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
•
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.
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.

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.
CautionIf 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.

1Gray color identifier
5Single-mode bar
2To Gigabit Ethernet interface
6Offset

8To cable plant
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

If your ground wire is insulated, use a wire stripping tool to strip the 18-gauge (or 16-gauge, but not smaller than the supply conductor) ground wire to 0.5 inch (12.7 mm)+ 0.02 inch (0.5 mm) as shown in Figure 21.
Step 4
Slide the open end of the ground lug over the exposed area of the 18-gauge wire.
Step 5
Use a crimping tool to crimp the ground wire to a ground lug.

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

Step 2
Move the circuit-breaker switch handle to the off position, and apply tape to hold it in the off position.
Figure 23 Terminal Block Plug
Step 3
Locate and remove the terminal block plug.
Step 4
Identify the positive and negative feed positions for the terminal block connection. The wiring sequence is positive to positive and negative to negative for both the A and B feed wires.
Figure 24 Positive and Negative Positions
The rear panel of the power supply unit identifies the positive and negative positions for both the A and B feed wires. See Figure 24.
Figure 25 Stripping the DC-Input Power Source Wire
Step 5
Using an 18-gauge wire-stripping tool, strip each of the four wires coming from the DC-input power source to
0.25 inch (6.3 mm) + 0.02 inch (0.5 mm). Do not strip more than 0.29 inch (7.4 mm) of insulation from the wire. Stripping more than the recommended amount of wire can leave exposed wire from the terminal block plug after installation.Warning
An exposed wire lead from a DC-input power source can conduct harmful levels of electricity. Be sure that no exposed portion of the DC-input power source wire extends from the terminal block plug. Statement 122
Figure 26 Inserting Wires into the Terminal Block Plug
Step 6
Insert the exposed wire of one of the four DC-input power source wires into the terminal block plug, as shown in Figure 26. Make sure that you cannot see any wire lead. Only wire with insulation should extend from the terminal block.
Figure 27 Torquing the Terminal Block Plug Captive Screws
CautionDo not overtorque the terminal block plug captive screws. The recommended maximum torque is from 0.5 Nm (4.425 lbf in.) to 0.6 Nm (5.310 lbf in.).
Step 7
Use a ratcheting torque screwdriver to torque the terminal block plug captive screw (above the installed wire lead) to from 0.5 Nm (4.425 lbf in.) to 0.6 Nm (5.310 lbf in.), as shown in Figure 27.
Figure 28 Completed Wiring of Terminal Block Plug
Step 8
Repeat Step 6 and Step 7 for the remaining three DC-input power source wires. Figure 28 shows the completed wiring of a terminal block plug.
Note
Each DC power supply accepts two power feeds, but works with only one. You may choose to install only one power feed per power supply. For example, DC power feed A to the power supply in power supply slot 1 and DC power feed B to the power supply in power supply slot 2.
Figure 29 Inserting the Terminal Block Plug in the Block Header
CautionSecure the wires coming in from the terminal block plug so that they cannot be disturbed by casual contact.
Step 9
Use a tie wrap to secure the wires to the rack, so that the wires are not pulled from the terminal block plug by casual contact. Make sure the tie wrap allows for some slack in the ground wire.
Step 10
Insert the terminal block plug in the terminal block header on the DC power supply panel, as shown in Figure 29.
Step 11
Repeat Step 1 through Step 10 on the second DC power supply.
Step 12
Remove the tape from the circuit-breaker switch handle, and move the circuit-breaker switch handle to the on position.
Step 13
Switch the circuit breaker to the on position.
Step 14
On the front of the router, place the power switch in on (O) the router to turn on the router.
Note
After powering off the router, wait a minimum of 30 seconds before powering it on again.
This completes the procedure for connecting DC-input power. Your installation is complete. Proceed to the "Start the Router" section to start the router.
