JMR electronic G5312 6. Power Supply Operation

This chapter covers all operations of the power supplies. For operation, the AC
cord (included) must be connected to the AC Inlet on each supply, and the power
supply must be switched ON. The 'OK LED' will light to indicate the power
supply is functioning properly. If the power supply experiences a problem and
cannot operate within its normal specifications, the Fault LED will light and the
power supply will shut itself off.
The power supplies also have their own fan included to maintain proper cooling
within each supply and also provide some additional, but minimal airflow through
the rest of the enclosure.
Power Supply Removal/Insertion
Follow the following steps to either remove a power supply in a 10/15-bay unit.
1. Unfasten the power supply thumbscrew by turning
counterclockwise. A Phillips head screwdriver
may be used if the thumbscrew is too tight to turn
by hand.
2. Remove by pulling out on the handle.
Reverse the steps to reinstall the power supply.
