D-8 Front Jumper Location 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 Main Power Connectors
The 4-pin connectors, designated JPW1,
JPW2, and JPW3, 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 Connectors
The primary SAS connectors are designated
PRI-J1 through PRI-J4. The secondary SAS
Ports are designated SED-J1 through SED-
J4 and are not present on EL1 single port
backplanes.
6. - 7. Primary and Secondary UART Con-
nectors
The primary UART connector is designated
PRI-UART and J22. The secondary UART
connector is designated SED-UART and J23
and is not present on BPN-SAS3-826EL1.
UART connectors are used for manufacturer's
diagnostic purposes only.
8. - 9. SDB Connectors
The Primary SDB connector is designated PRI-
SDB and J18. The secondary SDB connector
is designated SED-SDB and J19. (Not present
on BPN-SAS3-826EL1 backplanes) These are
debug connectors used for the manufacturer's
diagnostic purposes only.
