Replacing an expansion canister

This topic describes how to replace an expansion canister.
Attention: If your system is powered on and performing I/O operations, go to the management GUI
and follow the fix procedures. Performing the replacement actions without the assistance of the fix
procedures can result in loss of data or access to data.
Even though many of these procedures are hot-swappable, these procedures are intended to be used only
when your system is not up and running and performing I/O operations. Unless your system is offline,
go to the management GUI and follow the fix procedures.
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.
Be aware of the following canister LED states:
v If both the power LED is on, do not remove an expansion canister unless directed to do so by a service
procedure.
v If the power LED is flashing or off, it is safe to remove an expansion canister. However, do not remove
an expansion canister unless directed to do so by a service procedure.
Attention: Even if an expansion canister is powered off, it is still possible to lose data. Do not remove
an expansion canister unless directed to do so by a service procedure.
To replace an expansion canister, perform the following steps:
1. Read the safety information to which "Preparing to remove and replace parts" on page 85 refers.
2. Record which SAS cables are plugged into the specific ports of the expansion canister. The cables
must be inserted back into the same ports after the replacement is complete; otherwise, the system
cannot function properly.
3. Disconnect the SAS cables for each canister.
4. Grasp the handle between the thumb and forefinger.
Handles for the expansion canisters are located above and below each other. The upper handle
operates the upper canister. The lower handle operates the lower canister.
