When the MDS600 does not power up
If the MDS600 does not power up:

2. Ensure that the power source is working properly:
o Check the status using the system power LED on the rear panel ("Rear panel LEDs and buttons" on
page 8).
o Be sure that the Power On/Standby button was pressed firmly and held for approximately 3
seconds.
3. Ensure that the power supplies are working properly.
Check the status using the power supply LEDs ("Rear panel LEDs and buttons" on page 8).
4. Remove all AC power cords from enclosure power supplies and reinsert them.
5. Restart the system.
6. Check the MDS600 for the following normal power-up sequence to be sure that the system meets the
minimal hardware requirements and is powered up during normal operations:
a. The rear panel power LED turns from standby (amber) to on (solid green).
b. The system fans spin up to a high speed, and then spin down to a normal operating speed.
