Connecting Cables Chapter 3 Installing the Cisco VG224 Voice Gateway Connecting Cables For cables not included with your Cisco VG224 voice gateway, pinout information is in Appendix A, "Cable Specifications and Information." Cisco VG224 voice gateway ports are color-coded for identification. Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001 Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than: 120 VAC, 15A (240 VAC, 10A international) Statement 1005 Warning To prevent accidental discharge in the event of a power line cross, route on-premise wiring away from power cables and off-premise wiring, or use a grounded shield to separate the on-premise wiring from the power cables and off-premise wiring. A power line cross is an event, such as a lightning strike, that causes a power surge. Off-premise wiring is designed to withstand power line crosses. On-premise wiring is protected from power line crosses by a device that provides overcurrent and overvoltage protection. Nevertheless, if the on-premise wiring is in close proximity to, or not shielded from, the off-premise wiring or power cables during a lightning strike or power surge, the on-premise wiring can carry a dangerous discharge to the attached interface, equipment, and nearby personnel. Statement 338 Table 3-2 shows the results of the NEBS Type 1/3 power cross tests (tip/ring to ground) performed on the Cisco VG224 voice gateway FXS ports. Table 3-2 Results of the NEBS Power Cross Tests on FXS Ports NEBS Tests 50 V/0.33 A; 15 minutes 100 V/0.17 A; 15 minutes 200 V/1.00 A; 1-second pulses, 60 repetitions Results Pass Pass Pass Note The installation must comply with all applicable codes. 3-14 Cisco VG224 Voice Gateway Hardware Installation Guide OL-5006-04
