Product Overview
Cable Side
When set for autonegotiation, the switch determines the speed and duplex settings of the attached device and advertises
its own capabilities. If the connected device also supports autonegotiation, the switch negotiates the best connection
(the fastest line speed that both devices support and full-duplex transmission if the attached device supports it) and
configures itself accordingly. In all cases, the attached device must be within 328 feet (100 meters).
10/100/1000BASE-T Copper SFP Module Uplink Slots
The IEEE 802.3 1000BASE-T SFP module slots provide full-duplex 1000BASE-T connectivity over copper wire. These
ports use a copper SFP transceiver module that accepts an RJ-45 connector. See
type and length. See
PoE Ports
Warning: Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if interconnections
are made using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such interconnection
methods, unless the exposed metal parts are located within a restricted access location and users and service
people who are authorized within the restricted access location are made aware of the hazard. A restricted access
area can be accessed only through the use of a special tool, lock and key or other means of security. Statement

The 10/100 PoE ports on the Cisco IE-3010-16S-8PC switches provide PoE support for devices that are compliant with
IEEE 802.3af. The Cisco prestandard PoE is also supported for Cisco IP Phones and Cisco Aironet Access Points. The
PoE ports on the switch deliver up to 15.4 W of PoE. Any four of the eight ports are designated as high priority PoE ports,
while the other four ports are designated as low priority PoE ports. When both the power-supply modules are installed,
the system has enough power to support all eight ports as PoE ports. In case one of the power-supply modules fails, the
power to the low priority PoE ports is dropped, while power to the high priority PoE ports remains uninterrupted.
On a per-port basis, you control whether or not a port automatically provides power when an IP phone or an access point
is connected.
The 10/100 PoE ports use RJ-45 connectors with Ethernet pinouts. The maximum cable length is 328 feet (100 meters).
The 100BASE-TX and 1000BASE-T traffic requires CA5, CAT5e, or CAT6 unshielded twisted pair (UTP) cable. The
10BASE-T traffic can use CAT3 or CAT4 UTP cable.
For information about configuring and monitoring PoE ports, see the switch software configuration guide on Cisco.com.
For information about port connections and port specifications, see
and Connector and Cable Specifications, page
Note: The output of the PoE circuit has been evaluated as a Limited Power Source (LPS) per IEC 60950-1.
Dual-Purpose Ports
You can configure the dual-purpose ports on the switch as either 10/100/1000 ports or as SFP-module ports. You can
set the 10/100/1000 ports to autonegotiate, or you can configure them as fixed 10, 100, or 1000 Mb/s (Gigabit) Ethernet
ports.
By default, the switch selects the medium for each dual-purpose port (10/100/1000BASE-T or SFP). When a link is
achieved on one media type, the switch disables the other media type until the active link goes down. If links are active
on both media, the SFP-module port has priority, but you can use the media-type interface configuration command to
manually designate the port as an RJ-45 port or an SFP port.
You can configure the speed and duplex settings consistent with the selected media type. For information on configuring
interfaces, see the switch software configuration guide.
