Software Requirements

The minimum software requirement for the Cisco 7201 router is Cisco IOS Release 12.4(4)XD7, Cisco IOS Release 12.2(31)SB5, or Cisco IOS Release 12.4(15)T1.

To check the minimum software requirements of Cisco IOS software with the hardware installed on your router, Cisco maintains the Software Advisor tool on Cisco.com. This tool does not verify whether modules within a system are compatible, but it does provide the minimum Cisco IOS requirements for individual hardware modules or components.

To access Software Advisor, go to Cisco.com. From the top of the page, choose Support. From the Support drop-down menu, Tools and Resources, click the Software Advisor link. You can also access the tool by pointing your browser directly to http://www.cisco.com/en/US/support/tsd_most_requested_tools.html.

1 A mode-conditioning patch cord is required. Using an ordinary patch cord with MMF, 1000BASE-LX/LH SFP modules, and a short link distance (tens of meters) can cause transceiver saturation resulting in an elevated bit error rate (BER). In addition, when using the LX/LH SFP module with 62.5-micron diameter MMF, you must install a mode-conditioning patch cord between the SFP module and the MMF cable on both the transmit and receive ends of the link. The mode-conditioning patch cord is required for link distances greater than 984 ft (300 m).

Gigabit Ethernet RJ-45 Port Pinouts

The Cisco 7201 router has RJ-45 ports for the two 10/100/1000 Gigabit Ethernet/Fast Ethernet/Ethernet connections. In addition, the Cisco 7201 router has an RJ-45 Fast Ethernet Management port. The RJ-45 ports support IEEE 802.3ab (Gigabit Ethernet) and IEEE 802.3u (Fast Ethernet) interfaces compliant with 10BASET, 100BASETX, and 1000BASET specifications.

The RJ-45 ports support standard straight-through and crossover Category 5 UTP cables with RJ-45 connectors. Cisco does not supply Category 5 UTP cables; these cables are available commercially.

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

Figure A-1 shows an RJ-45 port and connector. Table A-11Table A-11 lists the pinouts and signals for the RJ-45 port.

Note With reference to the RJ-45 pinouts in Table A-11Table A-11, proper common-mode line terminations should be used for the unused Category 5 UTP cable pairs 4/5 and 7/8. Common-mode line termination reduces electromagnetic interference (EMI).

Depending on your RJ-45 interface cabling requirements, use the pinouts shown in Figure A-2 and Figure A-3 for Gigabit Ethernet straight-through and crossover twisted-pair cable connections. Use Figure A-4 for Ethernet/Fast Ethernet straight-through and crossover twisted-pair cable connections.

3	Ethernet port

To determine whether a UTP cable is a crossover cable or a straight-through cable, hold the two RJ-45 connectors next to each other so you can see the colored wires inside the ends, as shown in Figure A-5.

Figure A-5 Identifying a Crossover or Straight-Through Cable

Examine the sequence of colored wires to determine the type of cable, as follows:

•Straight-through—The colored wires are in the same sequence at both ends of the cable.

•Crossover—The first (far left) colored wire at one end of the cable is the third colored wire at the other end of the cable.

You can identify a crossover cable 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 connector (pin 1) should be the same color as the pin on the outside of the right connector (pin 8).

Table A-12 provides information about asynchronous device cabling options.

Gigabit Ethernet Flow Control Information

Flow control is not configurable. The information in this section explains some of the parameters of flow control.

GE port 0/3:

•When the Cisco 7201 GE 0/3 port is set to no negotiation auto, it does not advertise anything in regard to flow control. The Cisco 7201 GE 0/3 port responds to pause frames if the other side makes the request, but will not send pause frames.

•When the Cisco 7201 GE 0/3 port is set to negotiation auto, flow control is enabled, which means the peer accepts symmetrical or asymmetical flow control, and sends pause frames. If the peer does not accept flow control requests, the Cisco 7201 router does not send pause frames. (The Cisco 7201 router always accepts pause frames, whether in fixed mode or auto mode.)

GE ports 0/0, 0/1, and 0/2:

These interfaces function the same as above with the exception that there will never be a pause request transmitted regardless of mode.

Console Port and Auxiliary Port Signals and Pinouts

Note The console cable kit product number is ACS-2500ASYN.

The Cisco 7201 router does not support Data Carrier Detect (DCD).

1 RING is not supported on Cisco-supplied adapters. To use this pin, you must create a customized cable. 2 Pin 7 can be used as a DCD input for connection to a modem. The RJ-45-to-DB-25F adapter maps DCD to this pin when used with a straight-through cable.
