10/100/1000Base-T RJ-45 Ports
Depending on the model that you purchased, 8 or 9 10/100/1000Base-T RJ-45 ports
are located on the front panel of the Managed Switch. These RJ-45 ports allow users
to connect their traditional copper-based Ethernet devices to network. All these ports
support auto-negotiation and MDI/MDIX auto-crossover, i.e. the crossover or straight
through CAT-5 cable may be used.
1.2.2 Assigning IP Addresses
IP addresses have the format n.n.n.n, for example 168.168.8.100.
IP addresses are made up of two parts:
The first part (168.168.XXX.XXX in the example) indicates network address identifying
the network where the device resides. Network addresses are assigned by three
allocation organizations. Depending on your location, each allocation organization
assigns a globally unique network number to each network that wishes to connect to
the Internet.
The second part (XXX.XXX.8.100 in the example) identifies the device within the
network. Assigning unique device numbers is your responsibility. If you are unsure of
the IP addresses allocated to you, consult the allocation organization from which your
IP addresses were obtained.
Remember that an address can be assigned to only one device on a network. If you connect
to the outside, you must change all the arbitrary IP addresses to comply with those you have
been allocated by the allocation organization. If you do not do this, your outside
communications will not be connected.
A subnet mask is a filtering system for IP addresses. It allows you to further subdivide your
network. You must use the proper subnet mask for a proper operation of a network with
subnets defined.
