1.9.3 Cables to Use
When connecting between a HBA and a disk drive, use a crossover MiniSAS HD from the
initiator port on the Sierra to MiniSAS HD, and a MiniSAS HD from the target port to
SATAx4, connecting the SATA connector to the disk drive.
1.10 Expandability
The Analyzer provides cascading, external power and other functions through optional
expansion cards on the back panel. You can expand by:
 Cascading with CATC SYNC Expansion Cards
 Using the Power Expansion Card
You can remove expansion cards with two simple tools.
Cascading and Memory Size
For example, you have two units. The first one has 2 GB memory. The second one has
4 GB memory. The system shows the entire memory as 6 GB. If you set buffer size to
6 GB, the system programs the first board for 2 GB and the second board for 4 GB. You
can consider this ratio when you set buffer size to any value. For example, if you set
buffer size to 2 GB, the system programs the first board for (2*2)/6 GB and the second
board for (2*4)/6 GB. Any unit that has more memory will have larger buffer size.
1.10.1 Cascading with CATC SYNC Expansion
You can use cascading of analyzer units for higher port count, by connecting the units
through the optional CATC SYNC Expansion Card on the analyzer back. Using the CATC
SYNC Expansion Cards will not sequentially trigger the State Machine in Advanced mode.
Connecting a Sierra M122 and a Summit T3-16 via the CATC Sync Expansion Card (ACC-
EXP-002-X)
A Sierra M122 and a PCIe Summit T3‐16 are connected using their CATC Sync ports which
require an optional expansion card (ACC‐EXP‐002‐X).
Note: Refer to the relevant protocol analyzer user manual for instructions on how to install the
expansion board.
