Four-port 8-Gb/s FC I/O module LEDs
The four-port 8-Gb/s Fibre Channel (FC) I/O module has two different types of status LEDs.
Figure 41 shows the LEDs and Table 28 describes them.

Four-port 1-Gb/s copper iSCSI I/O module
The four-port 1-Gb/s copper iSCSI I/O module (labeled 1 GbE iSCSI/TOE on the latch
handle) comes with four 1 Gb/s Ethernet Base-T copper ports, one power/fault LED, and a
link and activity LED for each copper port (Figure 42). This iSCSI I/O module can interface
at speeds of 1 Gb/s. The 1 Gb/s Ethernet Base-T copper ports connect to Cat 6 cabling
(see Table 16, “Ethernet cabling guidelines,” on page 34 or Table 21, “Ethernet cabling
guidelines,” on page 40) to an Ethernet switch. This I/O module also includes a TCP
offload engine (or TOE).
