2.2.1 Ports Speed
100Base-TX
All 100Base-TX ports come with auto-negotiation capability.
They automatically support 100Base-TX and 10Base-T
networks. Users only need to plug a working network device
into one of the 100Base-TX ports, then turn on the hub. The
port will automatically runs in 10Mbps, 20Mbps, 100Mbps or
200Mbps after the negotiation with the connected device.
2.2.2 Cabling
Fast Ethernet Switch 100Base-TX ports use RJ-45 sockets -similar to phone jacks -- for connection of unshielded
twisted-pair cable (UTP). The IEEE 802.3u Fast Ethernet
standard requires Category 5 UTP for 100Mbps
100Base-TX. 10Base-T networks can use Cat.3, 4, or 5 UTP
(see table A)

2.3.1 Power Connector
The Power Connector is designed to be used with the power
cord included in the product package. Attach the female end
of the cord to the power connector and the male end of the
cord to a grounded power outlet. The accepted power range
is from 100VAC to 240VAC, 50/60Hz.
Note:
The Switch is a power-required device, it means, the
Switch will not work until it is powered. If your networked
PCs will need to transmit data all the time, please consider
use an UPS (Uninterrupted Power Supply) for your
Switch. It will prevent you from network data loss.
In some area, installing a surge suppression device may
also help to protect your Switch from being damaged by
unregulated surge or current to the Switch or the power
adapter

CHAPTER 3 INSTALLATION
The Fast Ethernet Switch do NOT require software configuration. Users can immediately use any of the features of this
product simply by attaching the cables and turning on the
power.
To get the best use of these Fast Ethernet Switch models,
many things need to be considered first. See Section 4,
OPTIMIZING CONFIGURATION for details.
3.1 Rack-Mount Installation
Most users prefer to attach the power cord to the hub before
installation in a network rack. Do not plug the other end of the
cord into a power outlet until after the Switch is installed.
For mounting the Fast Ethernet Switch
attach the rack-mount brackets to the side of the hub with
screws. (Both brackets and screws are included in the product
package.) Slide the hub into the rack and align the holes in the
bracket with the corresponding holes in the network rack. Attach the bracket to the rack with the enclosed screws.
in a network rack, first
3.2 Desktop Installation
To locate the Fast Ethernet Switch models on a desktop, first
attach the four rubber feet to the bottom of the hub, one in each
corner. Place the hub on a clean, flat desk or table-top close to
a power outlet. Make sure there is no hindrance behind the fan
of the hub
Plug in all network connections and then turn the switch on via
plug in the power cord.

CHAPTER 4 OPTIMIZING
CONFIGURATION
4.1 Prior to Installation
Before installing the Fast Ethernet Switch models and connecting network devices, it is important to plan the new network
layout. Consider:
Dedicated Bandwidth:
high-traffic hardware can improve if they have their own
direct connection with dedicated 10 or 100Mbps bandwidth.
Full-Duplex:
from a Full Duplex connection and check that they
support it.
Fast Ethernet:
different rules for cable and distance. Make sure these
are followed.
Auto-Negotiation:
be easily swapped when the other end of the cable is
fixed to a port with auto-negotiation.
Determine which devices would benefit
100Base-TX and 100Base-FX have
File servers and other
Devices with different speeds may
4.2 Half- and Full-Duplex
The Fast Ethernet Switch supports both Half- and Full-Duplex
modes for 10Base-T and 100Base-TX. Half-Duplex mode is the
traditional data transfer mode: one station sends data while
other devices wait for the first to finish.
Full-Duplex is the simultaneous transmission and receiving of
data. It is only possible between two devices with a dedicated
link (e.g., switch-to-switch, switch-to-PC). Both of the devices
must be capable of, and set to, Full-Duplex
100Base-TX ports use auto-negotiation to detect and set the
line's operating mode.
- 9 -
4.3 Fast Ethernet
100Base-TX and 100Base-FX are called "Fast Ethernet." This
is because they use the Ethernet CSMA/CD access rules and
data packet structure, but data travels ten times faster
(100Mbps) than traditional 10Mbps Ethernet.
Below is a list of the cable types and connectors that supported
by Fast Ethernet
100Base-FX networks.

Cat.3, 4, 5 UTP RJ-45
In many cases, 10Base-T LANs can quickly and easily upgrade
to 100Base-TX networks.
4.4 Auto-Negotiation
The 100Base-TX ports on the Fast Ethernet Switch have
built-in "Auto-Negotiation". This technology automatically sets
the best possible bandwidth when a connection is established
with another network device (usually at Power On or Reset).
This is done by detect the mode and speed at the second device is capable of. The 100Base-TX devices can connect with
the 100Base-TX port in either Half- or Full-Duplex mode.
If attached device is: 100Base-TX port will set to:
100Mbps, no auto-negotiation 100Mbps
(100Base-TX, Half-Duplex)
100Mbps, with auto-negotiation 200Mbps
(100Base-TX, Full-Duplex)
10Mbps, no auto-negotiation 10Mbps
(10Base-T, Half-Duplex)
10Mbps, with auto-negotiation 20Mbps
(10Base-T, Full-Duplex)

4.5 MAC Address Table
This 6-byte ID is called the MAC (Media Access Control) Address. Every Ethernet data packet includes both source and
destination addresses.
These Fast Ethernet Switch models can automatically learn
and store up to 8K MAC addresses. The MAC address table is
volatile: it disappears when the switch is powered off or reset.
Note: When the network needs reconfiguration, we
recommend turning off the power first. After all
nodes have been moved, power on the switch to
rebuild the internal MAC address table.

4.6 Sample Application
The optimal application for the Fast Ethernet Switch, no matter
with the extension module or not, is as a "big pipe" backbone
interconnecting file servers with bandwidth-hungry workgroups,
departments, and offices.
In the figure, the first FNSW-1601(or FNSW-2401) links to another hub‘s Uplink (MDI-II) port, some ports connect to
100Mbps Workstations, and attached to file servers at
200Mbps.

CHAPTER 5 TROUBLESHOOTING
Symptom Link LED does not lit after cable is connected to
the port.
Checkpoint Verify that the other end of the cable is connected
to a device that is powered on and on-line.
For UTP cable connection to another hub, verify
that only one end of the cable is connected to a
“MDI-II” Uplink port.
Symptom 100Base-TX port Link LED is lit, Collision LED is
blinking, but traffic is irregular.
Checkpoint Check that the attached device is not set to
dedicated full-duplex. (Some devices use a
physical or software switch to change duplex
modes. Auto-negotiation may not recognize this
type of full-duplex setting.
ALWAYS CHECK THAT THE CABLE, LINK DISTANCES,
AND OVERALL NETWORK DIAMETER ARE WITHIN SPEC.
