Grounding connector |
Five internal fans draw cooling air into the chassis and across internal components to maintain an acceptable operating temperature. (See Figure 1-4.) The five fans are located at the rear of the chassis as is the chassis grounding connector that provide a chassis ground connection for ESD equipment or a two-hole grounding lug.
System Board
Internally, the system board contains the following components:
•Two SODIMM DDR-SDRAM memory modules that are available in three options: 128 MB,
256 MB, and 512 MB
•BCM 1250 processor system
•BCM 1250 integrated dual processor that operates at an internal clock speed of 700 MHz. The
BCM 1250 processor maintains and executes the system management functions for the Cisco 7301 router. The processor also performs some memory and environmental monitoring functions.
–The BCM 1250 serves as the system controller. It interconnects the processor with the double data rate synchronous dynamic random-access memory (DDR-SDRAM) controller, lightning data transport (LDT) bus, and the three direct-interface Gigabit Ethernet interfaces, and the port adapter PCI bus, which allows the port adapter access to DDR-SDRAM.
•Cache memory
The processor system has two levels of cache: primary and secondary cache that are internal to the microprocessor with secondary unified cache for data and instruction.
•Three Gigabit Ethernet interfaces: (six ports: three SFP GBIC [optical] and three RJ-45s [copper]). Any three ports are available at the same time and are linked directly to the BCM 1250 system.
•A CompactFlash Disk for storing the default Cisco IOS software image.
•Auxiliary port with full data terminal equipment (DTE) functionality.
•Boot ROM for storing sufficient code for booting the Cisco IOS software.
•Flash memory for storing the boot helper (boot loader) image.
•NVRAM for storing the system configuration and environmental monitoring logs. NVRAM uses lithium batteries to maintain its contents when disconnected from power.
•Two environmental sensors for monitoring the internal temperature of the chassis.
System Management Functions
The Cisco 7301 processor system 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 through the console and Telnet interface
•Accounting for and switching of data traffic
•Booting and reloading images
•Managing the port adapter (including recognition and initialization during online insertion and removal)
The Cisco 7301 router supports multiprotocol, multimedia routing and bridging with a wide variety of protocols and port adapters.

About the SFP GBIC Module
You may have ordered a SFP (small form-factor pluggable) Gigabit Interface Converter (GBIC) module with your Cisco 7301 router. You must install the SFP GBIC module. It is shipped separately to prevent damage during shipment. After reading this section, use the installation instructions in the "Installing the SFP GBIC Module" section the to install the SFP GBIC modules.
For ease of installation, insert the SFP GBICmodule in the router while it is powered down and before placing it in a rack.
The SFP GBIC port is a 1000-Mbps optical interface in the form of an LC-type duplex port that supports IEEE 802.3z interfaces compliant with the 1000BASEX standard. Gigabit Ethernet SFP GBIC models GLC-SX-MM, GLC-LH-SM, and GLC-ZX-SM are supported in the Cisco 7301 router, as well as the Cisco 1000BASE-T SFP. In addition, a variety of Coarse Wave Division Multiplexing (CWDM) SFPs are supportedon the Cisco 7301. The cabling information is the same for all optical SFPs.
Also see "SFP GBIC Module Configurations" section on page A-4, the Gigabit Interface Converter (GBIC) and Small Form-Factor Pluggable(SFP) GBIC Installation Inforamtion and Specifications, and the Coarse Wavelength-Division Multiplexing SFP Compatability Matrix.
For optical connection cleaning information, see the Inspection and Cleaning Procedures for Fiber-Optic Connections document.

Note The SFP GBIC module must be installed before you connect the cables to it.
•The SPF GBIC module has three types of latches, which are also the removal mechanism. See Figure 1-5. There is no correlation of the type of latch to the model (such as SX or LH) or technology type (such as Gigabit Ethernet) of SFP modules. Always read the label on the SFP GBIC module to determine the technology type, and model.
•You can install and remove Gigabit Ethernet SFP GBIC modules with power on to the system.
•Disconnect all cables before removing or installing a Gigabit Ethernet SFP module. We strongly recommend that you do not install or remove the SFP GBIC with optical fiber cables attached to it.
•SFP GBIC modules are keyed to prevent incorrect insertion.
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
Warning Class 1 laser product. Statement 1008
Warning Class 1 LED product. Statement 1027
Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself. Statement 94

SFP GBIC module |
Use the following procedure to install a SFP GBICmodule:
Step 1 Attach an ESD-preventive wrist strap between you and an unpainted chassis surface.
Step 2 Locate the label on the SFP GBIC module and turn the SFP GBIC module so the label is on top and the alignment groove is down.
Note The SFP GBIC module is keyed so that it cannot be inserted incorrectly.
Step 3 Insert the SFP GBIC module into SFP GBIC port 0/1, 0/2, or 0/3. The SFP GBIC module snaps into place when you have completely and properly inserted it.
Step 4 Repeat Step 2 if you are inserting a second or third SFP GBIC module.
Note Do not remove the plug from the SFP GBIC optical bores until you are ready to install the network interface optical fiber cable. Save the plug for future use.
This completes the SFP GBIC module installation procedure.
