If the RamSan power supplies fail, they can be replaced while the power
remains on to the system. There are three ways to detect a bad power
supply. The easiest way is to examine the AC voltage LED. (See Figure 5
– RamSan-500 Power Supply.) If it is illuminated the power supply is
running.
Texas Memory Systems has taken special care to enclose the RamSan-500
power modules in a protective case to minimize the electrical risks for
users; however, it is critical for users to follow the following steps when
removing and replacing the power modules:
Switch the power module off and disconnect the power cord.
Wait 15 seconds.
Remove the power module that needs to be replaced from the
RamSan-500 chassis by pressing the release switch and pulling
squarely on the power supply handle. DO NOT REACH INSIDE THE
PROTECTIVE ENCLOSURE AFTER REMOVING THE POWER
SUPPLY.
Insert the replacement power module in the RamSan-500 chassis.
Make sure the power supply is properly oriented to mate with the
connectors, then insert the power module squarely and press firmly
until the power supply is fully inserted into the system.
Reconnect power to the new power module and switch it on.
The new power module begins to operate when AC is connected and
the power switch is turned on.
