1. Flash Chips
The flash chip enhances the backplane
memory.
2. Expander Chips
This expander chip allows the backplane
to support dual ports, cascading, and
failover.
3. - 5. SAS Ports
The primary and secondary sets of SAS
ports provide expander features including
cascading and failover. From right to left
the ports are Primary 1,2,3 and Second-
ary 1,2,3.
6. EPP Ports
The EPP ports are used for manufacturer
diagnostic purposes only.
7. Fan Connectors
The 3-pin connectors, designated FAN1,
FAN2, and FAN3, provide power to the
fans. See the table on the right for pin
definitions.
8. Backplane Main Power Connectors
The 4-pin connectors are designated
PWR1, PWR2, PWR3 and PWR4. They
provide power to the backplane. See the
table on the right for pin definitions.
9. Debug Connector
The debug connector is designated EX-
PDBG1 and is used for manufacturer's
diagnostic purposes only.
10. UART Connector
