D6020 does not power up
Symptom
The D6020 will not power up. There are several items to inspect to determine the problem.
Action
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 Rear panel components).
b. Verify that the Power On/Standby button was pressed firmly and held for approximately three seconds.
3. Ensure that the power supplies are working properly.
4. Verify the status by inspecting the power supply LEDs (see Rear panel components).
5. Remove all AC power cords from enclosure power supplies, and reinsert them.
6. Restart the system (see Powering up the D6020 and Powering down the D6020).
7. Inspect the D6020 for the following normal power-up sequence to verify 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.
7-segment display status codes and actions
The 7-segment display shows two types of codes:
•
Enclosure numbers–The enclosure number is shown only as a numeric value.
•
Alarms–Alarms are shown as both an alpha and numeric combination (for example, A3).
Typically, the enclosure number and any alarms are alternately displayed. If more than one issue occurs, multiple codes
can be alternately displayed one after the other.
If the Global Service Indicator (GSI) LED is amber, activate the associated drawer UID button to view the GSI error codes
on the rear display. The two UID buttons are used to select which drawer is displayed. The display cycles a drawer pointer
("|-" points left and "-|" points right), followed by one or more GSI error codes.
