The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The minimum software requirement for the Cisco 7301 router is Cisco IOS Release 12.2(11)YZ and Release 12.2(13)B.
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 IOS requirements for individual hardware modules or components.
Note Access to this tool is limited to users with Cisco.com login accounts.
To access Software Advisor, click Log In at Cisco.com and go to Technical Support. You can also access the tool by pointing your browser directly to http://www.cisco.com/en/US/customer/products/sw/secursw/ps2136/products_software_advisor_tool_

See Table A-6 for a list of the CWDN SFPs supported on the Cisco 7301 router.
For specification and cabling information, see the following documentation:
•Cisco Small Form-Factor Pluggable Gigabit Interface Converter Data Sheet.
•Cisco 1000BASE-T SFP Data Sheet.
•Cisco CWDM GBIC/SFP Solution Data Sheet.
•Cisco Coarse Wavelength-Divsion Multiplexing SFP Compatability Matrix.
The Cisco 7301 router has RJ-45 ports for the three 10/100/1000 Gigabit Ethernet/Fast Ethernet/Ethernet connections. 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 Systems 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 76

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

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 rollover 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-8 provides information about asynchronous device cabling options.

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. |
The dry relay alarm port operates up to 50V AC/DC maximum and up to 80 mA maximum. Total power dissipation should not exceed 300 milliwatts. The normally closed position will have from 15 to 30 ohms resistance. The open position will be greater than 1 megohm. The alarm condition is the closed position. This port is a switch so that the cable connector can be inserted in either orientation.
