You can replace a faulty 2U expansion canister with a new one received from FRU
stock.
Before you begin
Attention: Although many 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 of data or loss of access to data.
Do not remove an expansion canister unless you are directed to do so by a service
procedure.
In the management GUI, select Monitoring > System.
On the System -- Overview page, select the directional arrow next to
the expansion enclosure.
On the Enclosure Details page, select Enclosure Actions > Identify to set the canister fault LED flashing.
Record which SAS cables are plugged into the specific ports of the expansion enclosure. To
view SAS connections for the enclosures, return to the System --
Overview page and select SAS Chain View to display the SAS
ports and connections between the enclosures. Click a port to view details for the SAS ports.
The cables must be inserted back into the same ports after the replacement is complete;
otherwise, the system cannot function properly.
Be careful when you are replacing the hardware components that are
located in the back of the system. Do not inadvertently disturb or remove any cables that
you are not instructed to remove.
Disconnect the SAS cables from the canister.
Open the two release levers, as shown in Figure 1.
The canister moves out of the slot approximately 0.6 cm (0.25 inches).
Slide the canister out of the slot.
Replace an expansion canister
Open the release levers of the replacement canister.
Push the replacement canister into the slot until it stops.
Finish inserting the canister by closing both release levers so that both orange clasps
snap into place.
The canister is correctly installed when the rear face of the canister is flush with the
rear edge of the enclosure.
If the enclosure is powered on and the canister is correctly installed, the canister
starts automatically.
Reattach each SAS cable into the port from which it was removed in step 6.
Ensure that the SAS cable connectors are inserted with the pull tab to the bottom of the
connector; then, gently push the connector in until a slight click is felt or heard.
Verify that the connector is fully inserted by gently pulling on it (not on the
tab).
If the enclosure is powered on and the SAS connector is correctly inserted into
the port, the green SAS link LED above the port lights up.
