G-1 Overview of the SAS3-216EL1/EL2 Backplanes
The BPN-SAS3-216EL1/EL2 model backplanes consists of a BPN-SAS3-216EB
backplane (X) with one or two BPN-SAS3-216EL daughter cards (Y and Z) mounted
on the rear of the backplane.
The BPN-SAS3-216EL1 model consists of the BPN-SAS3-216EB backplane (X)
and one BPN-SAS3-216EL primary daughter card (Y), mounted on the right-hand
side of the backplane.
The BPN-SAS3-216EL2 model consists of the BPN-SAS3-216EB backplane (X)
with a BPN-SAS3-216EL primary daughter card mounted on the right (Y) and a
BPN-SAS3-216EL secondary daughter card mounted on the left (Z).
Components on the front side of the BPN-SAS3-216EB backplane include twenty-
four SAS connectors and their respecitve activity and failure LEDs. Components on
the rear side of the backplane include jumpers and power connectors. The daughter
card's components include SAS ports, ash and expander chips.
