Connecting to the Management LAN
The SPIO provides two types of interfaces for physical connection to the management LAN: the fiber optic SFP and the
Ethernet (RJ-45) interfaces.
When you cable these interfaces, make sure you do only one of the following:

Both SFP interfaces

Both Ethernet interfaces

SFP 1 and Ethernet 2

SFP 2 and Ethernet 1
Important:
Be sure to label the interface cables with their destination prior to connecting them to the SPIO. This
will assure proper reconnection should the card need to be serviced.
Using the SFP Interfaces
The two optical 1000Base-SX SFP interfaces are hot-pluggable 802.3z-compliant Gigabit Ethernet interfaces that take
their configuration from the inserted cable type. Refer to the following table for information about supported cable
specifications.
