The PAM Subsystem’s Role Within the System
MFIOB (Multifunction I/O Board/Ethernet)
The MFIOB is a ServerNet adapter that is integrated into the processor multifunction
(PMF) CRU and the I/O multifunction (IOMF) CRU. The MFIOB provides testing
functions.
FESA (Fast Ethernet ServerNet Adapter)
The FESA is a CRU that supports one Ethernet 10Base-T or 100Base-TX connection
and communicates with multiple processors through its dual ServerNet interfaces to the
ServerNet fabrics.
E4SA (Ethernet 4 ServerNet Adapter)
The E4SA is a CRU that supports four 10Base-T Ethernet connections and
communicates with multiple processors through its dual ServerNet interfaces to the
ServerNet fabrics.
TRSA (Token-Ring ServerNet Adapter)
The TRSA is a CRU that provides connectivity between the server and other nodes on a
token-ring compliant, software-configurable network that has a speed of either 4 or 16
Mbps.
