3.2.5 SAS Channels
An external x4 SAS/SATA connector provides access to two of the AT8404 AMC bays, See “Storage Intercon-
nect” on page 23.. The connector is a SFF-8470 fixed (receptacle) shielded connector with jack screws.
A SAS signal conditioner (repeater) and multiplexer is needed to guarantee SAS signal integrity over the cable
between two RTM blades. The maximum SAS cable length between two RTM blades is 4m. SAS links work after
both RTM units have been powered up. SAS port mapping is drawn below:
