Chapter 5– Hot Swap Components
One of the main features of the RamSan-210 is the ability to hot swap many of the
system components. The power supplies, fans and disk drives can all be hot swapped;
meaning that these components can be removed and replacement components reinserted
while the system is running.
5.1 Hot Swapping Power Supplies
The RamSan-210 includes two power supplies. The system only requires one
functioning power supply to run. Texas Memory Systems has taken special care to
enclose the RamSan-210 power supplies in a protective case in order to minimize the
electrical risks for users. It is critical, however, that users follow the following steps
when removing and replacing the power supplies:
Warning:
The power supply modules maintain high voltage levels during normal operation. To
prevent the risk of electrical shock, remove the power cord and wait 15 seconds before
removing a power supply module.
•
Disconnect the power cord from the power supply that needs to be replaced.
•
Wait 15 seconds.
•
Remove the power supply from the RamSan-210 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 supply in the RamSan-210 chassis. Make sure to
insert the power supply squarely and press firmly until the power supply is fully
inserted into the system.
•
The new power supply will begin to operate within a couple of seconds.
Important:
The power supply modules are linked to the batteries. If a power supply module is
removed, the battery that feeds it will not provide power to the system. In other words,
the batteries only work when attached to a functional power supply. Never
simultaneously remove both power supplies while the system is running. The system will
cease operation.
Important:
Failed power supplies should be replaced as soon as possible.
