Charging While Connecting to a Computer

When connecting the camera to a computer via the supplied USB cable while Auto (default setting) is selected for the Charge by computer option (A 131) in

the setup menu, the battery inserted into the camera is automatically charged using power supplied by the computer.

See “Before Connecting the Camera” (A80) and “Transferring Pictures from the Camera to a Computer” (A 81) for more information on connecting the camera to a computer.

Charge Lamp

The following chart explains charge lamp status when the camera is connected to a computer.

Not charging.

 

If the charge lamp changes from slow blinking (green) to off

 

while the power-on lamp is lit, charging is complete.

Fast blinking (green)

• Operating temperature range exceeded. Charge the battery

 

indoors with an ambient temperature of 5°C to 35°C (41°F to

 

95°F) before use.

 

• A USB cable is not correctly connected or the battery is faulty.

 

Reconnect the USB cable correctly or replace the battery.

 

• Computer is in sleep mode and does not supply power.

 

Reboot a computer.

 

• The battery cannot be charged as computer’s specifications or

 

settings does not support power supply to the camera.

 

 

B Notes on Charging with Connection to a Computer

• The battery cannot be charged, nor can data be transferred, when the camera is connected to a computer before the camera’s date and time have been set (A 20). If the camera’s clock battery (A 121) has been exhausted, the date and time must be reset before the battery can be charged or images can be transferred with connection to a computer. In this case, use the Charging AC Adapter EH-68P (A 16) to charge the battery and then set the camera’s date and time.

• If the camera is turned off, charging will also stop.

• If a computer enters sleep mode while charging, charging will stop and the camera may be turned off.

• When disconnecting the camera from a computer, turn the camera off and then disconnect the USB cable.

• It may take longer to charge the battery with connection to a computer than with charging using the Charging AC Adapter. Charging time increases when images are transferred while the battery is charging.

• When the camera is connected to a computer, an application installed on the computer, such as Nikon Transfer, may start. If the camera was connected to the computer for the sole purpose of charging the battery, exit the application.

• The camera turns off automatically if there is no communication with the computer for 30 minutes after the battery has finished charging.

• Depending upon computer specifications, settings, and power supply and allocation, it may be

impossible to charge the battery inserted into the camera via computer connection.

One of the primary characteristics of the S640 is its advanced switching capabilities. It operates at Layer 2 and Layer 3, making it suitable for diverse network topologies. The switch is capable of managing a high volume of data traffic efficiently due to its scalability, accommodating growing network needs without compromising performance.

The S640 is equipped with Power over Ethernet (PoE) technology, which simplifies the deployment of connected devices like IP cameras and VoIP phones. This feature not only reduces the need for separate power supplies but also enhances installation flexibility.

Another vital feature of the S640 is its support for Quality of Service (QoS). This functionality ensures that critical applications receive priority over less essential traffic, leading to improved performance for services such as voice and video over the network. QoS management is especially crucial in business environments where it is necessary to maintain operational efficiency and user satisfaction.

Security is paramount in modern networks, and the S640 addresses this with a range of integrated security features. It supports advanced authentication mechanisms such as IEEE 802.1X, ensuring that only authorized devices can access the network. Additionally, features like virtual LAN (VLAN) support help isolate different segments of network traffic, bolstering security and management capabilities.

The S640 also emphasizes energy efficiency, making it an environmentally friendly option for enterprises concerned about their carbon footprint. Nortel has designed this equipment to meet various energy standards, reducing consumption while delivering optimal performance.

In summary, the Nortel Networks S640 stands out in the crowded networking market through its powerful switching capabilities, support for PoE and QoS, robust security features, and commitment to energy efficiency. This combination of characteristics makes it an ideal choice for enterprises looking to upgrade their networking infrastructure to meet contemporary demands.
