Network Card Leds - Tektronix Phaser 740 Service Manual

Network card LEDs

The Ethernet port has two LED indicators. The LEDs are also found on the Ethernet
network card used by the Phaser 740 printer:
TX indicator (yellow); blinks while data is transmitted to the host. The LED
is off while no data is being sent.
Twisted Pair (100baseT). RX indicator (green); blinks while the network card
is receiving data. The LED is on steady while no data is being received. If the
LED is off steady, then a problem (probably hardware) has occurred at the
network hub.
ThinNet (100base2). RX indicator (green); blinks while the network card is
receiving data. The LED is off steady while no data is being received. If the
LED is on steady, then a problem (probably hardware) has occurred at the
network hub.
TP Link. On steady indicates good circuit to nearest port; off indicates no
circuit.
100 MBS. Ethernet speed is 100 MBS when lit.
Note
Do not use both Ethernet connectors at the same time. With a
Ethernet network card or Token Ring network card installed, the built-
in Ethernet port is disabled.
The Token Ring network card has two LED indicators:
Connection (yellow); off when the printer is not inserted into the Token
Ring, blinks while the printer is attempting to insert itself into the Token
Ring, on when the printer is properly inserted in the ring.
Ring Speed (green); off when the card is set for 4 megabits-per-second
(MBPS), on when the card is set for 16 MBPS.
When both LEDs blink, a network card failure has occurred.
