DIP Switch Settings
Reserved (Switch 1)
Auto Negotiation (Switch 2)
Switch Position Mode
Up (default) On
Down Off
Auto: In this mode of operation the media converter will negotiate
Ethernet parameters on the copper connection. This will ensure
the most optimal connection parameters will be in effect. If the
copper link partner does not support Auto negotiation, the SR-100
will default to 100 Mbps and Half Duplex mode.
Off: Auto Negotiation should only be turned off, if the copper link
partner does not support Auto Negotiation.
When the Auto Negotiation switch is set to the Off position, the
media converter will operate at 100 Mbps and Full Duplex mode.
Smart Link Pass-Through (Switch 3)
Switch Position Mode
Up (default) Enable
Down Disable
Enable: In this mode, the link state on one connection is directly
reflected through the media converter to the other connection. If
link is lost on one of the connections, then the other link will be
brought down by the media converter.
If the installation has a media converter on both ends of the fiber
link and both are setup for Link Pass-Through, then a loss of
copper link on the far end device will propagate through both
media converters and will result in a loss of copper link at the near
end device. This would, therefore, resemble a direct copper
connection.
Disable: In this mode, the links on the fiber and copper sides can
be brought up and down independently of each other. A loss of
link on either the fiber ports or copper ports can take place without
affecting the other connection.

Perle SR-100 Fast Ethernet Media Converter Installation Guide 9
Far End Fault (Switch 4)
Switch Position Mode
Up (default) Enabled
Down Disabled
Enabled: If the media converter detects a loss of fiber signal on
the fiber receiver, it will immediately send a FEF on the fiber link.
This, in effect, notifies the fiber link partner that an error condition
exists on the fiber connection.
If the remote media converter is set up for Far End Fault (FEF)
and the local media converter is set up with Link Pass-Through, a
loss of fiber link on either the transmit or receive line will be
passed through to the local copper connection thus notifying the
connected device.
If the media converter has been set to Link Pass-Through mode,
the effect will be the same as FEF, since the link loss on the fiber
receiver will bring down the copper link, which will in turn cause
the transmit fiber link to be brought down.
NOTE: This switch needs to be set to either generate or detect
the FEF signal.
Disabled: The media converter will not monitor for or generate Far
End Fault.
The following diagram is an illustration of the operation of this
feature.
(A) – Remote Media Converter setup for Far End Fault
Enabled, Auto Negotiation – OFF and Link Mode – Standard.
(B) – Local Media Converter setup for Link Pass-Through and
Auto Negotiation - OFF
(A) loses fiber connection on its receiver
(A) sends an FEF
(B) detects loss of link in its fiber receiver
(B) drops link on copper connection through Link Pass-Through
(A) Link on copper connection is not affected.

Reserved (Switch 5)
Pause (Switch 6)
Switch Position Mode
Up (default) Auto
Down Half
Auto: When Auto Negotiation has been set to Auto (SW 2), the
media converter will use this setting for its Ethernet parameter
negotiation on the copper connection.
Half: The media converter will not negotiate support for the Pause
feature.
NOTE: The media converter will not act on, or generate any
Ethernet Pause messages, but will pass them through to the end
device. This switch setting is provided so that the attached device
(near end) can negotiate its Ethernet parameters as if it was
negotiating directly with the far end device. The Pause switch
setting on the media converter should match the capabilities of the
far end device.
Loopback (Switch 7)
Switch Position Mode
Up (default) Disabled
Down Enabled
Disabled: The loopback feature is disabled. This is the normal
position for regular operation. The switch must be set to this
position for data to pass through the media converter.
Enabled: This is a test mode. All data received on the receive
(RX) fiber connection is looped back to the transmit (TX) fiber
connection. The state of the copper is not relevant and no data or
link status is passed through to the copper side.
Reserved (Switch 8)

Installing the SFP Fiber Module
The SR-100-SFP requires an SFP fiber module.
1. Locate your fiber module, and then insert the module into the
transceiver opening.
2. Ensure the SFP module is properly seated.
3. The SFP module may be inserted before or after applying
power to the media converter.
4. Proceed with cable connections.
Installing the Duplex Fiber Cable
•Locate a 100Base-X compliant duplex (2 strands) fiber cable
with male connections.
•Connect the fiber cables from one media converter to the other
media converter/switch/fiber device ensuring that the RX and TX
are reversed at the opposite end.
Installing the Simplex Fiber Cable
Locate a 100Base-X compliant simplex (1 strand) fiber cable with
male connections.
•Connect the fiber cable from one media converter to the other
media converter/switch/fiber device.
Installing the Copper Cable
•Locate 100Base-TX compliant copper cables with male, RJ45
connectors installed at both ends.
•Connect the RJ45 cable between the Perle media converter and
the device.
Note: The Perle media converter supports Auto-MDI-X, either a
straight-through or cross over Ethernet cable may be used.

Perle SR-100 Fast Ethernet Media Converter Installation Guide 12
Connecting the Terminal Block
The terminal block provides two power inputs. Both power inputs
can be connected to the SR-100 to provide redundant power to
the SR-100. If one power supply should fail the SR-100 will use
the other power supply to continue to power the unit without
interruption. Wiring with suitable temperature ratings must be
used. Use copper conductors only.
1. Ensure the power source is off prior to connection.
2. Strip both (12-20AWG) wires 7-8 mm(5/16th).
3. Loosen the terminal block screws and connect positive
(+)/negative (-) wires into the +/- terminals.
4. Tighten terminal screws (0.5Nm torque). Ensure the wires are
securely fastened.
5. If desired, connect P2 (power source 2, beginning at Step 1)
6. Turn on the power at source.
7. Check that the PWR LED light is lit.
8. Check LED indicators in the guide before and applying power
to the media converter.
9. Ensure that there is one individual conductor for each
clamping point.

Other Features
Auto-MDIX:
Auto-MDIX (automatic medium-dependant interface crossover)
detects the signalling on the 100BASE-T interface to determine
the type of cable connected (straight-through or crossover) and
automatically configures the connection.
Error Recovery:
In certain configurations, and under specific conditions where the
media converter brings down a link to convey status, there is
potential for a deadlock. Recovery is achieved by momentarily
restoring the link to see if the original failure has been resolved. If
it has not, the link will be forced down again, however if the
original problem has been resolved, the link will be restored

Troubleshooting
General
•Ensure power is supplied to the media converter.
•Ensure both devices on either end of the fiber are compatible.
If using a single fiber connection, ensure that you have both
an Upstream (U) and Downstream (D) media converter.
•Ensure all cabling is of the correct type and is in good
operating condition.
•For dual-stranded fiber connections, ensure the RX and TX
has been reversed between the 2 media converters.
No connectivity
If unable to get full connectivity with all DIP switches in the UP
position, the following procedure is recommended for
troubleshooting.
Method 1
1. Set the Link mode to Standard (SW3 – Down) on both media
converters. Leave all other switches in the Up position.
2. Connect the near end device to the copper connection. The
LKC LED indicates good copper connection. If the LKC LED
is not lit, then check the copper cable and the attached
device.
3. Repeat for the far end media converter.
4. Connect the fiber cable to both media converters. The LKF
LED indicates good fiber connection. If no LKF LED then
check the fiber cabling.
5. Return units to desired configuration.
Method 2:
The fiber connection can also be verified by configuring the
remote media converter for loopback mode. The LKF LEDs on
both media converters should be lit. Data should pass through the
local converter, over the fiber connection to the remote media
converter. At the remote media converter, the data will be looped
back and passed through the fiber, once again, to pass through
the local converter to the copper link.

Connecting the SR-100 to a DIN Rail
The DIN Rail clip will be attached to the SR-100.
Mounting the SR-100 on a DIN Rail
1. Position the SR-100 so that the top hooks of the DIN Rail clip
attach onto the top of the DIN rail.
2. Rotate the bottom of the SR-100 towards the rail. This will
snap the bottom hooks of the DIN Rail clip onto the bottom of
the DIN rail.
Removing the SR-100 from the DIN Rail
The DIN Rail attachment clip has a slot at the bottom of the latch
that is visible beneath the SR-100 when it is mounted.
1. Insert a flat blade screwdriver into the slot and twist the base
to release the clip. Alternatively, a downward force on the clip
will release the clip.
2. When the clip is released, pull the bottom of the SR-100 out
slightly and remove the SR-100 from the DIN rail.
