The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant

to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial

environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause

harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required

to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not

installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to

comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable

protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital

devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television

communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its

peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits

controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

10/100 PoE+ Ports

The ports provide PoE+ support for devices compliant with IEEE 802.3af, IEEE 802.3at, and ePoE and

also provide Cisco prestandard PoE support for Cisco IP Phones and Cisco Aironet Access Points.

The maximum switch power output is either 740 W or 370 W, depending on the switch model. Intelligent

power management allows flexible power allocation across all ports.

For switches with a 740 W power budget, you can budget the PoE and PoE+:

• 15.4 W of PoE output on all ports

• 30 W of PoE+ on 24 ports

For switches with a 370 W power budget, you can budget the PoE and PoE+:

• 15.4 W of PoE output on 24 ports

• 7.7 W of PoE output on 48 ports

• 30 W of PoE+ on 12 ports

• Total power budget can be allocated among the ports

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 10BASE-T and 100BASE-TX 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 port connections and port specifications, see the “10/100 and 10/100/1000 Port

Connections” section on page 2-26 and Appendix B, “Connector and Cable Specifications.”

Management Ports

• Ethernet management port

• RJ-45 console port (EIA/TIA-232)

• USB mini-Type B console port (5-pin connector)

You can connect the switch to a host such as a Windows workstation or a terminal server through the

Ethernet management port, the RJ-45 console port, or the USB console port (USB mini-Type B port).

The 10/100 Ethernet management port connection uses a standard RJ-45 crossover or straight-through

cable. The RJ-45 console port connection uses the supplied RJ-45-to-DB-9 female cable. The USB

console port 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.

If you use the USB console port, the Cisco Windows USB device driver must be installed on any PC

connected to the console port (for operation with Microsoft Windows).

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

Windows USB Device Driver” section on page C-3.

With the Cisco Windows USB device driver, you can connect and disconnect the USB cable from the

console port without affecting Windows HyperTerminal operations. Mac OS X or Linux require no

special drivers.

The console output always goes to both the RJ-45 and the USB console connectors, but the console input

is active on only one of the console connectors at any one time. The USB console takes precedence over

the RJ-45 console. When a cable is connected into the USB console port, the RJ-45 console port becomes

inactive. Conversely, when the USB cable is disconnected from the USB console port, the RJ-45 port

becomes active.

Note The 4-pin mini-Type B connectors resemble 5-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

You can use the command-line interface (CLI) to configure an inactivity timeout which reactivates the

RJ-45 console if the USB console has been activated and no input activity has occurred on the USB

console for a specified time period.

After the USB console deactivates due to inactivity, you cannot use the CLI to reactivate it. Disconnect

and reconnect the USB cable to reactivate the USB console. For information on using the CLI to

configure the USB console interface, see the switch software guide.

USB Type A Port

The USB Type A interface provides access to external USB FLASH devices (also known as thumb drives

or USB keys).

The interface supports Cisco USB flash drives with capacities from 64 MB to 1 GB.

Cisco IOS software provides standard file system access to the flash device: read, write, erase, and copy,

as well as the ability to format the flash device with a FAT file system.

For more information about the switch management ports, see the switch software configuration guide

and the command reference on Cisco.com and the

“Connector and Cable Specifications” section on

page B-1.

SFP and SFP+ Module Slots

The switch has either two or four 1-Gigabit SFP or two 10-Gigabit SFP+ module slots. The slots marked

SFP+ support both SFP and SFP+ modules. The SFP slots support only the SFP modules.
