5. INSTALLATION PRECAUTIONS
• The supplied power supply cord is designed for exclusive use with this unit. Never use it with other
equipment.
• When mounting the unit in an equipment rack, the inside of the rack must be sufficiently ventilated.
To achieve sufficient ventilation, remove all panels on the rear of the rack.
• When mounting the unit in the rack, also mount a Perforated Panel larger than 1U in size*:
(1) at the top and the bottom of the rack, and
(2) above and below every 5 units.
• Robust structure is one of the unit's main features. However, if the strength is particularly needed when
installing the unit in the rack, use a supporting runner for the safety purposes.

mount the unit.
Failure to do so may cause personal injury.
