capabilities. 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 are LED indicator possibilities for a PC 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 hookup.
3.
The FDX/Col LED indicator depends upon LAN card capabilities.
Hub to Switch
♦
A 10Base-T hub can be connected to the Switch via a two-pair
Category 3, 4 or 5 UTP/STP straight cable.
♦
A 100Base-TX hub can be connected to the Switch via a two-pair
Category 5 UTP/STP straight cable.
The connection is accomplished from the hub’s uplink (MDI-II) port to any
of the Switch’s (MDI-X) ports 1x - 8x of the DES-3208.
