Replacing a SAS Extender or SAS Expander

This server has two factory-configurable options for hard drive backplane connection: the SAS extender or the SAS expander.

Note The extender and the expander are field-replaceable, but you cannot upgrade an extender to an expander after-factory.

•The extender supports connection for up to eight drives. Connector 1 provides connection for drives 1–4, connector 2 provides connection for drives 5–8. See Supported RAID Controllers and Required Cables, page C-1for the required cables.

•To control more than eight rives, your server must have the optional expander.

The SAS Expander

Note The SAS expander cannot be used with the onboard ICH10R controller. You must use a RAID controller card with the SAS expander.
