Troubleshooting rx3600 SBA
The rx3600 server shares a common I/O backplane that supports a total of 10 PCI slots. Slots 1-2
on rx3600 systems with only one core I/O SAS card are for customer use. Slots 2-10 are used for
core I/O functions on rx3600 systems with only 1 SAS core I/O card. The System Bus Adapter
(SBA) logic within the zx2 chip of a rx3600 server uses 16 rope interfaces to support up to eight
Lower Bus Adapter (LBA) chips. Each LBA chip interfaces with the SBA in the zx2 chip through
one or multiple rope interfaces as follows:
• One LBA chip uses a single rope interface (used by core I/O) to support a single 32-bit/33-MHz
PCI slot
• Three LBA chips use a single rope interface (one used by core I/O and two are for customer
use) to support dual 64-bit/66-MHz PCI-X slots
• Two LBA chips use dual rope interfaces (both are for customer use) to support two single
64-bit/133-MHz PCI-X slots
• Two LBA chips use two quad rope interfaces (both are for customer use) to support two
single 64-bit/266-MHz PCI-X slots
System Power (BPS and I/O VRM)
The two bulk power supply CRUs in the rx3600 chassis provide N+1 redundancy. Each power
supply CRU is identified as 0 and 1 for logging purposes only. There are no LEDs on the diagnostic
LED panel for the power supplies.
