SwitchBlade x3112 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 802.3ab 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.
Refer to Table 14 on page 102 for the port pinouts when a twisted-pair port operates at 10 or 100 Mbps in the MDI configuration and Table 15 on page 102 for the MDI-X configuration. For port pinouts when a twisted-pair port operates at 1000 Mbps, refer to Table 16 on page 103.
