Always hold DIMMs by the side edges only.

Avoid touching the connectors on the bottom of the DIMM.

Never wrap your fingers around a DIMM.

Avoid touching the components on the sides of the DIMM.

Never bend or flex the DIMM.

When installing a DIMM, observe the following guidelines:

Before seating the DIMM, align the DIMM with the slot.

SAS and SATA hard drive guidelines

When adding hard drives to the server, observe the following general guidelines:

The system automatically sets all drive numbers.

If only one hard drive is used, install it in the bay with the lowest drive number.

Drives must be the same capacity to provide the greatest storage space efficiency when drives are

grouped together into the same drive array.

NOTE:

ACU does not support mixing SAS and SATA drives in the same logical volume.
