n
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.
Port speed adjustment is also available through console port.
n
100Base-FX
The port 16 can be a 100Base-FX fiber-optic port as the
extension module installed (rear) At the mean time, the RJ45 port of #16 will being disabled. The Half-/Full-Duplex is
selectable by the DIP-switch on the module. Please refer to
the installation guide of the extension module for more.
2.2.2 Cabling
NOVASwitch 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 below)

for more.
2.2.4 Status LEDs
One green LED to show power On/Off is on the front panel, and one
“Module Installed” LED indicator to indicate the rear open slot is
installed with a fiber-optic module. Also, each port has three status
LED indicators, as shown below.

2.3.1 Extension Slot
The Switch port #16 can be a 100Base-FX switching port as the
extension module installed. As the module installed, the port#16 on
the front panel will be disabled.
Please refer to the Installation Guide of the module for the detailed
installation and settings.
NOTE: While powering on, The Switch detects the DIP-
switch status of the module, then shown on the
front panel LED indicators
2.3.2 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.
2.3.3 Fan
All computing and communications devices work best when not
overheated. Please keep the fan area clear so that the cooling
function is not impaired.

2.3.4 RS-232 Console
The RS-232 console helps to manage the Switch. Please use
the cable with the package. Attach one end to the switch and
the other to your PC’s COM1 or COM2. Then startup your
console program like Windows Hyper Terminal, or ProCOMM
with parameter: 19200, n, 8, 1. Please refer to Chapter 4,
Console management for more.

3. INSTALLATION
The 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. However, the
Console port will helps to have more setting to your swtiches.
To get the best use of the Switch, many things need to be
considered first. See Chapter 5 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 hub is installed.
For mounting the Switch in a network rack, first 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.
3.2 Desktop Installation
To locate the Switch 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, then turn the switch on via plug
in the power cord.
FNSW-1600S User’s Guide

3.3 Power notes:
1. The device is a power-required device, it means, it will not
work till it is powered. If your networks should active all the
time, please consider use an UPS (Uninterrupted Power
Supply) for your device. It will prevent you from network data
loss or network downtime.
2.In some area, installing a surge suppression device may also
help to protect your hub from being damaged by unregulated
surge or current to the Switch or the power adapter.

5. OPTIMIZING CONFIGURATION
5.1 Prior to Installation
Before installing the Switch and connecting network devices, it
is important to plan the new network layout. Consider:
• Dedicated Bandwidth: File servers and other high-traffic
hardware can improve if they have their own direct connection
with dedicated 10 or 100Mbps bandwidth.
• Full-Duplex: Determine which devices would benefit from a
Full Duplex connection and check that they support it.
• Fast Ethernet: 100Base-TX and 100Base-FX have different
rules for cable and distance. Make sure these are followed.
• Auto-Negotiation: Devices with different speeds may be
easily swapped when the other end of the cable is fixed to a port
with auto-negotiation.
• Crossover Uplink: Another hub can be attached to Switch
using UTP Crossover function.
5.2 Half- and Full-Duplex
The Switch support both Half- and Full-Duplex modes for
10Base-T, 100Base-TX, and 100Base-FX. 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
The 100Base-FX port set Half- or Full-Duplex mode through
module's DIP-switch. 100Base-TX ports use auto-negotiation to
detect and set the line's operating mode.
FNSW-1600S User’s Guide
25
5.3 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 Switch for 10Base-T, 100Base-TX, and 100Base-FX
networks.

Table C: Cables & Connectors Supported by FNSW-1600S
In many cases, 10Base-T LANs can quickly and easily upgrade
to 100Base-TX networks. Also, 100Base-FX will become more
popular due to its longer range. Table lists the maximum Fast
Ethernet connection distances.

5.4 Auto-Negotiation
The 100Base-TX ports on the Switch have built-in "AutoNegotiation". 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)
5.5 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.
The Switch 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.
FNSW-1600S User’s Guide

5.6 Sample Application
The optimal application for the 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-1600S links to another switch‘s
Uplink (MDI-II) port, some ports connect to 100Mbps
Workstations, and attached to file servers at 200Mbps. This
example highlight the extra distance provided by 100Base-FX
fiber-optic, using the Port #16 of FNSW-1600S with the rear
module installed.
