6.1 INITIAL POWER-UP AND CHECK-OUT

I M P O R T A N T

Be sure AC power is available at the outlets. If the CPP or console(s) are turned on without AC power available, their internal UPS batteries will power the system until they are depleted.

1.Turn-on the printer and modem before powering-up the system.

2.Turn on the CPP power using the rocker switches on the front of each power supply.

If the Power Fail LED lights, press the RESET switch on the top of the power supply as shown in Figure 5-2.[Probable Cause: A magnetic latch is used to transfer AC from the main to the reserve power supply. A sufficiently hard bump in transit can cause the magnet to drop to the reserve position.]

3. Visually observe each card in the CPP.

The green and red LEDs should light as soon as power is applied. Within a few seconds, all red LEDs should be extinguished. Yellow LEDs will be lit on any cards designated a hot-standbys.

If red LEDs are lit on any CPP cards after an interval of 10 seconds, press the RESET button on that card and wait for the red LED to extinguish.

If the red LED continues to be illuminated, con- tact E.F. Johnson Technical Support for assistance.

Check to see that all CPP cards are properly seated and all plug-in relays are fully seated in their sockets.

If all CPP cards have green LEDs illuminated and there are no red LEDs illuminated, it may initially be assumed that the system is functioning properly.

4.Check the Printer Output Report. n The printer should begin to print the startup log immediately upon power-up. This printout will require several seconds to complete. Large systems may require nearly a minute to complete the report.

Check the printed report for any failure or error messages. If the individual consoles are not powered at the time of startup, off-line/failure messages will be printed for those consoles.

5. Plug in DC Appliqu’s.

To avoid accidental electric shock while initially working on the system, all LIC cards configured for DC control are shipped with the DC appliqu’s unplugged. Before placing the card in service, the ribbon cable from the appliqu must be plugged into P1 on the LIC card.

W A R N I N G

With the DC appliqu’s connected, as much as 200 volts may be present in the LIC card and the RTL control pairs. Use Extreme Caution!

6.Apply power to the Consoles. n Apply power to the individual console positions using the rocker switches on the front of each power supply.

Within 10 seconds of power-up, the console should establish communications with the CPP.

The clock will display "????". n When console/ CPP communications are established, the clock will display the time generated by the CSC real time clock. Note particularly the seconds readout. If the console is communicating properly with the CPP, the seconds count will advance smoothly with no gaps or delays.

As individual consoles are powered-up, the printer will log a report for each control tray and mod- ule tray at the position.
