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 inform ation 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 five fans in the fan tray. If an individual fan fails, the other fans continue to run. Sensors
monitor the internal air temperatures. The number of fans in operation and their speed varies according
to the internal temperature for the quietest operation possible. If the air temperature exceeds a desired
threshold, the environmental monitor displays warning messages.

Note Individual fans in the fan tray cannot be replaced; the entire fan tray must be replaced.

Power Supplies

Note For complete power specifications for the Catalyst 4900M switch, see Appendix A, “Specifications.”

The Catalyst 4900M switch has two redundant internal 1000 W AC-input or 1000 W DC-input 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 AC source. There
is a power switch on the AC-input 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-input power supplies attach to source
DC using customer-supplied cables.

The switch starts with only one power supply plugged in, but redundant failover and load sharing is not
available in this configuration. Cisco recommends that you always connect both power supplies to
separate AC or DC circuits for optimal power reliability.

78-18350-02

Cisco Catalyst 4900M Switch Installation Guide

1-7

Catalyst 4900M Half-Card Modules

For safety reasons, the AC power supply must 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 is used, you must use the supplied blank faceplate to cover the empty power
bay. The blank power supply cover maintains EMI shielding and proper air flow through the chassis.

Environmental Monitoring of the Power Supplies

Using the environmental monitoring and reporting functions, you can maintain normal system operation
by resolving adverse environmental conditions prior to loss of operation.

Each power supply monitors its own temperature and output voltages. The Catalyst 4900M switch senses
the operating condition of the power supply and reports status through software.

Power Management for the Catalyst 4900M Switch

You can select either AC-input or DC-input power supplies for your switch. The Catalyst 4900M switch
supports the following power supplies:

Chapter 1 Product Overview

• 1000 W AC-input

• 1000 W DC-input

A redundant power supply can be identified and diagnosed by a running system regardless of its input
status. The AC-input and DC-input supplies are interchangeable.

Power Management Modes

The Catalyst 4900M switch supports the redundant power management mode. In this mode, if both
power supplies are operating normally, each provides from 20/80 to 45/55
power requirements at all times. If one power supply fails, the other unit increases power to 100
of the total power requirement.

Catalyst 4900M Half-Card Modules

The Catalyst 4900M switch chassis has two half-card slots available allowing two half-card modules to
be installed. The following half-card modules are available:

Note TwinGig converter modules may be installed in place of X2 transceiver modules if you need 1-GB SFP

transceiver connections. When you insert the TwinGig into one port, its neighbor port automatically
converts to 1 GE interfaces whether it has a TwinGig installed or not, so you must position your TwinGig
converters next to each other. The neighboring port to a TwinGig port cannot support an X2. Installation

Note When using TwinGig converters and X2 transceivers on this module, keep them grouped in pairs as

follows: ports

1–2, ports 3–4, ports 5–6 and ports 7–8. Inserting a TwinGig converter or X2 transceiver
in any port will affect the capability of its neighbor port, and both will be set to handle the same type
automatically. Mixing within a port group does not work. As an example, you would not be able to have
an X2 transceiver in port 1 and a TwinGig converter in port 2.

Site Planning

This chapter describes how to prepare your site for installation of the Catalyst 4900M switch and
contains these sections:

• Site Environmental Requirements, page 2-1

• Site Power Requirements, page 2-2

• Grounding Requirements, page 2-7

• Safety Overview, page 2-7

• Site Planning Checklist, page 2-9

Note A site planning checklist is provided on page 2-8 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.

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.

78-18350-02

Cisco Catalyst 4900M Switch Installation Guide

2-1

Site Power Requirements

Cooling air is drawn in through the right side and exhausted through the left side 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
Appendix A are 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.

Site Power Requirements

This section describes the installation site power requirements for the Catalyst 4900M switch. Verify
your site power before you install the switch.

This section consists of the following sections:

• Preinstallation Requirements, page 2-2

Chapter 2 Site Planning

• Warnings and Cautions, page 2-2

• EMI Recommendations, page 2-3

• Power Requirements and Heat Dissipation, page 2-3

Preinstallation Requirements

Follow these requirements when preparing your site for the Catalyst 4900M switch installation:

• Connect each switch to separate wiring on a dedicated circuit; provide each switch with its own

branch circuit connection with sufficient overcurrent protection and direct grounding to the branch
circuit.

• To prevent a loss of input power, be sure the total maximum load on each AC circuit is within the

current ratings of the wiring and breakers.

Warnings and Cautions

Follow these precautions when preparing your site for the Catalyst 4900M switch installation:

Caution The total maximum load on each AC or DC -input power circuit must be within the rating of the wiring

and breaker. An overload of input power can result if this requirement is not met.

Ultimate disposal of this product should be handled according to all national laws and regulations.

Statement 1040

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.

Power Requirements and Heat Dissipation

The power requirements might be useful for planning the power distribution system needed to support
the switches. Heat dissipation is an important consideration for sizing the air-conditioning requirements
for an installation. Refer to

Appendix A, “Specifications,” for the power and heat ratings for a

Catalyst 4900M switch.

You will also need to provide power to the switch with the appropriate AC power cord for your location.

Table 2-1 lists the specifications for the AC power cords that are available for the 1000 W AC-input

power supply. The table includes references to illustrations of the AC power cords.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage occurs when electronic cards or components are improperly
handled and can result in complete or intermittent failures. Follow these guidelines to prevent ESD
damage:

• Always use an ESD-preventive wrist or ankle strap, and ensure that it makes maximum contact with

the skin.

• When coming into contact with any internal components, always use a wrist strap connected to one

of the following:

–

ESD wrist strap connector

–

Any unpainted grounded surface on the chassis or equipment rack

Caution Periodically check the resistance value of the antistatic strap. The measurement should be between 1 and

10 megohms (Mohms).

• Handle cards by the edges only.

Site Planning Checklist

• Avoid contact between the modules and clothing. The wrist strap protects only the card from ESD

voltages on the body; ESD voltages on clothing can still cause damage.

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.

Statement 1006

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 inches
(45.09

cm).

–

The depth of the rack, between the front and rear mounting strips, must be at least 19.25 inches
(48.9

cm) but not more than 32.5 inches (82.5 cm).

Note If your four-post rack enclosure exceeds 32.5 inches (82.5 cm) in depth, or you are

installing the chassis in a two-post equipment rack, you must order and use the optional
rack-mount kit (C4900M-BKTS-KIT=).

Cisco Catalyst 4900M Switch Installation Guide

78-18350-02

Chapter 3 Installing the Switch

• The equipment rack is stable and in no danger of falling over.

• The equipment rack is properly ventilated.

Rack-Mounting the Switch

–

The rack must have sufficient vertical clearance to insert the chassis. The chassis height is 2 U
(3.5

inches (8.9 cm)).

–

Ensure that the shelf is constructed to support the weight and dimensions of the chassis. For
physical specifications, see

–

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

Appendix A, “Specifications.”

prevent the rack from becoming top-heavy and tipping over.

–

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.

–

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.

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.

78-18350-02

Cisco Catalyst 4900M Switch Installation Guide

3-3

Rack-Mounting the Switch

• 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.

• Always disconnect all external cables before lifting or moving the chassis.

Required Installation Tools

The following tools and equipment are required to install the chassis:

• Number 1, number 2 Phillips, and 3/16-inch flat-blade screwdriver

• Antistatic mat or antistatic foam

• Your own ESD grounding strap or the disposable ESD strap included with the system

The following tools and equipment are required to install the chassis in a rack:

• Rack-mount kit

• Tape measure and level

Chapter 3 Installing the Switch

Rack-Mounting the Catalyst 4900M Switch

Follow these steps to install the Catalyst 4900M switch in a four-post rack.

Step 1 Prepare for installation:

a. Place the chassis on the floor or on a sturdy table as close as possible to the rack. Leave enough

clearance to allow you to move around the chassis.

b. Use a tape measure to measure the depth of the rack. Measure from the outside of the front mounting

posts to the outside of the rear mounting strip. The four-post rack depth must be at least 19.25
(48.9

cm) but not more than 32.5 inches (82.5 cm). If the 4-post rack depth is greater than

32.5

inches (82.5 cm), order and use the optional rack-mount kit (C4900M-BKTS-KIT=).

c. Measure the space between the inner edges of the left front and right front mounting posts to ensure

that it is 17.75
between the mounting posts.)

d. Open the standard rack-mount kit, and refer to Tab l e 3-1 to verify that all parts are included.

Troubleshooting the Installation

This chapter describes how to troubleshoot the Catalyst 4900M switch hardware installation and
contains these sections:

• Getting Started, page 4-1

• Problem Solving to the System Component Level, page 4-2

• Identifying Startup Problems, page 4-2

• Troubleshooting the Power Supply, page 4-4

• Contacting Customer Service, page 4-4

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.

Note For configuration questions or problems, refer to the software configuration guide or the command

reference publication to configure or enable the interfaces.

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.

Chapter 4 Troubleshooting the Installation

Problem Solving to the System Component Level

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.

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 4-4.)

• 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.

Identifying Startup Problems

When you connect the power cords to the Catalyst 4900M 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

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

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:

Step 1 Compare the LED states to those listed in Table 4-1.

“Troubleshooting the Power Supply” section on page 4-4.

OUTPUT OK Green—DC output voltages are within the normal

operating range.

Red—Output voltages below the minimum or above the
maximum will create an output fail alarm and cause the
LED to illuminate red.

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.

• 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

Troubleshooting the Power Supply

To help isolate a power subsystem problem, perform the following steps:

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).

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.

Chapter 4 Troubleshooting the Installation

If you are unable to resolve the problem, contact a customer service representative for instructions.

Contacting Customer Service

If you are unable to solve a startup problem after using the troubleshooting suggestions in this chapter,
contact a customer service representative for assistance and further instructions. Before you call, have
the following information ready to help your service provider assist you as quickly as possible:

• Date you received the switch

• Chassis serial number (located on a label on the right of the rear of the chassis, see Figure 4-1)

• Type of software and release number
