Power Supplies

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.

WARNING

REPLACE FAILED POWER MODULES AS SOON AS POSSIBLE.
