System Overview 41
•
1
When in FC mode, the SFPs must be qualified 8Gb or 16Gb fiber optic option.
• A 16Gb/s SFP can run at 16Gb/s, 8Gb/s, 4Gb/s, or auto-negotiate its link speed.
• An 8Gb/s SFP can run at 8Gb/s, 4Gb/s, or auto-negotiate its link speed.
•
2
When in 10GbE iSCSI mode, the SFPs must be a qualified 10GbE iSCSI optic option.
•
3
When powering up and booting, iSCSI LEDs will be on/blinking momentarily, then they will
switch to the mode of operation.
•
4
When port is down, both LEDs are off.
CNC iSCSI Controller (2-Port 1Gb RJ-45 SFPs) and LED
Figure 48 provides an illustration of the CNC iSCSI controller (2-port 1Gb RJ-45 SFPs) and LEDs for the
2U12, 2U24, and 5U84 chassis.
NOTE: This CNC controller is used in the QXS-G2-312 and QXS-G2-424.
