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 cor rect t he interference at their own expense.

The following information is for FCC complia nce of Class B devices: The equi pment des cribed in this manual generates and may rad iate 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 wit hou t Cisco’s written autho riz atio n may resul t in the equi pme nt no longe r comply ing with FCC re quir ements for Class A or Class B digital devices. In that event, your right to use the equipm ent may be lim ited by FCC regulations, and you may be required to correct any interference to radio or television communicati ons at your own expense.

You can determine whether your equipment is causing int erferen ce by turning it off. If the inter ference 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 interferenc e 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 circ uit from the tel evision or radio. (That is, make certain the equip ment and the television or radio are on circuits controlled by different circui t breakers or fuses.)

Chapter 1 Product Overview

The Catalyst 2948G switch has 48 autosensi ng and auto configuring 10/100BASE-T Fast Ethernet fixed ports. The Catalyst 2948G-GE-TX switch has 48 autosensing and autoconfiguring 10/ 100/100 0BASE-T ports. The Catalyst 2980G switch has 80 autosensing a nd autoco nfiguring 10/10 0BASE-T Fast Ethernet fixed ports.

GBIC Module Suppor t

The Catalyst 2948G and 2980G switche s each have two Gigabit Ethernet uplink ports with modular Gigabit Interface Converters (GBICs).

A GBIC is a hot-swappable input/output device that plugs into a Gigabit Ethernet port module and links the port module with a fiber-optic network. For a detailed description of Gigabit Et hernet ports, s ee the “GBIC Features” section on

page 4-2.

For a complete list of supported GBIC modules, see Table 4-1 on pag e 4-3.

Note The Catalyst 2948G-GE- TX switc h does not suppo rt GBIC modul es.

Switch Description

The Gigabit Ethernet port s can be con figured with a ny combinati on of GBIC types.

The Gigabit Ethernet ports on these modules are used primarily for backbone interconnection of ot her high- pe rform an ce s witc hes a nd rout er s.

SFP Module Support

The Catalyst 2948G-GE-TX switch has four small form-factor pluggable (SFP) module slots. The switch uses SFP modules to establish Gigabit connections. The SFP module slots are located on the front of the switch.

An SFP module is a hot-swappable input/output device that plugs into an SFP module slot, linking the port mo dule with a fiber-optic net work.

For a list of SFP modules supported by the Catalyst 2948G-GE-TX switch, see

Table 4-4 on page 4-12.

Switch Description

Note Catalyst 2948G-GE-TX sw itch only sup ports 1000 Mb ps and full-du plex modes

on SFP modules.

Except for the 1000BASE-T SFP module, all of the SFP modules are used to establish fiber-optic conne ct ions. You use fiber-optic cables with Lucent (L C) connectors to connect to an SFP module. The SFP modules support 850 to 1550 nanometer nom ina l wave lengths. T he se field- repl ace abl e mo dul es p rovid e the uplink optical interfaces, laser send (TX) and laser receive (RX).

Switch Components

Chapter 1 Product Overview

• The Catalyst 2948G switch uses the Cisco RPS 600 AC power supply

(PWR600-AC-RPS-CAB). The Cisco RPS 60 0 s uppo rts fou r exte rnal devices t hat us e up t o 150 W DC

each. Use a one-to-one cable (one connector at each cable end) to connect four external devices to t he f our DC out pu t power mo dul es.

The power source is part ia lly redu nda nt. The re are two AC input power modules for the Cisco RPS and one DC ou tput power module fo r each external dev ice. The A C input to the Cisco RPS is fully redundant, b ut the DC output to the external devices is not.

Warning

Attach only the Cisco RPS (model PWR600-AC-RPS) to the RPS receptacle.

Statement 112

• The Catalyst 2948G-GE- TX switch use s the Cisco RPS 675 (model

PWR675-AC-RPS-N1). The RPS 675 supports six external network devices an d provides DC power

to one failed device at a time. It automatically senses when the internal p ower supply of a connected device fails and provide s power to that device, which prevents loss of network traffic.

Attach only the Cisco RPS (model PWR675-AC-RPS-N1=) to the RPS receptacle.

Statement 100C

• The Catalyst 2980G-A swit ch uses the Cisco RPS 300

(PWR300-AC-RPS-N1). The RPS 300 supports six external network devices and provid es power to

one failed de vi ce at a tim e. I t a utom atic ally senses when the po we r sup ply of a connected device fails and provides the necessary power to the failed device to prevent loss of network traffic. When the internal power supply of the device has been brought up or replaced, the RPS auto matica lly stops powering the device.

1-12

Warning

Catalyst 2984G, 2948G-GE-TX, and 2980G Switch Hardware Installation Guide

Attach only the Cisco RPS (model PWR300-AC-RPS-N1) to the RPS receptacle.

Statement 100B

78-6286-05

Chapter 1 Product Overview

A Cisco RPS can only power one switch at a time. If more than one switch fails at the same time, any subsequ ent switch is not supported b y the RPS until th e first switch failure is resolved. For more information, refer to the documentation that was included with your RPS.

On the Catalyst 2948G switch , you must use a Y cable to connect the switch to two RPS 600 power supplies. Each RPS 600 has status LEDs (PSI and RPS).

On the Catalyst 2980G-A switch , each RPS 300 power supply has an individua l power cord and has status LEDs (PSI, PWR, and RPS).

The RPS uses redundant power supplies. If one of the power supplies in the RPS fails, the RPS will automatically switch over to the other power supply without forcing the switch to reb oot.

Note On the Catalyst 2948G-GE- TX and 2948 G switche s, only one power source can

supply power to the switch at a ny one time . W hen you ar e u sin g an RPS, unp lug the local power cord for the switch. If you are using the local power supply, the RPS can be connected but must not be powered on. The switches can be powered by both the internal power supply and the RPS at the same time .

network topology and searche s for loops. Th is process t akes about 30 seconds.

• The LED turns green when the switch and the target device have an

established link.

The LED does not light when the target device is not turned on, a cable problem exists, or a problem exists with the adapter installed in the target device.

If the STATUS LED do es not turn green or does not l ight at all , see

“Troubleshooting the Installat ion” sect ion on page 5-1 for solutions to cabling

problems.

Step 4 Reconfigure and res tart the target device if nec essar y. Step 5 Repeat Steps 1 through 4 to conne ct each port.

Connecting a Terminal to the Console Seri al and Ethernet Management Ports

The console serial and Ethernet management ports are locat ed on the front panel of the Catalyst 2948G, 29 48G- GE-T X, an d 2980G swi tche s. T he se por ts u se an RJ-45 media-depe ndent i nter face cr osse d-over (MDI X) conn ec tor, as shown in

Figure 3-16. For information a bout po rt p inout s, se e Appendix A, “Specifications.”

The Catalyst 2948G switches have a 10BASE-T management port. The Catalyst 2948G-GE-TX an d 2 980 G-A swi tch es have a 10/100BASE-T management port.

Note The MDIX Ethernet ports are cr ossed over internal ly. For an MDI-to-MDI or

MDIX-to-MDIX connection, use a crossover cable. For an MDI-to-MDIX connection, use a straight-through cable, which allows the Tx pins to connect with the Rx pins.

Verifying Switch Operation

After you have connected all the interfaces, check all connections, and then perform the following steps to po wer on the system to ve rify that it is oper ational :

Step 1 Before powering on the system, make sure t he connector i s installed se curely in a

grounded outlet at th e power-source end of th e power cord and that the sourc e power is within the range labeled on the back of the switch. When two power supplies are pr esent, m ake sur e that the second cord is conne cted to a s eparate l ine from the first, if possible.

Step 2 Check the co nsol e t erm in al an d ma ke su re i t i s powered o n.

engine is amber until the boot is complete.

Note Many of the interfa ce L E Ds do no t i llu mina te un til you configur e t he

interfaces.

When the system boot is complete (it takes a few seconds), the supervisor engine begins to initialize the interfaces. During this initialization, the interface LEDs flash on and off. When initialization is complete, the console screen displays a script and system bann er.

Chapter5 Troubleshooting the Installation

Getting Started

When the initial system boot is complete, verify the following:

• Power supplies are supplying power to the system.

• On Catalyst 2948G an d 2980G swi tch es, the s ystem fa n asse mbly is

operating.

• On Catalyst 2948G- GE-T X sw it ches, t h e bl ower is opera ting.

If all of these conditions are met and the hardware installation is complete, refer to the software configuration guide and the command reference for your switch to troubleshoot the software. However, if any of these conditions is not met, use t h e procedures in this chapter to isolate and, if possible, resolve the problem.

Problem Solving to the System Component Le vel

The key to success when troubleshooting the syste m is to isolate the problem to a specific system component. The first step is to compare what the system is doi n g to what it should be doing. Because a startup problem can usually be attributed to a single component, it is more efficient to isolate the problem to a subsystem rather than troubleshoot each component in the system separately.

The switch consists of the following subsystems:

• Power supply—Includes the power supplie s and power sup ply fans (se e

“Troubleshooting the Power Supply” section on page 5-4)

• Fans—The fan assembly sh oul d op er ate whe never system p ower is on. T he

fan assembly continues to operate even when the environmental monitor shuts the system down bec aus e of a n overtempera ture o r overvoltage condition (although i t will shut down in the event of a power supply shutdown).

The following are simple checks you can make to determine if there is a fan problem:

• Determine if the software is reporting a temperature problem.

• Listen to the fan assembly to determine if it is operating.

• Check for any obstructions that might be re strict ing the air flow through the

switch.

If you encounter a probl em in perf orming any of th e above checks, you should contact a custo mer ser vice re prese nta tive.

Identifying Startup Problems

LEDs indicate all system states in the startup sequence. By checking the LEDs, you can determine when and where the system failed in the startup sequence. If you have problems after the switch is powered on and the startup sequence is complete, refer to the software configuration guide for your switch.

After you connec t t he p ower cord to t he Ca taly st 2948G , 2948G -GE -T X, or 2980G switches, follow these steps:

Step 1 You should immediately hear the system fans begin to operate. If you do not, see

the “Troubleshooting the Power Supply” section on page 5-4. If you dete rmine that the power supplies are functioning normally and that the fans are faulty, contact a custo mer ser vice re prese nta tive.

Step 2 Check the power supply LEDs as follows:

• The power supply LED should turn green immediately when power is applied

to the switch. The L ED shou ld r em ain on du ri ng norm al s ystem o pe ratio n.

78-6286-05

• If the LED turns amber, see the section, “Troubleshooting the Power Supply”

section on page 5-4.

Step 3 Check that the LEDs on the front panel light as follows:

• The STATUS LED flash es amber onc e and stay s amber during diagnost ic

boot tests. It turns green when the switch is operational (on line). If the system software is unable to start up, this LED stays amber.

• The Link LED flashes amber once after diagnostic boot tests, and turns green

when the module is operational (on line). If no signal is detected, the Link LED turns off. The Link LED blinks ambe r conti nuously if the port is bad.

Note After the diagnostic boot tests, the single flash of amber on the Link LED

may occur too quickly to be de tected visua lly.

• If a STATUS LED is red or amber, contact a customer service representative

for instructions.

Step 4 If the boot informa tion an d system banner are not displaye d, verify that the

terminal is set correctly and that it is connected properly to the console port.

Troubleshooting the Power Supply

To help isolate a power subsystem problem, follow these steps:

Step 1 Check the power supply LED :

Note Power supply LEDs are labeled PSI , PWR, and RPS.

• If the LED i s ei ther o ff or a mber, unplug th e p ower cord , an d then pl u g the

power cord in again.

• If the LED remains off, there migh t be a probl em wi th t he AC source, or the

power cable. Conne ct th e power co rd t o ano t her power so urc e ( if on e i s available).

5-4

If the LED then lights, the problem is the first power source.

• If the LED fails to light after you connect the power supply to a new power

source, replace the power cord. If the LED still fails to light, the power supply is probably faulty.

Step 2 If a Redundant Power System (RPS) is installed, check the RPS LED:

If the LED is amb er o r off, rep eat the previous proc ed ure to tro ubl es hoot the second power supply.

Note If the power supply is a Cisco RPS 675 and the LED is amber, the RPS may be in

standby mode. Press the Standb y/Activ e button on the RPS to put it in activ e mode and the LED should then tu rn to green .

Chapter 5 Troubleshooting the Installa tion

Note If you are using an RPS, do not appl y power to the RPS an d the switch

simultaneously. Disconnect power from the internal power supply before turning the power on for th e RPS. Th e RPS contai ns mul tiple power supplies for redundant power protection. Refer to the RPS documentation for installation and configuration details.

Step 3 If you are unable to resolve the problem, contact a customer service representative

for instructions.
