Attention: Static electricity that is released to internal server components
when the server is powered-on might cause the server to halt, which might
result in the loss of data. To avoid this potential problem, always use an
electrostatic-discharge wrist strap or other grounding system when you work
inside the server with the power on.
2. Remove the server cover (see "Removing the cover and bezel" on page 30).
3. Make sure that the memory hot-swap enabled LED is lit. If the LED is not lit,
enable memory mirroring (see "Active Memory" on page 43).
