Replacing a ZS4-4 Memory Riser Card
Use the following procedure to replace a ZS4-4 memory riser card.
-
Shut down the controller using one of the power-off methods described in
Powering Off the Controller.
-
Disconnect the AC power cords from the rear panel of the storage
controller.
![Caution Caution](graphics/caution.gif) | Caution -
Because 3.3 VDC standby power is always present in the system, you
must unplug the power cords before accessing any cold-serviceable
components.
|
-
Extend the controller from the rack as described in Extending the Controller from the Rack.
-
Remove the top cover as described in Removing the Controller Top Cover.
-
To remove the memory riser card, pull the handles upward to disengage the
connector from the motherboard, and carefully lift the memory riser straight
up and out of the controller. The handles act as levers against the
sidewalls to extract the card connector from the connector on the
motherboard.
-
On the replacement memory riser card, ensure that all populated and
unpopulated DIMM slot ejector levers are in the closed and locked
position.
![Caution Caution](graphics/caution.gif) | Caution -
Open DIMM ejector levers can break off during the installation of the
memory riser card. All populated and unpopulated DIMM slot ejector
levers on the memory riser card must be in the fully closed and locked
position before installing the card in the controller.
|
-
In the controller, ensure that the memory riser card ejector levers are in
the closed position.
Note -
The ejector levers are only used to remove a memory riser card and are
not used to install a card.
-
Position the memory riser card over the slot on the motherboard.
The DIMMs on the card must face to the left (when positioned at the front
of the controller).
-
Lower the memory riser card into the controller and set it on the slot on
the motherboard.
-
Ensure that the memory riser card connector is aligned with the
slot.
-
Firmly push down on the metal bracket on top of the card, to seat the card
within the connector on the motherboard.
-
Replace the top cover on the chassis.
-
Return the controller to the normal rack position by pushing the release
tabs on the side of each rail while slowly pushing the storage controller
into the rack.
-
Reconnect all cables to their original ports, referring to the labels
previously added as a guide. For cabling details, see the
Oracle
ZFS Storage Appliance Cabling Guide
.
-
Reconnect the power cords to the power supplies.
-
Verify that standby power is on, indicated by the Power/OK status
indicator flashing on the front panel about two minutes after the power
cords are plugged in.
-
Use a pen or other pointed object to press and release the recessed Power
button on the storage controller front panel.
-
Go to the Maintenance > Hardware screen of the BUI. Click the
right-arrow icon for the controller and then click DIMM to verify that the
status icon
is green for the newly installed memory riser
card.
