Table
7 shows the pin-number assignments for the 68-pin
SCSI connectors.
Ethernet port:
The system board in the Netfinity 5600
server contains an Ethernet
controller
.
The controller has
an external RJ-45 connector on the rear of the server that
is used with a category 3, 4, or 5 unshielded twisted-pair
(UTP) cable.
The connector enables an Ethernet network
to attach to the internal transceiver in the server.
Note
The 100BASE-TX Fast Ethernet standard requires that
the cabling in the network be Category 5 or higher.
See “Configuring the Ethernet controller” on page
45 for
additional information about the Ethernet controller.
