Product Description
MDI/MDI-X Port 8
Port 8 is associated with the MDI function.
Port 8 gives you the flexibility of using a straight-through cable to connect to a hub or
another switch (Port 8 MDI), or to any DTE device (Port 8 MDI-X), such as an end station
or a server.
Use only one Port 8, either Port 8 MDI or Port 8 MDI-X.

Power Supply
The switch uses a universal internal switching power supply with 100 to 120 VAC, or 200 to
240 VAC, 50/60 Hz input rating.
Auto-Negotiation
Auto-negotiation is an optional function of the IEEE 802.3u Fast Ethernet standard that
enables devices to automatically exchange information over a link about their speed and
duplex abilities. This allows the devices to perform automatic configurations to achieve the
maximum common level of operation over a link.
The eight (RJ45) 10Base-T/100Base-TX ports on the switch use auto-negotiation for speed
and duplex settings. This means these ports automatically adapt to the wire speed (10 or 100
Mbps) and duplex transmission (half- or full-duplex) supported by the link without user
reconfiguration. Port 9 (fiber) is a 100Base-FX port that always operates at 100 Mbps, and
full-duplex transmission mode.
