PoE Ports

The ports provide PoE support for devices compliant with IEEE 802.3af and IEEE 802.3at and also provide PoE support for Cisco IP Phones and Cisco Aironet Access Points. The PoE switch ports are Power Source equipment (PSE) and Power Device (PD) capable and source power to PD devices connected to the downlink ports. A switch can source POE power of up to 30.8W per port.

Depending on the switch model and the number of PoE ports, the maximum switch power output varies between 236.89 W to 440.66 W. On a per-port basis, you can 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 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.

Console Ports

The 10/100/1000 ports use RJ-45 connectors with Ethernet pinouts. 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.

The console ports connect the switch to a PC running Microsoft Windows or to a terminal server.

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.

Cisco Catalyst 2960-L Series 24-Port and 48-Port Switch Hardware Installation Guide

Product Overview

USB Type A Port

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.

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.

USB Type A Port

The USB Type A port provides access to external USB flash devices (also known as thumb drives or USB keys).

The port supports Cisco USB flash drives with capacities from 128 MB to 8 GB (USB devices with port densities of 128 MB, 256 MB, 1 GB, 4 GB, and 8 GB are supported). 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.

It provides you with the ability to automatically upgrade the internal flash with the USB drive's configuration and image for emergency switch recovery using USB auto-upgrade. This feature checks the internal flash for a bootable image and configuration and if either image or the configuration is not available, then the USB drive is checked for boot images and configuration. If the boot image and configuration are available, these are copied to flash for the reboot.

SFP Module Slots

The switch has four 1G SFP or 10G SFP+ module slots. The SFP and SFP+ modules provide copper or fiber-optic connections to other devices. These transceiver modules are field replaceable, and provide the uplink interfaces when installed in an SFP module slot. The SFP modules have LC connectors for fiber-optic connections or RJ-45 connectors for copper connections. The SFP slots support only SFP modules.

When determining where to install the switch, verify that these guidelines are met:

Clearance to the switch front and rear panel meets these conditions:

•

Front-panel LEDs can be easily read.

◦

Access to ports is sufficient for unrestricted cabling.

◦

AC power cord can reach from the AC power outlet to the connector on the switch rear panel.

◦

Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting

•

fixtures. Make sure that the cabling is safely away from other devices that might damage the cables.

Airflow around the switch and through the vents is unrestricted.

•

Temperature around the unit does not exceed 113°F (45°C). If the switch is installed in a closed or

•

multirack assembly, the temperature around it might be greater than normal room temperature.

Humidity around the switch does not exceed 90 percent.

•

For 10/100/1000 fixed ports, the cable length from a switch to a connected device cannot exceed 328

•

feet (100 meters).

Cooling mechanisms, such as fans and blowers in the switch, can draw dust and other particles causing

•

contaminant buildup inside the chassis, which can result in system malfunction. You must install this equipment in an environment as free from dust and foreign conductive material (such as metal flakes from construction activities) as is possible.

Cisco Catalyst 2960-L Series 24-Port and 48-Port Switch Hardware Installation Guide

Verifying Switch Operation

Before you install the switch in a rack, on a wall, or on a table or shelf, power on the switch and verify that it passes POST.

To power on the switch, plug one end of the AC power cord into the switch AC power connector, and plug the other end into an AC power outlet.

As the switch powers on, it begins the POST, a series of tests that runs automatically to ensure that the switch functions properly. LEDs can blink during the test. The SYST LED blinks green, and the other LEDs remain solid green.

When the switch completes POST successfully, the SYST LED remains green. The other LEDs turn off and then reflect the switch operating status. If a switch fails POST, the SYST LED turns amber.

POST failures are usually fatal. Call Cisco technical support representative if your switch fails POST.

After a successful POST, unplug the power cord from the switch and install the switch in a rack, on a wall, on a table, or on a shelf.

10/100/1000 PoE and PoE+Port Connections

The ports provide PoE support for devices compliant with IEEE 802.3af and 802.3at (PoE+), 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 when an IP phone or an access point is connected.

To access an advanced PoE planning tool, use the Cisco Power Calculator available on Cisco.com at this URL: http://tools.cisco.com/cpc/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 system heat dissipation.

10/100/1000 PoE and PoE+Port Connections

Warning

Caution

Step 1 Step 2

Category 5e and Category 6 cables can store high levels of static electricity. Always ground the cables to a suitable and safe earth ground before connecting them to the switch or other devices.

Noncompliant cabling or powered devices can cause a PoE port fault. Use only standard-compliant cabling to connect Cisco prestandard IP Phones and wireless access points, IEEE 802.3af, or 802.3at (PoE+) compliant devices. You must remove any cable or device that causes a PoE fault.

Procedure

Connect one end of the cable to the switch PoE port.

Connect the other end of the cable to an RJ-45 connector on the other device. The port LED turns on when both devices have established link. The port LED is amber while STP discovers the topology and searches for loops. This process takes about 30 seconds, and then the port LED turns green. If the LED is off, the other device might not be turned on, there might be a cable problem, or there might be a problem with the adapter in the other device.

Step 3 Step 4

Reconfigure and reboot the connected device, if needed.

Repeat Steps 1 through 3 to connect each device.

Note

Many legacy powered devices, including older Cisco IP phones and access points that do not fully support IEEE 802.3af, might not support PoE when connected to the switches by a crossover cable.

Cisco Catalyst 2960-L Series 24-Port and 48-Port Switch Hardware Installation Guide

10/100/1000 Port Connections

The switch 10/100/1000 port configuration changes to operate at the speed of the attached device. If the attached ports do not support autonegotiation, you can manually set the speed and duplex parameters. Connecting devices that do not autonegotiate or that have the speed and duplex parameters manually set can reduce performance or result in no linkage.

To maximize performance, choose one of these methods for configuring the Ethernet ports:

Let the ports autonegotiate both speed and duplex.

•

Set the interface speed and duplex parameters on both ends of the connection.

•

Auto-MDIX Connections

The autonegotiation and the auto-MDIX features are enabled by default on the switch.

With autonegotiation, the switch port configurations change to operate at the speed of the attached device. If the attached device does not support autonegotiation, you can manually set the switch interface speed and duplex parameters.

With auto-MDIX, the switch detects the required cable type for copper Ethernet connections and configures the interface accordingly.

If auto-MDIX is disabled, use the guidelines in this table to select the correct cable.

•

Diagnosing Problems

The LEDs on the front panel provide troubleshooting information about the switch. They show POST failures, port-connectivity problems, and overall switch performance. You can also get statistics from Device Manager, from the CLI, or from an SNMP workstation.

Switch POST Results

CHAPTER 3

POST failures are usually fatal. Contact your Cisco technical support representative if your switch does not pass POST.

Switch LEDs

If you have physical access to the switch, look at the port LEDs for troubleshooting information about the switch. See the LED section 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 situation because the port has many packet errors or the port constantly flaps (loses and regains link).

Cisco Catalyst 2960-L Series 24-Port and 48-Port Switch Hardware Installation Guide

Switch Connections

Examine or 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 faulty media convertors (fiber-optic-to-copper).

Try the cable in another port or interface, if possible, to see if the problem follows the cable.

•

Ethernet and Fiber-Optic Cables

Make sure that you have the correct cable for the connection.

For Ethernet, use Category 3 copper cable for 10 Mb/s UTP connections. Use either Category 5, Category

•

5e, or Category 6 UTP for 10/100/1000 Mb/s connections.

For fiber-optic cables, verify that you have the correct cable for distance and port type. Ensure that the

•

connected device ports match and use the same type of encoding, optical frequency, and fiber type.

For copper connections, determine if a crossover cable was used when a straight-through was required

•

or the reverse. Enable auto-MDIX on the switch, or replace the cable.

Troubleshooting

Link Status

Verify that both sides have link. A single 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 fully functional. The cable might have encountered physical stress that causes 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.

•

Ensure 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.

•

Check for loose connections. Sometimes a cable appears to be seated, but is not. Disconnect the cable

•

and then reconnect it.

10/100/1000 Port Connections

A port appears to malfunction:

Use the Mode button to show the status for all ports.

•

Use the show interfaces privileged EXEC command to see if the port is error-disabled, disabled, or

•

shutdown. Reenable the port if necessary.

10/100/1000 PoE+ Port Connections

A powered device connected to a PoE port does not receive power:

Cisco Catalyst 2960-L Series 24-Port and 48-Port Switch Hardware Installation Guide

Troubleshooting

Switch Connections

Use the Mode button to show the PoE status for all ports.

•

Use the show interfaces privileged EXEC command to see if the port is in error-disabled, disabled, or

•

shutdown. Reenable the port if necessary.

Verify that the power supply installed in the switch meets the power requirements of your connected

•

devices.

Verify that there is sufficient PoE power budget to provide power to the attached device. Use the show

•

power inline global configuration command to check on the available PoE power budget.

Verify the cable type. Many legacy powered devices, including older Cisco IP phones and access points

•

that do not fully support IEEE 802.3af, might not support PoE when connected to the switch by a crossover cable. Replace the crossover cable with a straight-through cable.

Caution

SFP and SFP+ Module

Use only Cisco SFP or SFP+ modules in the switch. Each Cisco module has an internal serial EEPROM that is encoded with security information. This encoding provides a way for Cisco to identify and validate 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. Reenable the port if needed.

Make sure that all fiber-optic connections are properly cleaned 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 reenable the interface. Use the show interfaces privileged EXEC command to see if the interface is error-disabled, disabled, or shutdown on either side of the connection. If needed, reenable the interface.

Noncompliant cabling or powered devices can cause a PoE port fault. Use only standard-compliant cabling to connect Cisco prestandard IP Phones and wireless access points or IEEE 802.3af-compliant devices. You must remove any cable or device that causes a PoE fault.

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.

Cisco Catalyst 2960-L Series 24-Port and 48-Port Switch Hardware Installation Guide

Switch Performance

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 its neighbor, but the traffic from the neighbor is not received by the switch. A broken fiber-optic 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.

Switch Performance

Speed, Duplex, and Autonegotiation

If the port statistics show a large amount of alignment errors, frame check sequence (FCS), or late-collisions errors, this might mean a speed or duplex mismatch.

A common issue with speed and duplex 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.

Troubleshooting

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 autonegotiation 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 your 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.

Identifying a Crossover Cable

To identify a crossover cable, compare the two modular ends of the cable. Hold the cable ends side-by-side, with the tab at the back. The wire connected to the pin on the outside of the left plug should be a different color from the wire connected to the pin on the inside of the right plug.

Figure 31: Identifying a Crossover Cable

Console Port Adapter Pinouts

The RS-232 console port uses an 8-pin RJ-45 connector. Use an RJ-45-to-DB-9 adapter cable to connect the switch console port to a console PC. You need to provide a RJ-45-to-DB-25 female DTE adapter to connect the switch console port to a terminal.

Step 4

Step 5

Step 6 Step 7

Step 8

Verify that no devices are connected to the switch. Initially, the switch acts as a DHCP server.

Confirm that the STAT LED is solid green. This indicates that POST is complete. If the STAT LED turns amber, the device failed POST. Reconnect the AC power cord to the AC power connector of your device and to a grounded AC outlet. If the STAT LED still does not turn green, contact your Cisco representative or retailer.

Press and hold the Mode button for 3 seconds. When all of the LEDs above the Mode button turn green, release the Mode button immediately. Caution: If the LEDs next to the Mode button blink green, release the button. Blinking green LEDs indicate that the device is already in Setup mode. Continuing to hold the Mode button after the LEDs have turned green, exits the Setup mode.

Connect a straight-through Category 5 Ethernet cable to a 10/100/1000 Ethernet port on the switch front panel and to the Ethernet port on the PC.

Verify that the port LEDs on the PC and on your device are solid green or blinking green. This indicates a successful connection.

Wait 30 seconds.

To log on to the device using an Internet browser on your PC, type the IP address 10.0.0.1 or 10.0.0.3 in the address bar of your Internet browser and press Enter.

Type the following default credentials: username: cisco, password: cisco and press Enter. The Configuration Setup wizard is displayed. Click Go to Wizard.
