Preventing ESD Damage


Warning

This equipment needs to be grounded. Use a green and yellow 6 AWG ground wire to connect the host to earth ground during normal use. Statement 383

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD can occur when electronic printed circuit cards are improperly handled and can cause complete or intermittent failures. When removing and replacing modules, always follow ESD prevention procedures:

  • Ensure that the router chassis is electrically connected to earth ground.
  • Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. To channel unwanted ESD voltages safely to ground, connect the clip to an unpainted surface of the chassis frame. To guard against ESD damage and shocks, the wrist strap and cord must operate effectively.
  • If no wrist strap is available, ground yourself by touching a metal part of the chassis.
  • When installing a component, use any available ejector levers or captive installation screws 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 available ejector levers or captive installation screws, if any, to release the bus connectors from the backplane or midplane.
  • Handle components by their handles or edges only; do not touch the printed circuit boards or connectors.
  • 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.

Note
For the safety of your equipment, periodically check the resistance value of the antistatic wrist strap. It should be between 1 and 10 Mohm.

Site Selection Guidelines

The Cisco ASR 903 Router as a satellite shelf requires specific environmental operating conditions. Temperature, humidity, altitude, and vibration can affect the performance and reliability of the router. The following sections provide specific information to help you plan for the proper operating environment.

The Cisco ASR 903 Router as a satellite shelf is designed to meet the industry EMC, safety, and environmental standards described in the Regulatory, Safety, and Compliance Information for the Cisco ASR 903 Router.

Environmental Requirements

Environmental monitoring in the Cisco ASR 903 Router as a satellite shelf protects the system and components from damage caused by excessive voltage and temperature conditions. To ensure normal operation and avoid unnecessary maintenance, plan and prepare your site configuration before installation. After installation, make sure that the site maintains the environmental characteristics described in the Cisco ASR 903 System Specifications section.

Physical Characteristics

Be familiar with the physical characteristics of the Cisco ASR 903 Router as a satellite shelf to assist you in placing the system in the proper location. For more information, see the Cisco ASR 903 System Specifications section.

AirFlow Guidelines

Cool air is circulated through the Cisco ASR 903 Router as a satellite shelf by a fan tray located along the right side of the router. Airflow is side to side, right to left, as shown in this figure.

Figure 1. Cisco ASR 903 as a Satellite Shelf Chassis Airflow

The fan trays maintain acceptable operating temperatures for the internal components by drawing in cool air through the vents, and circulating the air through the chassis.

The following guidelines will help you plan your equipment rack configuration:

  • To ensure adequate airflow through the equipment rack, we recommend that you maintain a clearance of at least 80 mm on each side of the rack at all times.
  • If airflow through the equipment rack and the routers that occupy it is blocked or restricted, or if the ambient air being drawn into the rack is too warm, an overtemperature condition can occur within the rack and the routers that occupy it.
  • The site should also be as dust-free as possible. Dust tends to clog the router fans, reducing the flow of cooling air through the equipment rack and the routers that occupy it, thus increasing the risk of an overtemperature condition.
  • Enclosed racks must have adequate ventilation. Ensure that the rack is not congested, because each router generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air. Heat that is generated by the equipment near the bottom of the rack can be drawn upward into the intake ports of the equipment above.
  • When mounting a chassis in an open rack, ensure that the rack frame does not block the side intakes and the exhaust fans.
  • When rack-installed equipment fails, especially equipment in an enclosed rack, try operating the equipment by itself, if possible. Power off all other equipment in the rack (and in adjacent racks) to give the router maximum cooling air and clean power.
  • Avoid locating the Cisco ASR 903 Router as a satellite shelf in a location in which the chassis air intake vents may draw in the exhaust air from adjacent equipment. Consider how the airflows through the router; the airflow direction is side to side, with ambient air drawn in from the vents located on the front right of the chassis.

Airflow Guidelines for Enclosed Rack Installation

To install a Cisco ASR 903 Router as a satellite shelf in a 4-post enclosed cabinet, the front and rear doors of the cabinet must be removed or be perforated with a minimum of 65 percent open area (70 percent for 800-mm racks).

If you are mounting the chassis in a 4-post enclosed cabinet, ensure that you have a minimum of 6 inches (15.24 cm) of clearance on each side of the chassis.

Floor Loading Considerations

Ensure that the floor under the rack supporting the Cisco ASR 903 Router as a satellite shelf is capable of supporting the combined weight of the rack and all the other installed equipment.

To assess the weight of a fully configured Cisco ASR 903 Router as a satellite shelf, see the Cisco ASR 903 System Specifications section.

For additional information about floor loading requirements, consult GR-63-CORE, Network Equipment Building System (NEBS) Requirements: Physical Protection .

Site Power Guidelines

The Cisco ASR 903 Router as a satellite shelf has specific power and electrical wiring requirements. Adhering to these requirements ensures reliable operation of the system. Follow these precautions and recommendations when planning your site power for the Cisco ASR 903 Router as a satellite shelf:

  • The redundant power option provides a second, identical power supply to ensure that power to the chassis continues uninterrupted if one power supply fails or input power on one line fails.
  • In systems configured with the redundant power option, connect each of the two 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 a loss of input power, be sure that the total maximum load on each circuit supplying the power supplies is within the current ratings of the wiring and the breakers.
  • Check the power at your site before installation and periodically after installation to ensure that you are receiving clean power. Install a power conditioner if necessary.
  • Provide proper grounding to avoid personal injury and damage to the equipment due to lightning striking power lines or due to power surges. The chassis ground must be attached to a central office or other interior ground system.

For more information about the Cisco ASR 903 Router power supply, see theCisco ASR 903 Router Hardware Installation Guide.

Site Cabling Guidelines

This section contains guidelines for wiring and cabling at your site. When preparing your site for network connections to the Cisco ASR 903 Router as a satellite shelf, consider the type of cable required for each component, and the cable limitations. Consider the distance limitations for signaling, electromagnetic interference (EMI), and connector compatibility. Possible cable types are fiber, thick or thin coaxial, foil twisted-pair, or unshielded twisted-pair cabling.

Also consider any additional interface equipment you need, such as transceivers, hubs, switches, modems, channel service units (CSU), or data service units (DSU).

Before you begin, read these important notes about cabling:

  • The T1/E1 interface module for the Cisco ASR 903 Router uses a high-density connector that requires the use of a T1/E1 interface cable and a customer-provided patch panel. For more information, see the Cisco ASR 903 Router Hardware Installation Guide . Note that the Cisco ASR 903 Router as a satellite shelf does not use the T1/E1 interface module. The Cisco ASR 903 Router as a satellite shelf supports only ethernet ports.
  • Shielded cables must be used to connect to the DB-25 alarm connector on the fan tray in order to comply with FCC/EN55022/CISPR22 Class A emissions requirements. For information about the fan tray alarm port, see the Cisco ASR 903 Router Hardware Installation Guide.

Before you install the Cisco ASR 903 Router as a satellite shelf, have all the additional external equipment and cables on hand. For information about ordering, contact a Cisco customer service representative.

The extent of your network and the distances between the network interface connections depend in part on the following factors:

  • Signal type
  • Signal speed
  • Transmission medium

The distance and rate limits referenced in the following sections are the IEEE-recommended maximum speeds and distances for signaling purposes. Use this information as a guideline in planning your network connections >prior to installing the Cisco ASR 903 Router as a satellite shelf.

If 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.

Asynchronous Terminal Connections

The RSP provides a console port to connect a terminal or computer for local console access. The port has an RJ-45 connector and supports RS-232 asynchronous data with distance recommendations specified in the IEEE RS-232 standard.

Interference Considerations

When wires are run for any significant distance, there is a risk that stray signals will be induced on the wires as interference. If interference signals are strong, they can cause data errors or damage to the equipment.

The following sections describe sources of interference and how to minimize its effects on the Cisco ASR 903 system.

Electromagnetic Interference

All equipment powered by AC current can propagate electrical energy that can cause EMI and possibly affect the operation of other equipment. The typical sources of EMI are equipment power cords and power service cables from electric utility companies.

Strong EMI can destroy the signal drivers and receivers in the Cisco ASR 903 and even create an electrical hazard by causing power surges through the power lines into installed equipment. These problems are rare but could be catastrophic.

To resolve these problems, you need specialized knowledge and equipment that could consume substantial time and money. However, you can ensure that you have a properly grounded and shielded electrical environment, paying special attention to the need for electrical surge suppression.

For information about the electrode magnetic compliance standards supported on the Cisco ASR 903 Router as a satellite shelf, see Regulatory Compliance and Safety Information for the Cisco ASR 903 Router.

Radio Frequency Interference

When electromagnetic fields act over a long distance, radio frequency interference (RFI) may be propagated. Building wiring can often act as an antenna, receiving the RFI signals and creating more EMI on the wiring.

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.

Lightning and AC Power Fault Interference

If signal wires exceed the recommended cabling distances, or if signal wires pass between buildings, you should consider the effect that a lightning strike in your vicinity might have on the Cisco ASR 903 Router as a satellite shelf.

The electromagnetic pulse (EMP) generated by lightning or other high-energy phenomena can couple enough energy into unshielded conductors to damage or destroy electronic equipment. If you have previously experienced such problems, you should consult with RFI and EMI experts to ensure that you have adequate electrical surge suppression and shielding of signal cables in your Cisco ASR 903 Router as a satellite shelf operating environment.

Rack-Mounting Guidelines

These sections provide guidelines for rack-mounting the Cisco ASR 903 Router as a satellite shelf:

Rack-Mounting Precautions

These rack-mount guidelines are provided to ensure your safety:

  • Do not move large racks by yourself. Due to the height and weight of a rack, a minimum of two people are required to accomplish this task.
  • Ensure that the rack is level and stable before extending a component from the rack.
  • Ensure that proper airflow is provided to the components in the rack.
  • Do not step on or stand on any component or system when servicing other systems or components in a rack.
  • When mounting the Cisco ASR 903 Router as a satellite shelf in a partially filled rack, load the rack from the bottom to the top, with the heaviest component at the bottom of the rack.
  • If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.

Rack Selection Guidelines

The Cisco ASR 903 Router as a satellite shelf can be mounted in most two-post or four-post, 19-inch equipment racks that comply with the Electronic Industries Association (EIA) standard for equipment racks (EIA-310-D 19-inch). The rack must have at least two posts with mounting flanges to mount the chassis.


Caution

When mounting a chassis in any type of rack equipment, ensure that the inlet air to the chassis does not exceed 65 degrees C.

The distance between the center lines of the mounting holes on the two mounting posts must be 18.31 inches ± 0.06 inch (46.50 cm ± 0.15 cm). The rack-mounting hardware included with the chassis is suitable for most 19-inch equipment racks.

Consider installing the Cisco ASR 903 Router as a satellite shelf in a rack with the following features:

  • Network Equipment Building System (NEBS) compliant, 19-inch (48.3-cm) wide rack.
  • EIA or European Telecommunications Standards Institute (ETSI) hole patterns in the mounting rails. The required mounting hardware is shipped with the Cisco ASR 903. If the rack that you plan to install the system in has metric-threaded rails, you must provide your own metric-mounting hardware.
  • Perforated top and open bottom for ventilation to prevent overheating.
  • Leveling feet for stability.

Note
The Cisco ASR 903 Router as a satellite shelf should not be installed in an enclosed rack because the chassis requires an unobstructed flow of cooling air to maintain acceptable operating temperatures for its internal components. Installing the router in any type of enclosed rack—even with the side doors removed —could disrupt the airflow, trap heat next to the chassis, and cause an overtemperature condition inside the router. If you use an enclosed rack, ensure that there are air vents on all sides of the rack and there is proper ventilation.

Equipment Rack Guidelines

The placement of the rack can affect personnel safety, system maintenance, and the system’s ability to operate within the environmental characteristics described in the Cisco ASR 903 System Specifications section. Choose a proper location for the Cisco ASR 903 Router as a satellite shelf by following these guidelines.

Locating for Safety

If the Cisco ASR 903 Router as a satellite shelf is the heaviest or the only piece of equipment in the rack, consider installing it at or near the bottom to ensure that the rack’s center of gravity is as low as possible.

For additional information about the proper placement of electronic equipment, consult the document GR-63-CORE, Network Equipment Building System (NEBS) Requirements: Physical Protection.

Locating for Easy Maintenance

Keep at least 3 feet of clear space at the front and back of the rack. This space ensures that you can remove the Cisco ASR 903 Router as a satellite shelf components and perform routine maintenance and upgrades easily.

Avoid installing the Cisco ASR 903 Router as a satellite shelf in a congested rack and consider how routing of cables from other pieces of equipment in the same rack could affect access to the router cards.

The sides of the chassis must remain unobstructed to ensure adequate airflow and prevent overheating inside the chassis.

Allow the following clearances for normal system maintenance:

  • At the top of the chassis—At least 3 inches (7.6 cm)
  • Sides of the chassis—3 to 4 ft (91.44 cm to 121.92 cm)

To avoid problems during installation and ongoing operations, follow these general precautions when you plan equipment locations and connections:

  • Use the show environment all command regularly to check the internal system status. The environmental monitor continually checks the interior chassis environment; it provides warnings about high temperature and creates reports on other potentially dangerous occurrences. If warning messages are displayed, take immediate action to identify the cause, and correct the problem.
  • Keep the Cisco ASR 903 Router as a satellite shelf off the floor and out of areas that collect dust.
  • Follow ESD-prevention procedures to avoid damage to equipment. Damage from static discharge can cause immediate or intermittent equipment failure.
Locating for Proper Airflow

Ensure that the Cisco ASR 903 Router as a satellite shelf has enough airflow to keep the system operating within the environmental characteristics and the air temperature is sufficient to compensate for the heat dissipated by the system. For more information, see the AirFlow Guidelines section.

Note
We recommend that you have at least two people available to help with the installation and ensure safe lifting.

Chassis-Lifting Guidelines

The chassis is not intended to be moved frequently. Before you install the system, ensure that your site is properly prepared so that you can avoid having to move the chassis later to accommodate power sources and network connections.

Two or more people are required to lift the chassis. Each time you lift the chassis or any heavy object, follow these guidelines:

  • Never attempt to lift the chassis by yourself. Because of the size and weight of the chassis, use at least two people to safely lift and move it without causing injury to yourself or damaging the equipment.
  • Ensure that your footing is solid, and balance the weight of the chassis between your feet.
  • Lift the chassis slowly; never move suddenly or twist your body as you lift.
  • Keep your back straight and lift with your legs, not your back. If you must bend down to lift the chassis, bend at the knees, not at the waist, to reduce the strain on your back muscles.
  • Do not remove installed components from the chassis.
  • Always disconnect all external cables before lifting or moving the chassis.

Warning

To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the handles on modules (such as power supplies, fans, or cards); these types of handles are not designed to support the weight of the unit. Statement 1032

Installing and Removing an RSP Module

Follow these steps on handling an RSP module in the Cisco ASR 903 Router as a satellite shelf:

Installing an RSP Module

To install an RSP module in the router chassis, perform the following steps:

SUMMARY STEPS

  1. Choose a slot for the module. Make sure that there is enough clearance to accommodate any equipment that will be connected to the ports on the module. If a blank module filler plate is installed in the slot in which you plan to install the module, remove the plate by removing its two Phillips pan-head screws.
  2. Fully open both the ejector levers on the new module, as shown in this figure.
  3. Position the module in the slot. Make sure that you align the sides of the module with the guides on each side of the slot, as shown in this figure.
  4. Carefully slide the module into the slot until the EMI gasket on the module makes contact with the module in the adjacent slot and both the ejector levers have closed to approximately 45 degrees with respect to the module faceplate.
  5. While pressing down, simultaneously close both the ejector levers to fully seat the module in the backplane connector. The ejector levers are fully closed when they are flush with the module faceplate.
  6. Tighten the two captive installation screws on the module. The recommended maximum torque is 5.5 lbf/sq in.
  7. Verify that the captive installation screws are tightened on all of the modules installed in the chassis. This step ensures that the EMI gaskets on all the modules are fully compressed in order to maximize the opening space for the new or replacement module.

DETAILED STEPS

Step 1

Choose a slot for the module. Make sure that there is enough clearance to accommodate any equipment that will be connected to the ports on the module. If a blank module filler plate is installed in the slot in which you plan to install the module, remove the plate by removing its two Phillips pan-head screws.

Step 2

Fully open both the ejector levers on the new module, as shown in this figure.

Caution 

To prevent ESD damage, handle modules by carrier edges only.

Step 3

Position the module in the slot. Make sure that you align the sides of the module with the guides on each side of the slot, as shown in this figure.

Figure 16. Cisco ASR 903 RSP Installation
Step 4

Carefully slide the module into the slot until the EMI gasket on the module makes contact with the module in the adjacent slot and both the ejector levers have closed to approximately 45 degrees with respect to the module faceplate.

Caution 

If the top slot already has an RSP module installed, and you install a second RSP module in the slot below it, be careful during insertion not to damage the EMI gasket of the bottom RSP module against the ejector levers of the top RSP.

Step 5

While pressing down, simultaneously close both the ejector levers to fully seat the module in the backplane connector. The ejector levers are fully closed when they are flush with the module faceplate.

Step 6

Tighten the two captive installation screws on the module. The recommended maximum torque is 5.5 lbf/sq in.

Note 
Make sure that the ejector levers are fully closed before tightening the captive installation screws.
Step 7

Verify that the captive installation screws are tightened on all of the modules installed in the chassis. This step ensures that the EMI gaskets on all the modules are fully compressed in order to maximize the opening space for the new or replacement module.

If the captive installation screws are loose, the EMI gaskets on the installed modules will push adjacent modules toward the open slot, which reduces the size of the opening and makes it difficult to install the new module.

Blank module filler plates (Cisco part number A900-RSPA-BLANK) should be installed in any empty chassis slots to keep dust out of the chassis and to maintain consistent airflow through the chassis.

Removing an RSP Module

Before you remove an RSP from the router, you should save the current configuration using the write {host file | network | terminal} command. This saves you time when bringing the module back online.

If the module is running Cisco IOS software, save the current running configuration by entering the copy running-config startup-config command.


Warning

Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034


Warning

Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051

To remove an RSP module, perform the following steps:

SUMMARY STEPS

  1. Disconnect any cables attached to the ports on the module.
  2. Verify that the captive installation screws on all the modules in the chassis are tight. This step ensures that the space created by the removed module is maintained.
  3. Loosen the two captive installation screws on the module that you plan to remove from the chassis.
  4. Place your thumbs on the ejector levers (see the figure Cisco ASR 903 RSP Installation) and simultaneously rotate the ejector levers outward to unseat the module from the backplane connector.
  5. Grasp the front edge of the module and slide the module straight out of the slot. If the chassis has horizontal slots, place your hand under the module to support its weight as you slide it out from the slot. Do not touch the module circuitry.
  6. Place the module on an antistatic mat or antistatic foam, or immediately reinstall the module in another slot.
  7. Install blank module filler plates (Cisco part number A900-RSPA-BLANK) in empty slots, if any.

DETAILED STEPS

Disconnect any cables attached to the ports on the module.

Step 2

Verify that the captive installation screws on all the modules in the chassis are tight. This step ensures that the space created by the removed module is maintained.

Note 
If the captive installation screws are loose, the EMI gaskets on the installed modules will push the modules toward the open slot, which in turn reduces the size of the opening and makes it difficult to remove the module.
Step 3

Loosen the two captive installation screws on the module that you plan to remove from the chassis.

Step 4

Place your thumbs on the ejector levers (see the figure Cisco ASR 903 RSP Installation) and simultaneously rotate the ejector levers outward to unseat the module from the backplane connector.

Step 5

Grasp the front edge of the module and slide the module straight out of the slot. If the chassis has horizontal slots, place your hand under the module to support its weight as you slide it out from the slot. Do not touch the module circuitry.

Caution

  • DC power—19.2VDC to –72VDC

The DC power supply uses three-position terminal block-style connector with positive latching/securing and labeled connections for +24/48V, GRD, –24/48V. The terminal block connector is of suitable size to carry the appropriate AWG wire size to handle the input current of the power supply. No ON/OFF switch is provided.

  • AC power—85 VAC to 264 VAC

The AC power supply has an IEC 320-type power receptacle and a 15-A service connector. You can use standard right angle power cords with the AC power supply. The power supply includes a power cord retainer. No ON/OFF switch is provided.

Each power supply provides a single primary input power connection. You can install dual power supplies for redundancy.


Warning

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


Note
Products that have an AC power connection are required to have an external surge protective device (SPD) provided as part of the building installation to comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety.

Caution

Do not use interface-module and power-supply ejector handles to lift the chassis; using the handles to lift the chassis can deform or damage the handles.

These sections describe the Cisco ASR 903 Router satellite shelf power supplies:

Preventing Power Loss

Use the following guidelines to prevent power loss to the router.

  • To prevent loss of input power, ensure that the total maximum load on each circuit supplying the power supplies is within the current ratings of the wiring and breakers.
  • In some systems, you can use an UPS to protect against power failures at your site. Avoid UPS types that use ferroresonant technology. These UPS types can become unstable with systems like the Cisco ASR 903 Router as a satellite shelf, which can have substantial current draw fluctuations due to bursty data traffic patterns.

Use the information in the Cisco ASR 9000v Satellite Shelf with a DC Power Module section to estimate the power requirements and heat dissipation of a Cisco ASR 903 Router as a satellite shelf based on a given configuration of the router. Determining power requirements is useful for planning the power distribution system needed to support the router.

Connecting the Fan Tray Alarm Port

The fan tray includes an alarm port that maps to 4 dry contact alarm inputs.

The pins on the alarm port are passive signals and can be configured as Normally Open (an alarm generated when current is interrupted) or Normally Closed (an alarm is generated when a circuit is established) alarms. You can configure each alarm input as critical, major, or minor. An alarm triggers alarm LEDs and alarm messages. The relay contacts can be controlled through any appropriate third-party relay controller. The open/close configuration is an option controlled in Cisco IOS software.


Warning

The intra-building port(s) of the equipment or subassembly must not be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE) 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 OSP wiring. Statement 7005

Only Pins 1, 2, 4, 6, and 8 are available for customer use. The remaining pins are for Cisco manufacturing test, and should not be connected. Use a shielded cable for connection to this port for EMC protection. Table B-21 on page B-28 summarizes the pinouts on the alarm port.

SUMMARY STEPS

  1. Attach an RJ-45 cable to the alarm port.
  2. Attach the other end of the RJ-45 cable to the relay controller.

DETAILED STEPS

Step 1
