10BASE-T Ports
The 10BASE-T port connections are provided for the 10 Mb/s Ethernet segment
or nodes to attach to the BayStack 303 and 304 Ethernet Switches. The RJ-45
jacks accept standard Category 3, 4, or 5 copper unshielded twisted pair (UTP)
cable connections. Pin assignments for the standard RJ-45 connector are given in
. The BayStack switches are shipped with the 10BASE-T connectors
configured as MDI-X (media-dependent interface-crossover). These ports connect
over straight cables to the network interface controller (NIC) card in a node or
server, similar to a conventional Ethernet repeater hub. If you are connecting to
another Ethernet hub or Ethernet switch, you need a crossover cable unless an
MDI connection exists on the associated port of the attaching device (see
for a description of the crossover
cable).
The 10 Mb/s ports operate in half-duplex mode only, and each port has an
associated LED that indicates link status of the line.
