Cisco Catalyst 3560-CX Istruzioni operative e di sicurezza
Product Overview
The Catalyst 3560-CX and 2960-CX switches are Ethernet switches to which you can connect devices such
as Cisco IP Phones, Cisco Wireless Access Points, workstations, and other network devices such as servers,
routers, and other switches.
You can deploy these switches outside of the traditional wiring closet environment, such as in office
workspaces, hotel rooms, slot machines, kiosks, and classrooms. The switch is suitable for deployments
where there are space and power constraints (access to power outlets).
See the switch software configuration guide for deployment examples.

PoE+ ports 1 to 6 are Gigabit Ethernet 1/0/1 to 1/0/6. The remaining ports are 10-Gigabit Ethernet 1/0/1
and 1/0/2. However, depending on the SFP type, the rightmost ports will either be 10-Gigabit Ethernet
1/0/3 and10-Gigabit Ethernet 1/0/4 or Gigabit Ethernet 1/0/7 and Gigabit Ethernet 1/0/8.
Note
PoE and 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 124 W or 240 W, depending on the switch mode. Intelligent
power management allows flexible power allocation across all ports.
For switches with a 124 W power budget, you can budget the PoE and PoE+:
•15.4 W of PoE output on 8 ports
•30 W of PoE+ output on 4 ports
For switches with a 240 W power budget, you can budget the PoE and PoE+:
•15.4 W of PoE output on 12 ports
•30 W of PoE+ output on 8 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 PoE ports use RJ-45 connectors with Ethernet pinouts. The maximum cable length is 328 feet (100 meters).
The 10BASE-T, 100BASE-TX, 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.
Cisco intelligent power management capabilities include enhanced power negotiation, power reservation, and
per-port power policing. For information about configuring and monitoring PoE ports, see the switch software
configuration guide on Cisco.com.
The output of the PoE circuit has been evaluated as a Limited Power Source (LPS) per IEC 60950-1.Note
10/100/1000 Ports
The 10/100/1000 ports use RJ-45 connectors with Ethernet pinouts. The maximum cable length is 328 feet
(100 meters). The 10BASE-T, 100BASE-TX, 1000BASE-T traffic requires Category 5 or Category 5e twisted
pair (UTP) cable. The 10BASE-T traffic can use Category 3 or Category 4 UTP cable.

PoE and PoE+ Ports
Multigigabit ports
The Multigigabit ports can be configured to auto-negotiate multiple speeds on switch ports, and support 100
Mbps, 1 Gbps, 2.5 Gbps, and 5 Gbps speeds on Category5e cables, and up to 10 Gbps over Category6 and
Category 6A cables.
The Multigigabit ports support PoE and PoE+ for all the supported speeds and cable types. The following
table lists the cable types and speed.

Management Ports
The management ports connect the switch to a PC running Microsoft Windows or to a terminal server.
•RJ-45 console port (EIA/TIA-232). The RJ-45 console port connection uses an RJ-45-to-DB-9 female
cable.
•USB mini-Type B console port (5-pin connector).
If you use the USB mini-Type B console port, the Cisco Windows USB device driver must be installed on
any PC connected to the console port (for operation with Microsoft Windows). Mac OS X or Linux do not
require special drivers.
The 4-pin mini-Type B connector resembles the 5-pin mini-Type B connectors. They are not compatible. Use
only the 5-pin mini-Type B.
This illustration shows a 5-pin mini-Type B USB port.
Figure 3: USB Mini-Type B Port
With the Cisco Windows USB device driver, you can connect and disconnect the USB cable from the console
port without affecting Windows HyperTerminal operations.
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.

Product Overview
Multigigabit ports
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.
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 software guide.
SFP and SFP+ Module Slots
The switch has either two 1-Gigabit SFP or 10-Gigabit SFP+ module slots. The slots marked SFP+ support
both SFP and SFP+ modules. The SFP slots support only the SFP modules.
For Cisco SFP and SFP+ modules documentation, including compatibility matrixes, refer to this URL: http:/

LEDs
You can use the switch system and port LEDs to monitor switch activity and performance.

If you connect a cable to a console port, the switch automatically uses that port for console communication.
If you connect two console cables, the USB-mini console port has priority.
