Unpacking Your SCSI Array
This chapter describes the procedure for unpacking the Sun StorEdge 3310 SCSI array package. Topics covered in this chapter are as follows:
Follow these guidelines for unpacking the equipment.
Caution - Always use two people to remove the unit from its container, to avoid personal injury or damage to the equipment during installation. A fully loaded unit weighs approximately 57.2 pounds (26 kilograms).
1. Select a suitable area for unpacking.
2. Store all packing material and boxes for possible equipment returns.
3. Check the Contents Sheet in your product package. See Section 3.2, Checking the Sun StorEdge 3310 SCSI Array Package Contents.
The Contents Sheet summarizes the standard contents for your product.
4. Compare the packing slip and the list of parts with the items you received.
If the list of parts on your packing slip does not match the items you received, or any items appear damaged, immediately notify your carrier agent and the supplier who prepared your shipment.
5. Carefully examine the cables provided in the package.
If any cable appears to be damaged, contact the Technical Service department for an immediate replacement.
6. Check the list of Section 3.4, Customer-Provided Cables.
These are required to complete your installation.
It is important to inspect your Sun StorEdge 3310 SCSI array packages for standard items as well as purchased options before you begin installation. If any parts are missing or damaged, contact your sales representative immediately.

Check that you received all field-replaceable units (FRUs) ordered with your Sun StorEdge 3310 SCSI array. For additional FRUs, consult your sales representative. For instructions on how to install or replace FRUs, review the following manuals located on the product web site:
Caution - You can mix capacity in the same chassis, but not spindle speed revolutions per minute (RPM) on the same SCSI bus. For instance, you can use 36-Gbyte and 73-Gbyte drives with no performance problems if both are 10K RPM drives. Violating this configuration guideline leads to poor performance.
For a list of the FRU part numbers, refer to the Sun StorEdge 3000 Family FRU Installation Guide.
Customers must provide one Ultra 160 SCSI cable per host to connect a host to a RAID array, expansion unit or JBOD; up to two host cables might be needed per array. To obtain qualified cables, consult your Sun sales representative.
Refer to the Sun StorEdge 3000 Family Rack Installation Guide for 2U Arrays for instructions on how to install and prepare a rack or cabinet for mounting your array.
