Product User Guide
Introduction
This compact Tyco Electronics/AMPNetconnect auto-negotiating
Ethernet workgroup smart switch enables SOHO users and small
size workgroups to have high speed, low latency LAN connections
to the main network using a fibre link.
The automatic sensing of the connected 10/100Mbit/s data rate
and the detection of either a switch/hub or PC connected to the
Ethernet copper ports eliminates the need for any Ethernet crossover cables and greatly simplifies installation.

Ports
RJ-45 Ports. These Ethernet RJ-45 ports support both
shielded and unshielded cabling systems. Each port autonegotiates the 10/100Mbit/s network speed and autodetects the connected device type which eliminates the
need for cross-over cables.
Fibre Port. The switch has a fibre uplink port that can be
connected to 100Base-FX devices. Different optical
connector formats are available (ST/SC/MT-RJ) together
with singlemode and multimode fibres.
Console Port. This port enables the administrator to
change switch settings such as port values, VLANs etc.
AC Power Connector This connector accepts any
standard IEC 320 style power connector.

Installation
Copper and Fiber Cabling Guidelines
1. The RJ-45 ports can be connected to unshielded twisted pair
(UTP) or shielded twisted pair (STP) cabling systems compliant
with the IEEE 802.3u 100Base TX standard for Category 5. The
cable between the switch and the link partner device (router,
hub, workstation, etc.) must be less than 100 metres long.
2. The switch auto-detects the type of connected device (PC or
hub) and automatically configures the RJ-45 port to avoid the
need for an Ethernet cross-over cable.
3. The fibre link must use either 50 or 62.5/125 micron multi-mode
or 9/125 micron singlemode cable (dependant on model). You
can link two devices over a distance of up to 2km for multimode
or 15km on singlemode. See optical budget specifications.
4. The console port is an RS232 port and should not be used for
cable distances greater than 20 metres. Use the supplied data
cable wherever possible.
Desktop Installation
1. Fit the self-adhesive rubber feet to the underside of the switch.
2. Locate the switch in a clean, flat and safe position that has easy
access to AC power. Ensure that there is sufficient clearance
around the switch to enable air circulation.

Completing The Installation
When the switch has been installed as specified above, then the
unit can be configured as detailed below:-
1. Connect the AC power cable to the switch. The green Power
LED on the front panel of the switch should light.
2. Connect the Cat. 5/5e twisted pair cables from the network
partner devices to the RJ-45 ports on the switch. When a
network connection is obtained, the green LK/ACT LED
associated with the port will light.
3. Connect the fibre link to the partner device (media converter,
fibre NIC card or fibre switch etc). Verify that the green LK/ACT
LED for the fibre port is lit which indicates that the optical link is
valid.
4. If advanced modes such as port configuration or port-based
VLANs are needed, then use the console port to configure the
switch. See the console port instructions on page 7.
5. If legacy devices that do not support auto-negotiation are
connected to the RJ-45 ports, then it may be necessary to
program the switch to match the speed and duplex modes of
the partner devices. See page 9
6. Note that auto-negotiation can take up to 30 seconds to
complete depending on the partner device.

Configuring The Console Port
The switch has a console port on the rear panel that can be used
to provide simple control and configuration of the unit. The
following port controls are available:-
• Port Data Rate
• Port Duplex Mode
• Port Based VLAN Assignment
A PC can be used to communicate with the switch using the
console port. A terminal emulation program such as Windows
Terminal or HyperTerminal is configured to the following settings:-
• Com Port 1 or 2
• Speed = 9600
• Data Bits = 8
• Parity = None
• Stop Bits = 1
• Flow Control = None
Figure 3 - Console Port Settings
Connect the PC RS232 serial port to the Console port using the
data cable supplied with the switch. Enter any key and the screen
should now show the top-level console display.

8 Port Ethernet Smart Switch With Fibre Uplink
This entry screen is
displayed when the
connection is first
established with the
switch. Select the
required option.
Note that the options
3 and 4 are
immediate and do
not have any
confirmation steps.
Figure 4 - Entry Screen
The port setting
screen is selected
by entering 1 in the
entry menu.
The screen then
shows the current
state of all the
switch ports similar
to the image to the
right.
To change a port
setting, enter the
port number (1..9)
and a new screen is
displayed similar to
Figure 6 on the next
page.
Figure 5 – Port Setting Screen - 1
Tyco Electronics Page 8
8 Port Ethernet Smart Switch With Fibre Uplink
This screen enables
the port speed and
duplex mode to be
controlled.
The default is autonegotiation which is
the best method for
most new networks.
However, some
legacy systems may
need to use fixed
duplex and speeds,
so these can be
applied on the switch
using this menu.
Select the option 1..5
to change port
settings or select 6 to
return to the main
menu.
Figure 6 - Port Configuration - 2
Simple port based VLANs can be created by selecting option 2
from the entry menu. There are 2 steps to create VLANs. First
draw a map that shows a matrix of ports and VLANs.
Then select the port
and the required
VLAN ID (1..7). To
Figure 7 - Port VLAN Configuration
add the port to the
VLAN, enter option 1
and then enter option
3 to save the setting.
Repeat this for all
required VLAN and
port combinations.
Note that the switch
resets each time the
VLAN state is viewed.
This is normal.

Trouble Shooting
Power
1. Verify that the AC power is present and that the external fusing
is correct and compliant with national requirements. The green
Power LED should be lit to indicate that the switch is powered
correctly.
Data Problems
1. Ensure that the Ethernet partner device (switch, router, NIC etc)
connected to the RJ-45 UTP port of the switch is set for autonegotiation. If this Ethernet partner device does not support
auto-negotiation, then you need to program that device to
operate at 100Mbit/s half duplex or 10Mbit/s half duplex or
program this switch using the console port.
2. If the switch and the partner device cannot auto-negotiate then
both units automatically revert to the lower level of half-duplex
operation. This issue is common to all auto-negotiating Ethernet
devices and the symptoms of incorrect negotiation include data
errors and fragmented packets.
3. Auto-negotiation can take up to 30 seconds to complete
depending on the partner device.
4. Ensure that the switch is not overheating due to obstructed
airflow around the side vents.
5. Select the proper fibre cable for your network. See page 4 for
the supported cable types and installation settings.
6. Ensure that the optical loss budget of the fibre uplink is within
the limits specified on page 11. Note that optical patch cables
and other joints and splices can introduce additional optical
losses that reduce the working distance of the fibre link.
7. Restore factory settings by selecting option 3 on the main menu
of the console port.
Console Problems
1. Verify that the PC has been set up with the correct serial link
settings as detailed on page 7.
2. Ensure that the serial data cable supplied with the switch is
used.
If you still have problems and need further advice, please see
Technical Support section on page 2 to obtain more information.

Fibre Uplink Port Specifications
The switch has a 100Base-FX optical fibre uplink port that
operates at the 1310nm optical wavelength for both the multimode
and singlemode models.
The fibre size used for multimode links is 50/125 or 62/125 micron.
The fibre size used for singlemode links is 8/125 or 9/125 micron.
The maximum distance between any two fibre optic devices is
determined by a number of factors including optical link loss, the
type and number of patch cords and joints in the link, the launch
power of the transmitter and the sensitivity of the receiver. These
variables make calculating the maximum working distance
between two converters quite difficult and so it is best to design
networks using optical loss budgets rather than using just working
distance.
