C-8 Front Jumper Locations and Settings
Explanation of Jumpers
To modify the operation of the backplane,
jumpers can be used to choose between
optional settings. Jumpers create shorts
between two pins to change the function
of the connector. Pin 1 is identified with
a square solder pad on the printed circuit
board. Note: On two pin jumpers, "Closed"
means the jumper is on and "Open" means
the jumper is off the pins.

3. Backplane Power Connectors
The 4-pin connectors, designated PWR1 -
PWR6 provide power to the backplane. See the
table on the right for pin definitions.
1. - 2. Primary and Secondary Expander Chips
The primary and secondary expander chips
allow the backplane to support dual port, cas-
cading, and failover configurations.
4. - 5. Primary and Secondary SAS Ports
The primary SAS connectors are designated
J49 and J50. The secondary SAS Ports are
designated J51 through J52 and are not pres-
ent on EL1 single port backplanes.
6. - 7. Primary and Secondary UART Con-
nectors
The primary UART connector is designated
PRI-UART and J30. The secondary UART
connector is designated SEC-UART and J24
and is not present on BPN-SAS3-846EL1.
UART connectors are used for manufacturer's
diagnostic purposes only.
8. - 9. SDB Connectors
The Primary SDB connector is designated PRI-
SDB and J31. The secondary SDB connector
is designated SEC-SDB and J29. (Not present
on BPN-SAS3-846EL1 backplanes) These are
debug connectors used for the manufacturer's
diagnostic purposes only.
