Cable Type The cabling requirements for a 10/100/1000Base-T port are:
ˆ For 10 Mbps operation: Standard TIA/EIA 568-B-compliant Category 3
or better shielded or unshielded cabling with 100 ohm impedance and
a frequency of 16 MHz.
ˆ For 100 Mbps operation: Standard TIA/EIA 568-A-compliant Category
5 or TIA/EIA 568-B-compliant Enhanced Category 5 (Cat 5e) shielded
or unshielded cabling with 100 ohm impedance and a frequency of 100
MHz.
ˆ For 1000 Mbps operation: Standard TIA/EIA 568-A-compliant
Category 5 or TIA/EIA 568-B-compliant Enhanced Category 5 (Cat 5e)
shielded or unshielded cabling with 100 ohm impedance and a
frequency of 100 MHz.
Auto-MDI/
MDI-X
The twisted pair ports on the switch are IEEE 802ab-compliant and feature
auto-MDI/MDI-X. This feature, available when a port’s speed and duplex
mode are set through Auto-Negotiation, automatically configures a switch
port to MDI or MDI-X depending on the wiring configuration of the port on
the end node. This allows you to connect any network device to a port on
the switch using a straight-through twisted pair cable.
If Auto-Negotiation is disabled on a port and the speed and duplex mode
are set manually, the auto-MDI/MDI-X feature is also disabled and the
port’s wiring configuration defaults to the MDI-X setting. This setting can
be configured with the AlliedWare Plus
TM Operating System Software.
Port Pinouts
Refer to Table 10 on page 67 for the port pinouts when a twisted pair port
operates at 10 or 100 Mbps in the MDI configuration and Table 11 on
page 67 for the MDI-X configuration. For port pinouts when a twisted pair
port operates at 1000 Mbps, refer to Table 12 on page 68.
