Network Processing Engine Description The network processing engines consist of the following components: • Reduced instruction set computing (RISC) microprocessor — The NPE-100 and NPE-150 have an R4700 microprocessor that operates at an internal clock speed of 150 MHz. — The NPE-175 has an RM5270 microprocessor that operates at an internal clock speed of 200 MHz. — The NPE-200 has an R5000 microprocessor that operates at an internal clock speed of 200 MHz.
Network Processing Engine Description • Cache memory — The NPE-100, NPE-150, and NPE-200 have unified cache SRAM that functions as the secondary cache for the microprocessor. (The primary cache is within the microprocessor.) — The NPE-175 and NPE-225 have two levels of cache: a primary that is internal to the processor and a secondary, 2-MB external cache that provides additional high-speed storage for data and instructions.

Network Processing Engine Description Note To prevent DRAM errors in the NPE-100, NPE-150, or NPE-200, and to ensure that your system initializes correctly at startup, DRAM bank 0 (socket U18 and U25, or U11 and U25) must contain no fewer than two SIMMs of the same type. You may also install two SIMMs of the same type in bank 1 (socket U4 and U12, or U42 and U52); however, bank 0 must always contain the two largest SIMMs. Table 2 lists the NPE-175 and NPE-225 memory specifications.

Installation Prerequisites Installation Prerequisites This section provides a list of parts and tools you need to remove and replace the network processing engine in Cisco 7200 series routers and Cisco uBR7200 series routers. This section also includes safety and ESD-prevention guidelines to help you avoid injury to yourself and damage to the equipment. See the “Cisco Connection Online” section on page 38 for ordering and contact information.
Software and Hardware Requirements Note Instructions for replacing the boot ROM and upgrading the Flash SIMM on the I/O controller are contained in the Memory Replacement Instructions publication, which accompanied your new network processing engine.
Installation Prerequisites Table 7 lists the recommended minimum Cisco IOS software release to ensure proper operation of the network processing engine in supported router platforms. Table 7 Network Processing Engine Software and Hardware Requirements Router Platform1 Network Processing Engine NPE-100 NPE-150 NPE-200 NPE-175 NPE-225 NPE-300 Cisco 7200 series • Cisco 7204VXR and Cisco 7206VXR • Cisco 7204 and Cisco 7206 • Cisco 7202 Cisco IOS Release 12.0(2)XE2 or later releases of 12.
Safety Guidelines Safety Guidelines Following are safety guidelines that you should follow when working with any equipment that connects to electrical power or telephone wiring. Warning Only trained and qualified personnel should be allowed to install or replace this equipment. Safety Warnings Warning This warning symbol means danger. You are in a situation that could cause bodily injury.
Installation Prerequisites Advarsel Dette varselsymbolet betyr fare. Du befinner deg i en situasjon som kan føre til personskade. Før du utfører arbeid på utstyr, må du vare oppmerksom på de faremomentene som elektriske kretser innebærer, samt gjøre deg kjent med vanlig praksis når det gjelder å unngå ulykker.
Safety Guidelines Electrostatic Discharge Prevention Electrostatic discharge (ESD) damages equipment and impairs electrical circuitry. ESD occurs when printed circuit boards are improperly handled and results in complete or intermittent failures. The network processing engine, I/O controller, port adapters, and Cisco uBR7200 series cable modem cards consist of printed circuit boards that are fixed in a metal carrier.
Installation Prerequisites Caution Make sure to tighten the captive installation screws on the network processing engine, Cisco uBR7200 series cable modem cards, and the I/O controller (use a number 2 Phillips or a 3/16-inch flat-blade screwdriver). These screws prevent accidental removal, provide proper grounding for the router, and help to ensure that the network processing engine, Cisco uBR7200 series cable modem cards, and the I/O controller are properly seated in the router midplane.

Warning Before completing any of the following steps, and to prevent short-circuit or shock hazards, ensure that power is removed from the DC circuit.
Powering Down the Router and Disconnecting Input Power Step 3 Using a 3/16-inch flat-blade screwdriver, loosen the screw below the +48V lead receptacle and pull the lead from the connector. (For Cisco 7200 series routers, see Figure 13. For Cisco uBR7200 series routers, see Figure 14.) • • For Cisco 7200 series routers, repeat this step for the –48V lead and the ground lead. For Cisco uBR7200 series routers, repeat this step for the –48V lead only.

Removing the Network Processing Engine Step 4 Using a 3/16-inch flat-blade screwdriver, loosen the screws that secure the router to the front mounting strips of the rack. Step 5 Position at least one person in front of the rack to support the front underside of the router. Step 6 From the rear of the rack, carefully push the front of the router out of the rack until there is enough clearance to remove the network processing engine.

If you are returning the network processing engine to the factory, immediately place it in a static shielding bag.
Replacing the Network Processing Engine Replacing the Network Processing Engine To install a new network processing engine in the router, complete the following steps. Note If you are installing an NPE-100 or NPE-150, make sure that you replace the boot ROM on the I/O controller before attempting to boot your router. See the “Software and Hardware Requirements” section on page 12 for network processing engine installation requirements.

Reconnecting Input Power and Powering Up the Router Reconnecting DC-Input Power To reconnect DC-input power to a Cisco 7200 series router or Cisco uBR7200 series router, complete the following steps. Note The color coding of the DC-input power supply leads depends on the color coding of the DC power source at your site. Typically, green or green/yellow is used for ground, black is used for +48V (return), and red or white is used for –48V.

(See Figure 23.) Stripping the DC-Input Leads H8624 0.55 in.
Reconnecting Input Power and Powering Up the Router Note Make sure that the entire stripped end of each lead is inserted all the way into its receptacle. If any exposed wire at the stripped end of a lead is visible after inserting the lead into its receptacle, remove the lead from the receptacle, use the wire stripper to cut the stripped end of the lead, and repeat through Step 5.
Removing and Replacing the Network Processing Engine Step 8 Connect the ground, +48V, and –48V leads to the power source. Note For the Cisco 7200 series, each DC-input power supply operating at –48 VDC in North America requires a minimum of 13A service. Each DC-input power supply operating at –60 VDC in the European Community requires a minimum of 8A service. For the Cisco uBR7200 series routers, each DC-input power supply rating is 14A, 700 volt ampere (VA).
Removing and Replacing an AC-Input or DC-Input Power Supply Caution When the power switch on a Cisco uBR7200 series power supply is turned to the OFF (O) position, the power supply enters a reset cycle for 90 seconds. Wait at least 90 seconds before turning the power switch back to the ON (|) position. If you do not wait the full 90 seconds, the power supply does not restart. Step 2 At the rear of the router, place the power switch on the power supply in the ON (|) position.
Removing and Replacing an AC-Input or DC-Input Power Supply To remove an AC-input or DC-input power supply from a Cisco 7200 series router, complete the following steps: Step 1 Ensure that the power switch on the power supply is in the OFF (0) position and input power is disconnected from the power supply and its power source. (See the “Powering Down the Router and Disconnecting Input Power” section on page 19.
Removing and Replacing an AC-Input or DC-Input Power Supply Replacing a Power Supply in a Cisco 7200 Series Router To install a new AC-input or DC-input power supply in a Cisco 7200 series router, complete the following steps: Step 1 Make sure that the power switch on the power supply is in the OFF (O) position. Step 2 Grasp the power supply handle with one hand and place your other hand underneath the power supply for support. (See Figure 26.
Cisco Connection Online Step 9 Use a 3/16-inch flat-blade screwdriver to tighten the screws that secure the router to the front mounting strips of the rack. Caution To maintain agency compliance requirements and meet EMI emissions standards for the Cisco 7200 series routers with a single power supply, the power supply filler plate must remain in the power supply adjacent to the installed power supply. Do not remove this filler plate from the router unless you intend to install a redundant power supply.
