PCS100R Rack Installation (also see pages 9
and 10)
To install the PCS100R in a rack:
• Carefully slide the PCS100R into a standard
19-inch equipment rack.
• When mounted in the rack, make sure appro-
priate hardware is used. 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 PCS100R.
• Rear cabling must be dressed and supported
so that the weight of the cabling is not a strain
on the PCS100R 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).
B. Reduced Air Flow
Installation of the equipment in a rack should
be such that the amount of air flow required
for safe operation of the equipment is not
compromised. Do NOT stack other equipment
on the top of the PCS100R unit.
IMPORTANT SAFETY INSTRUCTIONS
Caution: Refer all servicing to qualied
service personnel.
