When replacing a fan unit with the Switch turned on, observe the time
limit.
When replacing a fan unit with the Switch on, you must remove and replace the unit
within one minute. If the operation takes longer than one minute, the temperature
inside the Switch will rise and can cause a failure.
When carrying or packing a Switch and its optional modules, wear a
wrist strap to protect against static electricity.
Be sure to wear an antistatic wrist strap. If you handle the Switch without wearing an
antistatic wrist strap, the Switch might be damaged by static electricity.
If you remove an optional module, attach a blank panel.
If you remove an optional module, attach a blank panel. If you continue using the
Switch without attaching a blank panel, the airflow in the Switch cannot be
maintained. As a result, the temperature inside the Switch will rise, possibly
resulting in a failure.
Install a network interface unit with the tray attached.
Install a network interface unit (NIF) with the tray attached to the Switch. If you insert
an NIF without a tray, the NIF cannot fit into the connector on the Switch, and the
Switch or the NIF connector itself might be damaged.
