Safety-11
Attach a blank panel to a slot in which a power supply module for an EPU is not
installed.
 Be sure to attach a blank panel to any slots for which a power supply module for an
EPU is not installed. If you use the Switch without attaching the 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 possibly causing the
Switch to stop, accumulated dust might result in fire or electric shock.
