SFP and SFP+ Transceiver Module Ports

The chassis contain 16 ports of 10-Gigabit Ethernet SFP+ or 100BASE-FX fiber-optic transceiver modules. All ports support 1-Gigabit SFP, 10-Gigabit SFP+, or 100BASE-FX fiber-optic SFP modules.

The ports also support Cisco Trust Security (CTS) and virtual switch link (VSL) and can operate as an Instant Access (AI) Parent in both 1-Gigabit and 10-Gigabit modes.

The SFP and SFP+ transceiver modules provide copper or fiber-optic connections to other devices. These transceiver modules are field-replaceable and provide the uplink interfaces when installed in an SFP module slot. The SFP transceiver modules have LC connectors for fiber-optic connections or RJ-45 connectors for copper connections.

Management Port

The management port is a 10/100/1000 copper Ethernet port directly connected to the route processor. With an network interface card (NIC) interface, it supports TFTP image downloading, network management, SNMP, Telnet, and SSH connections. The management port is isolated from other ports in the system; it is not part of the EARL forwarding logic. The management port provides direct access to the CPU, even when the system is heavily loaded.

The management port is a Layer 3 port in host mode, and only accepts traffic that terminates on the router. This port does not route packets between itself and other ports. The port processes only the following packet types and properly enqueues them:

•

Management Port

Address Resolution Protocol (ARP)

IPv4 unicast

Related Topics

USB Port Type B

The USB 2.0 port Type B serves as a second console connection to the route processor. The USB console port connection uses a USB Type A to Type B cable. The USB console interface speeds are the same as the RJ-45 console interface speeds. Windows PCs need a driver for the USB port.

The USB-prefer mode is the default, but it can be overridden using the command-line interface (CLI). When this port is in USB-prefer mode, the RJ-45 console port will be disabled if both ports are connected. For more information on using the CLI to configure the USB console interface, see the Catalyst 6500 software guide.

The fan tray is responsible for cooling the entire chassis and interfacing with environmental monitors to trigger alarms when conditions exceed thresholds. The fan tray supports Online Insertion and Removal (OIR).

The fan tray contains four high-efficiency fans with variable speed settings and thermal sensors. If one fan fails, the speed of the others is increased and a minor alarm is triggered. If a major fan tray failure occurs, the system is shut down. The individual fans are not field replaceable; the entire fan tray must be replaced in the event of a major fan tray failure. See Removing the Fan Tray, on page 73 for additional information about the fan.

Safety Warnings

Safety warnings appear throughout this publication in procedures that might harm you if performed incorrectly. The warnings below are general warnings that are applicable to the entire publication.

CHAPTER 2

Warning

Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030

This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security. Statement 1017

Read the installation instructions before connecting the system to the power source. Statement 1004Warning

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.

•

OL-30827-02 17

Page 30

Temperature

Preparing for Installation

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 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

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 no colder than 32°F (0°C) or no hotter than 104°F

•

(40°C).

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 the system has been exposed to abnormally cold temperatures, allow a 2-hour warm-up period to bring

•

it to normal operating temperature before turning it on.

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

Note

The Catalyst 6880-X switches are equipped with internal air temperature sensors that trigger a minor alarm at 104°F (40°C) and trigger a major alarm at 131°F (55°C).

Catalyst 6880-X Switch Hardware Installation Guide

Page 31

Preparing for Installation

Air Flow

The Catalyst 6880-X switch is designed to be installed in an environment where there is a sufficient volume of air available to cool the baseboard and other boards in the chassis, any installed modules, and power supplies. Any constraints placed on the free flow of air through the chassis or an elevated ambient air temperature can cause the switch to overheat and shut down.

To maintain proper air circulation through the Catalyst 6880-X switch chassis, maintain a minimum 6-inch (15 cm) separation between a wall and the chassis air intake or a wall and the chassis hot air exhaust. In situations where the switch chassis are installed in adjacent racks, you should allow a minimum of 12 inches (30.5 cm) between the air intake of one chassis and the hot air exhaust of another chassis. Failure to maintain adequate spacing between chassis can cause the switch chassis that is drawing in the hot exhaust air to overheat and fail.

If you are installing your Catalyst 6880-X 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 of the rack and both

•

the chassis air intake grill and the chassis air exhaust grill.

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 and at the chassis air exhaust grill by positioning an external temperature probe approximately 1 inch (2.5 cm) away from the grills.

If the ambient intake air temperature is less than 104°F (40°C), the rack meets the intake air temperature

•

criterion.

If the ambient intake air temperature exceeds 104°F (40°C), the system might experience minor

◦

temperature alarms and is in danger of overheating.

If the ambient intake air temperature equals or is greater than 131°F (55°C), the system will

◦

experience a major temperature alarm and shut down.

Verify that the enclosed or partially enclosed rack allows an adequate flow of air through the switch

•

chassis as follows:

If the difference between the measured intake air temperature and the exhaust air temperature does

◦

not exceed 10°C, there is sufficient airflow in the rack.

If the difference in air temperature exceeds 10°C, there is insufficient airflow to cool the chassis.

◦

Note

The 10°C temperature differential between the intake and the exhaust must be determined by taking measurements using external digital temperature probes. Do not use the chassis internal temperature sensors to measure the temperature differential.

Plan ahead. Your Catalyst 6880-X switch that is installed in an enclosed or partially enclosed rack might

•

currently meet ambient air temperature and air flow requirements. However, if you add more chassis to the rack or you add more modules to a chassis in the rack, the additional heat generated might cause the ambient air temperature within the rack to exceed 104°F (40°C) and can cause minor alarms.

Cooling with the Fan Tray

The chassis fan tray provides cooling air for the Catalyst 6880-X switch chassis and components. If an individual fan within the fan tray fails, the Fan Status LED turns red. Individual fans within a fan tray cannot be replaced; you must replace the entire fan tray.

Refer to your software configuration guide for information on environmental monitoring.

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 to operate at 5 to 90 percent relative humidity, with a humidity gradation of 10 percent per hour. In storage, a system can withstand 5 to 95 percent relative humidity. 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.

Catalyst 6880-X Switch Hardware Installation Guide

Page 33

Preparing for Installation

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. The Catalyst 6880-X switch is rated to operate at altitudes from 0 to 6500 feet (0 to 2000 meters) and can be stored at altitudes of –200 to 10,000 feet (–60 to 3000 meters).

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:

Altitude

National Electrical Manufacturers Association (NEMA) Type 1

•

International Electrotechnical Commission (IEC) IP-20

•

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

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:

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.

OL-30827-02 21

Catalyst 6880-X Switch Hardware Installation Guide

Page 34

Power Source Interruptions

•

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:

•

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

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.

Preparing for Installation

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

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.

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.

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.

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

Preparing for Installation

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

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.

System Grounding

Caution

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.

Grounding RecommendationsElectromagnetic Noise

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.

In installations where FXS modules are installed, supplemental grounding is required.Note

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.

Maintaining Safety with Electricity

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

•

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

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when modules or other FRUs are improperly handled, results in intermittent or complete failures. Modules consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the 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 strap and ensure that it makes maximum contact with bare skin. ESD grounding

•

straps are available with banana plugs, metal spring clips, or alligator clips. All Catalyst 6880-X chassis are equipped with a banana plug connector (identified by the ground symbol next to the connector) somewhere on the front panel. If you have an older Catalyst 6880-X chassis equipped with a plastic banana plug connector, it is recommend that you use either the supplied ESD grounding wrist strap (with a metal clip) or an ESD grounding wrist strap equipped with an alligator clip. If you have a newer Catalyst 6880-X chassis that has a bare metal hole as the banana plug connector (also identified by the ground symbol next to the connector), we recommend that you use a personal ESD grounding strap equipped with a banana plug.

Preparing for Installation

If you choose to use the disposable ESD wrist strap supplied with most FRUs or an ESD wrist strap

•

equipped with an alligator clip, you must attach the system ground lug to the chassis in order to provide a proper grounding point for the ESD wrist strap.

If your chassis does not have the system ground attached, you must install the system ground. See

•

Establishing the System Ground, on page 45 for installation instructions and locations of the chassis

system ground pads.

Attaching the ESD Wrist Strap

After you install the system ground lug, follow these steps to correctly attach the ESD wrist strap:

Procedure

Step 1

Step 2

Secure the ESD wrist strap equipped with an alligator clip to your bare skin.

Grasp the spring or alligator clip on the ESD wrist strap and momentarily touch the clip to a bare metal spot (unpainted surface) on the rack. It is recommend that you touch the clip to an unpainted rack rail so that any built-up static charge is then safely dissipated to the entire rack.

Step 3

Attach the alligator clip directly over the head of the system ground lug screw or to the system ground lug barrel.

Figure 11: Attaching the ESD Wrist Strap to the System Ground Lug Screw

Power Requirements

When preparing your site for the switch installation, follow these requirements:

When installing two power supplies, connect each power supply 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 a 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.

You might decide to use an uninterruptible 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 can become unstable when operating with the Catalyst 6880-X switch power supplies which use power factor correction (PFC). This can cause the output voltage waveform to the switch to become distorted resulting in an undervoltage situation in the system.

The AC-input power supply has a detachable power cord that allows you to connect each power supply

•

to the site power source.

You can connect the DC-input power supply to the power source with heavy-gauge wiring connected

•

to a terminal block. The wire gauge size is determined by local electrical codes and restrictions.

If you are using a 200/240 VAC power source in North America, the circuit must be protected by a

•

two-pole circuit breaker.

The source AC outlet must be within 6 feet (1.8 meters) of the system and should be easily accessible.

•

Power Connection Guidelines for DC-Powered Systems

This section provides the basic guidelines for connecting the Catalyst 6880-X switch DC-input power supplies to the site power source:

All power connection wiring should conform to the rules and regulations in the National Electrical Code

•

(NEC), as well as any local codes.

The DC return must remain isolated from the system frame and the chassis (DC-I).

•

For DC power cables, we recommend that you use commensurately rated, high-strand-count copper

•

wire cable. Connection to the DC-input power supply requires one earth ground cable, one source DC (–), and one source DC return (+). The length of the cables depends on your switch location. These cables are not available from Cisco Systems. They are available from any commercial cable vendor.

The color coding of the source DC power cable leads depends on the color coding of the site DC power

•

source. Typically, green or green and yellow indicate that the cable is a ground cable. Because there is no color code standard for source DC wiring, you must ensure that the power cables are connected to the DC-input power supply terminal block in the proper (+) and (–) polarity. In some cases, the source DC cable leads might have a positive (+) or a negative (–) label. This label is a relatively safe indication of the polarity, but you must verify the polarity by measuring the voltage between the DC cable leads. When making the measurement, the positive (+) lead and the negative (–) lead must always match the (+) and (–) labels on the DC-input power supply terminal block.

DC power cables must be terminated by cable lugs at the power supply end.

•

Catalyst 6880-X Switch Hardware Installation Guide

28 OL-30827-02

Page 41

Preparing for Installation

The circuit breaker is considered to be the disconnect device and should be easily accessible.

•

The circuit must be protected by a dedicated two-pole circuit breaker. The circuit breaker should be

•

sized according to the power supply input rating and local or national code requirements.

For proper DC-input redundant power configurations on systems with multiple-input DC-input power

•

supplies, all pairs of source DC cables for one DC-input power supply must come from the same battery system (A feed); all pairs of source DC cables for the second DC-input power supply must come from a different battery system (B feed).

For DC-input power supplies with multiple inputs, each DC input must be protected by a dedicated

•

circuit breaker or a fuse. The circuit breaker or the fuse must be sized according to the power supply input rating and local or national electrical codes.

Cabling Requirements

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

Cabling Requirements

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:

Establishing the System Ground

This section describes how to connect a system ground to the Catalyst 6880-X switch.

Establishing the System Ground

Caution

Note

Installations that rely solely on system grounding using 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 system ground provides additional grounding for EMI shielding requirements and grounding for the low voltage supplies (DC-DC converters) on the modules. You must observe the following system grounding guidelines for your chassis:

You must install the system ground connection with any other rack or system power ground connections

•

that you make. The system ground connection is required if FXS modules are installed or if this equipment is installed in a U.S. or European Central Office.

You must connect both the system ground connection and the power supply ground connection to an

•

earth ground. The system ground connection is required if FXS modules are installed or if this equipment is installed in a U.S. or European Central Office.

When using DC-input power supplies, you must install the system (ground before you attach the source

•

DC power cables to the DC PEM. Power down the chassis before attaching the system ground.

Note

The system ground serves as the primary safety ground for chassis that are equipped with DC-input power supplies. The DC-input power supplies for these chassis do not have a separate ground.

Required Tools and Equipment

To connect the system ground, you need the following tools and materials:

• Grounding lug—A two-hole standard barrel lug. Supports up to 6 AWG wire. Supplied as part of

accessory kit.

• Grounding screws—Two M4 x 8 mm (metric) pan-head screws. Supplied as part of the accessory kit.

• Grounding wire—Not supplied as part of accessory kit. The grounding wire should be sized according

to local and national installation requirements. Depending on the power supply and system, a 12 AWG to 6 AWG copper conductor is required for U.S. installations. Commercially available 6 AWG wire is recommended. The length of the grounding wire depends on the proximity of the switch to proper grounding facilities.

No. 1 Phillips screwdriver.

Verifying Switch Chassis Installation

Procedure

Verifying Switch Chassis Installation

Step 1

Step 2

Verify that all empty module slots have blank faceplates installed and that the screws holding the plates in place are tight. The blank faceplates optimize the air flow through the chassis and contain electromagnetic interference.

Warning

Turn on the power supply switches to power up the system. During the power-up sequence, the system performs a series of bootup diagnostic tests.

Additional system diagnostic tests are available. These tests allow you to perform a complete sanity check on the system prior to inserting the system into your network and to monitor the health of the system while the system is running. Refer to the “Online Diagnostics” section on page 3-19 for further information.

When prestaging systems in a nonproduction environment, we recommend that you run all diagnostic

Tip

tests, including the disruptive tests, to prescreen the systems for any failures.

Online Diagnostics

The switch running Cisco IOS has many levels of online diagnostic capabilities. The online diagnostics are divided into four categories:

Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029

• Bootup—Bootup diagnostics automatically run during bootup, module OIR, or switchover to a backup

supervisor engine.

• Background health—Monitoring diagnostic tests are continuously run by the system to monitor system

health.

• On-demand online diagnostics—On-demand online diagnostics can be used to run any test from the

CLI. You can also run on-demand online diagnostics to perform a sanity check on the system hardware. Some of these tests are disruptive and will impact traffic flow.You must follow the on-demand diagnostic guidelines exactly to avoid false failures.

• Scheduled diagnostics—Scheduled diagnostics can be used to run any of the above tests at user-designated

intervals.

For complete information on the online diagnostic tests and how to run them, refer to the software configuration guide.

3000-W DC Power SupplyC6880-X-3KW-DC

Blank coverC6800-PS-CVR

The power supplies can work together in either of two modes:

• Redundant Mode—Each power supply operates at approximately 50 percent of its capacity, no greater

than 60 percent and no less than 40 percent. If one power supply fails, the other power supply can provide power for the entire system on its own. This is the default and recommended mode for production.

• Combined Mode—Each power supply provides approximately 83 percent of its capacity, providing a

combined capacity of approximately 167 percent. If one power supply fails, the other power supply might not be able to provide power for the entire system. This is not the recommended mode for operation.

Installing Power Supplies

You follow the same steps to install the AC-input and DC-input power supplies, but you must ground them differently.

Before You Begin

The switch chassis must be installed in a cabinet or rack that is secured to the data center.

•

Remove the power supply from its shipping container and remove any packaging.

•

You need the following additional tools and equipment:

•

Nut driver attachment for number 1 Phillips-head screwdriver or ratchet wrench with torque

◦

capability (used only for DC-input power supplies).

Crimping tool.

◦

For the DC-input power supply, you need four power cables sized to reach the DC power source

◦

or power interface unit (PIU).

◦ Grounding wire — Size this wire to meet local and national installation requirements. For U.S.

installations, you must use a 6 AWG copper conductor. For installations outside the U.S., consult your local and national electrical codes. The length of the grounding wire depends on the proximity of the switch to proper grounding facilities.

Installing and Removing Power Supplies

Connecting to the Power Source

You follow the same steps to install the AC-input and DC-input power supplies, but you must ground them differently.

• AC-input power supply—It is automatically grounded when you connect its power cable to the power

supply and the power source.

• DC-input power supply—You do not connect the power supply directly to the earth ground.

You use one power cord for each power supply to connect the power supply to its power source. The number of power sources you use for your power supplies depends on the mode with which you install them:

• Combined mode (no power redundancy)—Connect both power supplies to the same power source.

• Redundancy mode—Connect each power supply to a separate power source.

Before You Begin

Connecting to the Power Source

Caution

Before you connect power supplies to power sources, ensure the following:

The chassis is connected to an earth ground. See Establishing the System Ground, on page 45.

•

You have receptacles for the power sources within reach of the power supply cables.

•

If you are installing more than one DC-input power supply, each must be protected by a dedicated circuit

•

breaker or a fuse that is sized according to the power supply input rating and the local or national electrical code requirements.

The power sources are rated as follows:

•

◦ For North American AC-input installations—20 A with 110 V or 220 V circuits.

◦ For North American DC-input installations—(–48 VDC nominal at 37 A in North America

(operating range: –40.5 to –56 VDC).

◦ For international installations—Size the circuits by local and national standards.

The power supply is already inserted into the chassis.

•

Ensure that the power source is OFF. As an added precaution, place the appropriate safety flag and lockout devices at the source power circuit breaker, or place a piece of adhesive tape over the circuit breaker handle to prevent accidental power restoration while you are working on the circuit.

Warning

Before performing any of the following procedures, ensure that power is removed from the DC circuit. Statement 1003

Installing and Removing Power Supplies

Step 1 Step 2 Step 3

Ensure that the power supply switch located on the front of the power supply is set at standby (labeled as 0).

Plug the power cable into the power supply. Pull down the retention clip over the plug on the power cable.

Plug the other end of the power cable into an power source supplied by the data center.

If you are using the redundant mode, connect each power supply to a separate power source.Note

Step 4 Step 5

Turn the power switch from standby to on (from 0 to 1 as labeled on the power switch).

Verify that the power supply is receiving power and outputting DC power by checking that the INPUT and OUTPUT power supply LEDs are on and the FAULT LED is not on or flashing. For an explanation of all the power supply LEDs and the conditions that they indicate, see AC-Input Power Supply LEDs.

When you first activate the power supply, you can verify the functionality of the LEDs by checking

Tip

that each LED turns on for a couple of seconds. If the Fault LED is flashing red, turn the power switch to standby (labeled as 0), check the AC power connections on the power supply and the AC power source, and then turn the power switch back on (labeled as 1). The Input and Output LEDs for the connected power supplies should be green and the Fault LED should be off.

Connecting to a DC Power Source

To connect the DC power supply directly to one or two DC power sources, follow these steps:

Warning

Before performing any of the following procedures, ensure that power is removed from the DC circuit.Statement 1003

Warning

Hazardous voltage or energy may be present on DC power terminals. Always replace cover when terminals are not in service. Be sure uninsulated conductors are not accessible when cover is in place. Statement

1075.

Procedure

Step 1 Step 2

Ensure that the power supply switch located on the front of the power supply is set at standby (labeled as 0).

Turn off the power at the circuit breakers for the portions of the DC grid power that you are connecting to and verify that all of the LEDs on the power supplies are off.

Installing and Removing Power Supplies

Removing Power Supplies

Step 3

Step 4

Step 5

Step 6

Size the power cables to the distance between the power supply and the DC power grid. If you need to cut the cable, cut it at the end that connects to the DC power grid, remove 0.75 inch (19 mm) of insulation from the cut ends, and attach them to the DC power system. Be sure to connect the negative cables to negative lines and positive cables to positive lines.

Note

For all your power connections, if you are using cables with two different colors, use one color cable for all positive circuits and the other color for all negative circuits.

Remove the three screws that hold down the safety cover for the terminal box on the front of the DC power supply and remove the cover.

Note

The terminal box has four slots for four power terminals (ordered as negative [-], positive [+], positive [+], and negative [-]). Each terminal has two nuts that you use to fasten a power cable to the terminal.

Install four cables (two positive and two negative cables) in the four terminal slots as follows:

Unscrew the two nuts in each of the four terminal slots.

Attach and crimp each lug to the end of each power cable.

Attach each cable lug to the two terminal posts in each slot, fasten with two nuts, and tighten to 40 in-lb

(4.5 N·m).

Note

For all your power connections, if you are using cables with two different colors, use one color cable for all positive circuits and the other color for all negative circuits.

Replace the safety cover on the terminal box and fasten with three screws.

Install the four cables from the DC power supply to an DC power sources as follows:

If the unconnected end of each power cable is not stripped of its insulation for the last 0.75 inches (19

mm), use wire strippers to remove that amount of insulation.

Attach the negative cables to the negative terminals of a DC power source, and attach the positive cables

to the positive terminals of the same power source.

Note

If you are using combined power mode or power supply redundancy mode, connect all the power supplies in the chassis to the same power source. If you are using input source redundancy mode or full redundancy mode, connect half the power supplies to one DC power source and the other half of the power supplies to another DC power source.

Step 7

For the powered down circuits connected to the power supplies, turn on the power at the circuit breaker. The Input 1 (IN1) and Input 2 (IN2) LEDs turn on each connected power supply.

Step 8

Turn the power switch on the connected DC power supplies from standby to on (from 0 to 1 as labelled on the power switch for each power supply). The LEDs should flash and then the Output LED should turn on in addition to the Input LEDs. If the FAULT LED is on or flashing, call Cisco TAC for assistance.

Removing Power Supplies

Procedure

Step 1

Turn off the power to the power supply that you are removing, as follows:

a) Ensure that the power switch on the front of the power supply is set to standby (labeled as 0).

Modular Port Card Installation

Use only supported modular port cards and SFP or SFP+ modules.

Modular Port Card Installation

Note

The switch can operate without a port card, but a blank port card module (with no ports or SFP slots) is available and must be installed when the port card module is not installed.

When installing the port cards, observe these precautions:Caution

Do not remove the dust plugs from the fiber-optic SFP or SFP+ modules or the rubber caps from

•

the fiber-optic cable until you connect the cable. The plugs and caps protect the module ports and cables from contamination and ambient light.

To prevent ESD damage, follow your normal board and component handling procedures when

•

connecting cables to the switch and other devices.

Installing a Modular Port Card

Procedure

Step 1 Step 2

Attach an ESD-preventive wrist strap to your wrist and to an earth ground surface.

Loosen the screw counter-clockwise on the blank module, and pull out the blank module from the chassis.

Class 1 laser product. Statement 1008Warning

Observe these precautions:

Do not remove the dust plugs from the SFP or SFP+ transceiver modules or the rubber caps from the

•

fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the module ports and cables from contamination and ambient light.

Removing and installing an SFP or SFP+ transceiver module can shorten its useful life. Do not remove

•

and insert any SFP or SFP+ transceiver module more often than is necessary.

Caution

Step 1 Step 2

Step 3

Step 4 Step 5

To prevent ESD damage, follow your normal board and component handling procedures when connecting cables to the switch and other devices.

Procedure

Attach an ESD-preventive wrist strap to your wrist and to an earth ground surface.

Find the send (Tx) and receive (Rx) markings that identify the top of the SFP or SFP+ module. On some SFP transceiver modules, the send and receive (Tx and Rx) markings might be represented by arrows that show the direction of the connection.

If the SFP or SFP+ transceiver module has a bale-clasp latch, move it to the open, unlocked position.

Figure 30: Installing an SFP Module

Align the module in front of the slot opening, and push until you feel the connector snap into place.

If the module has a bale-clasp latch, close it to lock the SFP transceiver module in place.

Note

If you are inserting the SFP transceiver module in the lower ports, you need to invert the module as shown above.
