1. 4-port 25GbE Optical I/O module
2. 4-port 16Gb Fibre Channel I/O module
3. 4-port 10GbE BaseT I/O module
4. 4-port 12Gb SAS backend I/O module
When adding new I/O modules, always install I/O modules in pairs: one module in SP
assembly A and one module in SP assembly B. Both SP assemblies must have the
same type of I/O modules in the same slots.

4-port 25GbE Optical I/O module
The 4-port 25GbE Optical I/O module is an Ethernet I/O module that is used to serve
Ethernet network traffic and iSCSI block protocol to hosts for the platform. The I/O
module uses an optical 10G or 25G capable SFP+ connection to a host or switch port.
4-port 16Gb Fibre Channel I/O module
The 4-port 16Gb Fibre Channel I/O module comes with four optical ports, one power
and fault LED, and a combination link and activity LED for each optical port. This I/O
module can interface at speeds of 4, 8, and 16 Gb/s FC for host or initiator layered
connections.
4-port 10GbE BaseT I/O module
The 4-port 10GbE BaseT I/O module can interface at speeds of 1 Gb/s and 10 Gb/s
and supports both IP(file) and iSCSI (Block) on the same SP assembly. Ports can be
configured as both IP and iSCSI simultaneously. The I/O module comes with four 10-
Gb/s RJ-45 ports, one power/fault LED, activity LED, and link LED for each port.
