Chapter 3 Installing the Cisco 10008 Router
Connecting Network Management and Signal System Cables
• 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.
Caution If the Cisco 10008 router is used in an environment in which lightning-induced transients are likely to
couple to the signal lines, use of shielded interconnection cables for the 100BASE-T ports is highly
recommended. In addition, use of shielded interconnection cables for the 100BASE-T ports is required
to meet Telcordia (formerly Bellcore) GR1089 CORE Section 4.5.9 and ETSI Section 5.2.2.2
(intrabuilding lightning surge).
The RJ-45 port on the PRE 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.
Follow these steps to connect the PRE to a 100BASE-T Ethernet LAN:
Figure 3-34 Connecting 100BASE-T to Ethernet Port
Step 1 Connect one end of the Ethernet cable to the RJ-45 port on the primary PRE, labeled ETH (Figure 3-34).
Step 2 Run the cable up and through the cable management bracket and connect the other end of the Ethernet
cable to any unoccupied port on the Ethernet hub.
Step 3 Check the LNK (Link) LED on the PRE (next to the ETH port).
This LED lights (green) if the PRE is correctly connected to the 10BASE-T Ethernet LAN.
