Troubleshooting the Power Supply
To help isolate a power problem:
1. Check the POWER LED.
■ If the POWER LED is off, verify that the power switch is in the on
position.
■ If the power switch is on, unplug the power cord and then plug the power
cord back in.
■ If the POWER LED remains off, continue with the next step.
2. Connect the power cord to another power source if one is available.
■ If the POWER LED comes on, the problem is the first power source.
■ If the POWER LED is off after you connect the power supply to a new
power source, replace the power cord.
■ If the POWER LED still fails to light when the storage router is connected
to a different power source with a new power cord, the power supply is
probably faulty.
3. If you are unable to resolve the problem, contact a customer service
representative for instructions.
