SAFETY WHEN WORKING WITH ELECTRICITY
| • This device contains no user serviceable parts. This | |
| device can only be repaired by qualified service personnel. | |
WARNING | • Do not open the device when the power cord is connected. | |
For systems without a power switch and without an external | ||
| ||
| power adapter, line voltages are present within the device | |
| when the power cord is connected. | |
| • For devices with an external power adapter, the power | |
| adapter shall be a listed Limited Power Source. The mains | |
| outlet that is utilized to power the device shall be within 10 | |
| feet (3 meters) of the device, shall be easily accessible, and | |
| protected by a circuit breaker in compliance with local regu- | |
| latory requirements. | |
| • For AC powered devices, ensure that the power cable | |
| used meets all applicable standards for the country in | |
| which it is to be installed. | |
| • For AC powered devices which have 3 conductor power | |
| plugs (L1, L2 & GND or Hot, Neutral & Safety/Protective | |
| Ground), the wall outlet (or socket) must have an earth | |
| ground. | |
| • For DC powered devices, ensure that the interconnecting | |
| cables are rated for proper voltage, current, anticipated | |
| temperature, flammability, and mechanical serviceability. | |
| • WAN, LAN & PSTN ports (connections) may have hazard- | |
| ous voltages present regardless of whether the device is | |
| powered ON or OFF. PSTN relates to interfaces such as | |
| telephone lines, FXS, FXO, DSL, xDSL, T1, E1, ISDN, Voice, | |
| etc. These are known as “hazardous network voltages” and | |
| to avoid electric shock use caution when working near | |
| these ports. When disconnecting cables for these ports, | |
| detach the far end connection first. | |
| • Do not work on the device or connect or disconnect | |
| cables during periods of lightning activity. | |
