that is critical for the switch operation which could otherwise result in a switch being non-operational or causing permanent damage to the modules or components.

The following lists the features and functionalities of a Cisco Catalyst 9600 fan tray:

• Has nine individual fans (three rows of three each) and supports a minimum airflow of 720 cubic feet per minute (cfm) at 100 percent fan throttle.

• Has side-to-side airflow for balanced airflow across the inserted cards. When facing the front of the chassis, airflow direction is right to left.

• You can install and remove from the front and the rear.

• Has a built-in, front-facing, passive RFID tag that uses Ultra High Frequency (UHF) RFID technology and requires an RFID reader with a compatible software.

• Provides N+1 redundancy with individual fans. Fan tray does not support redundancy; however with N+1 redundancy using individual fans, system ensures that there is no impact to system performance even if one of the fans fail.

• Optimizes the fan-speed for temperature and pressure and maintains the minimum fan speeds and temperatures that the chassis requires, in ambient conditions.

The following figure shows C9606-FAN with the major components identified.

• If a single fan fails, the remaining fans in the row compensate with increased speed.

Cisco Catalyst 9600 Series Switches Hardware Installation Guide

Thresholds, Alarms, and Abnormal Acoustic Conditions

• If two or more fans fail, the entire fan tray operates at full speed after one minute. Further, the fan tray must be replaced. The individual fans are not field replaceable, you must replace the fan tray.

• If the temperature sensor fails or communication with the temperature sensor fails, the worst case operating temperature is assumed.

• If the pressure sensor fails or communication with the pressure sensor fails, the worst case operating pressure is assumed.

Thresholds, Alarms, and Abnormal Acoustic Conditions

Under normal operating conditions, when none of the temperature alarms have been triggered, hardware controls fan speed. If any of the system temperature alarms are triggered, software displays a syslog message indicating that the temperature is high and the fans are operating at higher speed. Refer to the System Management section of the software configuration guide for more information.

In case of a fan failure, you must replace the fan tray within 120 seconds or power down the system. If the temperature exceeds the shutdown threshold, software powers the system down.

When the fan tray operates at full speed, increased noise levels may be expected. The fan tray may operate at full speed in these circumstances:

Product Overview

• If two or more fans have failed

• If the STATUS LED remains red for more than one minute

• If there is a hardware failure

• If the software watchdog timer is triggered

Power Supply Module Overview

The switch chassis has four redundant power supply slots that operates with one to four power supply modules. The chassis supports field-replaceable AC-input and DC-input power supply modules.

The power supply modules generates 12Vdc output power and distributes it to the line cards and supervisor modules. The power supplies distribute power to all slots using an internal bus-bar based power distribution mechanism. All power supply modules have internal fans and support front-to-rear airflow.

The following are the supported power supply modules:

• Self-cooling, with a minimum airflow of 9.5 cubic feet per minute (CFM) at 100 percent load.

• Has a release latch mechanism on the side of the module, to avoid accidental removal of the module.

• Has DC-input reversal protection such that the unit will survive this condition up to the full input voltage rating.

• Supports redundant and combined configuration modes. A single (non-redundant) or a dual (redundant) power supply configuration, can support the following loads:

Voltage differential between inputs is unlimited.

Power Supply Modes

Cisco Catalyst 9600 Series Switches offer redundant and combined configuration modes for power supplies. In both the modes, the power supplies will share the load equally.

Power Supply Modes

Output PowerInput Voltage (VDC)

2000W-40 to -72VDC (with extended range to -75VDC)

Warning

The number of power supply modules installed and the system load determine the power-level that the system expects to draw from each power supply module and consequently, the power supply mode that will be suitable. For system power budgeting estimates and to determine power supply requirements, use the Cisco Power

Calculator.

To configure a power supply mode, enter the power redundancy-mode command in global configuration mode. If you do not configure a mode, the default mode applies.

Combined Mode

This is the default power supply mode.

The system operates with one to four power supply modules. The power available to the system is the sum of power outputs of all the power supply modules in the chassis multiplied by the share ratio. All available power supply modules are active and sharing power, and can operate at up to 100 percent capacity. Additional power supply units operate at 97 percent capacity. In combined mode, you can use a combination of AC and DC power supplies provided the AC input voltage is 220V and that the power supplies are of equal wattage. However, you cannot combine two AC power supplies of 110V input and 220V input.

Total combined mode power = P + (N-1) * P * (share ratio)

where P = Power output of one of the power supply units and N is the number of power supply modules used.

In case of failure in the combined mode, each operational power supply increases its output. If the output power does not meet system requirements, then all the operational power supply modules may be overloaded and go into overcurrent shutdown. All system power is then lost.

The following table provides details about the power output in combined mode:

Redundant (N+1) Mode

In a redundant configuration, a given power supply module can either be active, or in standby mode. In N+1 redundant mode, N is the number of active power supply modules and +1 is the power supply module configured as the standby module.

You can configure redundancy mode in the software. When the switch is configured with N+1 redundancy, software ensures that there is a standby power supply available and there is sufficient power available with the active power supply modules (N). All the power supplies including active and standby will share the load equally. . However, with a standby power supply installed, system ensures that the additional output power available with a standby is always reserved for use in case of a failure. If the power supply mode is set to redundant mode and the total active output power is not sufficient to meet the power requirements, the switch will not enter the redundant mode.

You can use a combination of AC and DC power supplies provided the AC input voltage is 220V and the power supplies must be of equal wattage. However, you cannot combine two AC power supplies of 110V input and 220V input.

Site Requirements

Planning a proper location for the switch and layout of the equipment rack or wiring closet is essential for successful system operation. These sections describe some of the basic site requirements that you should be aware of as you prepare to install your switch, including the following:

• Environmental factors can adversely affect the performance and longevity of your system.

• Install the switch in an enclosed, secure area, ensuring that only qualified personnel have access to the switch and control of the environment.

Temperature

• Equipment that is placed too closely together or that is inadequately ventilated may cause system over-temperature conditions, leading to premature component failure.

• Poor equipment placement can make chassis panels inaccessible and difficult to maintain.

• The switch 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 over-temperature condition may occur. The switch environmental monitor may then shut down the system to protect the system components.

• 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 air intake vent of the switch chassis.

Temperature extremes may cause a system to operate at reduced efficiency and cause a variety of problems, including premature aging and failure of chips, and failure of mechanical devices. Extreme temperature fluctuations may also cause chips to become loose in their sockets. Observe the following guidelines:

• Ensure that the system is operating in an environment that is—

• 23 to 113 °F (-5 to 45 °C) up to 6000 feet (1800m)

Cisco Catalyst 9600 Series Switches Hardware Installation Guide

Preparing for Installation

Air Flow

• 23 to 104 °F (-5 to 40 °C) up to 10000 feet (3000m)

• Ensure that the chassis has adequate ventilation.

• Do not place the chassis within a closed-in wall unit or on top of cloth, which can act as insulation.

• Do not place the chassis where it will receive direct sunlight, particularly in the afternoon.

• Do not place the chassis next to a heat source of any kind, including heating vents.

• Adequate ventilation is particularly important at high altitudes. Make sure that all the slots and openings on the system remain unobstructed, especially the fan vent on the chassis.

• Clean the installation site at regular intervals to avoid buildup of dust and debris, which may cause a system to overheat.

• If system is exposed to abnormally low temperatures, allow a two hour warm up period, in ambient temperature no lower than 32°F (0 °C) before turning on.

Warning

Air Flow

Do not operate the system if the fan assembly is removed or if it is not functioning properly. An overtemperature condition can cause severe equipment damage or an unscheduled system shutdown.

Failure to observe these guidelines may damage the chassis' internal components.

The switch is designed to be installed in an environment where there is a sufficient volume of air available to cool the supervisor engines, modules, and power supplies. If there are any constraints with regard to the free flow of air through the chassis, or if the ambient air temperature is elevated, the switch environmental monitor may then shut down the system to protect the system components.

To maintain proper air circulation through the switch chassis, we recommend that you maintain a minimum space of 6 inches (15 cm) between a wall and the chassis and power supply unit air intakes or a wall and the chassis and power supply unit hot air exhausts. In situations where the switch chassis are installed in adjacent racks, you should allow a minimum space of 12 inches (30.5 cm) between the air intake of one chassis and the hot air exhaust of another chassis.

Note

Failure to maintain adequate spacing between chassis may cause the switch chassis that is drawing in the hot exhaust air to overheat and fail.

Air Flow

Preparing for Installation

Figure 6: Air Flow Direction - Cisco Catalyst 9600 Series Switches

Chassis air exhaust3Chassis air intake1

Power supply air exhaust4Power supply air intake2

If you are installing your switch in an enclosed or partially enclosed rack, we strongly recommend that you verify that your site meets the following guidelines:

• Verify that there is a minimum of 6 inches (15 cm) of clearance between the sides, front, and back of any enclosure, and both the chassis air intake grill and the chassis air exhaust grill along with the power supply unit intakes and exhausts. The upright columns of a relay rack may be located less than the recommended side spacing provided there are substantial cutouts, holes, or vents in the structure to allow adequate air flow through the chassis.

• Verify that the ambient air temperature within the enclosed or partially enclosed rack is within the chassis operating temperature limits. After installing the chassis in the rack, power up the chassis and allow the chassis temperature to stabilize (approximately 2 hours).

Measure the ambient air temperature at the chassis air intake grill by positioning an external temperature probe 1 inch (2.5 cm) away from the chassis left side, and centered on the chassis both horizontally and vertically.

Cisco Catalyst 9600 Series Switches Hardware Installation Guide

Preparing for Installation

Humidity

Measure the ambient air temperature at the power supply unit air intake grill by positioning an external temperature probe 1 inch (2.5 cm) away from the chassis front, centered on the power supply unit section located above the card slots.

• If the ambient intake air temperature is less than 113°F (45°C) at altitudes of 6,000 feet and below, the rack meets the intake air temperature criterion. At altitudes above that threshold and up to 10,000 feet (3000 m), the air intake should not exceed 104°F (40°C).

• If the ambient intake air temperature exceeds this recommendation, the system may experience minor temperature alarms and increase fan speeds in response.

• If the ambient intake air temperature equals or is greater than 131°F (55°C), the system may experience a major temperature alarm with maximum fan speeds in response. If ambient temperature continues to increase, system will respond with protective shut down.

• Plan ahead. A switch that is currently installed in an enclosed or partially enclosed rack might meet ambient air temperature and air flow requirements at present. However, if you add more chassis to the rack or more modules to a chassis in the rack, the additional heat generated might cause the ambient air temperature at the chassis or power supply unit inlets to exceed recommended conditions which may trigger thermal alarms.

Humidity

High-humidity conditions may cause moisture to enter the system, and cause corrosion of internal components and degradation of properties such as electrical resistance, thermal conductivity, physical strength, and size. Extreme moisture buildup inside the system may result in electrical short circuit, which may cause serious damage to the system. Each system is rated for storage and operation in 10 to 95 percent relative humidity, non-condensing with a humidity gradation of 10 percent per hour. Buildings in which climate is controlled by air-conditioning in the warmer months and by heat during the colder months usually maintain an acceptable level of humidity for system equipment. However, if a system is located in an unusually humid location, a dehumidifier should be used to maintain the humidity within an acceptable range.

Altitude

Operating a system at high altitude (low pressure) reduces the efficiency of forced and convection cooling and may result in electrical problems related to arcing and corona effects. This condition may also cause sealed components with internal pressure, such as electrolytic capacitors, to fail or perform at reduced efficiency.

Dust and Particles

Fans cool power supplies and system components by drawing in room-temperature air and exhausting heated air out through various openings in the chassis. However, fans also ingest dust and other particles, causing contaminant buildup in the system and increased internal chassis temperature. A clean operating environment can greatly reduce the negative effects of dust and other particles, which act as insulators and interfere with the mechanical components in the system. The standards listed below provide guidelines for acceptable working environments and acceptable levels of suspended particulate matter:

• National Electrical Manufacturers Association (NEMA) Type 1

• International Electrotechnical Commission (IEC) IP-20

Cisco Catalyst 9600 Series Switches Hardware Installation Guide

Corrosion

Corrosion of system connectors is a gradual process that may eventually lead to intermittent failures of electrical circuits. The oil from a person’s fingers or prolonged exposure to high temperature or humidity may corrode the gold-plated edge connectors and pin connectors on various components in the system. To prevent corrosion, avoid touching contacts on boards and cards, and protect the system from extreme temperatures and moist, salty environments.

EMI and Radio Frequency Interference

Electro-Magnetic interference (EMI) and radio frequency interference (RFI) from a system can adversely affect devices such as radio and television (TV) receivers operating near the system. Radio frequencies emanating from a system can also interfere with cordless and low-power telephones. Conversely, RFI from high-power telephones can cause spurious characters to appear on the system monitor. RFI is defined as any EMI with a frequency above 10 kilohertz (kHz). This type of interference can travel from the system to other devices through the power cable and power source, or through the air in the form of transmitted radio waves. The Federal Communications Commission (FCC) publishes specific regulations to limit the amount of EMI and RFI emitted by computing equipment. Each system meets these FCC regulations. To reduce the possibility of EMI and RFI, follow these guidelines:

Preparing for Installation

• Always operate the system with the chassis covers installed.

• Ensure that all chassis slots are covered by a metal filler bracket and that an unused power supply bay has a metal cover plate installed.

• Ensure that the screws on all peripheral cable connectors are securely fastened to their corresponding connectors on the back of the chassis.

• Always use shielded cables with metal connector shells for attaching peripherals to the system.

When wires are run for any significant distance in an electromagnetic field, interference can occur between the field and the signals on the wires. This fact has two implications for the construction of plant wiring:

• Bad wiring practice can result in radio interference emanating from the plant wiring.

• Strong EMI, especially when it is caused by lightning or radio transmitters, can destroy the signal drivers and receivers in the chassis, and even create an electrical hazard by conducting power surges through lines into equipment.

Note

To predict and provide a remedy for strong EMI, consult experts in RFI.

If you use twisted-pair cable in your plant wiring with a good distribution of grounding conductors, the plant wiring is unlikely to emit radio interference. If you exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal when applicable.

Caution

Category 5e, Category 6, and Category 6a cables can store large levels of static electricity because of the dielectric properties of the materials used in their construction. Always ground the cables (especially in new cable runs) to a suitable and safe earth ground before connecting them to the module.

Cisco Catalyst 9600 Series Switches Hardware Installation Guide

Preparing for Installation

Shock and Vibration

If the wires exceed the recommended distances, or if wires pass between buildings, give special consideration to the effect of a lightning strike in your vicinity. The electromagnetic pulse caused by lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic devices. If you have had problems of this sort in the past, you may want to consult experts in electrical surge suppression and shielding.

Warning

The intra-building ports (Copper Based Ethernet Ports) of the equipment or subassembly is suitable for connection to intra-building or unexposed wiring or cabling only. The intra-building ports of the equipment or subassembly MUST NOT be metallically connected to interfaces that connect to the Out Side Plant (OSP) or its wiring for more than 6 meters (approximately 20 feet). These interfaces are designed for use as intra-building interfaces only (Type 2, 4, or 4a ports as described in GR-1089) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to an OSP wiring system.

Shock and Vibration

The equipment complies with the Earthquake, Office, and Transportation Vibration, and Equipment Handling Criteria of GR-63-CORE.

Power Source Interruptions

Systems are especially sensitive to variations in voltage supplied by the AC power source. Overvoltage, undervoltage, and transients (or spikes) can erase data from memory or even cause components to fail. To protect against these types of problems, power cables should always be properly grounded. Also, place the system on a dedicated power circuit (rather than sharing a circuit with other heavy electrical equipment). In general, do not allow the system to share a circuit with any of the following:

• Copy machines

• Air conditioners

• Vacuum cleaners

• Space heaters

• Power tools

• Teletype machines

• Laser printers

• Facsimile machines

• Any other motorized equipment

Besides these appliances, the greatest threats to a system's power supply are surges or blackouts that are caused by electrical storms. Whenever possible, turn off the system and peripherals, if any, and unplug them from their power sources during thunderstorms. If a blackout occurs—even a temporary one—while the system is turned on, turn off the system immediately and disconnect it from the electrical outlet. Leaving the system on may cause problems when the power is restored; all other appliances left on in the area may create large voltage spikes that may damage the system.

System Grounding

Preparing for Installation

Warning

Caution

When installing or replacing the unit, the ground connection must always be made first and disconnected last.

Statement 1046

Use copper conductors only. Statement 1025

You must install a system ground as part of the chassis installation process. Chassis installations that rely only on the AC third-prong ground are insufficient to adequately ground the systems.

Proper grounding practices ensure that the buildings and the installed equipment within them have low-impedance connections and low-voltage differentials between chassis. When you install a system ground, you reduce or prevent shock hazards, chances of equipment damage due to transients, and the potential for data corruption.

Without proper and complete system grounding, you run the risk of increased component damage due to ESD. Additionally, you have a greatly increased chance of data corruption, system lockup, and frequent system reboot situations by not using a system ground.

Installations that rely solely on system grounding that uses only an AC third-prong ground run a substantially greater risk of equipment problems and data corruption than those installations that use both the AC third-prong ground and a properly installed system ground.

The following table lists some general grounding practice guidelines.

Best grounding practices must be closely followed. Determine source and cause of noise if possible, and mitigate as closely as possible at the noise source or reduce coupling from the noise source to the victim equipment.

Best grounding practices should be followed as closely as possible. Electromagnetic noise problems are not anticipated, but installing a best-practice grounding system in a new building is often the least expensive route, and the best way to plan for the future.

Best grounding practices should be followed as much as possible. Electromagnetic noise problems are not anticipated, but installing a best-practice grounding system is always recommended.

Note

Caution

In all situations, grounding practices must comply with Section 250 of the National Electric Code (NEC) requirements or local laws and regulations. A 6 AWG grounding wire is preferred from the chassis to the rack ground or directly to the common bonding network (CBN). The equipment rack should also be connected to the CBN with a 6 AWG grounding wire.

Always ensure that all of the modules are completely installed and that the captive installation screws are fully tightened. In addition, ensure that all the I/O cables and power cords are properly seated. These practices are normal installation practices and must be followed in all installations.

Maintaining Safety with Electricity

When working on electrical equipment, follow these guidelines:

• Do not work alone if potentially hazardous conditions exist anywhere in your work space.

• Never assume that power is disconnected from a circuit; always check the circuit before working on it.

• Look carefully for possible hazards in your work area, such as damp floors, ungrounded power extension cables, frayed or damaged power cords, and missing safety grounds.

• If an electrical accident occurs, proceed as follows:

• Use extreme caution; do not become a victim yourself.

• Disconnect power from the system.

• If possible, send another person to get medical aid. Otherwise, assess the condition of the victim and then call for help.

• Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

Preparing for Installation

• Use the product within its marked electrical ratings and product usage instructions.

• Install the product in compliance with local and national electrical codes.

• If any of the following conditions occur, contact the Cisco Technical Assistance Center:

• The power cable or plug is damaged.

• An object has fallen into the product.

• The product has been exposed to water or other liquids.

• The product has been dropped or shows signs of damage.

• The product does not operate correctly when you follow the operating instructions.

• Use the correct external power source. Operate the product only from the type of power source indicated on the electrical ratings label. If you are not sure of the type of power source required, consult the Cisco Technical Assistance Center or a local electrician.

• Use approved power cables only. You have been provided with one or more power cables with your chassis power supply that are intended for use in your country, based on the shipping location. Should you need to purchase additional power cables, ensure that they are rated for the product and for the voltage and current marked on the product’s electrical ratings label. The voltage and current rating of the power cable should be greater than the ratings marked on the label.

• To help prevent electrical shock, plug all the power cables into properly grounded electrical outlets. These power cables are equipped with three-prong plugs to ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a power cable.

• Observe power strip ratings. Make sure that the total current rating of all products that are plugged into the power strip does not exceed 80 percent of the power strip rating.

• Do not modify power cables or plugs yourself. Consult with a licensed electrician or your power company for site modifications. Always follow your local and national wiring codes.

Preparing for Installation

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage may occur when modules or other FRUs are improperly handled, and result in intermittent or complete failure of the modules or FRUs. Modules consist of printed circuit boards that are fixed in metal carriers. EMI shielding and connectors are integral components of a carrier. Although the metal carrier helps to protect the board from ESD, always use an ESD-grounding strap when handling modules. To prevent ESD damage, follow these guidelines:

• Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.

• Connect the equipment end of the strap to an unfinished chassis surface.

• When installing a component, use any available ejector levers to properly seat the bus connectors in the backplane or midplane. These devices prevent accidental removal, provide proper grounding for the system, and help to ensure that bus connectors are properly seated.

• When removing a component, use any available ejector levers to release the bus connectors from the backplane or midplane.

• Handle carriers by available handles or edges only; avoid touching the printed circuit boards or connectors.

Preventing Electrostatic Discharge Damage

• Place a removed component board-side-up on an antistatic surface or in a static shielding container. If you plan to return the component to the factory, immediately place it in a static shielding container.

• Avoid contact between the printed circuit boards and clothing. The wrist strap only protects components from ESD voltages on the body; ESD voltages on clothing can still cause damage.

• Never attempt to remove the printed circuit board from the metal carrier.

Power Requirements

Power supplies installed on the switch chassis can be all AC-input, all DC-input, or a mix of both. When preparing your site for switch installation, adhere to these requirements:

• In systems configured with more than one power supply, connect each of the power supplies to a separate input power source. If you fail to do this, your system might be susceptible to total power failure due to a fault in the external wiring or a tripped circuit breaker

• To prevent loss of input power, be sure that the total maximum load on each source circuit is within the current ratings of the wiring and breakers.

• In some systems, you may decide to use an uninterrupted power supply (UPS) to protect against power failures at your site. Be aware when selecting a UPS that some UPS models that use ferroresonant technology may become unstable when operating with the switch power supplies that use power factor correction. This may cause the output voltage waveform to the switch to become distorted, resulting in an undervoltage situation in the system.

Cabling Requirements

When running power and data cables together in overhead cable trays or subfloor cable trays, be aware of the following caution:

Rack-Mounting Guidelines

Preparing for Installation

Caution

We strongly recommend that power cabling runs and other potential noise sources be located as far away as practical from LAN cabling that terminates on Cisco equipment. In situations where this type of long parallel cable runs exist and cannot be separated by at least 3.3 feet (1 meter), we recommend that you shield these potential noise sources. To avoid interference, the source should be shielded by housing it in a grounded metallic conduit.

Also be aware of the following caution concerning the use of Category 5e and Category 6 Ethernet cables:

Rack-Mounting Guidelines

Rack Specifications

Cisco Catalyst 9600 Series Switches are designed to be installed in standard, 19-inch equipment racks that meet EIA-310-D specifications. In Network Equipment Building Systems (NEBS) compliant installation, you can use only a 23-inch rack mount. Before rack-mounting the chassis, ensure that the equipment rack complies with all requirements and guidelines

Mounting Location Guidelines

Cisco Catalyst 9600 Series Switches must be front-mounted.

Accordingly, you can install the chassis in 2-post or 4-post racks, but in a 4-post rack, the rear posts are not used for mounting.

Width and Depth Requirements

Use a tape measure to verify the interior dimensions of the rack.

• Measure the space between the inner edges of the left front and right front mounting posts. The chassis is 19 inches (48.26 cm) wide and must fit between the mounting posts.

• Measure the depth of the rack from the outside of the front mounting posts to the outside of the rear mounting strip. The chassis is 18.8 inches (47.75 cm) deep.

Height Requirements

The rack must have sufficient clearance in terms of height, to insert the chassis. Chassis height is also measured in rack units (RU or just U) where 1 RU or 1 U equals 1.75 inches (44.45 mm). A typical server rack is 42 RU or 42 U in height.

The chassis height of Catalyst 9606R Switch is 8 RU with a depth of 18.8 inches.
