Maximum Distance
Each twisted pair port has a maximum operating distance of 100 meters
(328 feet).
Auto MDI/MDI-X
All of the twisted pair ports on the switch are auto-MDI and IEEE 802.3ab-
compatible. The ports use the auto-MDI feature 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.
LEDs
The system and port LEDs on the front panel of the AT-FS708 switch
display status information. Each port has three LEDs.
Table 1 describes the system and port LEDs on the AT-FS708 Fast
Ethernet switch.
AC Power
Connector
The AT-FS708 Fast Ethernet switch has a single AC power supply socket
on the back panel, which has an auto-switch AC input. Refer to Appendix
A, “Technical Specifications” on page 34, for the input voltage range.
To power ON or OFF the switch, you connect or disconnect the power
cord.
