Figure 19: Removing the Memory DIMM
Step 5 Place the DIMM in an antistatic bag to protect it from ESD damage.
Installing the Memory DIMM
For information about the memory on the router, see the appropriate router documentation. For information
about the memory on the E-Series Server, see the requirements of the installed operating system.
The single-wide E-Series Servers support up to 16 GB of DDR3 memory DIMMs.
The double-wide E-Series Servers support up to 48 GB of DDR3 memory DIMMs.
Performance degradation can occur if you use the following memory configuration:
• Mix DIMM sizes and densities within a channel.
• Partially populate a channel.
• Unevenly populate the DIMMs between CPUs.
DIMMs must be installed in the following order in the double-wide E-Series Servers:
1. DIMM 1 (center DIMM)
2. DIMM 2 (closest to the CPU)
3. DIMM 0 (outboard DIMM)
DIMMs must be installed in the following order in the single-wide E-Series Servers:
1. DIMM 0 (closest to the CPU)
2. DIMM 1 (outboard DIMM)
Before You Begin
Make sure that you connect the wrist-strap clip to an unpainted portion of the chassis frame to channel unwanted
ESD voltages to ground.
