Prepare for Workbench or Tabletop Installation
For a workbench or tabletop installation, verify the following before installing the router:
•The router is off the floor and has adequate ventilation.
•An adequate chassis ground (earth) connection exists for the router.
•The router has at last 3 inches (7.62 cm) of clearance at the inlet and exhaust vents (front and back of router).
•The router has 19 inches (48.26 cm) of clearance at the front and rear to allow for CompactFlash Disk, SFP module, USB module and port adapter replacement or installation, or to access cables or equipment.
•The port adapter blank panel is installed if a port adapter is not installed. The slot must not be empty.
Prepare for Rack-Mount Installation
Before you begin the rack-mounting tasks, decide whether or not you want to front- or rear-mount the chassis, decide whether or not you want to attach the cable-management bracket, and determine the type of rack—four-post or two-post—that you will be using. Also determine if you have any optional field-replaceable units to install, particularly if you are using SFP modules, port adapters, or CompactFlash Disks that are at your site and have not been ordered with the router. See the "After Installation" section for instructions on installing these units.
If you ordered a port adapter, CompactFlash Disk, or SFP module with the router, they ship installed. If you ordered a USB Flash memory module or Aladdin USB eToken Pro key, go to the "After Installation" section for installation information.

Refer to Table 1 for a list of the pins used on the RJ-45-to-DB-25 adapters, used with an RJ-45 cable, to connect terminals and modems to the Cisco 7201 router. The cable you use may be a roll-over cable or a straight-through cable.
A roll-over cable can be detected by comparing the two modular ends of the cable. Holding the cables in your hand, side-by-side, with the tab at the back, the wire connected to the pin on the outside of the left plug should be the same color as the pin on the outside of the right plug. If your cable was purchased from Cisco, pin 1 will be white on one connector, and pin 8 will be white on the other (a roll-over cable reverses pins 1 and 8, 2 and 7, 3 and 6, and 4 and 5). (See Figure 10.)

RJ-45 Fast Ethernet cable

When using the Fast Ethernet Management port in the default mode (speed-auto and duplex-auto) the port operates in auto-MDI/MDI-X mode. The port automatically provides the correct signal connectivity through the Auto-MDI/MDI-X feature. The port automatically senses a crossover or straight-through cable and adapts to it.
However, when the Fast Ethernet Management port is configured to a fixed speed (10 or 100 Mbps) through command-line interface (CLI) commands, the port is forced to MDI mode.
When in a fixed-speed configuration and MDI mode:
•Use a crossover cable to connect to an MDI port
•Use a straight-through cable to connect to an MDI-X port
Connect Native Gigabit Ethernet Cables
The Cisco 7201 router native Gigabit Ethernet ports use either optical fiber or RJ-45 Ethernet cables. For installation information see:
•Install the SFP Module Optical Fiber Cables
•Install the Native Gigabit RJ-45 Ethernet Cables
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. (See Figure 13.)
Appendix A, "Specifications" of the online Cisco 7201 Installation and Configuration Guide, provides cabling specifications and configuration information for the SFP modules that you install in the Gigabit Ethernet SFP ports.
Warning Because invisible laser radiation may be emitted from the aperture of the port when no cable is connected, avoid exposure to laser radiation and do not stare into open apertures. Statement 70
Figure 13 shows the duplex LC-type connectors on your multimode or single-mode optical fiber cables. For simplex connectors, two cables are required, one cable for transmit (TX) and a second cable for receive (RX). For duplex connectors, only one cable that has both TX and RX connectors is required. You can use either simplex or duplex connectors to the SFP ports on the
Cisco 7201 router.
Install the SFP Module Optical Fiber Cables
The SFP module ports support IEEE 802.3z (optical Gigabit Ethernet) interfaces compliant with 1000BASESX and 1000BASELX specifications.
SFP modules ordered with the Cisco 7201 router come installed in the system. Optical fiber cables are commercially available; they are not available from Cisco.

Note We strongly recommend cleaning optical fiber connections before attaching cables to equipment. For information about cleaning fiber-optic cable connectors and receptacles, see the Inspection and Cleaning Procedures for Fiber-Optic Connections document. It provides detailed illustrations and photos of procedures and equipment required to properly clean fiber-optic connections. Also see the Compressed Air Cleaning Issues for Fiber-Optic Connections document.
Warning Class 1 laser product. Statement 1008
Warning Class 1 LED product. Statement 1027
Step 1 Remove the plug from the SFP module so that you can insert the optical fiber cables. Keep the plug for use should you ever disconnect the optical fiber cables.
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
Step 2 Attach the appropriate optical fiber cable directly to the SFP module. You can use either simplex or duplex connectors for most devices. (Figure 13 shows an SFP module with a duplex connector being installed in SFP port 0/1.)
•For simplex connectors, two cables are required, one cable for transmit (TX) and a second cable for receive (RX).
•For duplex connectors, only one cable that has both TX and RX connectors is required.
Caution If you plan to use a SFP-GE-L at distances greater than 984.25 feet (300 meters) over 50/125-micron or 62.5/125-micron multimode fiber, you must use the mode-conditioning patch cord to prevent data transmission problems.
Mode-Conditioning Patch Cord Description
A mode-conditioning patch cord can be used with the SFP-GE-L= (SFP module) to allow reliable laser transmission between the single-mode laser source on the SFP module and a multimode optical fiber cable.
When an unconditioned laser source designed for operation on single-mode optical fiber is directly coupled to a multimode optical fiber cable, an effect known as differential mode delay (DMD) might result in a degradation of the modal bandwidth of the optical fiber cable.
This degradation results in a decrease in the link span (the distance between a transmitter and a receiver) that can be supported reliably. The effect of DMD can be overcome by conditioning the launch characteristics of a laser source. A practical means of performing this conditioning is to use a device called a mode-conditioning patch cord.
A mode-conditioning patch cord is an optical fiber cable assembly that consists of a pair of optical fibers terminated with connector hardware. Specifically, the mode-conditioning patch cord is composed of a single-mode optical fiber permanently coupled off-center (see Offset in Figure 14) to a graded-index multimode optical fiber. Figure 14 shows a diagram of the mode-conditioning patch cord assembly.

The mode-conditioning patch cord assembly is composed of duplex optical fibers, including a single-mode-to-multimode offset launch fiber connected to the transmitter, and a second conventional graded-index multimode optical fiber connected to the receiver. The use of a plug-to-plug patch cord maximizes the power budget of multimode 1000BASE-LX and 1000BASE-LH links.
The mode-conditioning patch cord is required to comply with IEEE standards. The IEEE found that link distances could not be met with certain types of fiber-optic cable cores. The solution is to launch light from the laser at a precise offset from the center, which is accomplished by using the mode-conditioning patch cord. At the output of the patch cord, the SFP-GE-L= is compliant with the IEEE 802.3z standard for 1000BASE-LX.
Note We strongly recommend cleaning optical fiber connections before attaching cables to equipment. See the Inspection and Cleaning Procedures for Fiber-Optic Connections document and the Compressed Air Cleaning Issues for Fiber-Optic Connections document. Figure 14 shows one type of mode-conditioning patch cord.
Attach the Mode-Conditioning Patch Cord
To use a mode-conditioning patch cord, follow these steps:
Step 1 If you have not already done so, and the mode-conditioning patch cord has been in use, we strongly recommend cleaning optical fiber connections before attaching cables to equipment. For information about cleaning fiber-optic cable connectors and receptacles, see the Inspection and Cleaning Procedures for Fiber-Optic Connections document and the Compressed Air Cleaning Issues for Fiber-Optic Connections document.
Step 2 Attach a mode-conditioning patch cord to the SFP module. (See Figure 14.)
Step 3 Attach the network ends of your mode-conditioning patch cord to the appropriate 1000BASEX equipment in your building cable plant.
Ensure that you connect the TX and RX ports on one end of the patch cord to the RX and TX ports (respectively) on the other end. Connect TX to RX and RX to TX.
Install the Native Gigabit RJ-45 Ethernet Cables
This section provides information about installing the native Gigabit Ethernet RJ-45 cables.
Intra-Building Lightning Protection
Shielded cables, which are grounded at both ends, are required to be used on the 10/100/1000 Gigabit Ethernet RJ-45 ports in order to be in compliance with requirement R4-11 in GR-1089-Core for a Central Office environment. This is not a requirement for customer premises installations.
Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables. Statement 1021

The Cisco 7201 has two of the same type of power supplies in power supply slot 1 and power supply slot 2. (See Figure 19.) The power supply slot numbers are on the chassis to the left of the left power supply, and to the right of the right power supply.
Caution Before you connect DC-input power, you must install the DC power ground leads to the DC power supply.
Warning Never install an AC power module and a DC power module in the same chassis. Statement 1050
Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046
Warning Before connecting or disconnecting ground or power wires to the chassis, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. Statement 140
Warning This equipment must be grounded. 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 available. Statement 1024
Caution To make sure that the equipment is reliably connected to earth ground, follow the grounding procedure instructions, and use a UL-listed lug suitable for 6-AWG wire and M5 screws.
Obtain these necessary tools and equipment:
•Ratcheting torque screwdriver with a Phillips head that exerts up to 15 pound force-inches (lbf in.) or 240 ounce force-inches (ozf in.) of pressure
•Panduit crimping tool with optional controlled cycle mechanism
•18-gauge copper ground wire (insulated or noninsulated)
•Four leads of 18-gauge copper wire
•Wire-stripping tool for stripping 18-gauge wire
Install the DC Grounding Leads
To install the DC grounding leads on the DC power supply, follow these instructions.
The DC power supply ships with the DC power supply ground lugs, star washers, and nut attached to the grounding stud on the DC power supply.
Figure 20 Locating the DC Grounding Stud and Grounding Materials
Step 1 Locate the grounding stud on the DC power supply.

Step 6 Place the ground lugs, star washers, and nut on the grounding stud in this order:
a. Star washer
b. Ground lug
c. Star washer
d. Ground lug
e. Nut
Step 7 Tighten the nut to complete the installation.
Step 8 Attach the other end of the ground wires to an appropriate grounding point at your site.
Step 9 Repeat Step 1 through Step 8 on the second DC power supply.
Wire the DC-Input Power Source
Note The color coding of the DC-input power supply leads depends on the color coding of the DC power source at your site. Make certain the lead color coding you choose for the DC-input power supply matches lead color coding used at the DC power source.
Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046
Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than: 120 VAC, 20A U.S. (240 VAC, 10A international). Statement 1005
Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit.
