PART 4. POWER-UP PROCEDURE
4.1 Connect Power to the System (Figures 4-1 and 4-2)
It is recommended that you verify system operation and then make the external connections. The
procedures are as follows:
Ø
Remove any cables for external connections from the system if you have already plugged any
cables in.
Ø
Verify the AC voltage at the dedicated AC outlet. The voltage should always be between
176 ACVrms and 264 ACVrms, at a frequency between 48 Hz and 63Hz.
Ø
Make sure that the AC power switch is in the OFF position (Figure 4-1) and that the Memory
Backup switch is OFF (Figure 2-5).
Ø
Ensure that any option cards and the trunk expansion card (if installed) are firmly inserted.
Ø
Plug the system power cord into the dedicated AC outlet.
Ø
Turn the AC power switch ON.
Ø
Check that the AC LED and the DC LED next to the AC power switch (Figure 4-1) light steady.
Otherwise, check the fuses in the power supply unit as follows:
²
Turn the AC power switch OFF
²
Remove the front cover and the power supply unit cover
²
Check the AC fuses ( 250V 1.6AMP, Figure 4-2). Replace them with spare fuses if they
are blown out. Otherwise, contact your distributor or dealer for advice.
²
Remove the option cards and the trunk expansion card (if installed).
²
Turn the AC power switch ON and check the LED operation again. If the problem is
corrected, you have to replace the option cards or the trunk expansion card with new
cards because at least one of them must be defective. Otherwise, contact your distributor
or dealer for advice.
