Replacing a Disk Shelf Power Supply
| Caution -
Do not remove a component if you do not have an immediate replacement. The
disk shelf must not be operated without all components in place, including
filler panels. Refer to Disk Shelf Hardware Overview for component locations.
|
Disk shelves are provided with redundant power supplies to prevent loss of
service due to component failure. Each power supply is accompanied by one or
more chassis cooling fans in one customer-replaceable unit (
CRU). Power supplies are hot-swappable, meaning they can be replaced
one at a time without removing power from the disk shelf.
| Caution -
The modules can produce a high-energy hazard and should only be replaced
by instructed individuals with authorized access to the equipment.
|
-
Separate indicator LEDs on the back panel represent the operational state
of power supplies and fans individually; see the rear panel illustration for
details. Failed components are indicated by amber LEDs as well as amber
icons in the administrative BUI. Go to the Maintenance > Hardware section
of the BUI, click the right-arrow icon
at the beginning of the appropriate disk shelf row,
then select PSU or Fan to view details on the respective components. You can
also click the locator icon
to flash the chassis locator LED.
-
Locate the chassis and module containing the failed component.
-
Ensure the power supply on/off switch is in the "O" off position.
-
Disconnect the power cord tie strap from the power cord, and unplug the
power cord from the power supply.
-
Release the lever/ejection arms.
Oracle Storage Drive
Enclosure DE3-24P or DE3-24C:
Push the lever fully downward.
Oracle Storage Drive Enclosure DE2-24P or
DE2-24C:
Grasp the latch and the opposite side of the module, and squeeze together
to release the lever.
Sun Disk Shelf:
Using your thumb and forefinger, unscrew both ejection arm captive screws
until loose and swing the ejection arms out until they are fully
open.
-
Pull the module out of the chassis, being careful not to damage the
connector pins in the back.
-
With the lever/ejection arms fully open (if applicable), slide the new
module into the chassis slot until it contacts the chassis backplane, and
the lever/ejection arms begin to engage. If an Oracle Storage Drive
Enclosure DE3-24, the module clicks in place and the lever engages; then go
to step 9.
Oracle Storage Drive
Enclosure DE3-24P or DE3-24C:
Push on the handle until you hear or feel a
click.
-
Close the lever/ejection arms.
Oracle Storage Drive Enclosure DE2-24P or
DE2-24C:
Push the lever fully closed until you hear or feel a click.
Sun Disk Shelf:
Push the ejection arms fully closed and secure both captive screws to seat
and secure the module in the chassis.
-
Ensure the power supply on/off switch is in the "O" off position.
-
Plug the power cord into the new power supply and attach the power cord
tie strap to the power cord.
-
Place the power supply on/off switch to the "I" on position. The Power/OK
status LED should be a steady green, and all other indicators should be
off.
Note -
After the disk shelf powers on, which could take several minutes,
ensure that the system power indicator on the front of the disk shelf is
lit a steady green, and that each power supply with fan module status
indicator on the rear is list a steady green. If not, power off the disk
shelf and reseat the faulted module. If the module status indicator is
not a steady green after module reinsertion, contact Oracle Customer
Service.
