2.3 The Print Server’s External Components
The Ethernet to Twinax/Coax Print Server has labels on both the top and bottom
panels that indicate what the switch and each of the connectors and LEDs are.
Please refer to these labels as you read the rest of this section.
2.3.1 LED I NDICATORS
The Ethernet to Twinax/Coax Print Server has these LEDs on its left side and top
panel:
Link: This green LED on the side of the print server indicates that the print server
has established communication with an Ethernet hub and has verified link
integrity.
Activity: This green LED on the side of the print server indicates that the print
server is detecting signals on the network.
Power: This green LED on the top cover will light to indicate that the print server
has successfully completed its internal self-tests and is ready to operate. If this light
blinks slowly, the print server is not in operating mode (for example, during flash
upgrade). A rapidly blinking light indicates a problem with the print server (for
example, a failed self-test, faulty power supply, etc.).
Line Sync: This green LED on the top cover will light to indicate that the print
server is connected to a twinax or 3270-coax printer and that the printer is turned
on. During the power-up cycle, this LED will blink while the print server is
connecting to the twinax or 3270-coax printer. For twinax printers, it will blink
about two times per second. For 3270-coax printers, it will blink about four times
per second. The default setting for the print server’s printer connection is twinax.
LAN Data: This green LED on the top cover will light when network data is
received by the print server. This light may seem to be blinking at times since the
print server receives many small data packets in the form of status requests or other
inquiries by servers in the network.
