CHAPTER 2: Introduction

Printer Activity: This green LED on the top cover will light while data is being sent

to the twinax or 3270-coax printer. It will go dark when all data has been

transmitted to the attached printer.

Printer Error: This green LED on the top cover will go dark during print-server

operation. If there is an error condition, this LED will either light steadily or blink.

Mode: These two orange LEDs on the top cover are associated with the mode

button and indicate which print-server function is currently active. When both of

these orange LEDs are dark, the print server is in normal operating mode. Other

functions include the power-up self-test, EBCDIC self-test, ASCII self-test,

diagnostic dump mode, and restoring factory defaults.

Power: This connector is used for the 5-VDC, 2.5A power supply shipped with the

print server.

10/100BASE-T: This connector is used for attaching a 10BASE-T or 100BASE-T

cable.

10/100: This switch should only be used when the autosensing 10/100BASE-T

connector does not seem to function properly. The possible settings are shown

below. The DOWN position is achieved by moving the switches toward the bottom

of the print server.

Auto-sensing (default) UP UP

5250 Twinax: This DB9 port is where the twinax V-cable is attached to the print

server. The twinax line is then attached to the V-cable and the twinax printer. The

V-cable is self-terminating (so only one connector is attached, leaving the other

open).

3270 Coax: This BNC port is where the 3270-coax cable is attached to the print

server.

Diagnostic Port: This DB25 connector is where a standard PC type parallel printer

cable is attached for printing diagnostic reports.
