AT-GS950/8POE Gigabit Ethernet WebSmart Switch Installation Guide
The cabling requirements for a 10/100/1000Base-T port are:
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.
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.
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.
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 feature 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 system software.
Refer to Table 8 on page 65 for the port pinouts when a twisted pair port operates at 10 or 100 Mbps in the MDI configuration and Table 9 on page 65 for the MDI-X configuration. For port pinouts when a twisted pair port operates at 1000 Mbps, refer to Table 10 on page 66.
