Cisco Systems Cisco uBR10012 manual Connecting 100Base-T to Ethernet Port

Chapter 3 Installing the Cisco uBR10012 Router

Connecting Network Management Cables

Caution If the Cisco uBR10012 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.

Step 1 Connect one end of the Ethernet cable to the RJ-45 port on the primary PRE, labeled Ethernet (Figure 3-43).

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.

Tip When power is applied to the chassis, check the LNK (Link) LED on the PRE faceplate port next to the Ethernet port. This LED lights (green) if the PRE is correctly connected to the 100Base-T Ethernet LAN.
