Installation Overview

Ensure that the host server with the supported HBA is close enough to where you rack the array so that the SAS cables reach.
Install the J4500 array into a compatible rack using orderable slide rails.
Connect the SAS cable(s). See Configuration and Cabling.
Power on the system (host and array) as follows:
1. First, power on the J4500 array by connecting the AC power cords. See Powering On and Off the Array.
2. After one minute, power on the host server.
Note - This sequence is recommended in order to limit the amount of array start up messages going to your server's event log.
Create volumes and install software. Refer to your HBA and operating system software. For more on management options for your array, refer to Chapter 2, Software Overview.

Sun Storage J4500 Array Rack Slide Rails

The J4500 array uses the Sun X4500-J Slide Rail Kit. For information on attaching slide rails and rack-mounting the J4500 array, refer to the Sun X4500-J Slide Rail Installation Guide (820-7238) on the Sun documentation web site:

http://docs.sun.com/app/docs/prod/j4500.array

Compatible Racks

The X4500-J slide rails used with the J4500 array are compatible with a wide range of equipment racks that meet the following standards:

Four-post structure (mounting at both front and rear). Note that two-post racks and two-post racks converted to four-post racks are not compatible.
Rack horizontal opening and unit vertical pitch conforming to ANSI/EIA 310-D-1992 or IEC 60927 standards.
Distance between front and rear mounting planes between 23 and 34 inches (580 mm and 870 mm).
Minimum clearance depth (to front cabinet door) in front of front rack mounting plane: 1.85 inches (47 mm).
Minimum clearance depth (to rear cabinet door) behind front rack mounting plane: 33.5 inches (851 mm) without cable management arm (a cable management arm is not included or supported with this product). The J4500 array fits best in 1000 mm racks. Sun recommends using the Sun Rack 1000-42, Sun Rack 1000-38, Sun Rack II 1042/E, or Sun Rack II 1242/E products with your X4500-J slide rails.
Minimum clearance width between the structural supports and cable troughs: 19inches (483 mm).

Minimum clearance width (not between structural supports and cable troughs) between front and rear mounting planes: 18 inches (456 mm).

Caution - Always load equipment into a rack from the bottom up so that it will not become top-heavy and tip over. Do not attempt to install more than eight J4500 array enclosures in a rack. Deploy your rack's anti-tilt bar to prevent the rack from tipping during equipment installation. For instructions, see the service label on the J4500 array enclosure cover or the label on the rack.

Tools and Staff Required

#2 Phillips screwdriver, 10 inches, magnetic tip recommended
Mechanical lift is highly recommended. The J4500 array can weigh up to 170 pounds (77 kg)
Level (carpenters spirit or bubble)

Staff Required

At least three people are needed to install the J4500 array into the rack:

Two to install the array enclosure and operate the lift
A spotter to ensure rails are engaged correctly

Caution - This assumes a mechanical lift is used. If a mechanical lift is not available, the array enclosure must be depopulated of most components as described below.

Removing Components to Reduce Weight

If a lift is not available, remove the following components to reduce the weight:

Both power supplies
System controller
Hard disk drives in slots 0 to 47 (Sun recommends that you label any hard drives with data before you remove them and make sure they are replaced in the same slot that they are removed from (refer to the service label on the top cover for bay slot numbers)
Do not remove the fan trays

Caution - Once components have been removed, do NOT attempt to lift the chassis at these openings, as the sheet metal might deform. Use the lifting handles on the sides of the chassis.
