Connecting Network Management Cables

Connecting Network Management Cables

The Cisco uBR10012 router has connections to both the internal Ethernet management network and the external data network. The internal Ethernet management network connections are made through an Ethernet port on the front panel of the PRE module.These connections are described in the Ethernet Network Management Cable Connections.

Keep the following guidelines in mind when connecting external cables to the Cisco uBR10012 router:

•To reduce the chance of interference, avoid crossing power lines with any interface cables.

•Verify all cabling limitations (particularly distance) before powering on the system.

Ethernet Network Management Cable Connections

The PRE module provides an Ethernet port to a LAN for a 10Base-T or 100Base-T connection for network management. Use the following procedures to connect the Cisco uBR10012 router to an Ethernet network.

Note Each PRE module must have an Ethernet port connection (typically to the same Ethernet hub) if you are running a redundant configuration in the chassis. However, only the active PRE module has an active Ethernet connection to the network.

Connecting to a 10Base-T Ethernet Network

To make a 10Base-T Ethernet LAN connection, you need the following additional equipment (not included):

•An Ethernet hub (such as a Cisco Micro Hub)

•An Ethernet cable that meets the following specifications:

–RJ-45 (male) to RJ-45 (male) straight-through cable

–100-ohm category 3, 4, or 5, no longer than 328 feet (100 meters)

You can identify a straight-through Ethernet cable either by using a cable tester or by making a visual inspection. To make a visual inspection, hold the two ends of a cable side by side, with the tab for each at the back.

•The wire connected to the left-most pin (pin 1) on one connector should be the same color as the wire connected to the left-most pin on the other connector.

•The same rule applies to pins 2 through 8 on each connector. The color of the wire attached to a pin on one connector should match the color of the wire attached to the corresponding pin on the other connector.

Follow these steps to connect the PRE to a 10Base-T Ethernet LAN.

Step 1 Connect one end of the Ethernet cable to the RJ-45 port on the primary PRE, labeled Ethernet (see Figure 3-42).

Step 2 Run the other end of the Ethernet cable through the square hole at the left front side of the chassis, and connect this end of the cable to any unoccupied port on the Ethernet hub.
