4 Tester Structure and Operation
4.1. Front Panel
Figure 4.1 shows front panel of the Tester where LED indicators, display
and keypad are located.
Figure 4.1 Front Panel
4.1.1. LED Indicators
LED indicators (LEDs) provide visual control of measuring conditions and
data transmission/reception.
LEDs are placed directly above the display. Both A and B ports are
provided with four LEDs each: Test, Rx, Tx, Link (left to right). Depending on
Tester operation modes, LEDs show different types of status information. On
the display under LEDs you can find captions describing mode of the Tester
and the LEDs.

12
LED Description
Test LEDs show port engagement in test fulfillment. At that, they can be of
three different colours:
−green – either “Loopback” or “Through” mode is on, or the port is
engaged in test fulfillment;
−orange – one of unfinished tests containing errors is being fulfilled at the
moment;
−red – the last test on the port was unsuccessful;
On-screen captions of Test LEDs can be as follows:
A->A – traffic transmission topology from Port A to Port A selected;
A->B – traffic transmission topology from Port A to Port B selected;
A->R – for asymmetric test mode - traffic transmission topology from Port A
to a remote point, or from a remote point to Port A selected;
B->A – traffic transmission topology from Port B to Port A selected;
B->B – traffic transmission topology from Port B to Port B selected;
B->R – for asymmetric test mode - traffic transmission topology from Port B
to a remote point, or from a remote point to Port B selected;
BERT – port is busy with “BER” test traffic reception/transmission;
CAB – port is busy with cable test signals reception/transmission;
DNS – port is busy with “DNS” test packets reception/transmission;
JIT – port is busy with “Packet Jitter” test traffic reception/transmission;
LB – “Loopback” menu option has been selected;
LB1 – Layer 1 “Loopback” mode is on;
LB2 – Layer 2 “Loopback” mode is on;
LB3 – Layer 3 “Loopback” mode is on;
LB4 – Layer 4 “Loopback” mode is on;
MDI – port is busy with MDI test traffic transmission;
MS – port is busy with “Multistream” test traffic transmission and
reception
OAM – ОАМ mode is activated;
PING – port is busy with “Ping” test traffic reception/transmission;
RCL – remote loopback control mode is activated;
SYNC – port is busy with “Synchronization” test traffic
reception/transmission;
RFC – port is busy with “RFC 2544” test traffic reception/transmission;
SCAN – port is busy with “IP Scanner” test traffic reception/transmission.
THRU – “Through” menu has been selected or “Through” mode is on;
TRR – port is busy with “Traceroute” test packets reception/transmission;
TRAF – port is busy with test traffic data reception/transmission.
РТР – port is busy with “PTP” test data reception or transmission.
Y1564 – port is busy with “Y.1564” test traffic reception/transmission.

13
Test LED caption is highlighted white in “Loopback” and “Through”
modes. Test LED caption is highlighted yellow on “Process Topology” menu
at traffic generation port and also during tests with traffic generation. Test LED
caption is highlighted red if the last test performed at that port was not
successful.
Rx LEDs report data reception status:
green – frames are being received at the corresponding port.
Green highlighting of Rx LED caption reports the port being test traffic
recipient, or “Loopback” or “Through” modes being on.
Tx LEDs report data transmission:
green – frames are being transmitted at the corresponding port.
Yellow highlighting of Tx LED caption reports the port being test traffic
transmitter, or “Loopback” or “Through” modes being on at that port.
Link LEDs report connection status:
Green – the corresponding port is connected
On-screen captions of the LEDs report transmission speed: 1000 for
1000BASE-T and 1000BASE-Х, 100 for 100BASE-T, 10 for 10BASE-T, NS –
no synchronization. “Н” symbol stands for half duplex mode and “F” symbol
stands for full duplex mode.
4.1.2. Display
Tester screen is represented by a coloured graphical LCD with 320×240
pixels resolution.
4.1.3. Keypad
The Tester is managed and alphanumeric information is entered by means
of the keypad.
Keys
– “On/Off” key (see Paragraph 9.5).

4.1.4. External Connectors
Figure 4.1.4 shows location of external connectors on the upper, lower and
lateral sides.
All connectors are marked on the housing of the Tester in accordance with
the denominations listed in Table 4.1.

* Note: To reset of the Tester, press the hidden reset button with a thin
blunt pin. At that, current settings are not saved, and next time the Tester is
switched on its settings will go back to the data saved when the Tester was
switched off normally last time (see Paragraph 9.5).

Figure 4.1.4 Location of Connectors
Connection of SFP Receiver/Transmitter
SFP A and SFP B connectors are used for connection of SFP optical
modules or SFP copper modules with external RJ45 to the Tester. SFP
modules supplied with the Tester and other modules can be used.
Please make sure that the receiver/transmitter and the connector support
the same physical interfaces before inserting the SFP module. Do not forget to
lock the SFP module latch. When inserting the SFP module make sure that its
label is facing the Tester front panel. When the module is installed it will be
securely fixed in the connector using the module’s locking latch. If the module
has been installed properly, you will hear a click.
Caution! If it is not easy to install the SFP module for the first time, please
do not exert extra force on it to avoid connector damage.
Before an SFP module (see Paragraph 10.21.6) is securely fixed, the
corresponding LED may already indicate its availability. Please make sure that
the module has been installed correctly.
Please use a rubber cap to protect a temporarily unused SFP module from
contamination.
Before removing an SFP module from the connector, disconnect fiber
optical plugs by pressing their latches and carefully take the cable out of the
receiver/transmitter. After that, unlock the SFP module latch and pull it to
remove the module from the connector.
Correct storage of SFP modules: you should use antistatic boxes or
packages and protect fiber optical connectors with rubber caps.
