Addresses; Cabling - Bay Networks BayStack 303 User Manual

Addresses

Remember that the BayStack switches each have a MAC station address and an IP
address. The MAC station addresses are unique because each address contains the
Bay Networks manufacturer ID and node ID codes. The switch is shipped with a
default IP address of 000.000.000.000.
It is not required to have a valid IP address for normal switching operation or if
you are managing the switch from a console. However, for management over the
network (SNMP or Telnet session), a valid IP address is required.
You can change the IP address of the unit to match your own network addressing
structures. Ensure that the IP address of the BayStack switch is unique in your
network. The IP address can be changed using the Switch Network Configuration
menu. You will need to set a valid IP address if you intend to use network
management with SNMP or Telnet.

Cabling

Cabling for 10BASE-T networks can consist of 2-pair Category 3, 4, or 5
unshielded twisted pair (UTP) wiring. However, to cover future upgrades to Fast
Ethernet, Bay Networks strongly recommends that you use all Category 5 cable in
your network.
Ethernet 10BASE-T network installations use cables consisting of two pairs of
twisted pair wires—one pair to send data and one to receive data. These wires
must connect to another 10BASE-T station that has the sending pair attached to its
receiving pair and vice versa. In this way, the two nodes can exchange data. If the
two nodes are wired alike, they both attempt to send data out on the same RJ-45
pins. In such a case, a straight-through cable would not work (see
page
normally.
The BayStack switch is designed to have Ethernet NIC cards connect directly to
its RJ-45 ports using straight-through cables. However, if the BayStack switches
need to connect to another hub and that hub follows usual conventions, a
crossover cable is required.
