366 Power-Up Troubleshooting
Power-Up Troubleshooting
When the disk array is powered up, each component perform an internal self-test, to ensure
it is operating properly.
Visual indications of power-up are:
• The green Power LED on the controller enclosure is on
• The green Power LED on each disk enclosures is on
• All fans are operating
• No Fault LEDs are on. See Figure 92 on page 368 and Figure 93 on page 377 .
The following LEDs will also be on:
• Controller enclosure:
– The green Full Charge LEDs on the controller batteries, if the batteries are fully
charged. If the batteries are not fully charged, the Full Charge LEDs will flash until
charging is complete, and then remain on.
– The Power LEDs on the controller enclosure
• Disk enclosure
– The green Power Supply LEDs
– Fan LEDs
If the power-up sequence fails, the appropriate amber Fault LED will be on, identifying the
failing component. If the power-up tests fail, all modules in the disk array must be
examined for Fault LEDs that are on. See
Table 48 on page 369 and Table 50 on page 377 ).
Note Inserting a module while the power-up tests are running can cause the tests to
fail. Insert all modules and then cycle power to rerun the power-up tests.
