■ For carrying or packaging the device and optional component, use an antistatic wrist
strap.
• Use an antistatic wrist strap. If you handle the device without the antistatic wrist strap, the device can be
damaged by the static electricity.
■ After removing an optional component, be sure to attach a blank panel.
• After removing an optional component, be sure to attach a blank panel. Using the device without the blank
panel attached, the air flow in the device cannot be maintained. In such a case, the temperature rise inside the
device may cause a failure.
■ Attach an option component with care.
• Follow the following procedures to attach an option component. Otherwise, a problem may occur on the device.
1. Open the levers as the figure below.
2. With the levers in hands, push the component slowly into the device, to the point where the levers touch the device.
3. Use the levers to insert the component all the way. Move the levers slowly (taking more than one second) but not forcedly.
■ Before removing an optional component, loosen the screws completely.
• Use levers to remove the basic switching unit or network interface module. If screws are not completely
loosened, the optional component may be damaged when the levers are pressed down.
■ When carrying or packing an optional component, take care for handling.
• Take care not to handle the connector when carrying or packing optional components such as the basic
switching unit, network interface module, memory card, transceiver, and power supply. They must be stored in
antistatic bags when they are not in use.
■ Do not install the device in any place possibly reaching a high temperature.
• Be careful that the parts may be damaged if left in a place exposed to direct sunlight or close to a heating
apparatus.
