2. Remove the server cover.
For instructions on removing the server cover, refer to your server’s service
manual.

Indicator LEDs” on page 39 .
Note – The server must be in standby power mode for viewing the internal LEDs.
You can hold down the Locate button on the server back panel or front panel for
5 seconds to initiate a “push-to-test” mode that illuminates all other LEDs both
inside and outside of the chassis for 15 seconds.

5. Verify that all cable connectors inside the system are firmly and correctly
attached to their appropriate connectors.
6. Verify that any after-factory components are qualified and supported.
For a list of supported PCI cards and DIMMs, refer to your server’s service
manual.
7. Check that the installed DIMMs comply with the supported DIMM population
rules and configurations, as described in “DIMM Population Rules” on page 11 .
