Validating Ethernet Service

The toner detects link pulses for 10BASE-T, 100BASE-TX,
and 1000BASE-T Ethernet service on pins 1, 2 and 3, 6 of
its RJ45 jack.
1. Turn off the toner.
2. Connect the toner to the circuit as shown in Figure 4.
3. Turn the toner's rotary switch to SERVICE.
4. The Ethernet LED indicates service on pins 1, 2 or 3, 6
as shown in Figure 4.
The toner checks for continuity between pins 4, 5.
Continuity indicates the toner is connected to a network
device that is turned off.
If the Ethernet LED alternates between red and
green, the Ethernet service is Auto-MDIX.
