DIMM handling guidelines
CAUTION:
Failure to properly handle DIMMs can cause damage to DIMM components and the
system board connector.
When handling a DIMM, observe the following guidelines:
•
Avoid electrostatic discharge (on page
15
).
•
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.
•
To align and seat the DIMM, use two fingers to hold the DIMM along the side edges.
•
To seat the DIMM, use two fingers to apply gentle pressure along the top of the DIMM.

Hard drive guidelines
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.
•
Drives in the same logical volume must be of the same type:
o
ACU does not support mixing SAS and SATA drives in the same logical volume.
o
ACU does not support mixing traditional drives and solid state drives (SSD) in the same logical
volume.
SCSI hard drive guidelines
•
Each SCSI drive must have a unique ID.
•
The system automatically sets all SCSI IDs.
•
If only one SCSI hard drive is used, install it in the bay with the lowest number.
