|Sun ZFS Storage 7120, 7320, and 7420 Appliance Installation Guide|
Observe the following cautions when installing the Oracle Storage Drive Enclosure DE2-24P into a rack using the supplied rail kit. Note that if your rail kit shipped with installation instructions, use those instructions instead.
Always load equipment into a rack from the bottom up so that it will not become top-heavy and tip over. Deploy the anti-tip bar to prevent the rack from tipping during equipment installation.
Ensure that the temperature in the rack does not exceed the controller's maximum ambient rated temperatures. Consider the total airflow requirements of all equipment installed in the rack to ensure that the equipment is operated within its specified temperature range.
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.
Do not lift the disk shelf by the handles on the power supply with fan modules; they are not designed to take the weight.
Refer to the following section for an overview of your disk shelf.
Disk Shelf Overview - view component diagrams and specifications
To install the shelf, you need the following tools:
Phillips head No. 2 screwdriver that is a minimum of 4 inches long.
T20 Torx driver if using a threaded cabinet.
A mechanical lift is highly recommended because the chassis can weigh approximately 51 lbs (23 kg). At least three people are required: two to install the shelf and one spotter to engage the rails.
Use one of the following racks for the disk shelf:
Sun Rack II 1042/1242 cabinet
Any 19-inch wide, 4-post, EIA-compatible rack or cabinet with a front-to-back depth between vertical cabinet rails of 61 cm to 91 cm (24 in. to 36 in.). The cabinet can have threaded or unthreaded cabinet rails. Threaded cabinets must be M6 or 10-32 cabinets. Cabinets must be able to support the weight of all equipment contained within them.
Position the rack where the shelf is to be installed adjacent to the rack where the controller is installed, if separate. Stabilize the cabinet and lock the casters. To facilitate access, remove doors from cabinets.
For an unthreaded universal 19-inch or Sun Rack II cabinet:
a) Position the front rail location pegs fully inside the appropriate holes in the front of the rack. The rail flange must be inside of the cabinet flange, and the rail label facing the inside of the cabinet.
b) Insert and loosely tighten one screw through the front of the rack and into the top hole in the rails.
c) Adjust the rail lengths to fit, and position the rear rail location pegs in the corresponding rear rack holes.
d) Insert and loosely tighten one screw through the back of the rack and into the back of the rails.
For a threaded universal 19-inch cabinet:
a) Use the T20 Torx driver to remove the rail location pegs from the front and rear of the rails.
b) Use the supplied wrench to insert two pins into each end of the rails, in the same location where the location pegs were removed.
c) Position the front of the rails inside the cabinet, with the rail flange inside of the cabinet flange, and the rail label facing the inside of the cabinet. The pins should be fully located within the rack holes.
d) Insert and loosely tighten one screw through the front of the rack and into the top hole in the rails.
e) Adjust the rail lengths to fit, and locate the rear pins inside the corresponding rear rack holes.
f) Insert and loosely tighten one screw through the back of the rack and into the back of the rails.
Ensure you have met the following electrical safety measures before applying power to the disk shelf:
Provide a suitable power source with electrical overload protection to meet the power supply input voltage range of 100-240 VAC, 50-60 Hz. The disk shelves are compatible with 100-120 VAC or 200-240 VAC sources. The power source must not be overloaded by the total number of disk shelves in the cabinet. At full load, each DE2-24 draws 1,140W, and each Sun Disk Shelf draws 912W.
The power source must provide a reliable earth connection for each disk shelf and the cabinet.
Ensure that the power source is easily accessible because the power cord is the main disconnect device for the disk shelf.
Plug a power cord into each power supply with fan module.
Plug the other end of the power cords into the external power source for the cabinet.Note: To guarantee redundancy, power cords must be connected to two separate and independent power sources.
Apply power to the external power source.
Place the power supply on/off switches to the "I" on position.
Turn on the cabinet circuit breakers, if applicable.
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 lit a steady green. If not, power off the disk shelf as described in the next section and reseat the faulted module. If the module status indicator is not a steady green after module reinsertion, contact Oracle Customer Service.
Perform the software setup tasks as described in the storage controller installation guide.
Most disk shelf components are hot-swappable; you do not need to remove power when replacing them. 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.
Powering off or removing all SAS chains from a disk shelf will cause the controller(s) to panic to prevent data loss, unless the shelf is part of an NSPF (no single point of failure) data pool. To avoid this, shut down the controller(s) before decommissioning the shelf. For details on NSPF profiles, see Profile Configuration.
Stop all input and output to and from the disk shelf.
Wait approximately two minutes until all disk activity indicators have stopped flashing.
Place the power supply on/off switches to the "O" off position.
Disconnect the power cords from the external power source for the cabinet.Note: All power cords must be disconnected to completely remove power from the disk shelf.
