5Hardware options installation
Introduction
If more than one option is being installed, read the installation instructions for all the hardware options and identify similar steps to streamline the installation process.
WARNING! To reduce the risk of personal injury from hot surfaces, allow the drives and the internal system components to cool before touching them.
CAUTION: To prevent damage to electrical components, properly ground the server before beginning any installation procedure. Improper grounding can cause electrostatic discharge.
Memory options
IMPORTANT: This server does not support mixing LRDIMMs, RDIMMs, UDIMMs, or HDIMMs. Attempting to mix any combination of these DIMMs can cause the server to halt during BIOS initialization.
The memory subsystem in this server can support LRDIMMs, RDIMMs, UDIMMs, or HDIMMs:
●UDIMMs represent the most basic type of memory module and offer lower latency in one DIMM per channel configurations and (relatively) low power consumption, but are limited in capacity.
●RDIMMs offer larger capacities than UDIMMs and include address parity protection.
●LRDIMMs support higher densities than single- and
●HDIMMs provide faster speeds than other DIMMs. 12 DIMMs per processor are required with HDIMMs.
All types are referred to as DIMMs when the information applies to all types. When specified as LRDIMM, RDIMM, UDIMM, or HDIMM, the information applies to that type only. All memory installed in the server must be the same type.
The server supports the following DIMM speeds:
●Single- and
●Single- and
●Single- and
●Single- and
