Troubleshooting Information
PROBLEM SOLUTION
LS10 will not power ON
Press and release the power button on the front panel. If the unit will
not power up, be sure that the rear panel power switch is ON and that
the unit is plugged into a working AC outlet protected by a surge
protector. See
Powering ON the LS10 Processor
, page 16.
If the LS10 is mounted in a rack and a breaker is used for the rack,
make sure the breaker is ON.
Verify the surge protector is powered and is working.
Try changing the LS10 power cord.
If power is getting to the LS10 but it still will not power ON, maybe a
fuse has blown and/or the input voltage setting is incorrect. See section
2.4 for more information or call a qualified installer to check it.
