Chapter 1: Overview

Cable Type 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

have a frequency range that extends to 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 have a frequency

range that extends to 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 have a

frequency range that extends to 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.

Disabling Auto-Negotiation on a port and setting the speed and duplex

mode manually also disables the auto-MDI/MDI-X feature. A port where

Auto-Negotiation has been disabled defaults to MDI-X. Disabling Auto-

Negotiation may require manually configuring a port’s MDI/MDI-X setting

or using a crossover cable.

Port Pinouts Refer to Table 12 on page 89 for the port pinouts when a twisted pair port

operates at 10 or 100 Mbps in the MDI configuration and Table 13 on

page 89 for the MDI-X configuration. For port pinouts when a twisted pair

port operates at 1000 Mbps, refer to Table 14 on page 90.
