Chapter 3 Connecting the Cisco ONS 15530
Connecting the CPU Switch Module
Connecting to a 100BASE-T Ethernet Network
To make a 100BASE-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 UTP cable that meets the following specifications:
–
RJ-45 (male) to RJ-45 (male) straight-through cable.
–
100-ohm category 5 cable no longer than 328 feet (100 meters). (Cisco Systems does not supply
Category 5 UTP cables; these cables are available commercially.)
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.
Note Shielded cables, which are grounded at both ends, are required to be used on the 10/100/1000 Ethernet
port in order to be in compliance with requirement R4-11 in GR-1089-Core for a Central Office
environment. This is not a requirement for customer premise installations.
The port labeled NME on the CPU switch module is configurable for 100-Mbps full-duplex or
half-duplex operation (half-duplex is the default) and supports IEEE 802.3, Ethernet, and IEEE 802.3u
interfaces compliant with 100BASE-T specifications.
