3519 Rack Storage Expansion Enclosure - Power Supply
Applicable to: World-Wide
Note:
Verify that the voltage-select switch is set for the correct voltage. If the voltage switch is set to the wrong position, permanent damage might occur to the rack when you power it on. If the power-on indicator is not on, and the power supply fan is not
running, check the power cord for proper installation and continuity.
If the power cord is OK, either the power supply (fru p/n 60H8301) is defective or a defective device is causing the power supply to shut off. Check the power supply voltages.
The power supply is rated at 200 watts. Too many devices (adapters or hard disk drives) can cause power consumption to exceed 200 watts and cause the power supply to shut down. See "Power Supply Shutdowns." Remove adapters or devices to determine if this is the cause.
If the voltages are incorrect, replace the power supply.

Power Supply Shutdowns
If the power supply shuts down, or appears to fail at power-on, you might have one of the following problems:
- Too many devices are set to start instantly. See "Setting the Motor-Start Jumper" in the PS/2 Hardware Maintenance
Manual.
- There are too many large-capacity devices installed (such as hard disk drives). The nominal operating current of the devices installed collectively exceeds the available current of the power supply. See the "Personal System/2 Installation Planning" guide (form number S41G-2927) for more information.
Also ensure that the fans operate when the machine is powered on.
Note:
Verify that the voltage-select switch (if applicable) is set for the correct voltage.
