Table 6 provides companion data for Figure 49 above relative to LED states for A/B/C SAS port
expansion.
IMPORTANT:
RAID and expansion chassis configurations:
•
When the expansion IOM shown above ( Figure 49 ) is used with the QXS-G2-412, QXS-G2-424 and
QXS-G2-484 system controller modules for adding storage, its middle HD mini-SAS expansion port
(“B”) is disabled by the firmware.
•
The Ethernet port on the expansion IOM is not used in RAID and expansion chassis configurations,
and is disabled.
Drive Modules
The QXS-G2-312, QXS-G2-324, QXS-G2-412, QXS-G2-424, and QXS-G2-484 systems support
different drive modules for use in 2U and 5U chassis. The drive modules used in 2U chassis are
referred to as drive carrier modules, whereas those used in 5U chassis are referred to as a Disk Drive in
Carrier (DDIC).
