The LED indicators for PC connection are dependent on the LAN card
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 100 M LED indicator comes on for a 100 Mbps and stays off for
10 Mbps.
2. The Link/Act LED indicator illuminates upon hookup.
3. The FDX/Col LED indicator depends upon LAN card capabilities.
Hub to Switch
A hub (10 or 100Base-T) can be connected to the Switch via a two-pair
Category 3, 4, 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 - 4x for the DES-1004 or 1x - 8x for the DES-1008.
