AT-FS708LE/PoE Switch Installation and User’s Guide

compliant. With Auto-Negotiation, the switch automatically matches the 
highest possible common speed between each switch port and each end-
node. For example, if an end-node is capable of only 10 Mbps, the switch 
sets the port connected to the end-node to 10 Mbps.

Duplex Mode

Each twisted pair port on the switch can operate in either half- or full-
duplex mode. The twisted pair ports are IEEE 802.3u-compliant and 
automatically negotiate the duplex mode setting.

Note

In order for the switch to set the duplex mode for each port correctly, 
the end-nodes that you connect to the switch ports also need to be 
configured for Auto-Negotiation. Otherwise, a duplex mode 
mismatch can occur, affecting network performance. For further 
information, refer to “Duplex Mode” on page 15.

Cabling

For 10 Mbps operation, Category 3 or better unshielded twisted pair 
cabling is required. For 100 Mbps operation, Category 5 unshielded 
twisted pair cabling is required.

Auto MDI/MDI-X

All of the twisted pair ports on the switch feature auto-MDI to automatically 
configure themselves as MDI or MDI-X when connected to an end-node. 
Consequently, you can use a straight-through twisted pair cable to 
connect any network device to a port.

PoE Capability

Power over Ethernet (PoE) is a system that supports power along with 
data using a single Ethernet cable.

The four ports of the AT-FS708LE/PoE switch are capable for providing 
power to connected devices. The switch can support four class 2 Powered 
Devices (PDs) or two class 3 PDs at a time. See “Power over Ethernet” on 
page 14.

LEDs

The LEDs on the front panel of the AT-FS708LE/PoE switch display status 
information. Table 1 on page 12 describes the LEDs on the AT-FS708LE/
PoE switch.
