Network Connection Considerations

Figure 4-10 Six-Port Ethernet Network Processor Module

Token Ring Connections

The dual-port Token Ring network processor module has two standard 9-pin connectors.

(See Figure 4-11.) The single-port Token Ring network processor module has one standard

9-pin connector. (See Figure 4-12.)

Warning The ports labeled “Ethernet,” “10BaseT,” “Token Ring,” “Console,” and “AUX”

are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to

other SELV circuits. Because the BRI circuits are treated like telephone-network voltage,

avoid connecting the SELV circuit to the telephone network voltage (TNV) circuits. (To see

translated versions of this warning, refer to the appendix “Translated Safety Warnings.”)
