This topic describes how to replace a node canister.
Attention: Even though many of these components are hot-swappable,
they are intended to be used only when your system is not active (no
I/O operations). If your system is powered on and processing I/O operations,
go to the management GUI and follow the fix procedures. Initiating
the replacement actions without the assistance of the fix procedures can result in loss

Be careful when
you are replacing the hardware components that are located in the
back of the system that you do not inadvertently disturb or remove
any cables that you are not instructed to remove.
Attention: Do not replace one type of node canister
with another type. For example, do not replace a model 2076-112 node
canister with a model 2076-312 node canister.

- If the power LED is flashing or off, it is safe to remove a node
canister. However, do not remove a node canister unless directed to
do so by a service procedure.
Attention: Even if a node canister is powered
off, it is still possible to lose data. Do not remove a node canister
unless directed to do so by a service procedure.
