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.

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.

QOS Control

The switch allows basic prioritization of packets through the switch
using a central dual queue system. Each port can be programmed
to forward all traffic at either low priority or high priority. These
priorities are assigned on a per-port basis and are not dependent
on the QoS or ToS bits within the packet. A typical application of
this would be to allow high priority VoIP traffic on a port to be
forwarded by the switch in preference to traffic from a standard PC
connected on another port.

Figure 11 - QoS Control Screen

This QoS screen is selected from the main menu using the Q
option.

Priority Setting

The priority level can map the selected port to use either the high
or low priority queue. This control is applied on a per-port basis. To
configure the priority setting, select P from the QOS Control menu.
The screen below will be displayed.

Figure 12 - QoS Priority menu

24 Port Ethernet Switch With Optional Fiber Port

Tyco Electronics Page 13

1. To set a port at high priority, enter the “+” key and then the port

number followed by the <CR> or enter key. The screen will
show the port number in square brackets. Each time a port is
set at high priority, the list in the brackets will be modified to
show the ports in high priority mode. If one or more ports is in
the high priority mode, then the QoS Control menu will show
QoS On.

2. To set a port at low priority, enter the “-” key and then the port

number followed by the <CR> or enter key. This command will
only work with ports that are high priority (listed within the
square brackets). If all ports are in the low priority mode, then
the QoS Control menu will show QoS Off.

3. To set all ports at high priority use the “+” key and then “A”

followed by the <CR> or enter key. To set all the ports at low
priority, use the “–“ key and then “A” followed by the <CR> or
enter key.

4. Save the QoS settings using the “S” key.

5. Exit to the QoS Control menu using the “Q” key.

Pause Control

When the priority mode is active, then packets can be delayed
from being processed by use of the pause control. This pause
control is only relevant when operating in the full duplex mode. To
enable or disable the pause control on a port, select the option C in
the QoS Control menu and then add or delete ports using the
same “+” and “–“ key methods as described above.

When the pause control on a port is enabled, then it will be shown
in the List QoS setting map with the letter E. When the pause
control is disabled, it will be shown in the List QoS screen with the
letter D.

Note that for pause control to function properly, both ends of the
link must be capable of using pause control. Some legacy units do
not support pause control.

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.

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. If this
is not possible, then the switch can be programmed to apply the
required speed and duplex modes to match the legacy partner
equipment.

2. If the switch and the partner device cannot auto-negotiate then

the units automatically revert to the lower level of half-duplex
operation. This issue is common to all auto-negotiating Ethernet
devices and 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.

Optional Fiber Uplink Module

1. Select the proper fiber cable for your network. The multi-mode

module must use multi-mode fiber cable and the single-mode
module must use single-mode fiber cable. See page 4 for the
supported cable types and installation settings.

2. Ensure that the optical loss budget of the fiber uplink is within

the limits specified on page 18. Note that optical patch cables
and other joints and splices can introduce additional optical
losses that reduce the working distance of the fiber link.

If you still have problems and need further advice, please see
Technical Support section on page 2 for more information.
