10/100 and 10/100/1000 Fast Ethernet Downlink Ports
You can set the 10/100 ports to operate at 10 or 100 Mb/s in full-duplex or half-duplex mode. You can
set the 10/100/1000 ports to operate at 10, 100, or 1000 Mb/s in full-duplex or half-duplex mode. You
can also set these ports for speed and duplex autonegotiation. (The default setting is autonegotiate.)
Automatic medium-dependent interface crossover (auto-MDIX) is a feature that allows the switch
interface to detect the required cable connection type (straight-through or crossover) and automatically
configure the connection appropriately. With auto-MDIX enabled, you can use either a straight-through
or crossover type cable to connect to the other device, and the interface automatically corrects for any
incorrect cabling. In all cases, the attached device must be within 328 feet (100 meters)
The 10/100/1000 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 port connections and port specifications, see the “Connecting to the 10/100 and
10/100/1000 Ports” section on page 2-33.
PoE Ports (Switches with PoE Ports)
The PoE and PoE+ ports provide PoE support for devices compliant with 802.3af and 802.3at and also
provide Cisco prestandard PoE and PoE+ support for Cisco IP Phones and Cisco Aironet Access Points.
All 8 downlink ports on the Catalyst 2960CPD-8PT-L, 2960C-8PC-L, 2960C-12-PC-L, and the
3560CPD-8PT-S and are PoE-capable. Each port can supply 15.4 W of PoE per port.
The maximum switch power output for the Catalyst 2960CPD-8PT-L is 22.4 W, and for the
Catalyst 3560CPD-8PT-S is 15.4 W. The maximum switch power output for the Catalyst 2960C-8PC-L
and the 2960C-12-PC-L is 123.2 W.

Product Overview
Front Panel
All 8 or 12 downlink ports on the Catalyst,3560CG-8PC-S, 3560C-8PC-S, and 3560C-12PC-S switches
are PoE+ capable. The maximum switch power output is 123.2 W. You can budget the PoE and PoE+:
•
15.4 W of PoE output on eight ports
•
30 W of PoE+ on four 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 10/100/1000 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.
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.
For information about port connections and port specifications, see the “Connecting to the 10/100 and
10/100/1000 Ports” section on page 2-33.
Note
The output of the PoE circuit has been evaluated as a Limited Power Source (LPS) per IEC 60950-1.
PoE Pass-Through
The Catalyst 2960CPD-8PT-L and 3560CPD-8PT-S switches provide PoE pass-through. The
Catalyst 2960CPD-8PT-L is powered either through the 10/100/1000 PoE uplink ports receiving power
from a PoE or PoE+ switch or through an auxiliary power adapter. The Catalyst 3560CPD-8PT-S is
powered through the 10/100/1000 PoE uplink ports receiving power from a PoE+ switch or through an
auxiliary power adapter. If the switch has surplus power (see Table 1-2), it can power other PoE-capable
devices such as IP phones, access points, and so on. See Figure 1-6.
See the “Powering the Switch” section on page 2-4 for information on powering the switches.

Depending upon the available PoE budget, these switches can power other PoE-capable devices such as
IP phones, access points, and so on. See Table 1-2 for PoE budgeting information. See Figure 1-6.
For information on powering the switches, see the “Powering the Switch” section on page 2-4.
USB Type A Port
Some models have an USB Type A port. This port provides access to external Cisco USB flash devices
(also known as thumb drives or USB keys). The port 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 capability 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.
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 Modules
The switch Ethernet SFP modules provide connections to other devices. These field-replaceable
transceiver modules provide the uplink interfaces.The modules have LC connectors for fiber-optic
connections or RJ-45 connectors for copper connections.
You can use any combination of these supported SFP modules:
•
GLC-LH-SM=
•
GLC-SX-MM=
•
GLC-ZX-SM=
•
GLC-BX-D=
•
GLC-BX-U=

For information about SFP modules, see your SFP module documentation and the “Installing SFP
Modules” section on page 2-31. For cable specifications, see the “SFP Module Cables” section on
page B-3.
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 mini-Type B console port, also referred to as the USB-mini console
port.
•
RJ-45 console port. The RJ-45 connection uses an RJ-45-to-DB-9 female cable.
•
USB-mini console port (5-pin connector). The USB connection uses a USB Type A-to-5-pin
mini-Type B cable.
The USB-mini console interface speeds are the same as the RJ-45 console interface speeds.
To use the USB-mini console port, you must install the Cisco Windows USB device driver on the device
that is connected to the USB-mini console port and that is running 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 1-7.
USB Mini-Type B Port

Figure 1-7
The configurable inactivity timeout reactivates the RJ-45 console port if the USB-mini console port is
activated, but no input activity occurs for a specified time period. When the USB-mini 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-mini console interface, see the switch
software guide.

Switch Installation
Mounting the Switch
On a Desk or Shelf (without Mounting Screws)
Step 1
Locate the adhesive strip with the rubber feet in the accessory kit.
Step 2
Remove the four rubber feet from the adhesive strip, and attach them to the recessed areas on the bottom
of the unit. This prevents the switch from sliding on the desk or shelf.
Note
Step 3
Warning
We strongly recommend that you attach the rubber feet. Doing so helps prevent airflow
restriction and overheating.
Place the switch on the desk or shelf.
To prevent airflow restriction, allow clearance around the ventilation openings to be at least:
3 in. (7.6 cm) Statement 1076
After you mount the switch, see the “After Installing the Switch” section on page 2-31 for information
about the switch configuration.
Desk, Shelf, or Wall (with Mounting Screws)
You can use the mounting screws to mount the switch:
•
On a desk or a shelf
•
Under a desk or a shelf
•
On a wall
Desk- or Shelf-Mounting
Step 1
Use the screw template to align the mounting screw holes and also as a guide to make sure that you install
the screws into the desk or shelf with proper clearance.
Step 2
Position the screw template on top of the desk or shelf so that the two side-by-side slots face the front of
the desk or shelf, as shown in Figure 2-1. This ensures that the power cord faces the rear of the desk or
shelf after the switch is installed.
Note
Wait before you attach the screw template to the desk or shelf.

ports and cables from contamination and ambient light.
Removing SFP Modules
Step 1
Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.
Step 2
Disconnect the cable from the SFP module. For reattachment, note which cable connector plug is send
(TX) and which is receive (RX).
Step 3
Insert a dust plug into the optical ports of the SFP module.
Step 4
If the module has a bale-clasp latch, pull the bale out and down to eject it. If the latch is obstructed and
you cannot use your finger, use a small, flat-blade screwdriver or other long, narrow instrument.
Step 5
Grasp the SFP module, and carefully remove it from the slot.
Step 6
Place the module in an antistatic bag or other protective environment.

Connecting to the 10/100 and 10/100/1000 Ports
The 10/100 and 10/100/1000 Ethernet 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 UTP cable. The 10BASE-T traffic uses Category 3 or Category 4 cable.
The autonegotiation feature is enabled by default on the switch. At this setting, the switch ports
configure themselves to operate at the speed of the attached device. If the device does not support
autonegotiation, you can set the switch port speed and duplex parameters. To maximize performance,
either let the ports autonegotiate both speed and duplex, or set the port speed and duplex parameters on
both ends of the connection.
See the switch software configuration guide or the switch command reference on Cisco.com for more
information about autonegotiation and auto-MDIX.
If auto-MDIX is disabled, use the guidelines in Table 2-1 to select the cable for connecting the
10/100/1000 Ethernet ports to other devices. See the “Cables and Adapters” section on page B-3 for
cable-pinout descriptions. See Figure 2-36.

Connecting to the PoE Ports
The 10/100 PoE ports have the same autonegotiation settings and cabling requirements as those in the
“Connecting to the 10/100 and 10/100/1000 Ports” section on page 2-33. These ports provide PoE
power.
See the e “PoE Ports (Switches with PoE Ports)” section on page 1-5 for information on the cables and
connectors.
The ports provide PoE support for 802.3af-compliant devices and also provide Cisco prestandard PoE
support for Cisco IP Phones and Cisco Aironet Access Points.
On a per-port basis, you can control whether or not a port automatically provides power to a connected
IP phone or an access point.
To access an advanced PoE planning tool, use the Cisco Power Calculator on Cisco.com:
http://tools.cisco.com/20/launch.jsp
You can use this application to calculate the power supply requirements for a specific PoE configuration.
The results show output current, output power, and heat dissipation.
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

The switch LEDs provide troubleshooting information about the switch. They show POST failures,
port-connectivity problems, and overall switch performance. You can also get statistics from the device
manager, the CLI, or an SNMP workstation. See the software configuration guide, the switch command
reference guide on Cisco.com, or the documentation that came with your SNMP application for details.
Switch POST Results
See the “Verifying Switch Operation” section on page 2-5 for information on POST.

Troubleshooting
Diagnosing Problems
Switch LEDs
Look at the port LEDs information when troubleshooting the switch. See the “LEDs” section on
page 1-12 for a description of the LED colors and their meanings.
Switch Connections
Bad or Damaged Cable
Always examine the cable for marginal damage or failure. A cable might be just good enough to connect
at the physical layer, but it could corrupt packets as a result of subtle damage to the wiring or connectors.
You can identify this problem because the port has many packet errors or it constantly flaps (loses and
regains link).
•
Exchange the copper or fiber-optic cable with a known good cable.
•
Look for broken or missing pins on cable connectors.
•
Rule out any bad patch panel connections or media convertors between the source and the
destination. If possible, bypass the patch panel, or eliminate media convertors
(fiber-optic-to-copper).
•
Try the cable in another port to see if the problem follows the cable.
Ethernet and Fiber-Optic Cables
Make sure that you have the correct cable:
•
For Ethernet, use Category 3 copper cable for 10 Mb/s UTP connections. Use either Category 5,
Category 5e, or Category 6 UTP for 10/100 or 10/100/1000 Mb/s connections.
•
Verify that you have the correct fiber-optic cable for the distance and port type. Make sure that the
connected device ports match and use the same type encoding, optical frequency, and fiber type.
•
Determine if a copper crossover cable was used when a straight-through was required or the reverse.
Enable auto-MDIX on the switch, or replace the cable. See Table 2-1 for recommended Ethernet
cables.
Link Status
Verify that both sides have link. A broken wire or a shutdown port can cause one side to show link even
though the other side does not have link.
A port LED that is on does not guarantee that the cable is functional. It might have encountered physical
stress, causing it to function at a marginal level. If the port LED does not turn on:
•
Connect the cable from the switch to a known good device.
•
Make sure that both ends of the cable are connected to the correct ports.
•
Verify that both devices have power.
•
Verify that you are using the correct cable type. See Appendix B, “Connector and Cable
Specifications” for information.
•
Look for loose connections. Sometimes a cable appears to be seated but is not. Disconnect the cable,
and then reconnect it.

Troubleshooting
Diagnosing Problems
10/100 and 10/100/1000 Port Connections
A port appears to malfunction:
•
Verify the status of all ports. See Table 1-7 on page 1-14 for descriptions of the LEDs and their
meanings.
•
Use the show interfaces privileged EXEC command to see if the port is error-disabled, disabled, or
shut down. Re-enable the port if necessary.
•
Verify the cable type. See Appendix B, “Connector and Cable Specifications.”
10/100 PoE or PoE+ Port Connections
A powered device connected to a PoE or PoE+ port does not receive power:
Caution
•
Verify the status of all the ports. See Table 1-7 for descriptions of the LEDs and their meanings.
•
Use the show interfaces privileged EXEC command to see if the port is error-disabled, disabled, or
shutdown. Re-enable the port if necessary.
•
Verify the cable type. Many legacy powered devices, including older Cisco IP phones and access
points that do not fully support 802.3af might not support PoE when connected to the switch by a
crossover cable. Replace the crossover cable with a straight-through cable.
Noncompliant cabling or powered devices can cause a PoE port fault. Use only compliant cabling to
connect Cisco prestandard IP Phones, and wireless access points, or 802.3af-compliant devices.
SFP Module
Use only Cisco SFP modules. Each Cisco module has an internal serial EEPROM that is encoded with
security information. This encoding verifies that the module meets the requirements for the switch.
•
Inspect the SFP module. Exchange the suspect module with a known good module.
•
Verify that the module is supported on this platform. (The switch release notes on Cisco.com list the
SFP modules that the switch supports.)
•
Use the show interfaces privileged EXEC command to see if the port or module is error-disabled,
disabled, or shutdown. Re-enable the port if needed.
•
Make sure that all fiber-optic connections are clean and securely connected.
Interface Settings
Verify that the interface is not disabled or powered off. If an interface is manually shut down on either
side of the link, it does not come up until you re-enable the interface. Use the show interfaces privileged
EXEC command to see if the interface is error-disabled, disabled, or shut down on either side of the
connection. If needed, re-enable the interface.
Ping End Device
Ping from the directly connected switch first, and then work your way back port by port, interface by
interface, trunk by trunk, until you find the source of the connectivity issue. Make sure that each switch
can identify the end device MAC address in its Content-Addressable Memory (CAM) table.

Troubleshooting
Diagnosing Problems
Spanning Tree Loops
STP loops can cause serious performance issues that look like port or interface problems.
A unidirectional link can cause loops. It occurs when the traffic sent by the switch is received by the
neighbor, but the traffic from the neighbor is not received by the switch. A broken cable, other cabling
problems, or a port issue could cause this one-way communication.
You can enable UniDirectional Link Detection (UDLD) on the switch to help identify unidirectional link
problems. For information about enabling UDLD on the switch, see the “Understanding UDLD” section
in the switch software configuration guide on Cisco.com.
Switch Performance
Speed, Duplex, and Autonegotiation
Port statistics that show a large amount of alignment errors, frame check sequence (FCS), or
late-collisions errors, might mean a speed or duplex mismatch.
A common issue occurs when duplex and speed settings are mismatched between two switches, between
a switch and a router, or between the switch and a workstation or server. Mismatches can happen when
manually setting the speed and duplex or from autonegotiation issues between the two devices.
To maximize switch performance and to ensure a link, follow one of these guidelines when changing the
duplex or the speed settings.
•
Let both ports autonegotiate both speed and duplex.
•
Manually set the speed and duplex parameters for the interfaces on both ends of the connection.
•
If a remote device does not autonegotiate, use the same duplex settings on the two ports. The speed
parameter adjusts itself even if the connected port does not autonegotiate.
Autonegotiation and Network Interface Cards
Problems sometimes occur between the switch and third-party network interface cards (NICs). By
default, the switch ports and interfaces autonegotiate. Laptops or other devices are commonly set to
autonegotiate, yet sometimes issues occur.
To troubleshoot autonegotiation problems, try manually setting both sides of the connection. If this does
not solve the problem, there could be a problem with the firmware or software on the NIC. You can
resolve this by upgrading the NIC driver to the latest version.
Cabling Distance
If the port statistics show excessive FCS, late-collision, or alignment errors, verify that the cable distance
from the switch to the connected device meets the recommended guidelines. See the “Cables and
Adapters” section on page B-3.

SFP Module Cables
Each port must match the wave-length specifications on each end of the cable, and for reliable
communications, the cable must not exceed the allowable length. Copper 1000BASE-T SFP transceivers
use standard four twisted-pair, Category 5 (or greater) cable at lengths up to 328 feet (100 meters).

1. Modal bandwidth applies only to multimode fiber.
2. A mode-conditioning patch cord is required. Using an ordinary patch cord with MMF, 1000BASE-LX/LH SFP modules, and a short link distance can
cause transceiver saturation, resulting in an elevated bit error rate (BER). When using the LX/LH SFP module with 62.5-micron diameter MMF, you must
also install a mode-conditioning patch cord between the SFP module and the MMF cable on both the sending and receiving ends of the link. The
mode-conditioning patch cord is required for link distances greater than 984 feet (300 m).

3. 1000BASE-ZX SFP modules can send data up to 62 miles (100 km) by using dispersion-shifted SMF or low-attenuation SMF; the distance depends on
the fiber quality, the number of splices, and the connectors.
4. A mode-field diameter/cladding diameter = 9 micrometers/125 micrometers.
Note
When the fiber-optic cable span is less than 15.43 miles (25 km), insert a 5-decibel (dB) or 10-dB inline
optical attenuator between the fiber-optic cable plant and the receiving port on the 1000BASE-ZX SFP
module.

Console Port Adapter Pinouts
The console port uses an 8-pin RJ-45 connector, which is described in Table B-2 and Table B-3. If you
did not order a console cable, you need to provide an RJ-45-to-DB-9 adapter cable to connect the switch
console port to a PC console port. You need to provide an RJ-45-to-DB-25 female DTE adapter if you
want to connect the switch console port to a terminal. You can order an adapter (part number
ACS-DSBUASYN=). For console port and adapter pinout information, see Table B-2 and Table B-3.
Table B-2 lists the pinouts for the console port, the RJ-45-to-DB-9 adapter cable, and the console device.

Entering the Initial Configuration Information
To set up the switch, you need to complete the setup program, which runs automatically after the switch
powers on. You must assign an IP address and other configuration information necessary for the switch
to communicate with the local routers and the Internet.
IP Settings
You need this information:
•
Switch IP address
•
Subnet mask (IP netmask)
•
Default gateway (router)
•
Enable secret password
•
Enable password
•
Telnet password
Completing the Setup Program
Follow these steps to complete the setup program and to create an initial configuration for the switch:
Step 1
Enter Yes at these two prompts.
Would you like to enter the initial configuration dialog? [yes/no]: yes
At any point you may enter a question mark '?' for help.
Use ctrl-c to abort configuration dialog at any prompt.
Default settings are in square brackets '[]'.
Basic management setup configures only enough connectivity
for management of the system, extended setup will ask you
to configure each interface on the system.
Would you like to enter basic management setup? [yes/no]: yes
Step 2
Enter a host name for the switch, and press Return.
On a command switch, the host name is limited to 28 characters and on a member switch to 31
characters. Do not use -n, where n is a number, as the last character in a host name for any switch.
Enter host name [Switch]: host_name

Step 3
Enter an enable secret password, and press Return.
The password can be from 1 to 25 alphanumeric characters, can start with a number, is case sensitive,
allows spaces, but ignores leading spaces. The secret password is encrypted, and the enable password is
in plain text.
Enter enable secret: secret_password
Step 4
Enter an enable password, and press Return.
Enter enable password: enable_password
Step 5
Enter a virtual terminal (Telnet) password, and press Return.
The password can be from 1 to 25 alphanumeric characters, is case sensitive, allows spaces, but ignores
leading spaces.
Enter virtual terminal password: terminal-password
Step 6
(Optional) Configure Simple Network Management Protocol (SNMP) by responding to the prompts.
You can also configure SNMP later through the CLI. To configure SNMP later, enter no.
Configure SNMP Network Management? [no]: no
Step 7
Enter the interface name (physical interface or VLAN name) of the interface that connects to the
management network, and press Return. For this release, always use vlan1 as that interface.
Enter interface name used to connect to the
management network from the above interface summary: vlan1
Step 8
Configure the interface by entering the switch IP address and subnet mask and pressing Return. The IP
address and subnet masks shown below are examples.
Configuring interface vlan1:
Configure IP on this interface? [yes]: yes
IP address for this interface: 10.4.120.106
Subnet mask for this interface [255.0.0.0]: 255.0.0.0
Step 9
Enter Y to configure the switch as the cluster command switch. Enter N to configure it as a member
switch or as a standalone switch.
If you enter N, you can configure the switch as a command switch later through the CLI. To configure
it later, enter no.
Would you like to enable as a cluster command switch? [yes/no]: no
You have completed the initial configuration of the switch, and the switch displays its configuration.
This is an example of the configuration output:
The following configuration command script was created:
hostname switch1
enable secret 5 $1$Ulq8$DlA/OiaEbl90WcBPd9cOn1
enable password enable_password

Step 10
These choices appear:
[0] Go to the IOS command prompt without saving this config.
[1] Return back to the setup without saving this config.
[2] Save this configuration to nvram and exit.
If you want to save the configuration and use it the next time the switch reboots, select option 2 to
save it in NVRAM.
Enter your selection [2]:2
Make your selection, and press Return.
After you complete the setup program, the switch can run the default configuration that you created. To
change this configuration or to perform other management tasks, enter commands at the Switch> prompt.
