PRECAUTIONS
Failure to comply with these general safety precautions and with the specific
precautions described elsewhere in this manual violates the safety standards of the
design, manufacture, and intended use of the device. Olson Technology Inc. assumes
no liability for the customer’s failure to comply with these precautions.
CAUTION: Ensure that the voltage visible through the Line Voltage Indicator window on
the AC power entry port of the power supply module corresponds to the range in the
specifications (85 to 264 V ).
CAUTION: Do not operate the chassis or power supply outside of their maximum
ratings. Doing so may result in unsatisfactory performance, unit failure, shortened unit
life span, or a safety hazard.
CAUTION: Do not attempt to modify or service any part of this chassis not specifically
referred to as replaceable in this manual. Doing so voids the warranty. Return the
chassis to Olson Technology Inc. for service and repair.
CAUTION: No chassis should be operated in an ambient environment above 50ºC
(122ºF).
CAUTION: Do not restrict airflow in front or back of the chassis. The OTOHP-PS power
supply module should be operated in an ambient environment between 0 and 50ºC (32
and 122ºF) for a continuous output of 200 watts.
AC
CAUTION: Store the chassis and power supply module away from corrosive materials,
at a temperature between -40 and +70ºC (-40 to +158ºF), and with no more than 85%
humidity, non-condensing.
INTRODUCTION
The Olson Technology, Inc. Model OTOHP-CH is a standard 19-inch width, 3RU high
chassis that is the heart of Olson Technology’s OHP (Optical Headend Platform) system.
The chassis is 3RU high and has seventeen(17) slots to accommodate all module
types. The chassis will hold up to fifteen (15) modules and one (1) OTOHP-PS power
supply or thirteen (13) modules and two redundant power supplies. A backplane
interface provides inter-module communication and power distribution. OTOHP-BP
blank panels can be ordered to cover the slots not being used by a module.
The OTOHP-PS power supply module provides stable powering for all modules in the
chassis. The auto-recovery short circuit protection function of the power supply
improves the reliability of the platform. On the front panel, LED’s indicate the module
status and health and DC voltage output status. OTOHP-PS also provides a +24VDC
test point voltage testing for output.
