cord to the power cord connector on the back of the
ELS100-16TX.
The ELS100-16TX is not equipped with an on/off switch.To power-
up the unit, connect the power cord to a 120VAC or 240 VAC
single-phase stress grounded outlet.
Checking the Power-up Diagnostics Sequence
Before connecting any devices to the ELS100-16TX, power on the
unit and observe the power-up diagnostics sequence to check for
proper operation.
To observe the power-up diagnostics sequence completely, you
may want to repeat it.To restart the power-up sequence press the
reset switch on the front panel.
When you power up the ELS100-16TX, the following occurs:
1. The Power (Pwr) LED is on.
2. The CPU LED starts flashing.Two of the Port Status Mode
LEDs are on.

Connecting UTP Cables
Before connecting a segment to the ELS100-16TX, check each
end of the segment to verify wire crossover.
Connect a twisted pair segment to the ELS100-16TX as follows:
1. Ensure that the device at the other end of the segment is
connected to the segment and is powered ON.
2. Connect the twisted pair segment to the ELS100-16TX by
inserting the RJ45 connector on the twisted pair segment into
the desired RJ45 port (refer to upper figure).
3. Verify that a Link exists by checking that the port LINK LED is
on (solid green).If the LINK LED is off, perform the following
steps until it is on:
a. Check that the 100BASE-T device at the other end of the
twisted pair segment is ON and connected to the segment.
b. Verify that the RJ45 connectors on the twisted pair segment
have the proper pinouts (refer to lower figure) and check the
cable for continuity.
c. Check that the twisted pair connection meets the dB loss
and cable specifications.
If a link is not established, contact the Cabletron Systems
Global Call Center.Refer to the Getting Help section at the
beginning of this guide for details.
4. Repeat step 2, above, until all connections have been made.

Installing an Ethernet Port Interface
Module (EPIM)
The ELS100-16TX provides two slots for a Cabletron EPIM-100FX
(Ethernet Port Interface Module).The ELS100-16TX is shipped
without EPIMs.To install an EPIM, follow the procedure below:
1. Remove the coverplate or the existing EPIM (whichever
applies).
2. Slide the new EPIM into place, making sure that the
connectors on the rear of the EPIM align correctly and firmly
with the connector inside the ELS100-16TX. Refer to figure.
3. Install the mounting screw.
Caution: When removing an EPIM, pull the module straight out to
prevent damage to the connector.
Only qualified personnel should perform installation
procedures.
Note: The EPIM is hot swappable. Also, the RJ45 port
corresponding to the EPIM port is disabled once an EPIM is
installed.

Connecting a Multimode Segment to the
EPIM-100FX
The EPIM-100FX has an SC style network port. Cabletron
Systems supplies fiber optic cable that uses SC style connectors
that are keyed to ensure proper crossing over of the transmit and
receive fibers.
Fiber Optic Network Connection
1. Remove the protective plastic covers from the fiber optic ports
on the applicable port on the module and from the ends of the
connectors.
2. Insert one end of the SC connector into the EPIM-100FX
installed in the ELS100-16TX.
3. At the other end of the fiber optic cable, attach the SC
connector to the other device.
4. Verify that a Link exists by checking that the port LINK LED is
on solid green.If the LINK LED is off, perform the following
steps until it is on:
a. Check that the cable is properly connected at both ends.
b. Check that the power is turned on for the device at the other
end of the Link.
c. Verify proper crossing over of fiber strands between the
applicable port on the ELS100-16TX and the fiber optic
device at the other end of the fiber optic link segment.
d. Verify that the fiber connection meets the dB loss
specifications.
If a Link has not been established, contact the Cabletron Systems
Global Call Center. Refer to the Getting Help section in this guide
for details.
Caution: An odd number of crossovers (preferably one) must be
maintained between devices so that the transmit port of one
device is connected to the receive port of the other device and vice
versa.
If the fiber optic cable being used has SC style connectors that do
not resemble MIC style connectors, or has SC connectors on one
end and a different type on the other, such as ST connectors,
ensure that the proper crossing over occurs.
Caution: Do not touch the ends of the fiber optic strands, and
do not let the ends come in contact with dust, dirt, or other
contaminants.Contamination of the ends causes errors in
data transmissions.If the ends become contaminated, clean
them with alcohol using a soft, clean, lint-free cloth.

Connecting the Local Console Manager
to aTerminal
The Local Console Manager (LCM) is a command-line interface
for configuring, monitoring, and managing the ELS100-16TX
through the out-of-band RS232C connection on the front panel.
To connect LCM:
1. Connect your VT series terminal or terminal emulator to the
out-of-band management RS232C port on the front panel of
the ELS100-16TX using the twisted pair cable with RJ45
connectors shipped with the unit. (Only three of the nine wires
are necessary: Receive Data, Transmit Data and ground.)
2. Set the terminal to 9600 baud, 8N1: 8 data bits, no parity, 1
stop bit, and no flow control.
3. Press the Enter key several times.If the ELS100-16TX is
operational, LCM responds with the
ELS100-16TX >
prompt.
LCM is now ready to use. Refer to the SmartStack 100
ELS100-16TX User’s Guide for an overview of LCM and the
command syntax. LCM commands for the ELS100-16TX are
provided in the User’s Guide in chapters dealing with those topics.
A complete list of LCM commands appears on the following pages.
