Installation

The default DIP switch settings (all switches in the UP position)
will work for most installations.

These are the steps required to configure the Perle S-1110-XT
Ethernet media converter:

1. Insert SFP Module (SFP Model only).

2. Set the Auto-MDIX jumper setting (optional).

3. Set the DIP switch settings (if required).

4. Set the Powering Option Jumpers (if required).

5. Install and connect the fiber cable(s).

6. Install and connect the copper cable(s).

7. Power up the media converter.

Auto-MDIX Jumper Settings

Note: The factory settings for Auto-MDIX will work for most
installations, but in the rare case that you need to modify the
settings, the procedure is below.

To access the Auto-MDIX jumper settings, unscrew the six side
screws on the case and remove the cover plate. Locate the MDIX
AUTO jumper set as detailed below. By covering or strapping pins
1 and 2, the S-1110-XT will operate as an MDIX device. By
covering or strapping pins 2 and 3, the S-1110XT will
automatically detect the Ethernet cable’s polarity. Removing the
strapping is the same as AUTO.

Note: The default jumper setting is AUTO

DIP Switches

The DIP switches are accessible through the opening in the side
of the enclosure.

Note: All switch changes take effect immediately.

DIP Switch Settings

Auto Negotiation copper (Switch 1)

Switch Position Copper
Up (default) Auto
Down Off

Note: Auto negotiation should only be turned off, if the copper link
partner does not support Auto Negotiation and fixed settings are
required by the copper link partner.

Perle 10/100/1000 Ethernet Extended Temperature Media Converter

Installation Guide

Auto: When enabled, the media converter will negotiate with its
link partner to determine the most optimal parameters for this
connection. The S-1110-XT will advertise capabilities of 10,100
and 1000 Mbps, full and half duplex as well as pause, and remote
fault capabilities to the link partner.

If the copper link partner does not support Auto negotiation, the
S-1110-XT will parallel detect to 10 or 100 Mbps and force Half
Duplex mode as per IEEE specifications.

Off: When the Auto Negotiation switch is set to the OFF position,
the media converter will not negotiate the Ethernet parameters
with the copper link partner. The parameters used by the media
converter will be determined by the Duplex (switch 4) and Speed
(switch 5) DIP switch settings.

.

Link Mode (Switch 2)

Switch Position Mode

Up (default) Standard Mode
Down Smart Link Pass-Through

Standard Mode: In this mode, link on the fiber and copper sides
can be brought up and down independently of each other. A loss
of link on either the fiber or copper port can occur without affecting
the other connection.

Smart Link Pass-Through 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 set-up for Smart 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 link at the near end
device.

Fiber Fault Alert (Switch 3)

Switch Position Fiber Port
Up (default) Enabled
Down Disabled

Enabled: If the media converter detects a loss of signal on the
fiber receiver, it will immediately disable its fiber transmitter signal
on the same port. 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 Fiber Fault Alert (FFA)
and the local media converter is set up with Link Pass-Through, a
loss of fiber link will be passed through to the local copper
connection thus notifying the connected device.

If the media converter has been set to Smart Link Pass-Through
mode, the effect will be the same as FFA, since the link loss on
the fiber receiver will result in bringing down the copper link, which
will in turn cause the transmit fiber link to be brought down.

Note: This feature only takes effect if Fiber Negotiation has been
turned off.

Disabled: The media converter will not monitor for or generate
Fiber Fault Alert.

Link Mode is set to Standard.

Duplex copper (Switch 4)

Switch Position Copper port
Up (default) Full Duplex
Down Half Duplex

Note: When Auto Negotiation (SW1) is set to Off, the media
converter will use this Duplex setting for the copper port.

position for normal operation. The switch must be set to this
position in order 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 data link will be disabled; however power to the
powered devices will be maintained. This mode will override all
other switch settings.

Installing the SFP Fiber Module

Troubleshooting
General

1. Ensure power source is connected.

2. Ensure the remote device’s fiber connection type is

compatible with the media converter. If using a simplex
fiber connection, ensure that you have both an Upstream
(U) and Downstream (D) media converter.

3. Ensure all cabling is of the correct type and is in good

working order.

4. For duplex fiber connections, ensure the RX and TX has

been reversed between the two media converters.

No connectivity

If unable to get full connectivity with all DIP switches in the UP
position, this procedure is recommended for troubleshooting.

Method 1

1. Set the Link Mode to Standard on both media converters.
Leave all other switches in the Up position.

2. Connect the copper device to the copper port on the media
converter. The LKC LED light indicates good copper
connection. If the LKC LED is not lit, 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, check the
fiber cabling. Ensure the transmitter and receiver pairs are
crossed.

5. Return the units to the desired configuration. Connect the
power source to the Media converter.

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, back to the local converter and
passed to the copper link.
