Guidelines for Rack Mount Installation
The installation site must be within reach of the network cabling and meet the requirements listed
below:
•
Shelf placement must be close enough to connect the 6.6-foot (2-meter) AC power cords from the
power supplies to the AC power source.
•
One or two three-pronged power receptacles capable of delivering the current and voltage specified
in STK-RPS-150PS and RPS Shelves Technical Specifications on page 387. One or two AC outlets on
independently-fused circuits must be within 6 feet (1.8 meters) from the installation site. If there is an
AC power source failure, this will prevent the powering down of redundant power supplies due to a
single source power failure.
•
Power cords and type of outlet are dependent on the country. In the United States, one power cord
with an NEMA 5-15P plug is provided with each STK-RPS-150PS.
•
An ambient temperature of between 32°F (0°C) and 122°F (50°C) must be maintained at the
installation site with fluctuations of less than 18°F (10°C) per hour.
Caution
To ensure proper ventilation and prevent overheating, leave a minimum clearance space of
3 inches (7.6 cm) at the front and rear of the unit.
Warning
Before installing the shelf into a rack, ensure that the rack can support the device(s)
without compromising the stability of the rack. Otherwise, personal injury and/or
equipment damage may result.
Rack Mounting the RPS Shelf
To install the RPS shelf into a 19-inch (48.3 cm) rack:
1 Position the RPS shelf between the vertical rails and align the mounting holes in the RPS shelf
brackets with those in the rack frame.
2 Fasten the RPS shelf securely to the rails using the customer-supplied mounting screws (four for the
STK-RPS-150CH2, ten for the STK-RPS-150CH8).
