LAN SOLUTION NETWORK TESTER
Rtr must be on MyIP LAN segment —This is displayed in
Setup while setting the Manual router IP address. The
LAN Solution Network Tester requires that the router
be at an IP address on the LAN segment as defined by
the Netmask and MyIP addresses. Setup will not allow
the router IP address to be set to an off-LAN address.
Voltage Found, SEL Jack ID—The tester does not
operate in Network modes when voltage, and possibly
destructive power, is found. Voltages found will
terminate the test in progress and the only option is to
run the Jack ID test (by pressing SEL). The only
exception to this is the possibility of an Ethernet power
source providing power between the 1–2 and 3–6 pairs.
In that case, the following message will be displayed:
Enet Pwr source found = xV—Some devices provide
power for IP phones or wireless transceivers on the
same wires that carry the Ethernet data signals. They
do this by connecting a voltage to the center taps of
each transformer in their Ethernet interface. The
LAN Solution Network Tester reports this and allows
the network testing to continue.
