Follow these steps to connect the PRE to a 10BASE-T Ethernet LAN:
Figure 25
Connecting the 10BASE-T Cable to the Ethernet Port
Step 1
Connect one end of the Ethernet cable to the RJ-45 port on the primary PRE, labeled ETHERNET.
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 LINK LED on the PRE faceplate (next to the ETHERNET port). This LED lights (green) if the PRE is
correctly connected to the 10BASE-T Ethernet LAN.
Connecting to a 100BASE-T Ethernet Network
To connect to a 100BASE-T Ethernet network, you need the following additional equipment (not included):
•
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 not 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.
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).
