INTRODUCTION
This chapter describes the features of the Switch and some
background information about Ethernet/Fast
Features
The Switch was designed for easy installation and high
performance in an environment where traffic on the network
and the number of user increase continuously.
The Switch with its small, compact size was specifically
designed for small to middle workgroups. This Switch can be
installed where space is limited; moreover, they provide
immediate access to a rapidly growing network through a wide
range of user-reliable functions.
The Switch is ideal for deployment with multiple high-speed
servers for shared bandwidth 10Mbps or 100Mbps workgroups.
With the highest bandwidth 200Mbps (100Mbps full-duplex
mode), any port can provide workstations with a congestion-
free data pipe for simultaneous access to the server.
The Switch is expandable by cascading two or more switches
together. As all ports support 200Mbps, the Switch can be
cascaded from any port and to any number of switches.
The Switch is a perfect choice for site planning to upgrade to
Fast Ethernet in the future. Ethernet workgroups can connect
to the Switch now, and change adapters and hubs anytime later
without needing to change the Switches or reconfigure the
network.
The Switch combine dynamic memory allocation with store-
and-forward switching to ensure that the buffer is effectively
allocated for each port, while controlling the data flow between
4
the transmit and receive nodes to guarantee against all possible
packet loss.
The Switch is a managed 10/100 Fast Ethernet Switch that
offers solutions in accelerating small Ethernet workgroup
bandwidth. Other key features are:
Auto-MDI function supports automatic MDI/MDIX crossover
detection function gives true ‘plug and play’ capability without
the need of confusing crossover cables or crossover ports.
Store and forward switching scheme capability. As the result
of complete frame checking and error frame filtering, this
scheme prevents error packages from transmitting among
segments.
NWay Auto-negotiation for any port. This allows for auto-
sensing of speed (10/100Mbps) thereby providing you with
automatic and flexible solutions in your network connections.
Flow control for any port. This minimizes dropped packets by
sending out collision signals when the port’s receiving buffer is
full. Note that flow control is only available in half duplex
mode.
Data filtering/forwarding rate is wire-speed for 10Mbps and
100Mbps speed.
4K MAC address entry table per device with self-learning for
the Switch.
128KBytes RAM buffer per device for the Switch.

UNPACKING AND SETUP
This chapter provides unpacking and setup information for the
Switches.
Unpacking
Open the shipping cartons of the Switch and carefully unpacks
its contents. The carton should contain the following items:
One 8-port 10/100M NWay Ethernet Switch
One external power adapter
This User’s Guide
If any item is found missing or damaged, please contact your
local reseller for replacement.
Setup
The setup of the Switch can be performed using the following
steps:
The surface must support at least 1.5 Kg for the Switch.
The power outlet should be within 1.82 meters (6 feet) of the
Switch.
Visually inspect the DC power jack and make sure that it is
fully secured to the power adapter.
Make sure that there is proper heat dissipation from and
adequate ventilation around the Switch. Do not place heavy
objects on the Switch.
