Configure an IPv4 Address
To manually configure an address:
1. Tap IP to open the IP address screen.
2. Enter the IP address.
An IPv4 address is 32 bits represented in dot-decimal notation. The address consists of
four groups of decimal digits (0 to 255) separated by a dot or period. The UI has a separate
entry field for each group of digits.
Examples of valid IPv4 addresses:
8.8.8.8 (Google DNS servers)
192.168.10.1
10.10.10.1
Examples of invalid IPv4 addresses:
0.0.0.0
255.255.255.255
An address with “0” as the first byte
An address with a decimal number greater than 255
224.0.0.0 /4
127.0.0.0 /8
3. Tap Subnet Mask, scroll if needed, and tap a subnet mask.
The Product shows subnet mask notation for example, 255.255.0.0. The corresponding
prefix length values are /1 to /31.
An IPv6 address is 128 bits represented as eight groups of four hexadecimal digits (16 bits)
with a colon between each group. The UI has a separate entry field for each group of digits.
Examples of valid IPv6 addresses:
2001:4860:4860::8888 (Google DNS servers)
2001:0db8:0000:0000:8a2e:0000:0370:7334
Examples of invalid IPv6 addresses:
0:0:0:0:0:0:0:0
ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff
ff00:: /8
::ffff:0:0 to ::ffff:ffff:ffff
Because IPv6 addresses can be long, there are valid ways to shorten them.
Omit leading zeros within a group. In the second example of valid addresses above, the
second and seventh groups may be shortened to db8 and 370, respectively.
If two or more adjacent groups contain 0000, replace them with two colons as in the
first example above.
If a group contains 0000 and is not adjacent to another group that contains 0000,
replace it with one zero.
According to the rules above, the full address of the first example is:
2001:4860:4860:0000:0000:0000:0000:8888, and the shortened address of the second
address is 2001:db8::8a2e:0:370:7334.
3. Tap Subnet Mask, scroll if needed, and tap a subnet mask.
Although the Product uses the term subnet mask, the prefix length from /1 to /127 shows.
Use caution when working in potentially hazardous locations such as an elevated
location on a ladder or roof top, especially if work is occurring in proximity to a
lightning storm. Also use caution if external communication cables are run at
length in parallel to electrical power installation cables. These types of
installations can expose communication cables to coupled electrical transients
that could be accessible on exposed conductive parts of the equipment during
operation. While in general these transients are not expected to be an electric
shock hazard, startled reaction from these transients could lead to a secondary
hazard such as loss of balance and lead to a fall or other injury. To reduce risk of
exposure, limit contact to accessible conductive parts of I/O terminals during
operation.
Cable Tests
In a twisted pair cable test, the Product performs a series of radio frequency (RF) tests to
determine the transmission parameters of the cable. The parameters are compared to the test
limits specified by IEEE 802.3 for Ethernet. Unlike transmission testers that pass bits across
the cable, the Product evaluates the physical qualities of the cable.
Measures length up to 304.8 m (1000 feet)

ItemDescription
Pairs 1,2 are the shortest pair of the cable and open at 43.1 m.
The Product detected the Remote ID, and the wire map failed. The wires are not
wired correctly based on the settings selected for the test.
The wire map shows how the cable is wired. The wire map passes or fails based
on the settings selected for the test. For this test, the settings are set to test:
A straight through cable (Allow Crossover can be on or off to test a straight
through cable).
The continuity of the shield on the cable (Shield > )
The test limit is set to ≥1000BASE-T (1G) to verify a 4-pair cable.
The continuity of the shield fails because the continuity of the shield cannot be
verified.
Because the wire map failed, the Product cannot test the performance
capability of the cable.
Open Pairs Failure
Figure 3 shows a wire map of a cable test that fails because wires 4, 5, 7, and 8 are open. The
wires are not connected on the far end and the test limit is set to ≥1000BASE-T (1G) to verify a
4-pair cable. With a test limit set to 10BASE-T or 100BASE-TX, the wire map of the cable test
passes. The length of the wires on the wire map indicates the distance to the open.
Figure 4 shows a wire map that fails because wires 1 and 2 are shorted together. The length of
the wire on the wire map indicates the distance to the short. With wires shorted together, the
Product cannot detect the Remote ID. Repair the short and do the test again to verify the wire
map of the other pairs.

Split Pairs Failure
Figure 5 shows a wire map of a cable test that fails because pairs 3,6 and 7,8 are split pairs.
The Product can do switch connectivity, Ping, and Power over Ethernet (PoE), and tests.
Switch Connectivity Tests
In a network test, the Product performs a series of queries to determine and report information
about a switch or device. The Product determines information about the device and reports
advertised data rates with full-duplex or half-duplex. See Switch Test Results.
Ping Tests
The Product supports IPv4 and IPv6 addresses. Both protocols may be configured based on
what is available on the network.
With Ping enabled, the Product pings the device specified in Settings > Ping and the DNS
servers and gateways that the Product detects. The Product pings each device four times with
a 1 second threshold timeout for each attempt and shows:
If an IP address is accessible.
The round-trip response time in milliseconds (ms).
Power over Ethernet (PoE) Tests
With PoE Test enabled, the Product automatically does a PoE test after the completion of a
network switch test.
Definitions:
Power Sourcing Equipment (PSE) is a device, such as a switch, that can provide PoE.
A Powered Device (PD) is a device that can receive PoE from a PSE.
PoE negotiation standards are defined in IEEE 802.3af/at/bt.
In a PoE test:
1. With the Product connected to a PSE, the Product acts as a PD and starts a hardware
negotiation with the PSE.
2. If the PSE is compliant with the IEEE 802.3 standard, the Product determines the maximum
power the PSE can offer (Class 0 to Class 8).
3. The Product places a load on the PSE to determine if the PSE delivers the power required
to meet the negotiated hardware power class at the PD.
4. If the PSE meets the hardware negotiation power class, the Product attempts a software
negotiation with LLDP/CDP to determine the software power level offered.
5. The Product places a load on the PSE to determine if the PSE delivers the software
negotiated power at the PD.
When the Product receives a compliant LLDP or CDP packet from
a device, the summary button shows the:
