Overview
The four-port 1-Gb/s copper Ethernet (RJ-45) ports on the four-port 1-Gb/s copper
Ethernet I/O personality module are LAN ports not WAN ports. LAN ports contain safety
extra-low voltage (SELV) circuits, and WAN ports contain telephone-network voltage (TNV)
circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when
connecting cables. To avoid electric shock, do not connect TNV circuits to SELV circuits.
Figure 15 1-Gb/s copper Ethernet I/O personality module (RJ-45) port LEDs
Table 7 describes the SP optional 1-Gb/s copper Ethernet personality module (RJ-45) fault
and port LEDs.
IMPORTANT
The ports shown in Figure 15 are LAN ports. A symbol depicting a telephone handset with
a line through it indicates that you should not connect WAN type RJ-45 telephone
connectors to these ports.
To access the Ethernet ports, connect a Category 5, 5E, or 6 unshielded twisted-pair (UTP)
cable to the RJ-45 connectors on the back of the SP 1-Gb/s copper Ethernet personality
module, as described in
Table 8 on page 27 .
