This section contains procedures to remove and replace a hard drive (HD). Terms used in this section are defined as follows:
HD – A hard drive equipped with rails and a locking mechanism compatible with the HD cage in the Sun Ultra 27 workstation.
HD cage – The metal assembly that holds the system HDs. The rails on the HDs fit into guides on the HD cage. The HD cage is not replaceable, nor is it removed during maintenance procedures.
Storage backplane – The storage backplane is located beneath the HD cage. When correctly inserted into the HD cage, the HD makes contact with the connectors on the storage backplane. The storage backplane also has cables linking it to the power supply and to storage device connectors on the motherboard.
Hard drive assembly – Installed HDs, the HD cage, and the storage backplane.
The Sun Ultra 27 workstation accommodates up to four HDs. If you are not removing an existing hard drive, proceed to To Install a Hard Drive.
Power off the workstation as described in section, To Power Off the Workstation.
Remove the side access panel as described in section, To Remove the Left-Side Access Panel.
Gently lay the system on its right side on a stable, nonslip surface.
Locate the HD to be removed.
Push the plastic latch in the direction of the engraved arrow (away from the metal locking handle) until the HD handle pops out (see Figure 3–5).
Grasp the HD handle and pull straight out to remove the HD from the system.
Set the HD on an antistatic surface.
Choose your next step.
If you removed a hard drive and want to replace it, see the procedure To Install a Hard Drive.
If you removed a hard drive, and are not replacing it at this time, close the workstation as described in the section, Closing the Workstation and Preparing for Operation.
Power off the workstation using procedures in section, To Power Off the Workstation.
Remove the side access panel as described in section, To Remove the Left-Side Access Panel.
Gently lay the system on its right side on a stable, nonslip surface.
If you are replacing a hard drive, see To Remove a Hard Drive.
Remove the new HD from its antistatic packaging.
Handle the HD with care. Dropping or jarring the HD can cause damage.
Push the plastic latch in the direction of the engraved arrow (away from the metal handle) until the HD handle pops out.
Locate the HD assembly and HD cage guides.
You must install a boot drive in HD0, the top slot. Install a second HD in HD1, the second slot. You can install up to four HDs. The third and fourth HD slots are designated as HD2 and HD3, respectively.
Align the HD so the drive is centered with the slot numbering on the HD cage. Be sure that the labeled side of the HD faces upward and the handle hinge is on the left.
Slide the HD into the HD cage until the metal locking handle begins to close.
Press on the plastic parts on either side of the metal locking handle to ensure that the handle engages the HD cage.
Press the metal locking handle closed until it locks the HD into the HD cage.
When correctly installed, the hard drive connector seats firmly into the storage backplane connector.
