernet wiring , as well as thick or fiber optic connections with the
appropriate transceiver. The 3-In-1 Uplink supports redundant physical links and
link auto-sensing.
AMS (AsantéView Management System) Link (RJ-45) ports provide dedicated
out-of-band network management daisy-chained connections to other hubs or to
a network management station located at the end of the chain. An RS-232 serial
port provides connection for a network management station, terminal, or modem
(for remote dial-up).
The AsantéHub 1012 offers comprehensive LED indicators for network status,
including per-port link/receive status, automatic and manual partitioning, network
utilization, and packet collision ratios. These indicators are reproduced in
graphical form in AsantéView. There are also warning indicators to monitor
troubleshooting for the AsantéHub.
In addition, the AsantéHub 1012 offers comprehensive, centralized LAN
management through AsantéView network management software. AsantéView
runs as an application on Macintosh computers or on PCs under Windows.
If you purchased the optional SNMP daughter board, AsantéView supports
network management based on the Simple Network Management Protocol
(SNMP). With this option, AsantéView can be run as part of a centralized
SNMP-based network management console, and information can be passed to a
third-party SNMP manager.

xi
Features
AsantéHub 1012 offers outstanding technical features in a compact, modern
design:
•Twelve 10BaseT Ports — Up to twelve network devices can
be connected to a single AsantéHub (thirteen, in a standalone
configuration).
•Auto-Sensing Network Ports — Auto-sensing network ports
with AUI, BNC and RJ-45 connectors support thick, thin or
10BaseT wiring.
•Redundant Link Support — The 3-In-1 Uplink can be
configured for redundant network links, for quick re-
establishment of network services in the event of a backbone
failure.
•110/220 Volt Auto-Switch Power Supply — Installation at
foreign and domestic sites requires no special switch or jumper
settings.
•Dedicated Out-of-Band Network Management — AMS
(AsantéView Management System) Links can connect up to
eight hubs and span up to 2000 feet. The network
management station can be connected as a device on the
AMS Link, or directly to the RS-232 port on the hub. The RS-
232 port supports a local network management station,
terminal for local hub configuration, or modem for remote dial-
up.
•Fault-Isolated Network Management — Network
management and communications are isolated in hardware, so
that the status of the network management link does not affect
normal network services.
•In-Band Network Management — Optional plug-in SNMP
daughter-board supports SNMP-based network management;
completely software-configurable.
•Flexible placement — The AsantéHub's compact, modern
design allows it to be placed on a desktop, or in a telephone
closet via wall mounts or rack mounts. Rack and wall
mounting hardware is included with each hub.

xii
•Detailed Front Panel Indicators — The LED indicators of the
AsantéHub indicate:
* Functionality of CPU and SNMP option
* AsantéView message status
* Out-of-band and in-band link functionality
* Port partition status (automatic or operator-
commanded) for link and device ports
* Port link status and receive activity for link and device
ports
* Presence of the following network errors: late
collisions, misaligned packets/CRC errors,
runt/fragmented packets, short event/missing SFDs
* Hub bandwidth utilization
* Collision ratio
•Downloadable Hub Software Upgrades — Software
upgrades can be downloaded from the network management
station or a designated server.
•Asanté Reliability and Performance — the quality, reliability
and performance you have come to expect from the maker of
the award-winning Asanté networking products.
AsantéView
AsantéView LAN management software provides a graphical interface that offers
comprehensive network analysis and control. AsantéView:
• Locates and identifies network devices automatically
• Provides configuration status at the hub, port, and card levels
• Displays hub status in a detailed graphical view of the front
and rear panels, with an active LED display
• Provides port-by-port control of transmission options such as
port partitioning, link integrity testing, polarity correction, jabber
control, noise threshold reduction, and primary uplink
selection, all from a single window

xiii
• Monitors network performance and displays comprehensive
statistics in three easy-to-read formats: tables, line graphs, and
bar charts
• Automatically responds to threshold violations by generating
traps, partitioning ports, and/or paging for assistance
• Protects network security with bi-level password structure
• Stores multiple map files for historical records or hierarchical
divisions of network management responsibilities.
For more information about AsantéView, see the AsantéView manual for your
version of AsantéView.
