Chapter 3 Connecting the Cisco ONS 15530

Connecting the CPU Switch Module

The CPU switch module has three RJ-45 ports on the front of the card. This section provides the

procedures for making the following connections:

• Ethernet network management cable connections

• Connecting a terminal to a console port

• Auxiliary modem connection

Keep the following guidelines in mind when connecting external cables to the Cisco ONS 15530:

• Avoid crossing high-power lines with any interface cables.

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

Ethernet Network Management Cable Connections

The CPU switch 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 ONS 15530 to an Ethernet

network.

Note Each CPU switch module must have an Ethernet port connection (typically to the same Ethernet hub) if

you are running a redundant configuration in the chassis.

Connecting to a 10BASE-T Ethernet Network

To make A 10BASE-T Ethernet connection, you need the following additional equipment (not included

with your Cisco ONS 15530):

• 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 cable, 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.
