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.
To install a DIMM on 4U server models with non-hot-swap power supplies,
complete the following steps. For the 5U server model with hot-swap power
supplies, please see the next sub-section.
