An error occurred that is not represented by a
light path diagnostics LED. Check the event
log for information about the error.
Replace the battery, as described in "Removing
the battery" on page 51 and "Installing the
battery" on page 52.
1. Verify that the DIMM indicated by the lit
LED is a supported memory module, as
described on the ServerProven website.
2. Replace the DIMM indicated by the lit
LED, as described in "Removing a DIMM"
on page 44 and "Installing a DIMM" on
page 46.
Note: Multiple DIMM LEDs do not
necessarily indicate multiple DIMM failures. If
more than one DIMM LED is lit, replace one
DIMM at a time until the error goes away.
Replace the disk drive or solid-state drive. See
"Removing a SAS hard disk drive" on page 36
or "Removing a SATA solid-state drive" on
page 42.
Replace the solid-state drive. See "Removing a
SATA solid-state drive" on page 42.
1. Make sure that the network adapter is
supported.
2. Replace the network adapter, as described
in "Removing a network adapter" on page
49 and "Installing a network adapter" on
page 50.
