Chapter 3 Installing a Cisco 7200 VXR Router Connecting I/O Controller, NPE-G1, or NPE-G2 Cables Note 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 WS-G5486 or GBIC-LX/LH is compliant with the IEEE 802.3z standard for 1000BASELX. A mode-conditioning patch cord can be used with the WS-G5486= or GBIC-LX/LH= to allow reliable laser transmission between the single-mode laser source on the GBIC and a multimode fiber-optic cable. Note We strongly recommend cleaning optical fiber connections before attaching cables to equipment. See the "Fiber-Optic Cleaning Information" section on page 5-10 for information. Gigabit Ethernet RJ-45 Connections on the NPE-G1 and NPE-G2 The NPE-G1 and NPE-G2 RJ-45 ports support 10BASET, 100BASETX, and 1000BASET and 1000BASEX protocols and the ports are compliant with IEEE 802.3, IEEE 802.3u, and IEEE 802.1q standards. The RJ-45 ports support standard straight-through and crossover Category 5 UTP cables with RJ-45 connectors. (See Figure 3-23 and Figure 3-24.) Cisco Systems does not supply Category 5 UTP cables; these cables are available commercially. Figure 3-20 shows an RJ-45 port and connector. Table 3-10 lists the pinouts and signals for the RJ-45 port. Table 3-10 NPE-G1 and NPE-G2 RJ-45 Port Pinouts Pin 10/100 Signal 1 Tx Data+1 2 Tx Data- 3 Rx Data+2 4 N/C 5 N/C 6 Rx Data- 7 N/C 8 N/C 1.

Installing a Cisco 7200 VXR Router

Connecting I/O Controller, NPE-G1, or NPE-G2 Cables

Note

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 WS-G5486 or GBIC-LX/LH is compliant with the IEEE

802.3z standard for 1000BASELX.

A mode-conditioning patch cord can be used with the WS-G5486= or GBIC-LX/LH= to allow reliable

laser transmission between the single-mode laser source on the GBIC and a multimode fiber-optic cable.

Note

We strongly recommend cleaning optical fiber connections before attaching cables to equipment. See the

“Fiber-Optic Cleaning Information” section on page 5-10

for information.

Gigabit Ethernet RJ-45 Connections on the NPE-G1 and NPE-G2

The NPE-G1 and NPE-G2 RJ-45 ports support 10BASET, 100BASETX, and 1000BASET and

1000BASEX protocols and the ports are compliant with IEEE 802.3, IEEE 802.3u, and IEEE 802.1q

standards.

The RJ-45 ports support standard straight-through and crossover Category 5 UTP cables with RJ-45

connectors. (See

Figure 3-23

and

Figure 3-24

.) Cisco Systems does not supply Category 5 UTP cables;

these cables are available commercially.

Figure 3-20

shows an RJ-45 port and connector.

Table 3-10

lists the pinouts and signals for the RJ-45

port.

Note

With reference to the RJ-45 pinouts in

Table 3-10

, 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 3-23

and

Figure 3-24

for straight-through and crossover twisted-pair cable connections.
