Viavi HST-3000 Parts list manual

HST Ethernet Quick Card
The product comes in Ethernet only or Ethernet/T1/T3 variations and works in conjunction with
a fiber cleaning and inspection kit to help turn-up and maintain Ethernet backhaul links from the
cell site.
When connecting to an optical link first make sure the link is clean using the proper inspection
probes. Then connect the HST-3000 to the line under test using the proper SFP connector into
port 1 on the HST Ethernet SIM.

1 Testing with the HST-3000
This section describes testing using the HST-3000 located in the field. The first two sections
(Setting up an Electrical Link and Setting up an Optical Link) describe how one will connect the
unit to the link under test. Technicians serving as the loop unit (tests will be run by a far end
HST-3000, TB6000A, TB8000, or QT-600) can stop at this point. However, if the technician is
responsible for validating the link he or she must complete the next two sections of Quick
Testing and RFC 2544 testing. The final section details how to offload the RFC 2544 results
from the HST for storage or further analysis.
1.1 Setup for Testing an Electrical Link with the HST-3000
This section describes setup and testing to a RJ-45 connection located in the field. If testing to
an optical connection, proceed to the next section for instructions.
Step
Directions
1
The first step is turning the unit on and then
hitting the home key. Then select the Eth Elec
tab and select option 1 Terminate.
2
The unit will now boot up. Make sure to insert
the cable into the location (Port 1) on the left side
of the unit. Do not plug into the electrical cable
on the top of the unit.
3
The next step is to select Layer 2 Traffic as your
Test selection.

3
4
Now press the configure button on the tester.
Then select Auto Negotiation and depending on
the network select On or Off. This will most
likely be set to Off. Set the RFC 2544 Mode to
Disable.
5
Next press the right arrow key until you get to
the Link Init screen. Then set the speed to
100Mbps and the Duplex to Full. Next press the
home key.
6
You should see the screen turn green. If not,
select the display key and then select the
summary result pane. Then select the restart
key on the right side. If you cannot get to this
step check the settings and the physical
connection.
7
The tester is now ready to receive loop
commands or proceed to Quick Testing using the
HST-3000 (Section 4.3)

4
1.2 Setup for Testing an Optical Link with the HST-3000
This section describes setup and testing when the location in the field is an optical drop. If there
is instead an electrical RJ-45 handoff then the method detailed previously should be used.
Step
Directions
1
The first step is turning the unit on and then
hitting the home key. Then select the Eth
Optical tab and select option 1 1G Terminate.
2
The unit will now boot up. Make sure to insert
the proper SFP into the R/T 1 slot (top left of the
unit). The proper SFP will be either a 1310nm or
850nm optical SFP depending on the handoff.
3
The next step is to select Layer 2 Traffic as your
Test selection.
4
Now press the configure button on the tester.
Then select RFC 2544 Mode = Disable and
Auto Negotiation and depending on the network
select On or Off (most likely this will be set to
on). Next press the home key.

5
5
Now select the Action tab and then select Laser
On.
6
You should see the screen turn green. If not,
select the display key and then select the
summary result pane. Then select the restart
key on the right side.
7
The tester is now ready to receive loop
commands or proceed to Quick Testing using the
HST-3000 (Section 4.3)

6
1.3 Quick Testing Using the HST-3000
This section describes how to quickly check an active link exists between two test sets. This test
proves that the link exists and will detect if errors occur. After this section is complete one can
safely run the RFC 2544 test to validate the pipe.
Step
Directions
1
This section continues from either section 4.1 or
4.2. If you have not completed the appropriate
section, please do so at this time.
2
Press the configure button. Tap the left and
right arrows until you get to the Summary
Settings Screen.
Then Select:
•Loop Type -> Broadcast
•Tx Payload -> Acterna
•Frame Length -> Random
•Encapsulation -> Most Likely
this will be VLAN tagged though it
depends on the location and network
•VLAN ID and Priority ->
Depends on Network, see work order
•Traffic Load -> again depends
on network, see work order. If
unknown enter 1%.
3
Tap the Right arrow until you get the Ethernet
Tab.
•Frame Type -> 802.3
Please note that if you are running across a
switched service you have to set the Destination
MAC equal to the far end’s Source MAC
address on both testsets.
4
Tab right to select the Error Page.
Make sure that
•Error Type -> FCS
•Insertion Type -> Single

7
5
Tap right to select the Ethernet Filter Tab.
Make sure that
•Destination Type -> Don’t Care
•Source Type -> Don’t Care
•Encapsulation -> Don’t Care

Now to Loop up the far end select the Action
Key, then select #2 Loop and then Select #1
Loop Up.
8
You should see a message at the top stating
“Remote Loop Up Successful…”… If you do
not see this message please double-check your
settings. If the message still does not appear
repeat steps 1-6 for a far end HST and if using a
TB6000A or TB8000 do steps 1-6 in section 3.3.
9
Now select the Action key and then select Start
Traffic. Check that the Frame LED on the top of
the unit becomes illuminated.
