DES-2218 Ethernet Switch User’s Guide
Making Network Connections
19
Ports 1 through 4 are NWay 10/100Mbps ports. When you connect a station
to one of these ports, the corresponding port Link/Act LED should light. For
100Mbps connections, the corresponding 100M LED indicator should also
light.
When connecting to a hub or an Ethernet switch with an MDI-X port, you
can use a crossover cable, or you can directly use the Uplink port. You can
connect the uplink port directly to a 100BASE-TX Ethernet hub or switch
using straight-through cable.
NOTE:
Port 1 and the Uplink port are MDI-X and MDI
versions of the same port. If you are using the
Uplink port, you cannot use Port 1, and vice
versa.
MII Connection
The switch’s back panel features an industry-standard MII connector,
allowing you to attach transceivers for other types of 100BASE-X media,
such as 100BASE-FX or 100BASE-T4.
To connect a device using the switch’s MII port,
1. Make sure that the switch is turned off whenever connecting a
transceiver to the MII port (or when removing it).
2. Set the transceiver’s address setting to 2, if it has one. (The MII port
is shared with the switch’s port 2).
3. Attach the transceiver to the MII port at the rear of the switch.
4. Power on the switch. If there is a good link through the transceiver
connected to the MII port, both the MII-II LED and the Link/Act LED
for port 2 should light.
