To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your network is “down,” or there is a crit ical impact to your business operatio ns. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing networ k is severely degraded, or signi ficant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is li ttle or no effect on you r business operations.

The backplane slots are keyed so that the processor modules can be installed only in the slots designated for them. Keys on the backplane fit into two key guides on each module. Although the RSP uses unique keys, all fo ur int erface processor slots use the same key, so you can install an interface processor in any interface processor slot, but not in the RSP slot.

Interface processors connected to one CyB u s are unaffected by the traffic generated by the in ter f ace processors connected to the other CyBus. The two CyBuses are independent of one another.

The backplane slots are keyed so that the processor modules can be installed only in the slots designated for them. Keys on the backplane fit into two key guides on each module. Although the RSP uses unique keys, all eleven interface processor slots use the same key, so you can install an interface processor in any interface processor slot, but not in the RSP slot.

Cisco 7576 Overview

The Cisco 7576 router s upports multipr otocol, multime dia r outing a nd bridging with a wide variety of protocols and any comb inat ion of available e lec tric al i nte rfac es and me dia . T he Ci sco 7576 consists o f two independent Cisco 7500 series routers configured on a single split backplane. This system is housed within the chassis footprint of a Cisco 7513 router.

Network interfaces reside on interface processors that provide a direct connection between the two independent dual CyBuses located on the backplane of the Cisco 7576 and your external networks. The two independent dual CyB uses facilitate the configuration of two independent routers on a single backplane. T hes e r out ers are i de nti fied as rou t er A a nd r oute r B.

The backplane of the Cisco 7576 has 13 slots. Router A uses in ter face proc essor sl ots 0 thro ugh 5 with a Route Switch Processor (RSP4/4+ or RSP8) in slot 6. Router B uses interface processor slots 8 through 12 with a Route Switch Processor (RSP4/4+ or RSP8) in slot 7. The Ci sco 7576 supports 10 V IPs, one for each interface processor slot; 6 VIPs are supported in Router A and 5 VIPs are supported in Router B.

Caution Because of agency compliance and safety i ssues, mixi ng AC-input and DC-in put power suppl ies in t he

same Cisco 7576 i s not a sup por ted co nfigurati on a nd shoul d n ot b e at te mpted. D oin g so mig ht c ause damage.

Note The Cisco 7576 is s old as a new unit and as an upgrade kit to the Cisco 7513. When purchased new,

the Cisco 7576 comes standard with two AC-input power supplies and two RSP4/4+s. The Cisco 7576 upgrade kit includes only the system chassis, which includes the card cage and backplane. The u pgrad e kit d oes not inc lude p ower suppl ie s, RSPs, or int erfac e pr oc esso rs. T he se parts are exchanged with the parts from the Cisco 7513 unit that is being upgraded.

Although no monitoring of ±12V or temperature is done by the RSP2, a comparat or device ensures that ±12V is maintained within the normal operating ranges, and three temperature sen sors on the RSP2 send temperature information to the chassis interface (CI) card. The C I card reports all voltage and temperature readin gs, and thes e read ings ar e available through stand ard softwa re comma nds for environmental monitoring.

The RSP2 uses a s oftware -cont r olled configur ation r egister, so you do not have to rem ove the R SP2 to configure jumpers. Ther e are no user-configurabl e jumpe rs on the RSP2.

The RSP2 contains the following co mponent s:

• R4600— Reduced Instruction Set Comp uting (RI SC) pro cessor, used for the CPU. The CPU runs at

an external cloc k sp eed of 50 MH z an d an i nte rna l c loc k s peed of 10 0 MHz .

• Most of the memory components used by the syst em , i n cluding onboard Flash memor y. (A bank of

hardware [MAC-layer] addre sse s fo r t he i nte rfac e po rt s is co nta in ed i n an N V RAM device on t he backplane.)

• Air-temperature sensors for environmental monitoring. (All of the logic for the environmental

monitoring funct ions is cont ai ned o n t he ch assis i nter face ca r d.)

In addition to the system software, the RSP2 contains and executes the following management functions that control the system:

• Sending and receiving routing prot ocol updat es.

• Managing tables a nd cache s.

• Monitoring interface and environmental status.

The RSP2 supports high system availability (HSA), which is a feature in Cisco IOS Release 1 1.1(4) or later, allowing two RSPs to be used i n a Ci sco 7507, Cisco 7507 -MX, C isco 7513, or Cisco 75 13-MX router.

Note The Cisco 7576 uses only one RSP slot per router, designated router A and router B; therefore, it does

not support HSA. The Cisco 7505 has only one RSP slot; therefore, it also does not support the HSA feature.

The RSP2 ships as Product Numbers RSP2 and RSP2=. The RSP2 contains most of the memory components used by the system. Table 1-7 lists the functions of

Although no monitoring of ± 12V or tem peratu re is done by the RSP4/4 +, a compa rator device ens ures that ±12V is maintained within the normal operating ranges, and three temperature sensors on the RSP4/4+ send temperature information to the chassis inter face (CI) card . The CI card reports all v oltage and temperatu re r ea ding s, an d th ese rea din gs a re available thr ough st anda rd soft ware comm a nds for environmental monitoring. The RSP4/4+ uses a software-controlled configuration register, so you do not have to remove the RSP4/4+, to configure jumper s. Ther e are no us er-configurable jumpers on t he RSP4/4+.

Route Switch Processor Overview

The RSP4/4+ contains the following components:

• IDT R5000 Reduced Instruction Set Computing (RISC) processor, used for the CPU. The CPU runs

at an external bus clock speed of 100 MHz and an int ernal clock spee d of 200 MHz.

• Up to 256 megabytes (MB ) of pa rity-p rot ec ted, dyna mic r andom -a cce ss mem or y ( DRA M) o n two

dual in-line mem ory m odule s (DIM M s); 3 2 M B of D RA M i s th e de fault sh ippi ng configu ratio n.

• 2 MB of parity-protected, static random-access memory (SRAM) for packet buffering, and 512 KB

of SRAM for secondary CPU cach e memory fu nctio ns. (SRAM is not user- configurable.)

• Most of the ad ditio nal mem ory co mpone nts use d by th e syste m, i ncl uding o nboar d Fla sh memo ry

and up to two PC Cards. (A bank of hardware [MAC-layer] addr esses for the interface port is contained in an NV RA M device on the r oute r backp l an e.)

• Air-temperature sensors for environmental monitoring. (All of the logic for the environmental

monitoring func tions is c onta ine d on th e rout er int erfac e c ar d.)

In addition to r unni ng the system sof tware fro m DRA M, t he R SP4/ 4+ c onta ins an d executes t h e following management functions that control the system:

• Sending and receiving routing prot ocol updat es.

• Managing tables a nd cache s.

• Monitoring interface and environmental status.

• Providing Simple Network Management Protocol (SNMP) management and the interface between

the console an d Telnet.

• Combining all of the swi tc hed r outi ng a nd high -spee d switchi ng func tio ns th at c ommu nica te w it h

and control the interfac e processo rs on the dual CyBus. Th is switchin g section dec ides the destination of a packet and switches it accordingly.

The RSP4/4+ supports high system availability (HSA), which is a feature in Cisco IOS Release 11.1(4) or later, allowing two RSPs to be used in a Cisco 7507, Cisco 7507-MX, Cisco 7513, or Cisco 7513-MX router. By default, the system master is the RSP that occupies the first RSP slot in the router: slot 2 in the Cisco 7507, and slot 6 in the Cisco 7513.

Note The Cisco 7576 uses only one RSP slot per router, designated router A and router B; therefore, it does

not support HSA. The Cisco 7505 has only one RSP slot; therefore, it also does not support the HSA feature. The RSPs in these models are automatically the system master for their respective routers.

The RSP4/4+ ships as the following product numbers:

• As a spare part , a s P r odu ct N u mber RS P4=

• Bundled with and installed in Cisco 7500 series routers, as the following product numbers:

–

RSP16—Cisco 7507, Cisco 7507-MX, Cisco 7513, and Cisco 7513-MX

The RSP16 is the latest-genera tion, main syst em processo r module for the Cisco 7500 series rout ers. The RSP16 supports the high system availability (HSA) feature, which allows two RSP16s (or an RSP16

and an RSP8) to be u sed in a Cisc o 750 7, Ci sco 7 507 -M X, C isco 75 13, o r C isco 75 13-MX rou ter. The redundancy increases system availability during planned and unplanned network outages..

The RSP16 also supports high availability (HA), a series of features that operates similarly to HSA, but which further minimizes system downtime. (HSA is the system default.)

The RSP16 is not available as an u pgr ad e to an existing R SP, but supports the VIP2, VIP4 , an d new VIP6-80. The RSP16 doe s not su pport legacy inte rface p roce ssors , exce pt f or t he CI P2, GEI P, GEIP+, FEIP2-DSW-2TX, FEIP2-DSW-2FX, SRPIP, CX-CIP2-ECA1 and E CA2.

Common RSP Hardware Features

This section discusses hardware features common to all RSPs. (For convenience, the RSP2, RSP4/4+, RSP8, and RSP16 are referred to as the RSP with differences clearly noted.)

RSP LEDs

Several LEDs on the RSP indicate system and RSP status, as follows:

• Normal LED—On when the RSP is receiving +5V, this LED indicates a successful boot; however,

it does not indicate the system has reached “normal” opera tion.

• CPU halt LED—Off during normal opera ti on, t his LE D go es on on ly i f the syst em det ect s a

processor hardwa re fai lur e. The RSP controls the normal and CPU halt LEDs and turns them on in parallel to indicate that the

system is operational.

• Master/slave LEDs—These LEDs indicate whether an RSP2, RSP4/4+, or RSP8 is the master or

slave in a system configured for the high system availability (HSA) feature.

• Slot 0 and slot 1 PC Card LEDs—These LEDs go on when a PC Card-based Flash memory card is

being accessed in the respective PC Card slot.

Note The master/slave LED and the HSA feat ure are not supp orted on t he Cisco 7505 or Cisco 7576.

RSP DRAM

Dynamic random-acc e ss mem ory ( D RAM) stor es rout ing tab les, prot ocol s, a nd ne twork acc ount ing applications. Table 1-11 lists the RSP DRAM configurations.

2. Do not mix memory sizes. If installing 2 DIMMs, both DIMMs must be the same size. If your router includes redundant RSPs, the RSPs should have the same memory size.

3. SRAM is not user-configurable or field-upgradable.

4. A system co nfiguratio n file is contained in NVRAM, which allows the Cisc o I O S software to control several system variables.

5. This 16-MB SIMM Flash memory is not supported on the RSP2, RSP4/4+, or RSP8.

6. A 64-MB Flash Disk is the default shipping configuration for the RSP16 product.

Route Switch Processor Overview

Caution To prevent memory problems, DRAM DIMMS must be 3.3V devices. Do not attempt to install

higher-voltage devices (such as those designed for the RSP2) in the RSP4/4+ or RSP8 D IMM sockets.

RSP SRAM

RSP static random-access memory (SRAM) provides packet buffering and CPU cache memory functions. Table 1-12 lists the RSP SRAM configurations.

RSP NVRAM

RSP nonvolatile random-access memory (NVRAM) stores the system configuration and the environmenta l monitorin g logs. It is backed up wit h bu ilt-in lith ium batteri es that retain th e conten ts for a minimum of 5 years.

Note Before replacing an RSP, back up the running configuration to a Trivial File Transfer Protocol

(TFTP) file server so that you can later retrieve it. If the configuration is not saved, the entire configuration will be lost—inside the NVRAM on the remo v ed RSP—and you will ha v e to r eenter it manually . This proce dure is not necessary if yo u are temporarily rem oving an RSP you will reinstall; lithium batteries retain the configuration in memory until you replace the RSP in the system.

RSP Flash Memory

Flash memory, either on a SIMM or on a Flash memory PC Card or Flash Disk, allows you to remotely load and store multiple Cisco IOS software and microcode images and to back up configurations on your Cisco 7500 serie s rout er.

You can download a new image over the network or from a local server and then add the new image to Flash memory or replace the existing files. You can then boot the routers either manually or automatically from any of the stored images. Flash memory also functions as a TFTP server to allow other servers to remotely boot from stored im ages or to copy them into their own Flash memory.

Note For specific Flash memory card procedures, see the “Using the Flash Memory Cards in the RSPs”

section on page 4-20.

RSP EEPROM

An electrically erasable programmable read-only memory (EEPROM) component on the RSP stores board-specific infor mat ion s uch a s the boa rd se ria l nu mb er, part nu mbe r, controlle r t ype, ha rdwar e revision, and other details unique to each board. This EEPROM is not a spare and cannot be programmed in the field.

RSP Asynchronous Serial Ports—Console and Auxiliary

Two asyn chron ous EIA/TIA -232 serial ports on th e RSP, the console and auxiliary ports, provide the means for connecting a ter minal , modem, CSU , DSU, or othe r external device for co nfiguring, managing, or connectin g to the syst em. A data c ircuit- termina ting eq uipment (D CE) EIA/ TIA-2 32 receptacle con sole po rt o n the RSP p rovid es a dir ec t c onnec ti on fo r a co nsole te rmin al.

Note EIA/TIA-232 was known as recomm ende d standar d RS-23 2 before its a ccept ance as a st andar d by

the Electronic Industries Association (EIA) and Telecommunications Industry Association (TIA).

The adjacent DTE EIA/TIA-232 plug auxiliary port supports flow control and is often used to connect a modem, a DSU/CSU, or other opt ional eq uipment for Telnet management of the attac hed device.

The console and auxiliary por ts suppor t as ynchrono us transmission . Async hrono us tr ansmission uses control bits to indicate the beginning and end of cha racters, rather tha n precise timing. Serial int erface ports on serial inte rface p roce ssors a nd port ada pters suppo rt sy nc hro nous t ransm ission, whi ch maintains precise clocking between the transmitter and receiver by sending frames of informatio n that consist of separate clock signals along with the data signals.

Arbiter Overview

In the Cisco 7500 se rie s r oute rs, a n int erna l prin ted ci rcu it board c alle d th e arbit er arbitrates traffic on the CyBus and generates the CyBu s cl ock.

The Cisco 7505 has a single ar biter, whereas the Ci sco 7507 and Cisco 7 513 have a dual a rbit er for the dual CyBuses. The Cisc o 7576 includes t wo dua l a rbit ers, on e for rou ter A and on e for r oute r B. Th e arbiter is attached dire ctly to the fr ont ( nonin terf ace p roce ssor s ide) o f the system back plan e. It co ntro ls traffic across each CyBus by prioritizing access requests from interface processors to ensure that each request is processed and to prevent any interface proc essor from jeo pardiz ing each CyBu s and interfering with the ability of the other interface processors to access the RSP.

The arbiter provides the following services for the system:

• CyBus clock genera tion—Generates the inter nal system cloc k and provides a private copy of the

clock to th e RS P an d e ach i nte rfac e pr oc essor.

• CyBus arbitration—Arbitrates interfac e processo r requests to tra nsmit comm ands on the CyB us.

The arbitration is based on a round-robin priority scheme to ensure that all interface processors have access to a known portion of each CyBus’s bandwidth.

• Global lock arbitration—Arbitrates interfac e pr oces s or an d R SP r equ es ts fo r th e gl ob al lo ck , a

synchronization primitive used to control RSP and i nterface proc essor acce ss to shared data structures.

Note The Cisco 7507-MX, Cisco 7513-MX, and some models of the Cisco 7507 and Cisco 7513 ship with

the Cisco turbo arbiter. The turbo arbiter, when used in conjunction with other future hardware, significantly increa ses system b andwidth . When no t used wit h this f uture ha rdware, the turbo ar biter operates in standa rd CyBus m ode . Re fer to Re placing the Dual Arbiter or

Chassis Interface Overview

The Cisco 7500 se rie s r outers have an in tern al pr in ted bo ar d c alle d t he chassis interface (CI) that provides the environmental and p ower supply mo nito ring f unct ions for the rout er. (See Figure 1-30.)

Note The CI is available as a FRU. The Cisco 7576 includes two chassi s interface s, one for ro uter A and

one for router B.

Chapter 1 Cisco 7500 Series Product Overview

Fan Tray and Blower Assembly Overview

Figure 1-30 7500 Series Chassis Interface

The CI isolates the CPU and sys tem software from chass is-specific variations, and is attached directly to the front (noninterface processor side) of the system backplane.

The functions of the CI are as follows:

• Report backplane t ype an d ar biter type

• Monitor power supply and fan and blower status

• Monitor the temperature sensors on the RSP

• Provide router power up /down co ntrol and power su pply power-down contro l

Note In the Cisco 7513 and Ci sco 7513-M X, a ha rd s hutdown is ac hieved by disabling the power sou rce.

In the Cisco 757 6, bo th r oute rs sha re t he sam e power source . In t he Ci sco 7576, when one rou ter senses a problem requiring a hard shutdown, the RSP and all interface processor s install ed in that router (only) are powered off. In the first 14 tempe rature cycles, the RSP and interface pro cessors are powered back on once the tem pe rat ure o f th e syst em fall s be low a cert ai n te mper at ure se tpoint . At the fifteenth temperature cycle, this temperature setpoint is changed to a very low value, pr eventing the affected router f rom p owering back up .

This achieves a hard shutdown of one router without affecting the other router. The RSP and interface processors will remain disabled until the power is manually recycled. This allows you to choose a suitable time to recycle the power when it will not adversely affect your users.

For CI maintenance information, see “Removing and Replacing the Chassis Interface in the Cisco 7505”

section on page 5-11, “Removing and Repl aci ng t he Ch as sis Inte rface in t he C is co 75 07 an d C isco 7507-MX” section on page 6-12, and “Removing and Replac ing the Chassis Interface in the Cisco 7513, Cisco 7513-MX, and Ci sco 7576” section on page 7-14.

Fan Tray and Blower Assembly Overview

Blower and fan tray assemblies cool the inter ior o f the Cisco 7505 router chassi s. It m ay be difficult to determine whethe r or no t the fans or b l owers are o pe ra ting i n noi sy, air-conditioned room s. If you determine that they are not operating, contact a customer service representative immediately. There are no installation adjustments th at you should make if the fan or blower assembly does not function properly at initial startup .

Interface Processor Overview

Interface processor s fo r t he Cisco 7500 series route rs are se para te pro ce ssor m odu les tha t a re inst al led in the routers’ interface processor slots and attach to the system backplane.

Note For complete information on each of the interface processors available for the Cisco 7500 series

routers, refer to the co mpanion publication Interface Processor Installation and Configuration Guide, and to the individual configuration notes that ship with each of the interface processors.

Each interface processor comprises a modular, self-contain ed interface (printed circuit) board and one or more network interface co nnectors in a single 11 x 14-inch unit . You can install and remov e inter face processors without openi ng the chassi s (known as online inserti on and removal, or OIR) and withou t turning off the chassis power.

The microcode on eac h interfa ce p roce ssor cont ain s boa rd-spe cific software instr uct ions. New features and enhancements to the syste m or inter faces are oft en implem ente d in micr ocode upgr ades.

Each interface processor (and the Cisco 7500 series router in which it is installed) supports downloadable microc ode, w hic h ena ble s y ou to d ownload new microc od e ima ges r em ote ly a nd stor e them in Flash memory. You can then use software commands to load a specific microcode image from Flash memory.

Each interface p roce ssor has a uniqu e bank of sta tus L E Ds, a nd al l have a co mmo n LED (ca lle d t he enabled LED) on the interface processo r’s faceplate. The enabled LED lights when the interface processor has completed its initialization, indicatin g that as a minimum, the interface processor is correctly connected to the backplane, that it is receiving power, and that it contains a valid microcode version. If any of these conditions is not met, or if the initialization fails for other reasons, the enabled LED does not light. Ad dition al LEDs on each interf ac e proces sor ty pe ind icate t he stat e of the interf aces.

The following interface processors are available for the Cisco 7500 series routers:

• AIP—Asynchronous Transfer Mo de (ATM) Interface Processor, with one TAXI 4B/5B,

Safety Recommendations

Caution To prevent damage to the chassis and components, never attempt to lift the chassis by the plastic panels

on the front of the chassis, or by the handles on power supplies or processor modules. These panels and handles were not d esign ed to sup por t the w eig ht o f the ch ass is.

Figure 2-1 Lifting Safe ly (Cisco 7507 Shown)

In general, whe never you lift a Cisc o 7500 se rie s c hassis, fo llow the se guid eline s:

• Whenever possible, avoid lifting the chassis alone.

• Ensure that your footing is solid, a nd balance the weight of the objec t betwee n your feet .

• Lift the chassis slowly; never move suddenl y or twis t y our b ody a s yo u lif t.

• Keep your back straight and lift with your l egs, not your back. If you must bend down to lift the

chassis, bend at the knees, not at the waist, to reduce the strain on your lower back muscles.

• Whenever possible, lift a chassi s fro m the bott om; gra sp th e und ersi de of t he c hassi s exteri or w ith

both hands.

• Always disconnect all external cabl es before lift ing or moving the c hassis.

• For the Cisco 7507, Cisco 7507-MX, Cisco 7513, Cisco 7513-MX, and Cisco 7576, we recommend

you lift the chassis with power supplies removed; use both han ds whe n handl ing the chassi s power supply.

Caution To prevent damage, never attempt to lift or tilt the chassis with the handles on the interface processor

carriers. These handles are not designed to support the weight of the chassis.

Warning

A Cisco 7513 or Cisco 7576 chassis weighs approximately 160 lb (72.6 kg) fully configured. To prevent injury, have someone help you lift the chassis.

Note We re commend that you reduc e the weight of the Cisco 751 3, Cisco 7513-M X, or Cisco 7576 by

removing the blower modul e, p roce ssor m odul es, power sup pli es, a nd c ard c age asse mbly be fo re installation; however, this is not requir ed.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when electronic components are impro perly handled and can result in intermittent or complete failures. Always ensure that the chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good ski n contac t. To safely channel unwanted ESD voltages to ground, connect the clip to an unpainted surface of the chassis frame. If no wrist strap is available, ground yourself to the metal chassis.

Caution For safety, pe riodically check the resistance value of the ESD-preventive wrist strap, which should be

between 1 and 10 megohms.

AC-Input and DC-Input Power Guidelines

The wide-input AC-input power sup pli es i n the Cisco 75 00 se ries ro ut ers u se a power fact or c orr ect or (PFC) that allows th e router to operate on input voltage and current within the AC-voltage range of 100 to 240 VAC and 50 to 60 Hz.

In Chapter 1, Table 1-1 (fo r th e Cisco 7505), Table 1-2 (for the Cisco 7507), Table 1-3 (for t he Ci sco 7507-MX), Table 1-4 (for the Cisc o 7513 ), Table 1-5 (for the Cisco 7513-MX), and Table 1-6 (for the Cisco 7576) list system power specifications, including input voltage and operating frequency ranges. The power supplies in the Cisco 7507, Cisco 750 7-MX, Cisc o 7513, Cisco 7513-MX, and Cisco 7576 routers have two safety interlock features as shown inFigure 2-4 . A locking device on each power supply prevents the power supply from bei ng r em oved from t he ch assis w hen the power s upply sw it ch i s o n. When the switch is in the on (|) position, a metal locking device extends into a slot in the chassis. When the switch is in the of f (O) positi on, the l ocking d e vic e is raised an d cl ears the slot. Also, a r etention c lip prevents the AC-input power supply power cable from being accidentally pulled out of the power supply socket.

For additional po wer supply info rmation, se e the “AC-Input and DC-Input Power Guidelines” section on

page 2-7. Check the power at your site before installation and periodically after installation to ensure

that you are receiving clean p ower; install a power conditioner if necessary. We recommend that you install a power conditioner b etw ee n the AC power source and the rou t er to help avoid problems cause d by power spikes and brownouts, and to help protect agains t equipm ent dama ge fro m lightning st rikes. We al so re c ommen d an un int errup tib le power s ource ( UPS) f or the r oute r to p rote ct agai nst p ower failures at your site.

Chapter 2 Preparing for Installation

AC-Input and DC-Input Power Guidelines

The 600W DC-input power supply allows the Cisco 7505 to operate between –40 and –52 VDC in North America (–48 VDC nominal) a nd bet wee n –56 and –72 VDC in the European Union (–60 VDC nominal). We recommend that y ou use a n 8-AWG, highly flexible str an ded ca bl e fo r th e D C p ower connections. (See Table 1-1 for a list of Cisco 7505 power specifications.)

Note The Cisco 7505 installation must comply with all applicable codes and is approved for use with copper

conductors only. The ground bond fastening hard ware should be of compati ble mate rial and pr eclude loosening, deterioration, and electrochemical corrosion of hardware and joined material. Attachment of the chassis ground t o the cent r al o ffice or other i nte rior ground sys tem sho uld b e made w ith a 6- AWG, copper ground conductor a t a minimum. Th e Cisco 7505 c hassis employs two threa ded M5 chassi s grounding receptacle s, whic h are intend ed to be bond ed direc tly to the cen tral office or other interi or ground system. These receptacles are located on the rear of the chassis. The chassis ground requires M5 screws and locking hardware, w hich are not incl uded .

Cisco 7507 and Cisco 7507-MX Power Considerations

The 700W AC-input power supply for the Cisco 7507 and Cisco 7507-M X routers use s a power factor corrector (PFC) that allows it to operate on input voltage and current within the range of 100 through 240 VAC and 47 through 63 Hz. The 700 W DC-inpu t power supply allows the Cisco 7507 and Cisco 7507-MX to op erat e b et we en –40 and –72 VDC (–48 VDC nominal). We recommend that you use an 8-AWG , high ly flexibl e str an ded ca ble fo r th e D C p ower conn ect ions. ( See Table 1-2 and Table 1-3for a list of Cisco 750 7 a nd Cisc o 750 7-M X p ower spec ifications.)

Note The Cisco 7507 or Cisc o 750 7-MX in stall ation m ust c om ply with a ll ap pl icabl e c odes an d is ap proved

for use with c opp er c on duct ors only. The ground bon d fa steni ng h ar dware sh ould be o f c om pat ible material and preclu de loose ning, de terio ration, and elec troche mical corrosi on of hard ware and join ed material. Attac hmen t of the c hassi s grou nd to t h e ce ntr al office or othe r int erio r gro und sy stem sho uld be made with a 6- AWG, copper ground co ndu cto r a t a mi nimu m. The Cisc o 7507 a nd Cisc o 750 7-MX chassis employs two thr eade d M5 cha ssis g rou nding r ecept acles, wh ich ar e i nte nded to b e bon ded directly to the central office or other interior ground system. These receptacles are located on the rear of the chassis. The chassis gro und req uires M5 screws and lock ing hardwa re, whic h are not incl uded .

A second, identical power supply is also present in routers configured with the redundant power option; this ensures that power to the chassis co ntin ues uninter r upted if one power supply fails. It also provides uninterrupted power if the input power line fails, but only if the po wer supplies are c onnected to separate input lines.

Whenever possible, provide redundant power sources for each power supply installed in the chassis. For AC-input installations, install an uninterruptible power source where possible. Install proper grounding to avoid damage from lightning and power surges.

If only one input line is available, and you must connect both power supplies to the same source, the redundant power supply will provide continuous power if the first power supply fails. It cannot provide power backup if the input power fails.

Warning

This unit might have more than one power cord. To reduce the risk of electric shock, disconnect the two power supply cords before servicing the unit.

Plant Wiring Guidelines

This section provides guidelines for settin g up the plan t wiring an d cabli ng at you r site. When plannin g the location of the new system, consider wiring issues, distance limitations for signaling, electromagnetic interference, and connector compatibility, as described in the sections that follow.

Interference Considerations with Cabling

When wires a re r un for a ny signi ficant dist an ce i n an el e ctro ma gn etic field, in te rf eren ce c an oc cur between the field and the signals on the wires. This fact has two implications for the construction of plant wiring:

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

• Strong electromagnetic interference (EMI), especially as caused by lightning or radio transmitters,

can destroy the sig nal d ri v ers a nd r ecei v er s in th e route r, and can even cr eate an e lect rical h azar d b y conducting power surges through lines and into equipment. (Review the safety warnings in the

“Safety Recommendations” section on page 2-2.)

Chapter 2 Preparing for Installatio n

Plant Wiring Guidelines

Note To predict and remedy st rong EMI, you might ne ed to consult exper ts in radio freq uency

interference (RFI).

If you use twisted-pair cable in your plant wiring with a good distribution of ground ing conductors, the plant wiring is unlikely to emit radio interference. When exceeding the recommended distances, use a high-quality twisted-pair cable with one grou nd c onducto r for each data signa l.

If wires exceed recommen ded distanc es, or if wir es pass betwe en buildings, give special cons iderati on to the effect o f a lig h tning strike in your vicinity. The electromagnetic puls e (EM P ) ca us e d by lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic devices. If yo u h ave had pro blem s o f t his so rt in the past , yo u m ight wan t t o con sul t expe rts in electrical surge suppression and shielding.

Most data centers cannot resolve the infrequent but potentially catastro phic problems just described without pulse meters and other special equipm ent. These problems can cost a great deal of time to identify and resolve, so take precautions by providing a properly grounded and shielded environment, with special attention to issues of electrical su rge suppression.

Warning

When stranded wiring is required, use approved wiring terminations, such as closed-loop or spade-type with upturned lugs. These terminations should be the appropriate size for the wires and should clamp both the insulation and conductor.

Warning

T o be installed and maintained by service personnel as defined by AS/NZS 3260. Incorrect connection of this or connected equipment to a General Purpose Outlet could result in a hazardous situation. The telecommunication lines must be disconnected before unplugging the main power connection and while the housing is open.

Warning

Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is availabl e.

Distance Limitations of Interface Cabling

The length of your networks a nd the dista nce betwe en conne ctions depend on the ty pe of signal, the signal speed, and the transmission media (the type of cabling used to transmit the signals). For example, standard coaxial cable has a greater channel capacity than twisted-pair cabling.

The distance and rate limits for the a v aila ble elect rical interfac es supported b y Cisco 750 0 series routers are recommended maxi mum spe eds and dista nces for signal ing. If you unders tand the elec tric al problems that might arise and can compensate for them, you might get good results with faster rates and greater distances ; however, do so at your own risk .

Note We re co mm end tha t y ou do no t exceed specified transmission rate and distance limits for interface

cabling.

specifications for the electrical interfaces supported by the Cisco 7500 series routers, refer to the companion publication Interface Processor Installation and Configuration Guide .

Site Environment, Chassis Temperature, and Airflow Guidelines

Cisco 7500 series routers can opera te as standal one systems pl aced on a table or as rack-m ounted systems in a data proc essi ng or l ab e nvironment. (We recommend rack-mounti ng for a ll Ci sco 750 0 series routers.)

The internal fan or blower operates so that it maintains an acceptable operating temperature inside the chassis. The router requi re s a dry, clean, well-ventilated , and air-conditioned environment. The in ter nal blower pulls ambien t air thr ough the chassis to cool the internal comp onents. To allow suff icie nt airflo w, maintain a mini mum of 2 i nch es (5. 08 cm) of cl eara nc e a t bo th t he in let and exha ust openi ng s on the chassis. If the airflo w is blocked or restricted, or if the inle t air is too warm, an ov ertemperature conditio n can occur. Under e xtrem e conditions, th e environmental monitoring system will shut down the power to protect the syst em c om pon en ts.

T o help maintain normal operation and avoid unnecessary maintenance, plan your site configuration and prepare your site before installation. After installation, make sure that the site maintains an ambient temperature of 32 through 10 4°F (0 through 40°C), and keep the ar ea around the chassi s as free fro m dust as is practical. For a description of the environmental monitor and status levels, see the

“Environmental Monitori ng a nd Repor tin g Overv iew for the Cisc o 7500 Series” section on page 2-22.

If the temperature of the air drawn into the chassis is higher than desira ble, the ai r tempe ratur e inside the chassis m i gh t a l s o be t o o h i g h . T his condition can occur w hen the wiring closet or rack in which the chassis is mounted is not ventilated properly, when the exhaust of one device is placed so it enters the air inlet vent of the chassis, or when the chassis is the top unit in an unventilated rack. Any of these conditions can inhibit airflow and create an overtemperature condition.

Because the inlet air flows into one part of the chassis and out another, other devices can be rack-mounted with as little as 1 inch (2.54 cm) of clearance abo ve and belo w the cha ssis. Howe ver , whe n mounting a router in a rack with ot her equipm ent , or when plac ing it on a table w ith other equipme nt located close by, ensure that the exhaust from other equipment does not blo w into the inlet of the ch assis. The inlet air is drawn in and exhausted as shown in Figure 2-7 (for the Cisco 7505), Figure 2-8 (for the Cisco 7507 and Cisco 7507-MX), and Figure 2-9 (for the Cisco 7513, Cisco 7513-MX, and Cisco 7576).

Table 2-1 lists the operating and nonoperating environmental site requirements. To maintain normal

operation and ensure high syste m a v ail ability, maintain an ambient temperat ure a nd clean p o wer at your site.

The ranges in Table 2-1 are those within which the router will continue to operate; however, a measurement th at is a ppr oach i ng the min im um or m ax imum o f a ra nge i n dica tes a po ten tial pr oble m. You can maintain normal operation by anticipating and correcting environmental anomalies before they approach the maximum operating range.

Th e fans dr aw ai r in t hr ough t he inl et vents o n th e side of the chassis opposite the fans, acro ss the proce ssor modules an d other internal compo nents, an d through the exhaust vents adjacent to the fans.

The sides of the chassis must remain unobstructed to ensur e adequate airflow and prevent overheating inside the chassis. A temperature sensor on the RSP monitors the inter nal air temperature. The power supply has two fans for cooling.

Figure 2-7 shows the chassis fans an d a irf low throug h the Cisco 75 05.

Cisco 7507 and Cisco 7507-MX Airflow Considerations

The system blower on t h e Ci sco 7 507 a nd Cisc o 7 507-M X provide s coo l ing a ir fo r th e pro cessor modules. The blower draws air in through the air filter in the front chassis panel and directs it up through the floor of t he intern al sl ot co mpar tmen t and o v er t he ca rds. The e x haus t air i s for ced o ut th e re ar o f the chassis above and to each side of the pro cessor slots. The blo wer needs a clean air f ilte r in order to dra w in suffic ient amount s of coolin g air; e xcessi ve d ust in the f ilter will restri ct the airf low. Keep the air filt er clean and replace it when necessary.

Figure 2-8 shows the syst em blower a nd air flow throu gh the Cisc o 7507 a nd Cisc o 7507-M X.

Figure 2-8 Airflow Through the Cisco 7507 and Cisco 7507-MX

Sensors on the RSP2 (for example) monitor the inlet and internal chassis air temperatures. If the air temperature at ei the r of the se nsors exc eeds a desi red th resho ld, an environmenta l m onitor di splays warning messages and can interrupt syste m operation to protect the syste m compone nts from possibl e damage from excessive heat or electrical current.

The power supplies have their own fans. An air dam between th e power supply bays and the process or module compartment keeps the airflow constant.

Cisco 7513, Cisco 7513-MX, and Cisco 7576 Airflow Considerations

The blower on the Cisco 7513, Cisco 7513- MX, and Cisco 7576 provid es cooling ai r for the processor modules. The exhaust air is forced out the front of the chassis behind the card cage.

Equipment Rack-Mounting Guidelines

This section provides the equipmen t rack-moun ting guidelin es that must be obser ved before installin g a Cisco 7500 series r out er in a n equi pm ent rac k.

General Equipment Rack Ventilation Considerations

If you plan to i nstal l the rou t er i n an equi p ment r ack, y ou can avoid overtemper a ture cond i tio ns by observing the following p recaut ion s:

• There must be a t least 2 inches (5.08 cm) of clearan ce between each side of the chassis an d the side

(or inner wall) of an enclosed rack.

• Enclosed racks must have adequate ventilation or an exhaus t fan; use an open rack whenever

possible.

• A ventilation system that is too powerful in a closed rack can also prevent cooling by creating

negative pressure around the chassis and redirecting the air away from the inlet vents. If necessary, operate the chassis with the rack open.

• The correct us e of baffles in an encl osed rack ca n help to ens ure th at co ol air re aches the ch assis.

Equipment Rack-Mount ing Guidelines

• Equipment near the bottom of a rack can genera te excessive heat that is drawn upward and into the

inlet ports of equipment above, leading to overtemperature conditions in devices at or near the top of the rack.

In addition, the following sections contain specific rack-mounting guidelines for the Cisco 7500 series routers:

Cisco 7505 Ra ck-M ou nt Cons ide ra tions

The rack-mountin g hardware included w ith the Cisco 75 05 is suitabl e for most 19- inch (48. 26-cm) equipment racks o r 2-p ost r acks. Th e r oute r ch as sis mount s to two po sts or r ails i n the rac k w ith two mounting ears, which attach to the sides of the chassis. Ideally, you should be able to access both the interface processor a nd n oninte rfac e pr oc es sor en ds of the ro ute r wit ho ut having t o rem ove it from t he rack. Before using a part icular ra ck, ch eck for obst ructi ons (such as a power stri p) that coul d impair access to the int erfac e proces sors or ch ass is cover panel .

As an alternat ive, the r oute r ca n be m oun ted on a n eq ui pment shel f p rovided t hat the r ack dim ens ions allow the router to be secured to the shelf, and the overall configuration permits safe installation and access. Figure 2-10 shows the chassis footprint and outer dimensions.

To use the rack-mounting hardware provided with the router, consider the following guidelines:

• To mount the router between two posts or rails using the mounting ears, the inner clearance (the

width between the inner sides of the two posts or rails) must be at least 17.72 inches (45 cm).

• The height of the chassis is 11 inches (27.94 cm) with the chassis feet attached, and 10.5 inches

(26.67 cm) when the chassis feet are removed.

• When mounti ng the r outer i n four -post or 2- post r acks, be sure to use all eight of the scre ws p rovid ed

to secure the chassis ears to the rack posts (use four screws per ear). The ears secure one end of the chassis to two rack posts; the rest of the chassis is cantilevered off the posts. Using fewer than all eight screws might not b e sufficient to s uppo rt t h e w eigh t of the c hassi s.

• If the rack has a vertical power strip or other obstacle, ensure that there is sufficient clearance to

install and remove proc es sor modul es, wh ich mu st b e pul le d str aigh t ou t of the ir slot s.

• Maintain a minimum clearance of 2 inches (5.08 cm) on each side of the chassis for the cooling air

inlet and exhaust ports. Avoid placing the router in an overly congested rac k or direct ly next to another equipment rack. Otherwise, the heated exhaust from other equipment can enter the inlet air vents and cause an overtemp er atur e c ond ition in side th e ro uter.

• Install and use the cable -management b rackets included with the router to ke ep cables or ganiz ed and

out of the way. Consider the equipment and cabling that is already installed in the rack. Ensure that cables from other equipment will not impair access to the interface processors or require you to disconnect cables unn ec essar il y to pe rform e qu ipme nt m a inten ance o r u pgrad es.

• Install heavier equipment in the lower half of the rack to maintain a low center of gravity.

• If you plan to use an equipment shelf, ensure that the shelf is constructed to support the weight and

dimensions of the chassis. Figur e 2-10 shows the chassis footprint, which you will need if you are designing a customized she lf.

• If you use 2-post racks, be sure that the rack is bolted to the floor and secured. One end of the chassis

mounts to the two rack posts with the chassis ears, and the rest of the chassis is cantilevered off the posts. Ensure that the weig ht of the chassis does not make the rack unstable. Some 2-post racks are also secured to ceil ing brackets if warr anted by the we ight of the eq uipm ent i n the ra ck.

Cisco 7507 and Cisco 7507-MX Rack-Mount Considerations

An optional rack-mounting kit is available for mounting the Cisco 7507 or Cisco 7507-MX in a standard 19-inch (48.26 cm) e quipm ent r ack. T he m ountin g k it is no t sui ta ble fo r use w ith 2 -po st e quipm e nt racks, or those wit h ob struc tions (suc h as a power strip) th at cou l d im pair ac cess to the in terfa ce processors and power supplies. In telco environments or at installation sites that use nonstandard racks, the router can be mounte d on an equip ment sh elf, provid ed that the rack dim ensions al low safe installation and access to the power supplies and interface processors. Figure 2-11 shows the chassis footprint and outer dime nsions.

To use the optional rack-mount kit, your equipment rack must meet the following requirements:

• The width of the ra ck, be twee n th e two f ron t m ounti ng str ips or r ail s, must b e 17. 75 inches (45.09

cm).

• The depth of the rack, betw een the front and re ar moun ting strip s, must be at least 19.25 inches

(48.90 cm) but not more than 32 inches (81.28 cm ).

• The height of the chassis is approximately 20 inches (50.08 cm) (19.25 inches [48.90 cm] when the

chassis feet are remo v ed ). Th e rack mus t ha v e sufficient vertical cleara nce t o insert the chass is and, if required after installation, to remove the chassis feet.

• If the rack has a vertical power strip or other potential obstacle, ensure that it will allow sufficient

Cisco 7513, Cisco 7513-MX, and Cisco 7576 Rack-Mount Considerations

The rack-mounting hardware included with the Cisco 7513, Cisco 7513-MX, and Cisco 7576 is suitable for most 19-inch equi p ment r ack s an d 2-p ost r acks. I deall y, you should be abl e t o acce ss bo th t he interface processor and noni nterface processo r ends of the ro uter wit hout having to remove the chas sis from the rack.

The router can be mounted in the rear of a rack. Before using a particular rack, check for obstructions (such as a power strip) that could impair rack-mount installation. If a power strip does impair a rear rack-mount installation, remove the power strip before installing the router in the rack and then replace it after the chassis is installed. As an alternative, th e router can be mounted on an equipment shelf provided that the shelf and rack dimensions allow the router to be secured to the shelf and the overall configuration permits safe installation and access; however, we recommend rack-mount instal l ation for the Cisco 7513, Cisco 7513-MX, and Cisco 7576. Figure 2-12 shows the chassis footpri nt and ou ter dimensions.

To use the rack-mounting hardware provided with the router, consider the following guidelines:

• To mount the router between two posts or rails using the mounting ears, the inner clearance (the

width between the inner sides of the two posts or rails) must be at least 17.72 inches (45 cm).

• The height of the chassis is 33. 75 inches (85.725 c m).

• When mounting the r out er in fo ur-post or 2-post rac ks, be sur e to use all of the s cr ews provided to

secure the chassis to the rack posts. Using fewer than all the screws provided in the rack-mount kit might not be sufficient to support the weight o f the chassis.

• If the rack has a vertical power strip or other obstacle, ensure that there is sufficient clearance to

install and remove proc es sor modul es, wh ich mu st b e pul le d str aigh t ou t of the ir slot s.

Environmental Monitoring and Reporting Overview for the Cisco 7500 Series

In the Cisco 7500 series routers, the environmental monitoring and reporting functions are controlled by the chassis interface (CI) board. These functions enable you to maintain normal system operation by identifying and resolvi ng advers e conditi ons prior to loss of oper ation. Th e environmental monito ring functions constantly monitor the inte rnal chassis air temperature and DC supply voltages and currents.

Each power supply monitors its own voltage and temperature and shuts itself down if it detects a critical condition within the power supply. If conditions reach shu tdown thresholds, the system shuts down to avoid equipment damage fr om excessive heat. The re por tin g func ti ons pe riod ica lly log t he values of measured parameters so that you can retrieve them for analysis later, and the reporting functions display warnings on the con sol e i f any o f th e mo ni tore d pa rame ter s exc eed defined thre shol ds.

In addition to monitoring internal temperature and voltage levels, the system also monitors the fan tray or blower. If the fan tray or blower fails, the system displays a warning message on th e console . If the blower is still not operating properly af ter 2 minutes, the system shuts down to protect the internal components against damag e from excessive heat.
