Chassis Cooling

The hot-swappable chassis fan tray (WS-X4992) provides cooling air for the internal ch assis components. The fans draw air in from the right side of the chassis and exhaust the heated air through perforations on the right side of the chassis.

Caution When the fan tray is removed, internal circuitry is exposed that should not be touched by tools or fingers.

The system should not operate without a fan tray for longe r than i s necessar y to repl ace a fau lty fan tray with a new fan tray.

Figure 1-4 shows the direction of airflow through the switch.

Figure 1-4 Catalyst 4900M Chassis Airflow

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 plug ged in, bu t redu ndant failove r and load sha ring 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.

Page 24

Catalyst 4900M Half-Card Modules

For safety reasons, the AC power supply must be s witched off and unplugged before it is remove d 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 C atalyst 4900M swit ch senses the operating condition of the power supply and reports status through software.

Power Management for the Cataly st 4900M Switch

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

• 1 000 W AC-input

• 1 000 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 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.

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:

• WS -X4920-GB-RJ45 Hal f-Card Ethernet Mod ule, page 1-9

• WS -X4904-10GE Half-C ard Ethernet Module, pa ge 1-10

• WS -X4908-10GE Half-C ard Ethernet Module, pa ge 1-11

• WS -X4908-10G -RJ45 Half -Card E thernet Module, page 1-13

The half-card modules can be mixed in a chassis.

Site Planning

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

• Site Envir onmental Requireme nts, page 2-1

• Site Power Requirements, page 2-2

• Groundin g Requirements , page 2-7

• Saf ety O vervi ew, pag e 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 r ack or w iring closet i s essenti al 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 i s placed too closely together or that is inadequately ventilated can cause system overtemperature conditions. In addition, poor equipment placement c an make cha ssis pa nels inacce ssible a nd 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.

Site Power Requirements

Cooling air is drawn in through the right side and exhausted through the left side of the chassis. Ke ep 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 l isted 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

• Warni ngs and Cautions, page 2-2

• E MI Recommendations, pa ge 2-3

• Power Requirements and Heat Dis sipation, 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 r ating of the wiring

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

Warning

Read the installation instructions befor e con nectin g the system to the power s ource.

Warning

Installation of the equipment must comply with local and national ele ctrical code s.

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 interfer ence.

• 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 Di ssipation

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 Dama ge

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 antista tic strap. The measu rement should be between 1 and

10 megohms (Mohms).

• Handle card s by the edges only.

• 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.

Rack-Mounting the Switch

A rack-mount kit (69-1821-03) is included in the accessory kit for mounting the switch i n a standard 19-inch (48.3 cm) four-post equipment rack where the depth of the rack (the distance measured between the front and the rear posts) does not exceed 32.5 inches (82.5 cm). This rack-mount kit is not suitable for racks with obstructions (such as a power strip) that could impair access to the switch, four-post rack enclosures that exceed 32.5 inches (82.5 cm) in depth, or for two-post equipment racks.

An optional rack-mounting kit (C4900M-BKTS-KIT=) is available for installing the chassis in two-post telco racks and in four-post equipment ra cks that exceed 32.5 inches (82.5 cm) in depth.

Caution Before installing the chassis in a rack, read the “Site Environmental Requirements” section on page 2-1

to become familiar with the proper site and environmental conditions. Failure to read and follow these guidelines could lead to an unsuccessful installation and possible damage to the system and components.

Caution This unit is meant to be rack-mounted, and is not intended to bear more than its own weight. Do not stack

more than two on a table top, the added weight may damage the bottom chassis.

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 guide lines are prov ided 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 botto m of the r ac k.

• If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in

Statement 1006

the rack.

Rack-Mounting Guidelines

Before rack-mounting the switch, ensure the following:

• T he equipment rack is the prope r 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 m ust or der and us e the optiona l rack-mount kit (C4900M-BKTS-KIT=).

Chapter 3 Installing the Switch

78-18350-02

Page 43

Chapter 3 Installing 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)).

• 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.

–

Install the stabilizers before mounting or servicing the switch in the rack (if the rack is provided with stabilizing devices).

• The equipment rack is properly ventilated.

–

Install the chassis in an enclosed rack only if it has adequate ventilation or an exhaust fan; use an open rack whene ver pos sibl e.

–

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 r ack.

–

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:

• Ensu re that your footing is soli d, and balance the weight of the chassis between your fee t.

• Lift the chassis slowly; never move suddenly or twist your body as you lift.

• Kee p 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.

• Al ways disconnect all exte rnal cables before liftin g 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 ow n ESD grounding strap o r the disposa ble E SD strap included with the syste m

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

• Ra ck-mount k it

• Tape measu re and level

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.Pl ace 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 th e 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 r ack depth mus t be at least 1 9.25 inch es (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=).

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

• Identif ying Startup Probl ems, page 4-2

• Troubles hooting the Power Supply, page 4-4

• Conta cting Custo mer Se rvice, pa ge 4-4

If your system has problems starting up, use the information in this chapter to help isolate the caus e. 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 softw are configuration guid e or the command

reference publication to configure or enable the interfaces.

Getting Started

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

• Power suppli es are supplying power to the system.

• The system fan assembly is operating.

• System sof tware boots successf ully.

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 softw are. 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

Problem Solving to the System Compon ent 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—In cludes th e power suppl y and power sup ply cooli ng. (See the “Troubleshooting t he

Power Supply” section on page 4-4.)

• Fan assembly syste m—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 immedi ately hear the system fan as sembly begin to

operate, see “Troubleshooting the Power Supp ly” section on page 4-4.

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.

Table 4-1 Power Supply LED Meanings

LED M eaning

INPUT OK (AC) This LED should turn green immediately when power is

applied to the supply and the power switch is set to ON.

Green—AC input voltage is greater than 80.5 VAC ±4.5 VAC.

Red—In a dual power supply configuration (alternate unit powered) the AC input is less than 73 VAC ±3 VAC, or the power supply is turned off.

Off—In a single supply configuration, signals that AC input voltage is less than 73 VAC ±3 VAC, or th e p ow e r supply is turned off.

INPUT OK (DC) This LED should turn green immediately when power is

applied to the supply.

Green—DC input voltage is greater than –38.25 VDC ±2.25 VDC.

Red—In a dual power supply configuration (alternate unit powered) the DC input is less than 33 VDC ±3 VDC, or the power supply is turned off.

Off—In a single supply configuration, the LED shall be off to signal that DC input is less than 33 VDC ±3 VDC, or t he power supply is turned off.

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

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 LE D is red, unplug the power

cord, and then plug the power cord in. Be sure the on/off switch is OFF befo re removin g the p ower 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.

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 possibl e:

• 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 sof tware and release number

• Maintenance agreement or warranty information

• Br ief description of the pr oblem

• Br ief explanation of the ste ps you have already taken to isol ate and resolve the proble m
