6.2 Checking the power supply

If the POWER LED in the front of the power supply module does not light after power

ON, check the following points :

85 to 264Vac

Note: After eliminating

the cause of the

blown fuse, replace it.

See the following

NOTE.

The problem lies in the

power supply module or

the base.

Make to total current

consumption of the

CPU and I/O come

within the allowable range.

The module mounted

immediately before the

light goes out is defective.

NOTE

1. When carrying out the above checks, always check each step after switching the power supply

OFF again.

2. When a fuse has blown, always determine the cause of the blown fuse and eliminate it. If the

fuse is replaced and the power supply is switched ON again without eliminating the cause,

there is a risk of progressive damage to the module.

When the cause of the blown fuse cannot be determined, consult Toshiba without replacing

the fuse.
