1TECHNICAL SUMMARY
1.1 BRIEF DESCRIPTION
1.1.1 OVERVIEW
The OSD350B is a 19" 3RU (133mm) high rack mounting chassis, which accepts two OSD921 power
supply modules plus from one to twelve OSD standard card format plug-in modules. The system
employs a 9-pin female D connector at each position for card powering and for the OSD Network
Management slot addressing. The plug-in power supply is capable of providing power for almost any
combination of plug-in cards but it is suggested that the user confirm that his projected combination of
cards can be supported by the OSD921 power supply unit. Individual product data sheets provide the
Chassis Current Consumption (CCC) for each plug-in card: the total of these must be less than the
rating of the OSD921 Power Supply Unit, ie 6 Amp total
1.1.2 APPLICATIONS
▲ Use where OSD fiber optic cards required
1.1.3 FEATURES AND BENEFITS
▲ Compact 3RU high, 19” rack mounting unit
▲ Holds up to 12 5T-width OSD standard-sized cards
▲ Requires one OSD921 power supply unit
▲ Supports any combination of OSD cards
▲ Power supply fail alarm output

3INSTALLATION AND OPERATION
3.1 OSD921 POWER SUPPLY OPERATION
The OSD350B can use up to two OSD921 power supply units.
A front panel mounted LED indicator on the OSD921 illuminates when the power supply unit is
switched on. Front panel test points are available on the OSD921 for monitoring the 12VDC output
of the supply. Note that the test point outputs are current limited and cannot be used as a power
source.
The OSD921 supply has a built-in cooling fan.
The cooling fan operates only when high temperatures are experienced on the power supply whilst
under heavy load and/or high ambient temperatures.
The fan may not continuously operate and under low load or low ambient temperatures it may not
operate at all.
The Temperature Alarm LED on the front panel of the OSD921 is green during normal operation
and will be red when the operating temperature exceeds the normal operating limits of the supply.
Do not continue to operate the power supply when the Temperature Alarm LED is red and take steps
to rectify the cause of the excessive high temperature indication.
3.2 IMPORTANT INSTALLATION REQUIREMENTS
It is important to provide a cool operating environment as well as to provide adequate ventilation.
The OSD350B chassis must be separated by at least a 1RU (about 44mm) gap above and below
the unit to provide ventilation.
The ventilation holes of the chassis must never be covered by any objects.
3.3 BACK PLANE OUTPUTS
The OSD350B is merely a mechanical chassis, so electrical specifications are not given, other than
the pin outs for the 9-pin D female connector of the back plane.

3.4 ALARM OUTPUTS
There are alarm outputs available on the rear panel via a 9-pin D female connector.
The alarm outputs are normally open circuit when each of the power supplies is operational.
If there is a power supply failure or excessive operating temperature, the alarm output is connected to
ground via a relay.
The pin out of the 9-pin D female connector is as follows:
Pin 3 PSU 1 Alarm Output
Pin 4 PSU 2 Alarm Output
Pin 7 Ground Return
All other pins are not used.
NOTE: The alarm indication is only available if the OSD921 power supply is installed.
