Safety-11
When removing optional modules, attach blank panels.
Attach a blank panel to a slot where an optional module is not mounted. If you use the Device without
attaching a blank panel, airflow through the Device cannot be maintained. If airflow is not maintained,
the temperature inside the Device rises, resulting in failures. In addition, radio interference generated
by the Device might affect other devices, or radio interference generated by other devices might affect
the Device and cause a malfunction.
Before removing an optional module, loosen the screws completely.
The levers are used to remove basic control units, switch fabric units, packet routing units, or network
interface boards.
If the screws are not loosened completely, the optional module might be damaged when the levers are
opened.
Attach dust covers to the unused interface ports.
If dust covers are provided with the network interface board, use them to cover the unused interface
ports. Dust in the interface port might result in a failure.
Install the power input units to all the power input unit slots.
When using the Device, install the power input units to all the power input unit slots. If you use the
Device without connecting power input units, radio interference generated by the Device might affect
other devices, or radio interference generated by other devices might affect the Device and cause a
malfunction.
When carrying or packing an optional module, handle it carefully.
Do not touch the mounted components, the soldered surface, or the connection terminals when
carrying or packing an optional module such as fan unit, power input unit, power supply unit, basic
control unit, switch fabric unit, packet routing unit, network interface board, memory card, or
transceiver. Also, when storing a module, use an antistatic bag.
Handle the interface cables carefully.
Arrange the cables carefully so that no one will pull on or trip over the cables. Pulling on or tripping
over the cables might result in injury or malfunction of the connected devices.
Do not place anything heavy on the cables. Also, do not place the cables near a heat-generating
apparatus. The heat might damage the cable coating, resulting in a malfunction of the connected
devices.
Check the Device usage environment.
Use the Device in an environment that satisfies the installation requirements. For example, if you place
the Device in direct sunlight or near a heater or other heat-generating device, the temperature inside the
Device will rise, resulting in a malfunction of the Device.
