1. DESCRIPTION
1.1. The SEM2000C01
The SEM2000C01 is a synchronization master generator for use in synchronous Ethernet
networks. It provides two electrical ports that operate at 10Mbit/s, 100Mbit/s and
1Gbit/s and one optical port that can operate at 1Gbit/s and 2.5Gbit/s.
The electrical ports can automatically negotiate their datarates as well as operation in
full duplex or half duplex modes (FD/HD). The operating mode and datarates can also be
user-selected. The optical port must be configured according to the capabilities of the
SFP modules installed.
The ports of the SEM2000C01 always operate in master mode, guaranteeing that all the
links with any equipment that connects to the SEM2000C01 will use its reference clock.
The reference clock can be sourced from a GNSS receiver module installed in the same
mounting frame, such as the GPS2001C01, or from an internal oscillator with a
frequency stability of ±1ppm. Information regarding the reference being used is
communicated to the devices connected to the SEM2000C01 via the Ethernet
Synchronization Message Channel (ESMC) as per the ITU-T G.8264 standard.
It is possible to monitor the SEM2000C01 status remotely using a communications
controller module installed in the same mounting frame. In addition, certain controller
modules provide SNMP management and the ability to record events in a file including
date and time information for further analysis.
The SEM2000C01 is a TL2000 terminal line module and can be housed in a two rack unit
(2 RU) UR2000 mounting frame.

3. INSTALLATION
THE SEM2000C01 MODULE CONTAINS ELECTRONIC DEVICES SENSITIVE TO
ELECTROSTATIC DISCHARGE. Always use antistatic bags clearly identified
with a high degree of shielding for storage and transportation.
3.1. Initial inspection
Verify that the package has been properly handled during transport. After opening the
packaging, check that the SEM2000C01 module is inside.
You must notify your Albalá Ingenieros distributor or dealer of any damage or defects
observed.
Follow the instructions in this manual to install this module in the mounting frame.
3.2. Safety instructions
When the module incorporates any optional SFP/SFP+ optic fiber transmitter provided by
Albalá Ingenieros, the SEM2000C01 is a CLASS 1 LASER product as per the IEC 60825-1
standard. Please read the safety instructions included in this manual carefully before
using this module.
•The SEM2000C01 may contain an SFP/SFP+ fiber optic transmitter module
with laser diodes. These modules are CLASS 1 LASER products. Due to its
features this device is inherently safe. However, exercise CAUTION as there
is invisible laser radiation in the module's fiber optic connectors. Avoid
exposure to the beam. NEVER lift or remove the cover of the SEM2000C01's
optical connectors except to connect a fiber optic connection, and be sure
that the power is off when doing so. NEVER leave optical connections that
are carrying signals disconnected from the equipment. NEVER examine a
fiber optic connector with a microscope without being absolutely certain
that no optical signal is present, as this could cause serious damage to the
retina.

•This equipment must be connected to a mains outlet with a protective
earth connection. Never use extension cords that do not have protective
earthing connection. The lack of an effective electrical connection between
the ground pin in the mains input connector of the equipment and the
protective earth of the electrical power distribution can cause serious harm.
•All modules of the Albalá Ingenieros TL2000 terminal line can be
hot-plugged or unplugged without suffering any damage or affecting the
processes that are currently taking place in other modules in the same
mounting frame.
•The SEM2000C01 module and the mounting frame should always be
installed, maintained, operated and removed by personnel with sufficient
technical qualifications. The equipment should never be placed in damp
areas, near splashing liquid, or in explosive or corrosive atmospheres.
Neither modules nor mounting frames can be used in applications that
could endanger human life.
3.3. Environmental considerations
This symbol indicates that this equipment must be deposited at a collection
point for proper waste treatment once it has reached the end of its useful
life.
3.4. Installation of SFP/SFP+ modules
The SEM2000C01 features receptacles to install optional SFP/SFP+ modules for signal
transmission or reception over optical fiber or other functions. To install or uninstall one
of these modules in the equipment, follow the instructions given below.
To install, insert the SFP/SFP+ module into the receptacle and slide it carefully until it
clicks, indicating that the module has reached its final position.
To uninstall, first remove any optical or electrical cables that are connected to the
SFP/SFP+ module. Then lift the metal ring located at the opening of the SFP/SFP+
12

Albalá Ingenieros | Manual SEM2000C01
module to disable the module's retention mechanism and release it. Finally, pull module
carefully out of its receptacle.
There are different types of SFP/SFP+ modules. Make sure that module to be installed is
appropriate for the receptacle that will contain it.
3.5. Installing the module in the mounting frame
The following steps should be followed in order to install a SEM2000C01 module in the
mounting frame.
1 - Remove the blank panel covering the front of the empty slot chosen for installing the
SEM2000C01 in the mounting frame.
2 - Insert the SEM2000C01 module into the front of the mounting frame. The edges of
the card slide into two plastic guides inside the mounting frame.
3 - Secure the module to the mounting frame using the two front screws.
After these steps, the module is ready to be connected to other equipment.
3.6. Interconnection
The arrangement of the front panel connectors of the SEM2000C01 module is shown in
the following figure.
Front panel of the SEM2000C01
The two RJ-45 connectors labeled PORT 1 and PORT 2 are electrical interfaces for
13

Albalá Ingenieros | Manual SEM2000C01
connection to 10Base-T, 100Base-T or 1000Base-T local area networks (LANs) as per IEEE
std 802.3. The receptacle labeled OPTICAL PORT is for the installation of an SFP module
and allows connection to 1000Base-SX, 1000Base-LX or 1000Base-CX LANs as per IEEE
std 802.3.
The front panel has not been designed to support mechanical stress. All cabling in the
rack where the mounting frame is located should be properly supported so that the front
panel does not provide mechanical support.
3.6.1. Connecting to the electrical ports
Connections to the electrical ports are made with RJ-45 connectors. The cabling used
should be UTP Category 5 or better (Cat 5e o Cat 6) in order to guarantee proper
operation at 1Gbit/s.
3.6.2. Connecting to the optical port
The SFP fiber optic module must be inserted into its housing as described previously
before interconnection. Modules for fiber optic transmission using the 1000Base-LX,
1000Base-SX as per IEEE std 802.3 or modules for transmission via cabling using
1000Base-CX as per IEEE std 802.3 can be installed.
If SFP modules using 1000Base-SX as per IEEE std 802.3 are used then the fiber optic
cabling used must be multimode. Such modules are appropriate for links of up to a
few hundred meters. If SFP modules using 1000Base-LX as per IEEE std 802.3 are used
then multimode fiber optic cabling can be used for short distances (up to 500 meters)
however monomode fiber optic cabling must be used for links that extend up to five
kilometers.
Optical connections are performed in the SFP/SFP+ module, which is equipped with
LC/PC connectors. Connectors using single-mode fiber optics are usually blue.
Connectors for multimode fiber optics are usually gray.
All fiber optic cables have a minimum curvature radius that must be obeyed (consult
the specification of the cabling used) and should be run with enough strain relief to
absorb small, unintended pulling or mechanical stress.
Before connecting the fiber optic cabling, remove the protective endcap. Any unused
fiber optics must be covered by their endcaps.
Fiber optic connections are sensitive to dust and dirt. Any dust or dirt particles trapped
in the optical pathway act as attenuators of unknown value and in the worst case can
render the signal unusable. Care must be taken to ensure the cleanliness of and not to
dirty the connectors during insertion and removal of the fiber optic cables.
In systems designed for transmission over 1000Base-CX cabling as per IEEE std 802.3
the SFP modules and the cable are joined together and the only way to remove them
is to extract the module from its receptacle.

4. OPERATION
This section describes the significance of the front panel indicators of the SEM2000C01
module and their remote control and monitoring ability.
4.1. Front panel description
The appearance of the front panel and the elements it contains are shown in the
following illustration.
Front panel of the SEM2000C01
In addition to the connectors previously described in the Interconnection section the
front panel includes the following indicators and controls:
Each of the two electrical ports has an associated green LED that lights up when the link
operates at 1Gbit/s, stays off for other datarates and a yellow LED that both lights up to
indicate that the link has been established and blinks when there is activity. The optical
port has a single associated yellow LED that lights up when the link has been
established.
The REF. LED lights up in green when the presence of a 10MHz signal is detected on the
rear bus. Otherwise this LED lights up in red.

Albalá Ingenieros | Manual SEM2000C01
4.2. Functional description
The SEM2000C01 operates as a three-port Ethernet switch without management
capability. No adjustments are necessary to use synchronous Ethernet functionality. The
SEM2000C01 periodically sends a Synchronization Status Message (SSM) to all the
devices connected to it as per the ITU-T G.8264 standard. The SEM2000C01
automatically chooses which clock to use as a reference, giving priority to the 10MHz
signal coming from a GNSS receiver module installed in the same mounting frame, such
as the GPS2001C01. If this signal is not available, an internal oscillator is used with a
frequency stability of ±1ppm.

4.3. Module remote control and supervision
The SEM2000C01 can optionally be remotely controlled/supervised.
In order to perform remote configuration and supervision of the module an optional
TL2000 family remote communications controller must be installed in the mounting
frame.
The main function of the communications control module is to interface between a
10/100 Ethernet port and the internal bus of the mounting frame. The following
illustration shows the most common control situations: from a computer or control
panel via Ethernet.
Certain communications control modules provide additional, more advanced functions
such as an SNMP agent, logging of status changes of the modules and a Web interface
for remote control, etc.
Software for simple configuration and supervision with a GUI for multiple modules can
be downloaded from the Albalá Ingenieros website.
17

Albalá Ingenieros | Manual SEM2000C01
The following functions of the SEM2000C01 can be performed remotely:
- Configuration of the datarate and the operating mode for the ports.
- Supervision of the status of the links that are established in each port.
- Supervision of the status of the 10MHz reference.
4.3.1. Details of the SEM2000C01 registers
The SEM2000C01 module provides control and status registers that can be read and
written by means of specific commands described in the communication control
module user manuals.
The parameter information grouped in the CONTROL or RAM sections is stored in
volatile memory. Any modifications to the parameters will be lost when the module
power supply is disconnected unless the "EEPROM Save" button within the software
has been pressed.
The STATUS section parameters are read-only and cannot be modified.
The EEPROM section parameters are rarely used and are stored directly in non-volatile
memory.
The parameters that can be controlled and supervised remotely for each version of
the firmware are listed below:
