Power Supply Requirements
To operate your OS-10 equipment safely, follow these requirements:
• Ensure that your power supply meets the site power requirements of the equipment to be installed.
• Check the power at your site to ensure that you are receiving “clean” power (free of spikes and noise). Install
a power conditioner, if necessary.
• Ensure that DC connections are made by an on-site electrician.
• When connecting power to installed equipment, avoid connecting through an extension cord or apower
strip.
Table 5 summarizes the power requirements for the OS-10 system chassis.
Note If you system is shipped with the AC power option, use an AC power
cable appropriate for your country. Check your local electrical codes
and regulatory agencies for power cable requirements.
Note The system uses a universal AC power supply with an autoselection
function for operation with either 110 V (60 Hz) or 220 V (50 Hz).
Distribution Rack Requirements
The OS-10 can be installed in either a 19-inch EIA/TIA or ETSI 300-mm rack.
Note The 19-inch EIA/TIA rack should comply with the specification in
EIA-310-D.
Note The ETSI 300-mm rack should comply with the specification in
ETSI EN 300 119-3 V2.1.0 (2004-05).
