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 on page 42 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 on page 42 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.)
Figure 10 Identifying a Roll-Over Cable
The Cisco 7201 router ships with a roll-over cable. Connection to a terminal or a modem will require an RJ-45-to-DB-25
adapter, and possibly a DB-25-to-DB9 adapter. Refer to Table 2 for the cable and adapter configurations that can be used to
connect terminals and modems to the Cisco 7201 router.

Connect the Fast Ethernet Management Port Cable
Figure 11 Installing the Fast Ethernet Management Port 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, page 15
•Install the Native Gigabit RJ-45 Ethernet Cables, page 18
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.
Figure 12 Optical SFP Modules and Copper SFP Modules
The optical SFP modules can occupy any of the four optical Gigabit Ethernet ports, 0/0 through 0/3. However, the copper SFP
modules can occupy only optical Gigabit Ethernet ports 0/2 and 0/3.

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.

17
Figure 14 Mode-Conditioning Patch Cord Assembly for an SFP Module
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 at
http://www.cisco.com/en/US/tech/tk482/tk876/technologies_white_paper09186a0080254eba.shtml and the
Compressed Air Cleaning Issues for Fiber-Optic Connections document at
http://www.cisco.com/en/US/tech/tk482/tk611/technologies_white_paper09186a00801b08da.shtml. 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 at
http://www.cisco.com/en/US/tech/tk482/tk611/technologies_white_paper09186a00801b08da.shtml and the
Compressed Air Cleaning Issues for Fiber-Optic Connections document at
http://www.cisco.com/en/US/tech/tk482/tk611/technologies_white_paper09186a00801b08da.shtml.
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
Connect the Cables
Figure 15 RJ-45 Port and Copper SFP RJ-45 Gigabit Ethernet Port Cabling
Step 1 Insert an Gigabit Ethernet RJ-45 cable into Gigabit Ethernet RJ-45 ports 0/0 and 0/1 if you are not using Gigabit
Ethernet SFP optical ports 0/0 and 0/1.
Step 2 Insert an Gigabit Ethernet RJ-45 cable into a copper SFP module in Gigabit Ethernet ports 0/2 and 0/3.
.
Connect the Port Adapter Cables
The instructions for connecting the cables for the port adapter installed in the Cisco 7201 router are contained in the respective
configuration notes for each port adapter. For example, if you are connecting the optical fiber cables for the PA-GE port adapter,
refer to the PA-GE Gigabit Ethernet Port Adapter Installation and Configuration document at
http://www.cisco.com/en/US/docs/interfaces_modules/port_adapters/install_upgrade/ethernet/pa-ge_gigabit_ethernet_install_c
onfig/pa_ge.html
Port adapter documents are also available on the Cisco Documentation DVD.
