Four-port 1-Gb/s copper iSCSI I/O module LEDs
The four-port 1-Gb/s copper iSCSI I/O module has three types of status LEDs. Figure 43
shows the LEDs and Table 29 on page 51 describes them.

iSCSI I/O module (labeled 10 GbE iSCSI on
the latch handle) comes with two optical or active Twinax (twisted pair) copper ports, one
power/fault LED, and a link and activity LED for each port (Figure 44 on page 52). The
optical ports on this I/O module can interface at speeds of 10 Gb/s for iSCSI networks.
The two-port 10-Gb/s optical I/O module uses the SFP+ transceiver module (see the
sentences describing the SFP+ in the “Four-port 8-Gb/s FC I/O module” section on

1. The two-port 10-Gb/s I/O module can also use active twinaxial (Twinax) cables. Twinax is a type of
cable similar to coax, but with two inner conductors instead of one. These cables will be supplied
in lieu of the SFP+ when so ordered.
