This chapter describes how to connect the DES-1210G 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 eight ports (1x - 8x) of the DES-1210G. Port 1x is
an uplink port if the MDI-X/MDI-II button is pushed in. An end node should not be connected to
the uplink port unless using a crossover cable.
Figure 4-1. Switch connected to an End Node
The green Link/Act LEDs for each UTP port will be lit only if the link is successful. The LED on
the right side of the port indicates port speed, it will be lit for 100 Mbps connections, otherwise it
will remain dark. A blinking LED on the left side indicates activity in that port.
