|
Power | Two versions of the HotWire 8600 DSLAM chassis |
| are available: an ac power version and a dc power |
| version. |
| The ac version can be connected to a dc source to |
| provide power redundancy. With the dc version, |
| two separate dc sources may be employed to |
| provide power redundancy. |
| The ac version accepts ac power (100 ± 250V, |
| 50 ± 60 Hz) and converts it to dc power. The |
| maximum current draw is less than 1.75 amps, or |
| 75 watts @ 110 Vac. At maximum configuration |
| with 3 DSL cards, the system will not exceed |
| 85 watts of power dissipation. |
| The HotWire 8600 DSLAM chassis dc version |
| operates from a standard ±48 Vdc power supply |
| (±40.0 to ± 60.0 Vdc). The maximum current draw |
| is 2 amps. At maximum configuration with 3 DSL |
| cards, the system will not exceed 75 watts of |
| power dissipation. |
| Each power version distributes ±48 Vdc power |
| from the power source to individual cards via the |
| backplane. |

|
Grounding | A ground lug is located at the rear of the HotWire |
| 8600 DSLAM at the center. It accepts 14 AWG |
| wire. |

|
Cooling and Air Handling | The internal fan module is installed in the chassis |
| to provide cooling. |
| A |
| cards if a chassis overheats because of fan failure. |
| If the temperature in the chassis reaches 70°C, |
| power to the cards in the chassis is turned off |
| automatically. Power is turned on when the |
| temperature drops below 60°C. |

Operating Environment | Ambient Temperature: 32° to 122° F (0° to 50°C) |
| Relative Humidity: 15% to 90% |
| Shock and vibration sufficient to withstand normal |
