Two-port 10-Gb/s optical I/O module
The two-port 10-Gb/s optical or active Twinax I/O module (labeled 10 GbE v3 on the latch
handle) comes with two optical or ports, one power/fault LED, and a link and activity LED
for each port (Figure 50). The optical ports on this I/O module can interface at speeds of
10 Gb/s. The two-port 10-Gb/s optical I/O module uses the SFP+ transceiver module. For
more information about SFP modules, see the sentences describing the SFP+ in the
“Four-port 8-Gb/s FC I/O module” section on page 47. The two-port 10-Gb/s optical I/O
module uses the SFP+ transceiver module, hence the required SFP+ transceiver module
uses a different part number (for part number label location, see the
VNX5500 Parts
Location Guide
).
Note: This I/O module requires software release VNX OE for File 7.1 to function properly.
Consequently, you cannot mix this I/O module (version 3) with the two-port 10-Gb/s
optical or active Twinax I/O module (version 2) as described in the “Two-port 10-Gb/s
optical I/O module” section on page 64. If you replace a version 2 two-port 10-Gb/s
optical or active Twinax I/O module that only functions in VNX OE for File 7.0 with a version
3 two-port 10-Gb/s Ethernet I/O module, you must replace all of the version 2s of the
two-port 10-Gb/s Ethernet optical or active Twinax I/O modules with version 3s of the
two-port 10-Gb/s Ethernet I/O module that function in VNX OE for File 7.1. To determine
the correct version number, look at the label on the latch handle. It will say either v2 or v3
along with the name of the I/O module on the label. Also, refer to the
VNX5500 Parts
Location Guide
for the location of the part number label.
