Cisco IE 2000 Switch Hardware Installation Guide
OL-25818-04
Chapter 1 Product Overview
Front Panel
You can use the mdix auto interface configuration command in the command-line interface (CLI) to
enable the automatic medium-dependent interface crossover (auto-MDIX) feature. When the auto-
MDIX feature is enabled, the switch detects the required cable type for copper Ethernet connections and
configures the interfaces accordingly. For configuration information for this feature, see the switch
software configuration guide or the switch command reference.
Power over Ethernet Ports
On certain models of the IE 2000 switch, four of the 10/100BASE-T ports are available as PoE ports.
The four ports can operate as PoE (IEEE 802.3af) ports or can be configured to operate as PoE+
(IE 802.at) ports. Each PoE port requires 15.4 Watts of power while PoE+ requires 30 Watts. A 54VDC
/1.2Amp power source (65W) can support 4 PoE ports or 2 PoE+ ports.
Cable lengths of up to 328 ft (100 m) are supported.
10/100BASE-T Uplink Ports
The IEEE 802.3u 10/100BASE-T uplink ports provide full-duplex 10, 100 Mb/s connectivity over
Category 5 unshielded twisted pair (UTP) copper cabling. The default setting is autonegotiate. The cable
can be up to 100 m (0.1 km) in length.
10/100/1000BASE-T Uplink Ports
The IEEE 802.3u 10/100/1000BASE-T uplink ports provide full-duplex 10, 100 or 1000 Mb/s
connectivity over Category 5 unshielded twisted pair (UTP) copper cabling. The default setting is
autonegotiate. The cable can be up to 100 m (0.1 km) in length.
100 Mb/s SFP Module Uplink Slots
The IEEE 802.3u 100 Mb/s SFP module uplink slots provide full-duplex 100 Mb/s connectivity over
multi-mode (MM) fiber cables or single-mode (SM) fiber cables. These ports use a SFP fiber-optic
transceiver module that accepts a dual LC connector. Check the SFP specifications for the cable type and
length.
100/1000 Mb/s SFP Module Uplink Slots
The IEEE 802.3u 100 Mb/s SFP module uplink slots provide full-duplex 100 or 1000 Mb/s connectivity
over multi-mode (MM) fiber cables or single-mode (SM) fiber cables. These ports use a SFP fiber-optic
transceiver module that accepts a dual LC connector. Check the SFP specifications for the cable type and
length.
Dual-Purpose Fast Ethernet Uplink Ports
You can configure the dual-purpose Fast Ethernet uplink ports on the switch as either 10/100BASE-T
ports or as 100 Mb/s SFP-module ports. You can set the 10/100 ports to autonegotiate, or you can
configure them as fixed 10 or 100 Mb/s ports.
