SFP Module Information
You may have ordered a small form-factor pluggable (SFP) module with your Cisco 7201 router. You must install the SFP module. It is shipped separately to prevent damage during shipment. After reading this section, use the installation instructions in the "Removing and Installing an SFP Module" section on page 4-2 to install the SFP modules.
For ease of installation, insert the SFP module in the router while it is powered down and before placing it in a rack.
The SFP 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 models SFP-GE-S, SFP-GE-L, SFP-GE-Z, and SFP-GE-Fare supported in the Cisco 7201 router, as well as the SFP-GE-T. The cabling information is the same for all optical SFP modules.
Also see the "SFP Module Specifications and Configurations" section on page A-4, and the Gigabit Interface Converter (GBIC) Module and Small Form-Factor Pluggable (SFP) GBIC Module Installation Information and Specifications document at
http://www.cisco.com/en/US/docs/routers/7200/install_and_upgrade/gbic_sfp_modules_install/5067g.html

Note The SFP module must be installed before you connect the cables to it.
•The SPF module has three types of latches, which are also the removal mechanism. See Figure 1-3. There is no correlation of the type of latch to the model (such as SX or LH/LX) or technology type (such as Gigabit Ethernet) of SFP modules. Always read the label on the SFP module to determine the technology type and model.
•You can install and remove Gigabit Ethernet SFP modules with power on to the system.
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
•Disconnect all cables before removing or installing a Gigabit Ethernet SFP module. We strongly recommend that you do not install or remove the SFP module with optical fiber cables attached to it.
•SFP modules are keyed to prevent incorrect insertion.
USB Port Information
The Cisco 7201 provides a USB port that can be used with a USB Flash memory module as secondary storage, and can be used to store Cisco IOS images, data, and configuration files. The Cisco 7201 USB port can also be used with the Aladdin USB eToken Pro key. This USB device can be used for the following functions:
•The Cisco USB Flash memory module can be used to store an image or configuration file like a CompactFlash Disk. Unlike the Aladdin USB eToken Pro key, the Cisco USB Flash memory module is nonsecure. See Table A-5 on page A-4 for available USB token configurations and product numbers.
•The USB eToken Pro key by Aladdin Knowledge Systems provides a secure means to store and deploy information, such as a bootstrap configuration or VPN credentials, separate from the router chassis. The Aladdin USB eToken Pro key uses smart card technology to protect a small area of memory and grants access using a personal identification number (PIN). When IP Security (IPSec) VPN credentials are stored on the Aladdin USB eToken Pro key, they are safely external to the router. When the USB eToken is inserted in a USB port, the router can pass the PIN and unlock it, retrieving the credentials and copying them into running memory. When the Aladdin USB eToken Pro key is removed, the router erases the credentials from running memory, ensuring that they cannot be retrieved from the router itself.
Note For more information about the eToken Pro key by Aladdin Knowledge Systems, see the Aladdin website at www.aladdin.com/etoken/cisco.
Note The Cisco USB Flash memory module cannot be used to boot the router. The USB drivers exist only in Cisco IOS software, not ROM Monitor mode (ROMmon). As a result, a Cisco IOS image must be booted to load the drivers; only then can files be copied to and from the USB Flash memory module.
CompactFlash Disk Information
The Cisco 7201 router has one CompactFlash Disk slot that uses CompactFlash Disks. The device in this slot is always addressed as disk0: when using Cisco IOS command-line interface (CLI) commands.
CompactFlash Disks are smaller in size than Type 2 Flash Disks but provide the same AT Attachment (ATA) interface and equivalent functionality. This interface complies with the ANSI ATA Interface Document X3T13.1153 D Rev. 9 specification. CompactFlash Disks provide from 256 MB of storage.
The CompactFlash Disk has controller circuitry that allows it to emulate a hard disk and automatically maps out bad blocks and performs automatic block erasure. The CompactFlash Disk also provides the capability to allocate noncontiguous sectors, which eliminates the need for the squeeze command (which was required with older-style linear flash memory cards to recover the space used by deleted files).
The CompactFlash Disk also supports the Cisco IOS File System feature, which provides a single interface to all of the router's file systems, including the Flash Disks and flash memory, as well as network file systems such as File Transfer Protocol (FTP) and Trivial FTP (TFTP) servers.
Table A-4 on page A-3 lists the CompactFlash Disk options. Also see Appendix B, "Using the CompactFlash Disk."

Four internal fans draw cooling air into the chassis and across internal components to maintain an acceptable operating temperature. (See Figure 1-4.) The four fans are located at the rear of the chassis, as is the chassis grounding connector that provides a chassis ground connection for ESD equipment or a two-hole grounding lug. Two power supplies, either two AC power supplies or two DC power supplies, are accessed from the rear of the router.
