Patton electronic 4940 manual Connecting the PRI

SmartNode 4940 Getting Started Guide 3 • SmartNode installation

Connect the cables in the following order:

The interconnecting cables shall be acceptable for external use

and shall be rated for the proper application with respect to volt-

age, current, anticipated temperature, flammability, and

CAUTION mechanical serviceability.

1.Connect the T1/E1 cables to the PRI T1/E1 ports (see Appendix C on page 47 and Appendix D on page 52).

2.Connect the 10/100/1000Base-T Ethernet (see section “Connecting the 10/100/1000Base-T Ethernet cable” on page 25)

3.Connect the power mains cable (see section “Connecting the power supply” on page 26)

Connecting the PRI

The SmartNode comes with one or four PRI ports. These ports are usually connected to a PBX or switch (local exchange (LE) ). Each PRI T1/E1 port is a RJ-48C receptacle. In most cases, a straight-through RJ-45 can be used to connect the PRI. Each port can be configured as NT (clock master) or TE (clock slave).

For details on the PRI port pin-out and ISDN cables, refer to Appendix C, “Cabling” on page 43 and Appen- dix D, “port pin-outs” on page 47.

Connecting the 10/100/1000Base-T Ethernet cable

The SmartNode 4940 has automatic MDX (auto-crossover) detection and configuration on the Ethernet port. The port can be connected to a host or hub/switch with a straight-through or cross-over wired cable. Connect the LAN network to ETH 0/0.

Note The SmartNode Ethernet port operates in Full Duplex mode only. Do not connect to Half Duplex ports. For best results, use auto-negotiation. Auto negotiation is mandatory when using 1000BaseT (Gigabit) Ethernet.

For details on the Ethernet port pinout and cables, refer to Appendix C, “Cabling” on page 47 and Appendix D, “Port pin-outs”on page 52.
