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.
