7 Troubleshooting the system
If the D6020 does not power up
If the D6020 does not power up:
1. Ensure that the D6020 is connected to a working AC source.
2. Ensure that the power source is working properly:
a. Check the status using the system power LED on the rear panel (see “Understanding
rear panel components” (page 35)).
b. 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 (see “Understanding rear panel components”
(page 35)).
4. Remove all AC power cords from enclosure power supplies, and reinsert them.
5. Restart the system (see “Powering up” (page 18) and “Powering down” (page 18)).
6. Check the D6020 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.
