Connection of SFP Receiver/transmitter
SFP A connector is used for connection SFP optical modules or SFP
copper modules with external RJ-45 to the Tool. SFP modules supplied with
the Tool 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 Tool’s 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 is securely fixed, the corresponding LED already
indicates 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.

9 Operation Procedure
9.1 Connection Variants
Tests with traffic generation are the following: traffic test, RFC 2544 test,
packet jitter test, BERT, Multistream test. To run these tests, you should
connect MAKS-EM Tester or MAKS-EMB Tool to a network section or DUT in
accordance with the connection diagram illustrated in Figure 9.1. Either
MAKS-EM or MAKS-EMB in Analyzer modification can act as network tester.
Either MAKS-EM or MAKS-EMB in both Analyzer and Loopback modifications
can act as a loopback tool.
Figure 9.1 Tester and Tool Connection in Test Mode
Network sections with distant loopback point are usually tested in
accordance with the above-mentioned diagram. At that, loopback level (from 1
to 3) is selected depending on the network equipment used within this network
section. For example, if a network section involves only network commutators
(switches), you will have to activate Level 2 Loopback function, but if this
section involves routers, you will have to switch on Level 3 Loopback function.
For more on Loopback function, see paragraphs 9.2.2 and 9.3.3.

18
9.2 Manual Operation
9.2.1 Connection Speed
To set the required connection speed, press speed selection key Sin the
group 10, 100, and 1000 and select one of the three variants:
10 MBps;
10 or 100 MBps;
10 or 100 or 1000 MBps.
After pressing the key, LED indicating the selected mode will flash for three
seconds. (Refer to Table 3.2). After this procedure, speed self-matching and
setting will be performed automatically at the highest of the available selected
speeds. Connection status LED LINK will light up if synchronized. If there is no
synchronization at any of the selected speeds, the LEDs will continue flashing.
9.2.2 “Loopback” Mode
“Loopback” function allows testing a network without changing its
settings. Such a test can be run at different OSI levels:
-at physical level: all incoming frames are looped back inversely. At that,
their structure does not undergo any changes.
- at data link level: incoming frames are looped back inversely. It is
possible to activate algorithm of source and destination MAC address
swapping and algorithm of MAC address shifting at loopback. Frames
containing identical source and destination MAC field data, OAM frames, ARP
requests and multicast frames are hard filtered at reception and are not looped
back inversely.
-at networking level: incoming frames are looped back inversely. It is
possible to activate algorithm of source and destination IP address swapping
at loopback. When network level loopback is activated, settings of the above
mentioned swapping and shifting algorithms for data link level are also
effective.
To activate physical, data link, networking or transport level loopback,
press loopback level selection key L of the L1, L2, L3 and L4 group. Select the
required loopback level or deactivate loopback by pressing Lkey. LED
indicating the selected mode will flash for three seconds to show the current
choice. (Refer to Table 3.1).When loopback is activated, number of the
flashing LED will correspond to the selected loopback level. If loopback is
deactivated, all LEDs will be off.
When second level loopback is activated, frame fields of source and
destination MAC address will swap automatically.
When third level loopback is activated, not only source and destination

19
MAC address but also source and destination IP address frame fields will
swap automatically.
When fourth level loopback is activated, not only source and destination
MAC and IP addresses but also source and destination TCP/UDP ports will
swap automatically.
Additional parameters of different level loopback can be configured via
Remote Management Software (Refer to Paragraph 9.3.3).
9.3 Remote Management
Remote MAKS-ЕМB management allows configuring Tool parameters,
setting and launching tests as well as viewing and saving test results. USB and
LAN ports are designed for remote management of the Tool.
9.3.1 Remote Management via USB
USB port (see Figure 3.2) is used for remote MAKS-EMB management. To
organize an interface between the Tool and PC you should install a driver
package for virtual CP210x_VCP_Win2K_XP_S2K3.exe. COM port
emulation. When the driver is installed, connect the Tool to PC via USB cable.
New COM port will appear on Device Manager.
9.3.2 Remote Management via Ethernet
Remote management via Ethernet is one of the Tool’s options (“05-RC”).
To manage the Tool, connect its LAN connector to the network using a
patch cord (see Figure 3.2). Configure the second Ethernet interface used for
remote management by means of Remote Management Software: “Interface
Settings”, then “Remote Management Port”.
Note: When the Tool is remotely managed via Ethernet, “Screen Shot”
function is disabled.
9.3.3 Working with Remote Management Software
Start EMRemote.exe program. Dialogue box of the program is illustrated in
Figure 9.3. The program is common for MAKS-EM and MAKS-EMB but it can
manage only one tester/tool at a time.
