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. |
