Ports
Figure 1 - Switch with optional fiber module fitted
RJ-45 Ports. These Ethernet RJ-45 ports support both
shielded and unshielded cabling systems. The port autonegotiates the 10/100Mbit/s network speed or can be
forced by the console management interface into either
10Mbit/s or 100Mbit/s at either full-duplex or half-duplex.
Each port supports Auto-MDI/MDI-X which allows either
straight through or cross-over cables to be used.
100FX Fiber Port. This optional, field installable plug-in
module provides the fiber link to the distant media
converter, NIC card or Ethernet switch. The port operates
in either full duplex or half duplex modes depending on the
setting of DIP switch on the panel of the plug-in module.
Modules with SC, ST and MT-RJ fiber optic connectors are
available. See page 6 for order codes.
Console Port. A PC or other RS232 terminal is connected
to this port to enable detailed management of the switch.
See the documentation on the web site for full information.
Rear Panel
The rear panel contains the 110/240v AC 50/60Hz power socket
and power switch. Note that the fusing is external to the switch. To
disconnect power, remove the plug.

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 fiber link on the optional multi-mode module must use
either 50 or 62.5/125 micron multi-mode fiber cable. You can
link two devices over a distance of up to 2 kilometres.
3. The fiber link on the optional single-mode module must use
8/125 or 9/125 micron single-mode fiber cable. You can link two
devices over a distance of up to 15 kilometres in full duplex
mode or 412 metres (1,352 ft.) in half-duplex.
4. The console port is an RS232 port and should not be used for
cable distances greater than 20 metres.
Desktop Installation
1. 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.
2. Fit the self-adhesive rubber feet to the underside of the switch.
Installing The Switch Into a 19” Rack
1. Identify the required locations and ensure that there is at least
10cm clearance at the front and rear of the switch to allow
cables to be accommodated.
2. Fit the supplied rackmount bracket on both side plates of the
switch using a screwdriver.
3. Locate the switch into the rack and align the holes in the
brackets with holes in the rack vertical strips. Secure the switch
using the supplied bolts.
Installing The Optional Fiber Uplink Module
1. Remove AC power from the switch.
2. Remove the two screws securing the front panel blanking plate.
3. Observe anti-static handling precautions and carefully fit the
plug-in module into the switch and secure it using the thumb
screws.

Completing The Installation
When the switch has been installed as specified above, then the
unit can be configured as detailed below:-
1. Apply AC power to the switch. The green Power LED on the
front panel should light.
2. Connect the Cat. 5/5e twisted pair cables from the network
partner devices to the RJ-45 ports on the front panel of the
switch. When a connection is obtained, the green LK/ACT LED
associated with the port will light.
3. If the fiber uplink is used, then connect the fiber link to the
partner device (media converter, fiber NIC card or fiber switch
etc). Ensure that the fiber uplink is set in the correct duplex
mode (default = Full Duplex) using the front panel switch on the
module. Verify that the green Link LED on the fiber module is lit
which indicates that the optical link is valid.
4. If advanced modes such as port-based VLANs are needed,
then use the console port to configure the switch.
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.
6. Note that auto-negotiation can take up to 30 seconds to
complete depending on the partner device.

Optional Fiber Uplink Port
This switch can support one plug-in optical port that is located on
slides in the front panel.
Figure 2 - Plug-in SC option module
The option module is installed as described on page 4. The only
configuration needed is the Full/Half duplex switch on the front
panel. The default setting is Full and this will work for most
applications.
The following plug-in fiber modules are available as field installable
accessories for this switch:-
Product Part Number
Module with SC multimode connectors 0-1591050-0
Module with ST multimode connectors 0-1591052-0
Module with MT-RJ multimode connector 0-1591054-0
Module with SC singlemode connectors 0-1591056-0
Table 1 - Uplink Option Ports
The optional modules operate at the 1310nm optical wavelength.
The fiber size used for multimode links is 50/125 or 62/125 micron
and the fiber size used for singlemode links is 8/125 or 9/125
micron.
Optical Link Calculations
The maximum distance between any two fiber 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 units quite difficult and so it is best to design networks
using optical loss budgets rather than using just working distance.
