This chapter describes how to connect the DES-3225G to your Fast Ethernet network.
Switch to End Node
End nodes include PCs outfitted with a 10, 100 or 10/100 Mbps RJ-45 Ethernet/Fast Ethernet Network Interface Card
(NIC) and most routers. The RJ-45 UTP ports on NICs and most routers are MDI-II. When using a normal straight-through
cable, an MDI-II port must connect to an MDI-X port.
An end node can be connected to the Switch via a two-pair Category 3, 4, 5 UTP/STP straight cable (be sure to use Category
5 UTP or STP cabling for 100 Mbps Fast Ethernet connections). The end node should be connected to any of the twenty-two
ports (1x - 22x) of the DES-3225G or to either of the two 100BASE-TX ports on the front-panel module that came
preinstalled on the switch. An end node should not be connected to an Uplink port (unless using a crossover cable), and if
the top Uplink port is in use, Port 1X must remain vacant; if the bottom Uplink port is in use, Port 2X cannot be used.
Figure 4-1. Switch connected to an End Node
The LED indicators for the port the end node is connected to are lit according to the capabilities of the NIC. If LED
indicators are not illuminated after making a proper connection, check the PC’s LAN card, the cable, switch conditions, and
connections.
The following LED indicator states are possible for an end node to switch connection:
1. The 100M LED indicator comes ON for a 100 Mbps and stays OFF for 10 Mbps.
2. The Link/Act LED indicator lights up upon hooking up a PC that is powered on.
Switch to Hub or Switch
These connections can be accomplished in a number of ways. The most important consideration is that when using a
normal, straight-through cable, the connection should be made between a normal crossed port (Port 1X, 2X, etc.) and an
Uplink (MDI-II) port. If you are using a crossover cable, the connection must be made from Uplink to Uplink, or from a
crossed port to another crossed port.
♦ A 10BASE-T hub or switch can be connected to the Switch via a two-pair Category 3, 4 or 5 UTP/STP straight cable.
