3 T R OUBLESHOOTING Solving EPS Problems If the LED s on the EPS i ndicate a pro b lem, see T able 6 for some su ggested solutions. Ta b l e 6 Solving EPS Pr oblems Prob lem Possible Cause Suggested Acti on A Power LED does not light, and you hav e NO exter nal DC volt age supply.
28 C HAPTER 3: T ROUBLESHOOTING A Power LED does not light, a nd you h ave both AC power and an exter nal DC volt age supply. Both AC po wer and DC power supplies are faulty. ■ Disconne c t the DC power s upply, and us e the procedure s outlin ed earlier in this table to check for problem s with th e AC supp ly.
Solvi ng EPS Problems 29 The device was conne cted too soon after bein g disconn ected. ■ If th e cable s do not appear to be a problem , and pins 4, 5, 7, a nd 8 ar e not ground ed, the end de v ice m ay have been plugge d in too soon after being u nplugged, whic h can result in the d evice ap peari ng to the EP S as a nonpowere d device.
