THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.
THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.
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 correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate 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 without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference 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 interference 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 circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

There are 28 1000BASE-X Ethernet ports using SFP interfaces.

Console Port

A console serial port (RJ-45) provides for switch management using standard console equipment. (See
Appendix A, “Specifications,” for the console and management ports.
The Management port on the front panel is only operational when the switch is in rommon mode. When in use, it offers the same TCP/IP based management services available using inband access (Telnet, SNMP, etc.). IP address configuration using BOOTP is supported on the Management port; it also supports image download to the switch.
Figure 1-4 and Figure 1-5 show the location of the management and console ports
on the switches.

The Catalyst 4900 series switches have two redundant internal 300 W AC or 300 W
DC power supplies.
The internal power supplies have individual power cords and status LEDs (PS1 and PS2 on the front panel). There are also LEDs on the power supplies that show status for the input (Input OK) and output (Output OK) currents. A power cord is used to connect the power supplies to the site power source. There is a power switch on the AC power supplies; AC power is present when a power cord is plugged into a power supply and the switch is set to the On position. DC power supplies do not have an on/off switch and do not provide a cable for connection to a DC power source.

Figure 1-9 On/Off Switch Locations
The switch will start with only one power supply plugged in, but redundant failover and load sharing will not be available in this configuration. We recommend that you always connect both power supplies to separate AC or DC circuits for optimal power reliability.
For safety reasons, the AC power supply needs to be switched off and unplugged before it is removed from a chassis or inserted into a chassis. DC supplies should have power shut off from the source before they are removed.
If only one power supply will be used, you must use the blank faceplate supplied to cover the empty power bay.

Power Management for the Switch

You can choose AC or DC power supplies for your switch. The Catalyst 4900 series switches support the following power supplies:
300 W AC
300 W DC
A redundant power supply can be identified and diagnosed by a running system regardless of its input status. AC and DC supplies are interchangeable.
Power Management Modes
Catalyst 4900 series switches support the redundant power management mode. In this mode, if both power supplies are operating normally, each provides from 20/80 to 45/55 percent of the total system power requirements at all times. If one power supply fails, the other unit increases power to 100 percent of the total power requirement.

Site Power Requirements, page 2-2
Grounding Requirements, page 2-6
Safety Overview, page 2-7
Site Planning Checklist, page 2-9
For detailed information about cabling requirements, see Chapter 4, “Transceiver
Modules.”
Note A site planning checklist is provided on page 3-5 to help ensure that you complete
all site planning activities before you install the switch.

Site Environmental Requirements

Planning a proper location for the switch and layout for your equipment rack or wiring closet is essential for successful system operation. You should install the switch in an enclosed, secure area, ensuring that only qualified personnel have access to the switch and control of the environment. Equipment that is placed too closely together or that is inadequately ventilated can cause system overtemperature conditions. In addition, poor equipment placement can make chassis panels inaccessible and difficult to maintain.
Catalyst 4900 Series Switch Installation Guide
78-18039-02
2-1

Site Power Requirements

The switch operates as a standalone system mounted in a rack in a secure wiring closet. It requires a dry, clean, well-ventilated, and air-conditioned environment. To ensure normal operation, maintain ambient airflow. If the airflow is blocked or restricted, or if the intake air is too warm, an overtemperature condition can occur. The switch environmental monitor can then shut down the system to protect the system components.
To ensure normal operation and avoid unnecessary maintenance, plan your site configuration and prepare your site before installation. After installation, make sure that the site maintains an ambient temperature of 0 to 40° C (32 to 104° F). It is essential to keep the area around the chassis as free from dust and foreign conductive material (such as metal flakes from nearby construction activity) as is possible.
Multiple switches can be rack-mounted with little or no clearance above and below the chassis. However, when mounting a switch in a rack with other equipment, or when placing it on the floor near other equipment, ensure that the exhaust from other equipment does not blow into the intake vents of the chassis.
Cooling air is drawn in through the sides and exhausted through the rear of the chassis. Keep the sides and rear clear of obstructions, including dust and foreign conductive material, and away from the exhaust ports of other equipment.
Appendix A, “Specifications,” lists the operating and nonoperating environmental
site requirements for the switches. To maintain normal operation and ensure high system availability, maintain an ambient temperature and EMI-free and continuous power at your site. The environmental ranges listed in those within which the switch will continue to operate; however, a measurement that approaches the minimum or maximum of a range indicates a potential problem. You can maintain normal operation by anticipating and correcting environmental anomalies before they exceed the maximum operating range.

EMI Recommendations

Follow these guidelines when setting up the site wiring. When planning the location of the new system, consider electromagnetic interface (EMI), the distance limitations for signaling, and connector compatibility.
When wires are run for any significant distance in an electromagnetic field, radio frequency interference (RFI) can occur between the field and the signals on the wires.
Bad plant wiring can result in radio frequency interference.
Strong EMI, especially when caused by lightning or radio transmitters, can
destroy the signal drivers and receivers in the switch and can create an electrical hazard by conducting power surges through lines and into equipment.
Note To predict and remedy strong EMI, you might need to consult RFI experts.

Rack-Mounting the Switch
Warning
To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:
• This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
• When mounting this unit in a partially filled rack, load the rack from the bottom to the
top with the heaviest component at the bottom of the rack.
• If the rack is provided with stabilizing devices, install the stabilizers before mounting
or servicing the unit in the rack.

Rack-Mounting Guidelines

Before rack-mounting the switch, ensure the following:
The equipment rack is the proper size.
The width of the rack, between the two front mounting strips or rails, must be 17.75
The depth of the rack, between the front and rear mounting strips, must be at least 19.25
The rack must have sufficient vertical clearance to insert the chassis. The chassis height is 1.75 inches (4.45 cm).
Statement 1006

inches (48.9 cm) but not more than 32 inches (81.3 cm).
78-18039-02
The equipment rack is stable and in no danger of falling over.
Ensure that the shelf is constructed to support the weight and dimensions of the chassis. For physical specifications, see
Appendix A,
“Specifications.”
We recommend that you bolt the rack to the floor.
Mount the unit at the bottom of the rack if it is the only unit in the rack.
Install heavier equipment in the lower half of the rack to maintain a low center of gravity and prevent the rack from becoming top-heavy and tipping over.
Catalyst 4900 Series Switch Installation Guide
3-3
Rack-Mounting the Switch
The equipment rack is properly ventilated.
Chapter 3 Installing the Switch
Install the stabilizers before mounting or servicing the switch in the rack (if the rack is provided with stabilizing devices).
Install the chassis in an enclosed rack only if it has adequate ventilation or an exhaust fan; use an open rack whenever possible.
Ensure that the ambient temperature of the rack environment does not exceed a maximum temperature of 104° F (40° C). Note that if the switch is installed in a closed or multiunit rack assembly, the ambient operating temperature of the rack environment might be higher than the ambient room temperature.
Note that a ventilation system in a closed rack that is too powerful might also prevent cooling by creating negative pressure around the chassis and redirecting the air away from the chassis intake vent. If necessary, operate the chassis with the rack open.
To prevent airflow restriction, allow at least 3 inches (7.6 cm) of clearance around the ventilation openings on the sides of the chassis.
Use baffles correctly to assist in cooling the chassis.
Note that equipment near the bottom of a rack may generate excessive heat that is drawn upward and into the intake ports of equipment above, leading to overtemperature conditions in the chassis at or near the top of the rack.
3-4
Consider the equipment and cabling that is already installed in the rack. Ensure that cables from other equipment will not obstruct the airflow through the chassis or impair access to the power supplies or switching modules. Route cables away from field-replaceable components to avoid disconnecting cables unnecessarily for equipment maintenance or upgrades.
Allow at least 3 to 4 feet (91.4 to 121.9 cm) of clearance behind the rack for maintenance and removal of switch assemblies. If the rack is mobile, you can push it back within 1 foot (30.45 cm) of a wall or cabinet for normal operation and pull it out when necessary for maintenance.

Chapter 3 Installing the Switch

Lifting the Chassis Safely

The chassis is not intended to be moved frequently. Before you install the switch, ensure that your site is properly prepared so that you can avoid moving the chassis later to accommodate power sources and network connections.
Whenever you lift a chassis or any heavy object, follow these guidelines:
Ensure that your footing is solid, and balance the weight of the chassis
between your feet.
Lift the chassis slowly; never move suddenly or twist your body as you lift.
Keep your back straight and lift with your legs, not your back. If you must
bend down to lift the chassis, bend at the knees, not at the waist, to reduce the strain on your lower back muscles. (See
Always disconnect all external cables before lifting or moving the chassis.

Tip For complete information on inspecting and cleaning fiber-optic connections,
refer to the white-paper document at this URL:
http://www.cisco.com/en/US/tech/tk482/tk876/technologies_white_paper09186a 0080254eba.shtml

Module Maintenance Guidelines

To properly maintain modules, follow these guidelines:
To prevent ESD damage, follow normal handling procedures.
When the module is stored or when a fiber-optic cable is not plugged in,
always keep plugs in the optical bores.
The most common source of contaminants in the optical bores is debris
picked up on the ferrules of the optical connectors. Use an alcohol swab or Kim-Wipe to clean the ferrules of the optical connector.

Cleaning the Fiber-Optic Connectors

Warning
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments.
Statement 1051
Cleaning the Fiber-Optic Connectors
In a fiber-optic system, light is transmitted through an extremely small fiber core, often 62.5 microns or less in diameter. Because dust particles range from a tenth of a micron to several microns in diameter, dust and any contamination at the end of the fiber core can degrade the performance of the connector interface where the two cores meet. Therefore, the connector must be precisely aligned, and the connector interface must be absolutely free of trapped foreign material.
Catalyst 4900 Series Switch Installation Guide
78-18039-02
4-5
Cleaning the Fiber-Optic Connectors
Connector loss, or insertion loss, is a critical performance characteristic of a fiber-optic connector. Return loss is also an important factor. Return loss specifies the amount of reflected light; the lower the reflection, the better the connection. The best physical contact connectors have return losses greater than –40 dB, although –20 to –30 dB is more common.
The connection quality depends on the type of connector and the proper cleaning and connection techniques. Dirty fiber connectors are a common source of light loss. Keep the connectors clean at all times, and keep the dust covers installed when the connectors are not in use.
Before installing any type of cable or connector, use a lint-free alcohol pad from a cleaning kit to clean the ferrule, the protective white tube around the fiber, and the end-face surface of the fiber.
As a general rule, whenever there is a significant, unexplained loss of light, clean the connectors.
Caution Use extreme care when removing or installing connectors so that you do not
damage the connector housing or scratch the end-face surface of the fiber. Always install protective covers on unused or disconnected components to prevent contamination. Always clean fiber connectors before installing them.
Chapter 4 Transceiver Modules
4-6
To clean the optical connectors, use a CLETOP cassette cleaner (type A for SC connectors or type B for MT-RJ connectors) and follow the product directions. If a CLETOP cassette cleaner is not available, follow these steps:
Step 1 Use a lint-free tissue soaked in 99 percent pure isopropyl alcohol to gently wipe
the faceplate. Wait five seconds for the surfaces to dry, and repeat.
Step 2 Remove any residual dust from the faceplate with clean, dry, oil-free compressed
air.
Warning

Chapter 4 Transceiver Modules
Step 3 Use a magnifying glass or inspection microscope to inspect the ferrule at an angle.
Do not look directly into the aperture. Repeat the process if any contamination is detected.

Additional Guidelines

The connectors used inside the system have been cleaned by the manufacturer and connected to the adapters in the proper manner. The operation of the system should be error free if the customer provides clean connectors on the application side, follows the previous directions, and follows these guidelines:
Clean the connectors using either a CLETOP cassette cleaner (Type A for SC
connectors and Type B for MT-RJ connectors) or lens tissues before connecting to the adapters. Use pure alcohol to remove contamination.
Do not clean the inside of the connector adapters.
Do not use force or quick movements when connecting the fiber-optic
connectors in the adapters.
Cleaning the Fiber-Optic Connectors
78-18039-02
Cover the connectors and adapters to keep the inside of the adapters or the
surface of the connectors from getting dirty when you are not using the connectors or while you are cleaning the chassis.

Problem Solving to the System Component Level, page 5-2
Identifying Startup Problems, page 5-3
Troubleshooting the Power Supply, page 5-5
Contacting Customer Service, page 5-6
If your system has problems starting up, use the information in this chapter to help isolate the cause. Problems with the initial startup are often caused by poor or improper connections. Although temperature conditions above the maximum acceptable level rarely occur at initial startup, environmental monitoring functions are included because they also monitor DC-line voltages.
78-18039-02
Note For configuration questions or problems, refer to the software configuration guide
or the command reference publication.
Catalyst 4900 Series Switch Installation Guide
5-1
Chapter 5 Troubleshooting the Installation

Getting Started

Getting Started
When the initial system boot is complete, verify the following:
Power supplies are supplying power to the system.
The system fan assembly is operating.
System software boots successfully.
If all of these conditions are met and the hardware installation is complete, refer to the Software Configuration Guide and the Command Reference publications to troubleshoot the software. However, if any of these conditions are not met, use the procedures in this chapter to isolate and, if possible, resolve the problem.

Problem Solving to the System Component Level

The key to success when troubleshooting the system is to isolate the problem to a specific system component. The first step is to compare what the system is doing 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 separate component in the system.
5-2
The switch consists of the following subsystems:
Power supply—Includes the power supply and power supply cooling. (See
the
“Troubleshooting the Power Supply” section on page 5-5.)
Fan assembly system—The chassis fan assembly should operate whenever
system power is on. Usually, it continues to operate even when the environmental monitor shuts down the system because of an overtemperature or overvoltage condition. (It will shut down for a power supply shutdown.) You should be able to hear the fan assembly to determine whether or not it is operating. If the FAN LED is orange and you determine that the fan assembly is not operating, you should immediately contact a customer service representative. There are no installation adjustments that you can make if the fan assembly does not function properly at the initial startup.
Catalyst 4900 Series Switch Installation Guide
78-18039-02
Chapter 5 Troubleshooting the Installation

Identifying Startup Problems

When you connect the power cords to the switch, follow these steps:
Step 1 Flip the power switches to the on position (AC powered systems only). Step 2 Verify that power is available to the power supplied from the site AC or DC
source. Flip breakers and fuses if necessary.
Step 3 Listen for the system fan assembly. If you do not immediately hear the system fan
assembly begin to operate, see
page 5-5.
Step 4 If you determine that the power supplies are functioning normally and that the fan
assembly is faulty, contact a customer service representative. If the system fan assembly does not function properly at initial startup, there are no installation adjustments that you can make.

LED Readings

Step 1 Compare the LED states to those in Table 5-1.
78-18039-02
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. To check the LEDs, follow these steps:

In a dual power supply configuration (alternate unit powered) the DC input is less than 33 +/-3V, or the power supply is turned off.
In a single supply configuration, the LED shall be off to signal that DC input is less than 33 +/-3V, or the power supply is turned off.
DC output voltages are within the normal operating range.
Output voltage between the minimum and maximum limits will not create an output fail alarm. Output voltages below the minimum or above the maximum will create an output fail alarm and cause the LED to illuminate red.
5-4
Step 2 Verify that the LEDs on the front panel are lit:
The STATUS LED flashes yellow during diagnostic boot tests. It is green
when the switch is operational (online). If the system software is unable to start up, this LED stays orange.
Catalyst 4900 Series Switch Installation Guide
78-18039-02
Chapter 5 Troubleshooting the Installation
The port LEDs (1-48) are green when the module is operational (online). If
no signal is detected, the LINK LED is off. The port LED remains yellow if the port is disabled. The port LED flashes yellow if the port tested faulty at startup.
Step 3 If a STATUS LED is red, contact a customer service representative for
instructions.
Step 4 If the boot information and system banner are not displayed, verify that the
terminal is set correctly and that it is connected properly to the console port.

Troubleshooting the Power Supply

Follow these steps to help isolate a power subsystem problem:
Step 1 Verify that the power supply is plugged in and that the on/off switch is set to ON
(if the power supply is an AC supply).
Troubleshooting the Power Supply
78-18039-02
Step 2 Look at the power supply LED (PS1 or PS2). If the LED is off or if the LED is
red, unplug the power cord, and then plug the power cord in. Be sure the on/off switch is OFF before removing the power cord from the power supply.
Step 3 If the LED remains off, there might be a problem with the AC or DC source or the
power cable.
Step 4 Connect the power cord to another power source if one is available. Step 5 If the LED then lights, the problem is the first power source. Step 6 If the LED fails to light after you connect the power supply to a new power source,
replace the power cord.
Step 7 If the LED still fails to light when the switch is connected to a different power
source with a new power cord, the power supply is probably faulty.
If you are unable to resolve the problem, contact a customer service representative for instructions.

Connecting to the Switch

Connecting to the Switch
You must use the console port to perform the initial configuration. To connect the switch console port to a PC, use the supplied RJ-45-to-DB-9 adapter cable.
Follow these steps to connect the PC or terminal to the switch:
Step 1 Using the supplied RJ-45-to-DB-9 adapter cable, insert the RJ-45 connector into
the console port that is located on the front of the switch, as shown in
Step 2 Attach the DB-9 female DTE of the adapter cable to a PC serial port, or attach an
appropriate adapter to the terminal.

Appendix B Initial Configuration for the Switch

Starting the Terminal-Emulation Software

Starting the Terminal-Emulation Software
Before you power on the switch, start the terminal-emulation session so that you can see the output display from the power-on self-test (POST).
The terminal-emulation software—frequently a PC application such as Hyperterminal or ProcommPlus—makes communication between the switch and your PC or terminal possible.
Step 1 Start the terminal-emulation program if you are using a PC or terminal. Step 2 Start a terminal-emulation session. Step 3 Configure the baud rate and character format of the PC or terminal to match these
console port default characteristics:
9600 baud
8 data bits
1 stop bit
No parity
None (flow control)

Connecting to a Power Source

Follow these steps to connect to a power source:
Step 1 If you are using an AC power supply, connect one end of the supplied AC power
cord to the power connector on the switch rear panel, and then connect the other end of the power cable to a grounded AC outlet. (See
Step 2 If you are using a DC power supply, see the “Connecting DC Power to the Switch”
section on page 3-11 for instructions on how to install the DC power supply.
As the switch powers on, it begins the POST, a series of tests that runs automatically to ensure that the switch functions properly.

POST lasts approximately 1 minute. After POST is complete, the system and status LEDs remain green (see the more information).
If the switch fails POST, the system LED turns amber.
Note POST failures are usually fatal. Call Cisco Systems if your switch does not pass
POST.
If you started the terminal-emulation program before you powered on your switch, the PC or terminal displays the bootloader sequence. Press Enter to display the setup program prompt.
