ReadyNAS 3100 Hardware Manual
Replacing a Power Supply
The ReadyNAS 3100 has a 450 watt redundant power supply consisting of two power
modules. Each power supply module has an auto-switching capability, which enables it to
automatically sense and operate at a 100V - 240V input voltage.
If either of the two power supply modules fail, the other module will take the full load and
allow the system to continue operation without interruption. The PWR Fail LED will illuminate
and remain on until the failed unit has been replaced. The power supply units have a
hot-swap capability, meaning you can replace the failed unit without powering down the
system.
You do not need to shut down the system to replace a power supply unit. The backup power
supply module will keep the system up and running while you replace the failed hot-swap
unit. Replace the failed power supply with the same model.
1.
First unplug the AC power cord from the failed power supply module.
2.
Depress the locking tab on the power supply module. Use the handle to pull it straight out
with the rounded handle.
3.
Install a new power supply. Push the new power supply unit into the power bay until you
hear a click. Secure the locking tab on the unit.
4.
Finish by plugging the AC power cord back into the unit.
Replacing the Onboard Battery
This battery must be replaced only with the same or an equivalent type recommended by the
NETGEAR. Dispose of used batteries according to the manufacturer's instructions.
DANGER:
There is a danger of explosion if the onboard battery is installed upside
down, which will reverse its polarities.
To replace the batter, open the system, locate the battery holder and replace the battery,
taking care to be sure to install the new one with the correct side up.
