sure the service technician uses replacement
parts specified by the manufacturer or that

PCS150R Rack Installation
(also see page 10)
To install the PCS150R in a rack:
• Carefully slide the PCS150R into a standard
19-inch equipment rack.
• When mounting in the rack, make sure to use
the appropriate hardware. ALL FOUR MOUNT-
ING SCREWS MUST BE USED.
• This equipment is not designed to support
other devices. Do NOT stack other equipment
on the top of the PCS150R.
• Rear cabling must be dressed and supported
so that the weight of the cabling is not a strain
on the PCS150R connectors.
• MOUNTING OF THE EQUIPMENT IN THE
RACK SHOULD BE SUCH THAT A HAZARD-
OUS CONDITION IS NOT ACHIEVED DUE TO
UNEVEN MECHANICAL LOADING.
Rack-mount Considerations
A. Elevated Operating Ambient
If installed in a closed or multi-unit rack
assembly, the operating ambient tempera-
ture of the rack environment may be greater
than room ambient. Therefore, consideration
should be given to installing the equipment in
an environment compatible with the maximum
ambient temperature (Tma) specified by the
manufacturer (see Specifications information
in this document).
IMPORTANT SAFETY INSTRUCTIONS
Caution: Refer all servicing to qualified
service personnel.
