Guidelines for Particulate Matter

Cisco Ethernet switches are equipped with cooling mechanisms, such as fans and blowers. However, these fans and blowers can draw dust and other particles, causing contaminant buildup inside the chassis, which can result in a system malfunction.

You must install this equipment in an environment as free as possible from dust and foreign conductive material (such as metal flakes from construction activities).

These standards provide guidelines for acceptable working environments and acceptable levels of suspended particulate matter:

Network Equipment Building Systems (NEBS) GR-63-CORE

National Electrical Manufacturers Association (NEMA) Type 1

International Electrotechnical Commission (IEC) IP-20

This precaution applies to all Catalyst 2960 switches except for the Catalyst 2960-8TC-L, 2960-8TC-S, 2960G-8TC-L, and 2960PD-8TT-L switches.

Installation Guidelines

This section does not apply to the Catalyst 2960 8-port switches. For information applicable to those switches, see Chapter 3 "Switch Installation (8-Port Switches)."

When you determine where to place the switch, be sure to observe these requirements:

For 10/100/1000 ports, cable lengths from the switch to connected devices must be no longer than 328 feet (100 meters).

The cables meet the specifications in Table B-1, which lists the cable specifications for 1000BASE-X and 100BASE-X SFP modules for the Catalyst 2960 switch. Catalyst 2960 switch SFP ports can use both GLC-GE-100XX and GLC-FE-100XX SFP modules.

When you use shorter lengths of single-mode fiber cable, you might need to insert an inline optical attenuator in the link to avoid overloading the receiver.

When the fiber-optic cable span is less than 15.43 miles (25 km), you should 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 at each end of the link.

The operating environment must be within the ranges listed in "Technical Specifications."

Clearance to front and rear panels meets these conditions:

You can easily read the front-panel indicators.

Access to ports is sufficient for unrestricted cabling.

The rear-panel power connector is within reach of an AC power receptacle.

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

Box Contents

The switch getting started guide on Cisco.com describes the box contents. If any item is missing or damaged, contact your Cisco representative or reseller for support.

Tools and Equipment

You need to supply a number-2 Phillips screwdriver to rack-mount the switch.

Verifying Switch Operation

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

If your configuration has an RPS, connect the switch and the RPS to the same AC power source. See Chapter 3 "Switch Installation (8-Port Switches)," and see the Cisco RPS documentation for more information.


Note When you connect the RPS to the switch, put the RPS in standby mode. Set the RPS to active mode during normal operation.


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


Warning Attach only the following Cisco RPS model to the RPS receptacle:
PWR-RPS2300, PWR675-AC-RPS-N1=. Statement 370

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. POST lasts approximately 1 minute. When the switch begins POST, the System, RPS, Status, Duplex, and Speed LEDs turn green. The System LED blinks green, and the other LEDs remain solid green.

When the POST completes successfully, the System LED remains green. The RPS LED remains green for some time and then reflects the switch operating status. The other LEDs turn off and then reflect the switch operating status. If a switch fails POST, the System LED turns amber.

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

After a successful POST, disconnect the power cord from the switch. Install the switch in a rack, on a wall, on a table, or on a shelf as described in the "Installing the Switch" section.

Note When the connectors are not being used, replace the dust covers on them for protection.



Connecting to the 10/100 and 10/100/1000 Ports

The switch 10/100/1000 ports configure themselves to operate at the speed of attached devices. If the attached ports do not support autonegotiation, you can explicitly set the speed and duplex parameters. Connecting devices that do not autonegotiate or that have their 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 port speed and duplex parameters on both ends of the connection.


Caution To prevent electrostatic-discharge (ESD) damage, follow your normal board and component handling procedures.


Step 1 When connecting to workstations, servers, routers, and Cisco IP Phones, connect a straight-through cable to an RJ-45 connector on the front panel. (See Figure 2-13.) When connecting to switches or repeaters, use a crossover cable. (See the "Cable and Adapter Specifications" section for cable-pinout descriptions.)

When you connect to 1000BASE-T-compatible devices, be sure to use a twisted four-pair, Category 5 or higher cable.

The auto-MDIX feature is enabled by default. For configuration information for this feature, see the switch software configuration guide or the switch command reference.

Figure 2-13 Connecting to an Ethernet Port

Step 2 Connect the other end of the cable to an RJ-45 connector on the other device. The port LED turns on when both the switch and the connected device have established link.

The port LED is amber while Spanning Tree Protocol (STP) discovers the topology and searches for loops. This can take up to 30 seconds, and then the port LED turns green. If the port LED does not turn on, the device at the other end might not be turned on, or there might be a cable problem or a problem with the adapter installed in the attached device. See Chapter 4 "Troubleshooting," for solutions to cabling problems.

Step 3 Reconfigure and reboot the connected device if necessary.

Step 4 Repeat Steps 1 through 3 to connect each device.


Installing and Removing SFP Modules

SFP modules are installed in SFP module slots on the front of the Catalyst 2960 switches. These field-replaceable modules provide the uplink optical interfaces, laser send (TX) and laser receive (RX).

You can use any combination of SFP modules. Refer to the Catalyst 2960 switch release notes for the list of SFP modules that the Catalyst 2960 switch supports. Each SFP module must be of the same type as the SFP module on the other end of the cable, and the cable must not exceed the stipulated cable length for reliable communications. See the "SFP Module Cable Specifications" section for cable stipulations for SFP module connections. Use only Cisco SFP modules on the Catalyst 2960 switch. Cisco SFP modules and the Catalyst 2960 switch support the Quality ID feature. Only SFP modules with the Quality ID feature are supported.

For detailed instructions on installing, removing, and cabling the SFP module, refer to your SFP module documentation.

Installing SFP Modules

Figure 2-14 shows an SFP module that has a bale-clasp latch.


Caution We strongly recommend that you do not install or remove the SFP module with fiber-optic cables attached to it because of the potential damage to the cables, the cable connector, or the optical interfaces in the SFP module. Disconnect all cables before removing or installing an SFP module.

Removing and installing an SFP module can shorten its useful life. Do not remove and insert SFP modules more often than is absolutely necessary.

Figure 2-14 SFP Module with a Bale-Clasp Latch


Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface on the chassis.

Step 2 Find the send (TX) and receive (RX) markings that identify the top side of the SFP module.


Note On some SFP modules, the send and receive (TX and RX) markings might be replaced by arrows that show the direction of the connection, either send or receive (TX or RX).


Step 3 Align the SFP module in front of the slot opening.

Step 4 Insert the SFP module into the slot until you feel the connector on the module snap into place in the rear of the slot. See Figure 2-15.

Step 5 Remove the dust plugs from the SFP module optical ports and store them for later use.


Caution Do not remove the dust plugs from the SFP module port or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the SFP module ports and cables from contamination and ambient light.

Step 6 Insert the LC cable connector into the SFP module.


Removing SFP Modules


Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface on the chassis.

Step 2 Disconnect the LC connector from the SFP module.


Tip 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 to keep the optical interfaces clean.

Step 4 Unlock and remove the SFP module, as shown in Figure 2-16.

If the module has a bale-clasp latch, pull the bale out and down to eject the module. If the bale-clasp latch is obstructed and you cannot use your index finger to open it, use a small, flat-blade screwdriver or other long, narrow instrument to open the bale-clasp latch.

Step 3 Insert the other cable end into a fiber-optic receptacle on a target device.

Step 4 Observe the port status LED.

The LED turns green when the switch and the target device have an established link.

The LED turns amber while the STP discovers the network topology and searches for loops. This process takes about 30 seconds, and then the port LED turns green.

If the LED is off, the target device might not be turned on, there might be a cable problem, or there might be problem with the adapter installed in the target device. See Chapter 4 "Troubleshooting," for solutions to cabling problems.

Step 5 If necessary, reconfigure and restart the switch or target device.


Connecting to 1000BASE-T SFP Modules


Caution To prevent ESD damage, follow your normal board and component handling procedures.


Step 1 Insert one end of the cable into the SFP module port (see Figure 2-18). When connecting to servers, workstations, and routers, insert a four twisted-pair, straight-through cable in the RJ-45 connector. When connecting to switches or repeaters, insert a four twisted-pair, crossover cable.


Note When connecting to a 1000BASE-T device, be sure to use a four twisted-pair, Category 5 or higher cable.



Note The auto-MDIX feature is enabled by default. For configuration information for this feature, see the switch software configuration guide or the switch command reference.

Step 2 Insert the other cable end in an RJ-45 connector on a target device.

Step 3 Observe the port status LED.

The LED turns green when the switch and the target device have an established link.

The LED turns amber while the STP discovers the network topology and searches for loops. This process takes about 30 seconds, and then the port LED turns green.

If the LED is off, the target device might not be turned on, there might be a cable problem, or there might be problem with the adapter installed in the target device. See Chapter 4 "Troubleshooting," for solutions to cabling problems.

Step 4 If necessary, reconfigure and restart the switch or target device.


Connecting to a Dual-Purpose Port

You can configure the dual-purpose port as either a 10/100/1000 port or as an SFP module port. For a detailed description of this port, see the "Dual-Purpose Port" section.


Step 1 Connect an RJ-45 connector to the 10/100/1000 port, or install an SFP module into the SFP module slot, and connect a cable to the SFP module port, as shown in Figure 2-19.

Only one port can be active at a time. If both ports are connected, the SFP module port has priority. You cannot configure the priority setting.

For more information about RJ-45 connectors and SFP modules, see the "Connecting to the 10/100 and 10/100/1000 Ports" section, "Installing and Removing SFP Modules" section, and the "Connecting to SFP Modules" section.

Step 2 Connect the other end of the cable to the other device. The switch automatically detects the connection and configures the port.

By default, the switch automatically selects the interface type the first time a port links up. For subsequent links, you must use the media-type interface configuration command to manually configure either the RJ-45 connector or the SFP module connector. For more information, see the command reference.


Where to Go Next

If the default configuration is satisfactory, the switch does not need further configuration. You can use any of these management options to change the default configuration:

Start the device manager, which is in the switch memory, to manage individual switches. The device manager is an easy-to-use web interface that offers quick configuration and monitoring. You can access the device manager from anywhere in your network through a web browser. For more information, see the device manager online help.

Start the Network Assistant application, which is described in the Getting Started with Cisco Network Assistant guide. Through this GUI, you can configure and monitor a switch cluster or an individual switch.

Use the CLI from the console to configure the switch as a member of a cluster or as an individual switch. See the Catalyst 2960 Switch Software Configuration Guide and the Catalyst 2960 Switch Command Reference on Cisco.com for information on using the CLI with a Catalyst 2960 switch.

Start an SNMP application such as the CiscoView application.
