Power Consumption: 8 watts typical, 10 watts max.
Network Cable Connectors -
for eight RJ-45 shielded female ports and 1 fiber port
100Mbps: Category 5 UTP/STP, fiber (50/125, 62.5/125, 9/125 micron)
10Mbps: Category 3, 4, 5 UTP (Note: auto-sensing does not sense cable type)
Maximum Load per port: 60 mA
Up-Link, Port # 1 SW
Port 1SW (switched RJ-45) has a manual crossover (MDIX up-link) switch for
connection to a central switch or to another DS80F, DS80C (or equal) unit.
Manual Switch
DS80C: “FF” or “A” switch
Port 2SW (a switched port) has a “FF-A” manual switch. In the “FF” position, it
fixes port 2 at Full 100Mb. In the “A” position, port 2 is set at auto-negotiation
DS80F: “F” or “H” switch
Ports
1SW and 2SW (the switched ports) have a common “F-H” manual switch.
In the “F” position, it causes full-duplex mode to be advertised for the standard
802.3u auto-negotiation session on port 1SW. For fiber, it forces full-duplex
mode at 100Mb. In the “H” position, it causes half-duplex mode to be advertised
for auto-negotiation, and for fiber it forces half-duplex mode.
