• Ensure that the installation of the router is in compliance with national and local electrical codes: in the United States, National Fire Protection Association (NFPA) 70, United States National Electrical Code; in Canada, Canadian Electrical Code, part I, CSA C22.1; in other countries, International Electrotechnical Commission (IEC) 364, part 1 through part 7.

The Cisco ASR 9000 Series Routers are designed to meet the regulatory compliance and safety approval requirements. For detailed safety information, see the Regulatory Compliance and Safety Information - Cisco ASR 9000 Series Aggregation Router.

Warning

IMPORTANT SAFETY INSTRUCTIONS Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. Read the installation instructions before using, installing, or connecting the system to the power source. Use the statement number at the beginning of each warning statement to locate its translation in the translated safety warnings for this device. SAVE THESE INSTRUCTIONS

Single-mode Cisco ASR 9000 Series line cards are equipped with lasers. The lasers emit invisible radiation. Do not stare into open line card ports.

The Cisco ASR 9000 Series Routers can be configured for a DC power source. Do not touch terminals while they are live. Observe the following warning to prevent injury.

Warning

Hazardous voltage or energy may be present on power terminals. To reduce the risk of electric shock, make sure the power terminal cover is in place when the power terminal is not being serviced. Be sure uninsulated conductors are not accessible when the cover is in place.

Many router components can be damaged by static electricity. Not exercising the proper electrostatic discharge (ESD) precautions can result in intermittent or complete component failures. To minimize the potential for ESD damage, always use an ESD-preventive antistatic wrist strap (or ankle strap) and ensure that it makes good skin contact.

Note	Check the resistance value of the ESD-preventive strap periodically. The measurement should be between 1 and 10 megohms.

Before you perform any of the procedures in this guide, attach an ESD-preventive strap to your wrist and connect the leash to the chassis as shown in the figures below.

Fully configured Cisco ASR 9000 Series Routers can weigh as much as 1038 pounds (470.28 kg), and an empty chassis weighs up to 300 pounds (136 kg). These systems are not intended to be moved frequently. Before you install the router, ensure that your site is properly prepared to prevent moving the router later to accommodate power sources and network connections.

To move the pallet assembly, use a pallet jack or forklift. Do not top lift.

To remove the unpacked chassis from the pallet base and to insert the chassis into the rack, we strongly recommend that you use a forklift or scissor-lift, supporting the chassis by the base only.

If you are moving a smaller chassis, use the following lifting guidelines to avoid injury to yourself or damage to the equipment:

• Do not lift equipment alone; have another person help you to lift heavy equipment.

• Ensure that your footing is solid; balance the weight of the object between your feet.

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

• Keep your back straight and lift with your legs, not your back. When bending down to lift equipment, bend at the knees (not at the waist), to reduce the strain on your lower back muscles.

Warning

To prevent injury and equipment damage, never attempt to lift or tilt the router chassis using the handles on the fan tray or on line cards. These handles do not support the weight of the chassis.

Note	Refer to the Rack-Mounting Specifications section in the Cisco ASR 9000 Series Aggregation Services Router Overview and Reference Guide for rack mounting specifications and chassis dimensions.

To help maintain trouble-free operation, adhere to the following precautions and guidelines when planning your rack installation:

• Install the system in a restrictive access location with means for a permanent ground.

• Ensure the site of the rack includes provisions for source AC or DC power, grounding, and network interface cables.

• Allow sufficient space to work around the rack during the installation. You need:

  • At least 3 ft (91.44 cm) adjacent to the rack to move, align, and insert the chassis.

  • At least 2 ft (60.96 cm) in front of the power tray to insert power modules.

• Maintain at least 24 inches (61 cm) of clearance in front of and behind the chassis for maintenance after installation.

  Note

  For the Cisco ASR 9910 Router, maintain at least 30 inches (76.2 cm) of clearance behind the chassis for maintenance after installation (for removal and installation of the rear-mounted fan tray). For the Cisco ASR 9904 Router, maintain at least 26 inches (66.0 cm) of clearance behind the chassis for maintenance after installation (for removal and installation of the rear-mounted fan tray and air filter). For the Cisco ASR 9006 Router, maintain at least 25 inches (63.5 cm) of clearance behind the chassis for maintenance after installation (for removal and installation of the rear-mounted air filter).

• To mount the router between two posts or rails, the usable aperture (the width between the inner edges of the two mounting flanges) must be at least:

  • 17.50 inches (44.45 cm) for the Cisco ASR 9010 Router.

  • 17.75 inches (45.09 cm) for the Cisco ASR 9006 Router, Cisco ASR 9904 Router, and Cisco ASR 9906 Router.

  • 17.60 inches (44.70 cm) for the Cisco ASR 9910 Router.

• To mount the router in a 4-post rack, the usable aperture (the width between the inner edges of the two mounting flanges) must be at least 17.75 inches (45.09 cm) for the Cisco ASR 9922 Router or Cisco ASR 9912 Router.

• When fully populated with cards, the router can weigh up to 1038 pounds (470.28 kg). To maintain equipment rack stability and to ensure your safety, the rack is provided with stabilizing devices. Make sure you install the stabilizers before installing the router.

• If you use a telco-style rack, the weight of the chassis is cantilevered off of the two rack posts. Make sure that:

  • Weight of the router does not make the frame unstable.

  • Frame is bolted to the floor and is secured to the building structure using either wall brackets or overhead brackets.

• When mounting the router in a telco-style rack or 4-post rack, be sure to use all of the screws provided to secure the chassis to the rack posts.

• Install the cable-management brackets included with the router to keep cables organized. Be sure to:

  • Use appropriate strain-relief methods to protect cables and equipment connections.

  • Make sure that cables from other equipment installed in the rack do not restrict access to the card cages.

• To avoid noise interference in network interface cables, do not route them directly across or along power cables.

When planning the location of the router, consider distance limitations for signaling, electromagnetic interference (EMI), and connector compatibility. If the wiring is run for any significant distance in an electromagnetic field, interference can occur between the field and the signals on the wires. Poor wiring can cause:

• Radio interference emanating from the wires.
• Strong EMI, especially when caused by lightning or radio transmitters. EMI can destroy the signal drivers and receivers in the router, and can even create an electrical hazard by conducting power surges through lines and into equipment.

Note	To predict and remedy strong EMI, you may need to consult with experts in radio frequency interference (RFI).

Site wiring is unlikely to emit radio interference if you use twisted-pair cable with a good distribution of grounding conductors. Use a high-quality twisted-pair cable with one ground conductor for each data signal, when applicable.

Give special consideration to the effect of a lightning strike in your vicinity, especially if the wiring exceeds the recommended distances, or if it passes between buildings. The electromagnetic pulse (EMP) caused by lightning or other high-energy phenomena can easily induce enough energy into unshielded conductors to destroy electronic devices. If you have experienced EMP problems in the past, you may want to consult experts in electrical surge suppression and shielding.

Most data centers cannot resolve infrequent but potentially catastrophic problems without pulse meters and other special equipment. In addition, these problems can take a great deal of time to identify and resolve. We recommend that you take the necessary precautions to avoid these problems by providing a properly grounded and shielded environment, with special attention to issues of electrical surge suppression.

Refer to the Cooling System Functional Description section in the Cisco ASR 9000 Series Aggregation Services Router Overview and Reference Guide for information on fan tray and chassis air flow information.

When selecting a site to install the router, observe the following guidelines:

• Dust-free area—The site should be as dust-free as possible. Dusty environments can clog the air filter or power supply intake vents, reducing the cooling air flow through the router. Clogged filters and vents can cause an overtemperature condition in the router.

• Unrestricted air-flow—Allow sufficient air-flow by maintaining a minimum of 6 in (15.24 cm) of clearance at both the inlet and exhaust openings on the chassis and the power modules. If the air flow is blocked or restricted, or if the inlet air is too warm, an overtemperature condition can occur within the router. Under extreme conditions, the environmental monitoring system powers off the router to protect the components.

The Cisco ASR 9010 Router, Cisco ASR 9006 Router, Cisco ASR 9904 Router, Cisco ASR 9906 Router, and Cisco ASR 9910 Router can be installed in most 2-post, 4-post, or telco-style 19-inch equipment racks that comply with the Electronics Industries Association (EIA) standard for equipment racks (EIA-310-D).

Note

The Cisco ASR 9922 Router and Cisco ASR 9912 Router can be mounted only in a 4-post rack. The rack must have at least two posts with mounting flanges to mount the router chassis. 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).

This figure shows an examples of typical 2-post and 4-post telco-type equipment racks.

The operating and nonoperating environmental site requirements are listed in Cisco ASR 9000 Series Routers Environmental Specifications section of Cisco ASR 9000 Series Aggregation Services Router Overview and Reference Guide.

The router normally operates within the ranges listed in the table; however, if a temperature measurement is approaching a minimum or maximum parameter, it indicates a potential problem. Maintain normal operation by anticipating and correcting environmental anomalies before they approach critical values by properly planning and preparing your site before you install the router.

You can configure the router with either an AC input or DC input power subsystem, so the site power source requirements differ depending on the power subsystem in your router. Ensure all power connection wiring conforms to the rules and regulations in the National Electrical Code (NEC) as well as local codes.

Caution

Each Cisco ASR 9000 Series Router is powered by only one type of input: AC or DC. A hybrid (AC+DC) power configuration is not supported.

Caution

Proper grounding is necessary to avoid damage from lightning and power surges. See NEBS Supplemental Unit Bonding and Grounding Guidelines for grounding requirements.

The router is sensitive to variations in voltage supplied by the power sources. Overvoltage, undervoltage, and transients (or spikes) can erase data from memory or cause components to fail. To protect against these types of problems, ensure that there is an earth-ground connection for the router. You can connect the grounding pad on the router either directly to the earth-ground connection or to a fully bonded and grounded rack.

When you properly install the chassis in a grounded rack, the router is grounded because it has a metal-to-metal connection to the rack. Alternatively, you can ground the chassis by using a customer-supplied grounding cable that meets your local and national installation requirements (we recommend 6-AWG wire for U.S. installations). One end of the grounding cable is connected to the chassis with a grounding receptacle (provided in the router accessory kit) and the other end to the appropriate grounding point at your site.

Although the router chassis requires a safety earth ground connection as part of the power cabling to power modules, you must permanently connect the central office ground system or interior equipment grounding system to one of the three supplemental bonding and grounding connections on the back or side of the router chassis to meet Network Equipment Building System (NEBS) requirements as well as safety compliance requirements. These grounding points are referred to as the NEBS bonding and grounding points.

Note

You automatically ground the chassis with AC power modules when you connect them to AC power sources. However, it is still strongly recommended to provide an additional direct earth-ground connection for the chassis. For DC power supplies, it is mandatory to connect a grounding wire when wiring the power supply to the DC power source.

To ensure a satisfactory supplemental ground connection to the router, use the following parts:

• One grounding lug, which has two holes with 0.625- to 0.75-inch (15.86- to 19.05-mm) spacing between them, and a wire receptacle able to accept a #6 AWG or larger, multistrand copper wire.

• Two 10-32 x 0.25-inch round-head screws and two locking washers (nickel-plated brass is ideal).

Note	The chassis ground wire connectors have a torque value of 30 in-lb.

• One grounding wire. Although we recommend at least #6 AWG multistrand copper wire, the wire diameter and length depend on your router location and site environment.

Note	These parts are not available from Cisco, but they are available from commercial vendors.

Each RSP/RP card has two EIA/TIA-232 (formerly RS232) serial RJ-45 connection ports:

• Console port—RJ-45 interface for connecting a data terminal device to the router, which you need to perform the initial configuration of the router.

• Auxiliary port—RJ-45 interface for connecting a modem.

Note	The console and auxiliary ports are asynchronous serial ports. Ensure that devices connected to these ports are capable of asynchronous transmission.

Each RSP/RP card has two RJ-45 media-dependent interface (MDI) Ethernet management LAN ports: MGT LAN 0 and MGT LAN 1. These ports are used for IEEE 802.3u 100BASE-TX (100 Mbps), or 1000BASE-T (1000 Mbps) Ethernet connections. .

The transmission speed of the management LAN ports is not user-configurable. The transmission speed is set through an autosensing scheme on the RSP/RP; the speed is determined by the network that the Ethernet port is connected to. The combined total input rate of both MGT LAN 0 and MGT LAN 1 is about 12 Mbps.

Management port characteristics are:

• Maximum transmission unit (MTU) is fixed at 1514 and cannot be configured.

• Flow control is disabled and cannot be configured.

• Input unicast packets with an unknown destination address are filtered and dropped.

• Autonegotiation of port speed (100/1000) and duplex (full/half) is supported. Autonegotiation cannot be disabled.

This table lists the signals used on the Management LAN ports.

The RSP/RP card has an alarm connector on its front panel. This 9-pin D-subconnectors (ALARM OUT) connects the router to an external site alarm maintenance system. When a critical, major, or minor alarm is generated, it energizes the alarm relays on the RSP/RP card to activate the external site alarm.

The alarm relay contacts on the RSP/RP card consist of standard common , normally open , and normally closed relay contacts that are wired to the pins on the connectors.

Caution

Only safety extra-low voltage (SELV) circuits can be connected to the alarm connector. Maximum rating for the alarm circuit is 100 mA, 50 V.

Note

To comply with the intrabuilding lightning surge requirements of Telecordia GR-1089-CORE, Issue II, Revision 01, February 1999, you must use a shielded cable when connecting to the external alarm port on the RSP/RP card. The shielded cable is terminated by shielded connectors on both ends, with the cable shield material tied to both connectors.

This table lists the pin-to-signal correspondence between the cable connector pins and the alarm connector relay contacts.

The SYNC 0 and SYNC 1 ports are timing synchronization ports. They can be configured as Building Integrated Timing Supply (BITS) ports or J.211 ports.

Note	Both ports must be configured to be the same mode. It is not possible to use external BITS and J.211 sources at the same time.

When configured as BITS ports, they provide connections for an external synchronization source for establishing precise frequency control at multiple network nodes, if required for your application. The RSP/RP card contains a synchronous equipment timing source (SETS) that can receive a frequency reference from an external BITS timing interface or from a clock signal recovered from any incoming Gigabit Ethernet or 10-Gigabit Ethernet interface. The RSP/RP SETS circuit filters the received timing signal and uses it to drive outgoing Ethernet interfaces.

The BITS input can be T1, E1 or 64K 4/. The BITS output can be T1, E1 or 6.312M 5/.

When configured as J.211 ports, they can be used as Universal Timing Interface (UTI) ports to synchronize timing across multiple routers by connecting to an external timing source.

When lit, these LEDs indicate for BITS:

• Green (LINK)—Connection is alive.

• Amber (FAULT)—A fault has occurred.

When lit, these LEDs indicate for UTI:

• Green (NORMAL)—UTI is operating in normal mode.

• Amber (FAST)—UTI is operating in fast mode.
