The Model 24 has a green power LED and either four, eight, or ten red
activity LEDs. The green power LED will illuminate whenever power is
applied to the unit. The red LEDs indicate activity on the respective
port(s) when illuminated while the unit is in operation mode. All red
LEDs will illuminate briefly when the unit first powers up and goes
through its self-test. All red LEDs will stay illuminated while the unit is
in configuration mode (see Section 7 ).
When a computer sends a print job to the Model 24, the LED for the
computer port and the selected peripheral port will illuminate. The
computer LED will remain illuminated until a disconnection occurs as
described in Section 6.2.5 . The peripheral LED will typically remain
illuminated until the connection with the sending computer is
terminated. However, the peripheral LED may remain illuminated in the
event multiple computers are sending print jobs to that peripheral
simultaneously or if the printer/plotter attached to it goes off line (e.g.,
runs out of paper).
When a computer makes a connection to another computer through
Model 24, the LEDs for both computers will come on and stay on until a
disconnection occurs as described in Section 6.3.1 .
