Rear View

Figure 1-5 Cisco 7304 Router—Rear View

The rear of the Cisco 7304 router has two fan airflow vents. (See Figure 1-5.)

Two replaceable internal fans draw cooling air out of the chassis and across internal components to maintain an acceptable operating temperature. (See Figure 1-5.) The two fans are located at the rear of the chassis.

System Board NSE–100Internally, the NSE-100 contains the following components:

• 256 or 512 MB SDRAM memory1

• Processors

– Reduced instruction set computing (RISC) RM7000 microprocessor that operates at an internal clock speed of 350 Mhz. The RM7000 processor maintains and executes the system management functions for the Cisco 7304 router. The processor also performs some memory and environmental monitoring functions.

– The Parallel eXpress Forwarding (PXF) processors enable parallel IP multipacket processing functions, working with the Route Processor to provide accelerated packet switching, as well as accelerated IP Layer 3 feature processing.

• System controller

The system controller provides hardware logic to interconnect the processors and SDRAM. The Cisco 7304 router has one system controller.

• Cache memory

The processor has three levels of cache: primary and secondary cache that are internal to the microprocessor with secondary unified cache for data and instruction, and tertiary, 2-MB external cache.

• Four environmental sensors for monitoring the internal temperature of the cooling air as it leaves the chassis

• Upgradeable boot ROM for storing sufficient code for booting the Cisco IOS software

System Board—NSE-150Internally, the NSE-150 contains the following components:

• 2 GB SDRAM

• Processors

– Route Processor that maintains and executes the system management functions for the Cisco 7304 router.

– The Parallel eXpress Forwarding (PXF) processors enable parallel IP multipacket processing functions, working with the Route Processor to provide accelerated packet switching, as well as accelerated IP Layer 3 feature processing.

• 2 MB NVRAM for storing the system configuration and environmental monitoring logs. NVRAM uses a lithium battery to maintain its contents when disconnected from power.

• Internal Flash Disk drive (bootdisk:) in addition to the external Flash Drive (disk0:)

• Upgradeable boot ROM for storing sufficient code for booting the Cisco IOS software

• Four environmental sensors for monitoring the internal temperature of the cooling air as it leaves the chassis

1. On November 3, 2003, the 512 MB SDRAM memory option became the default SDRAM memory option for the NSE-100 Processor. The 256 MB SDRAM memory option is still available as a spare, but the 128 MB SDRAM memory option that was once available for the NSE-100 Processor became unavailable for the NSE-100 Processor.


78-13279-01 B0


System Board—NPE-G100Internally, the NPE-G100 contains of the following components:

• BCM 1250 processor system:

– Microprocessor operates at an internal clock speed of 800 Mhz.

– Hardware logic to interconnect the processor, dual double data rate synchronous dynamic random-access memory (DDR-SDRAM), hypertransport (HT) interface, the generic PCI bus, and the two midplanes.

– Cache memory—The NPE-G100 has two levels of cache: primary and secondary cache that are internal to the BCM 1250 processor system with secondary unified cache for data and instruction.

• DDR-SDRAM for providing code, data, and packet storage.

• Three environmental sensors for monitoring the cooling air as it enters, moves across the system board, and leaves the chassis.

• Three Gigabit Ethernet interfaces (six connectors: three Gigabit Ethernet SFP [optical] and three 10/100/1000 RJ-45 [copper]). For each interface, either the Gigabit Ethernet SFP or the RJ-45 port is available. The ports are linked directly to the BCM 1250 processor system.

• CompactFlash Disk: Stores sufficient code for booting the Cisco IOS boot loader image (bootdisk:).

• NVRAM for storing the system configuration and environmental monitoring logs. NVRAM uses a lithium battery to maintain its contents when disconnected from power.

• Upgradeable boot ROM for storing the ROMmon image and upgrading the system to newer versions of the ROMmon image. There are two upgradeable boot ROMs for storing the ROMmon image.

• Non-upgradeable boot ROM provides a “golden copy” of the default ROMmon image.

• Auxiliary port with full data terminal equipment (DTE) functionality.

• Console port with full data communications equipment (DCE) functionality.

• ECC (error correction code) system memory and internal L2 cache support.

System Management FunctionsThe Cisco 7304 performs the following system management functions:

• Sending and receiving routing protocol updates

• Managing tables, caches, and buffers

• Monitoring interface and environmental status

• Providing Simple Network Management Protocol (SNMP) management

• Booting and reloading images

• Managing line cards (including recognition and initialization during online insertion and removal)

• High availability (HA) support and management for two NPE-G100s, one active and one standby

• Routing and forwarding traffic

Caution Two NPE-G100s, two NSE-100s, or two NSE-150s are supported in the Cisco 7304. You cannot use two different processors in the same router, however.

Chapter 1 Overview Checking the Shipping Container Contents

Note For a chassis footprint, additional dimensions, and clearance requirements for the Cisco 7304 router, see the “Preparing to Install the Cisco 7304 Router” section on page 2-1 in Chapter 2, “Installation and Maintenance.”

The Cisco 7304 router supports multiprotocol, multimedia routing and bridging with a wide variety of protocols and line cards.

Checking the Shipping Container ContentsUse the Cisco 7304 Components List to check the contents of the Cisco 7304 router shipping container. Do not discard the shipping container. You need the container if you move or ship the Cisco 7304 router in the future.

Note We no longer ship the entire router documentation set automatically with each system. You must specifically order the documentation as part of the sales order. If you ordered documentation and did not receive it, we will ship the documents to you within 24 hours. To order documents, contact a customer service representative.

Installation ChecklistTo assist you with your installation and to provide a historical record of what was done by whom, photocopy the Cisco 7304 Router Installation Checklist, Table 1-4 on page 1-11. Indicate when each procedure or verification is completed. When the checklist is completed, place it in your site log along with the other records for your new router.
