Troubleshooting guide

• If you must stack multiple Switches during transport, use appropriate packaging. Failure
to do so might cause the Switches to become deformed or damaged, resulting in a fire or
electric shock.
Handle the power cable carefully.
• Do not place the power cable near a heat-generating apparatus. The heat could melt the
cable coating, resulting in fire or electric shock.
• When connecting or disconnecting the AC power cable from the outlet, always hold the
plug, not the cable itself. Pulling the cable itself might cause the wires to break.
• When connecting or disconnecting a DC power cable, always hold the connector of the
cable. Pulling the cable itself might cause the wires to break.
When turning off the power, stop the supply of all power to the Switch.
• If power is supplied to an AC model and an AC (PoE) model from an EPU, switch power
cannot be turned off by setting just the power switch of the switch to OFF. To turn off the
power, turn off the Switch and all power supply modules. The label below is attached to a
Switch.
• If the power supply unit for a redundant power model has been made redundant, the Switch
cannot be turned off by setting the power switch of only one power supply unit to OFF. To
turn off the power, set the switches of all power supply units installed on the Switch to
OFF. The label below is attached to a Switch.
