• Condensation might form on the surfaces and the inside of the Switch if it is moved from
a cold location to a warm location. Using the Switch in this condition could result in fire
or electric shock. After moving the Switch between two locations with a large temperature
variation, let the Switch stand a few hours before using it.
Do not touch the inside of the Switch with your hands.
• Do not carelessly put your hands inside the Switch. The frame and components might
cause injury.
Do not step on the Switch, lean against it, or place anything on it.
• Do not step on the Switch or lean against it. Doing so might damage the Switch.
Furthermore, the Switch might fall, or become unbalanced, resulting in injury.
• Do not place anything that weighs more than 5 kg on a switch. Doing so might damage the
Switch. Furthermore, the Switch might fall, or become unbalanced, resulting in injury.
Install a fan unit for the slot of a redundant power model (AX3630S and
AX3640S) with no power supply unit.
Install a fan unit for the slot of a redundant power model (AX3630S and AX3640S) with no
power supply unit. If you use the Switch without installing a fan unit, the following problems
might occur.
• Heat might accumulate inside the Switch and could cause a failure.
• The frame and components might cause injury.
• If foreign objects fall into the Switch, the Switch might no longer work properly.
• The radio waves generated by the Switch might affect another device, or the radio waves
generated by another device might affect the Switch, resulting in a malfunction.
Attach a blank panel to the slot of a redundant power model (AX3830S and
AX3650S) with no power supply unit.
Attach a blank panel to the slot of a redundant power model (AX3830S and AX3650S) with no
power supply unit. If you use the Switch without attaching a blank panel, the following
problems might occur.
• Heat might accumulate inside the Switch and could cause a failure.
• The frame and components might cause injury.
• If foreign objects fall into the Switch, the Switch might no longer work properly.
• The radio waves generated by the Switch might affect another device, or the radio waves
generated by another device might affect the Switch, resulting in a malfunction.
Attach a blank panel to a slot in which a power supply module for an EPU
is not installed.
• Attach a blank panel to a slot in which a power supply module for an EPU is not installed.
If you use the switch without attaching a blank panel, you might be injured by a moving
part. In addition, if foreign objects fall into the Switch, the Switch might no longer work
properly.
Cleaning
• Remove dust on and around the Switch regularly. In addition to causing the Switch to stop,
accumulated dust could result in a fire or electric shock.
