1 On November 3, 2003, the 512 MB SDRAM memory option became the default SDRAM memory option for the NSE-100 Processor. The 256 MB SDRAM memory option is still available as a spare, but the 128 MB SDRAM memory option that was once available for the NSE-100 Processor became unavailable for the NSE-100 Processor.

2 OTP = one-time programmable. Although the OTP ROMmon cannot be upgraded, the boot code can be upgraded using the Cisco IOS software. If the boot code is upgraded, the updated boot code is stored in upgradeable boot ROM.

Gigabit Ethernet SFP Port and Cabling Information

For information on the GBICs that are supported on the NSE-100 and the SFPs that are supported on the NSE-150, see the Cisco 7304 Network Services Engine Installation and Configuration Guide.

For information on the SFPs that are supported on the NPE-G100, see the "SFP Port and Cabling Information" section of the Cisco 7304 Network Processing Engine Installation and Configuration Guide.

Gigabit Ethernet RJ-45 Port Pinouts

The Cisco 7304 router has RJ-45 ports for either two or three 10/100/1000 Ethernet/Fast Ethernet/Gigabit Ethernet connections, depending on whether you have an NSE-100 or NPE-G100 installed (the NSE-150 only uses SFPs for Gigabit Ethernet connectivity). 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.


Figure A-1 shows an RJ-45 port and connector. Table A-8Table A-9 lists the pinouts and signals for the RJ-45 port.

NSE-100 and NSE-150 Fast Ethernet RJ-45 Port Pinouts

The Cisco 7304 router NSE-100 has RJ-45 ports for the one Fast Ethernet connection. The RJ-45 ports support IEEE 802.3,( Ethernet), and IEEE 802.3u (Fast Ethernet) interfaces compliant with 10BASET and 100BASETX specifications.

The RJ-45 port supports 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.

Note With reference to the RJ-45 pinout in Table A-9Table A-9, 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).


Use the pinouts shown in Figure A-3 for straight-through and crossover twisted-pair cable connections for your RJ-45 interface cabling requirements.

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.

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.

Console and Auxiliary Port Signals and Pinouts
