10/100 Fast Ethernet Ports

You can set the 10/100 ports on the switch to operate in any combination of half duplex, full duplex, or

10 or 100 Mb/s. You can set the ports for speed and duplex autonegotiation. The default setting is

autonegotiate.

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).

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.

Chapter 1 Product Overview

Cable Side

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 Category

5, Category 5e, or

Category

6 unshielded twisted pair (UTP) cable. The 10BASE-T traffic can use Category 3 or

Category 4 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 the “Connecting Devices to the

Ethernet Ports” section on page 2-25 and the “Connector and Cable Specifications” section on page B-1.

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.

SFP Module Patch Cable

The switch uses an SFP-module patch cable, a 0.5-meter, copper, passive cable with SFP module

connectors at each end (see Figure 1-3). The patch cable connects two switches in a cascaded

configuration.

Figure 1-3 SFP-Module Patch Cable

See the “Inserting and Removing the SFP Module Patch Cable” section on page 2-21 for information

about using the SFP module patch cable.

You can order this cable (part number CAB-SFP-50CM=).

Power-Input Terminal

The power-input terminal provides screw terminals for the AC and DC power connections. The switch

can operate with one or two power supplies. If one of the power sources fail, the other continues to power

the switch. See

Chapter 3, “Power Supply Installation,” for information.

Figure 1-4 Power-Input Terminal

Alarm Ports

The switch has four alarm inputs and one alarm output. The alarm setting is open or closed.

• Open means that the normal condition has current flowing through the contact (referred to as a

normally closed contact). The alarm is generated when the current stops.

• Closed means that no current flows through the contact (referred to as a normally open contact). The

alarm is generated when the current flows.

Alarm Input

The alarm input is a dry-contact alarm port. You can connect up to four alarm inputs from devices, such

as a door, a temperature gauge, or a fire alarm, to the alarm port. You can use the CLI to set the alarm

severity to minor, major, or critical. An alarm generates a system message and turns on an LED. See the

“Alarm LEDs” section on page 1-9 for the LED descriptions.

Alarm Output

The alarm output can be configured as a minor or major alarm. Output alarms often control an external

alarm, such as a bell or a light. To connect an external alarm device to the relay, you connect two relay

contact wires to complete the electrical circuit. See

Figure B-4 on page B-3 for information on the alarm

pinouts.

Management Ports

You can connect the switch to a PC running Microsoft Windows or to a terminal server through either

the RJ-45 console port or the USB console port.

• RJ-45 console port. The RJ-45 connection uses an RJ-45-to-DB-9 female cable.

• USB mini-Type B console port (5-pin connector). The USB connection uses a USB Type A-to-5-pin

mini-Type B cable.

The USB console interface speeds are the same as the RJ-45 console interface speeds.

To use the USB console port, you must install the Cisco Windows USB device driver on the device that

is connected to the USB console port (device running with Microsoft Windows).

Note For information about downloading the Cisco USB device driver, see the “Installing the Cisco Microsoft

Windows USB Device Drivers” section on page C-4.

With the Cisco Windows USB device driver, connecting and disconnecting the USB cable from the

console port does not affect Windows HyperTerminal operations. Mac OS X or Linux require no special

drivers.

Note The 5-pin mini-Type B connectors resemble the 4-pin mini-Type B connectors. They are not compatible.

Use only the 5-pin mini-Type B. See Figure 1-5.

Figure 1-5 USB Mini-Type B Port

The configurable inactivity timeout reactivates the RJ-45 console port if the USB console port is

activated, but no input activity occurs on it for a specified time period. When the USB console port

deactivates due to a timeout, you can restore its operation by disconnecting and reconnecting the USB

cable. For information on using the CLI to configure the USB console interface, see the switch software

guide.
