Site Preparation 3-3
Moving Access Requirements
The system is shipped from the factory on one large crate (on a pallet) and several smaller crates or
boxes. The support bay, if included, is shipped on a separate pallet. The large testhead crate may be
too large to move to your system’s destination. If you cannot move it to its final destination, you will
need to unpack the testhead and roll it on its casters (see Chapter 8, Receiving and Moving
Instructions). Other smaller boxes, containing the controller and test development hardware, should
not present access problems.

Dimensions of the Crated System
Dimensions of the Uncrated System
When removed from the crates, the testhead and support bay can be rolled on their casters. This may
make them easier to move.
Table 3-4 lists the dimensions of the uncrated testhead and support bay. Chapter 8, Receiving and
Moving Instructions describes moving the tester on its casters.

System Type Dimension Measurement
Testhead Width 2095 mm (82.5 in)
Depth 1080 mm (42.5 in)
Height 1600 mm (63 in)
Support bay Width 1120 mm (44 in)
Depth 860 mm (34 in)
Height 1600 mm (63 in)
When moving a four-module system that has already been installed, you must move
the testhead and support bay together, subject to the restraint imposed by the cabling
between them. Be very careful not to damage system cables during moving.

Access Requirements
• Ramps
When moved on its casters, the testhead will negotiate ramps with inclines up to 8% before the
leveling feet drag on the floor.
• Hallways and door
As a rough guide, if you have room to move a 4-foot by 8-foot (1.25 m x 2.5 m) sheet of plywood,
parallel to the floor, through hallways and doors, you will be able to move the crated testhead. If
you cannot move the testhead crate all the way, remove it from its crate in a receiving area and
push it on its casters to the destination.

Storage Space Requirements
Setting up your system requires planning for storage. Obviously, you will need a handling and staging
area for the boards you will be testing. Not so obviously, there are other things that you will need to
store, such as the test fixtures.
Backup media storage
The i3070 system is reliable, but no system is safe against data loss due to system disk or computer
failure. Run system backups at regular intervals. Before the system is installed, plan for backup media
storage in the system area. To be safer still, always place a recent backup in a different area or
building.
Fixture storage
You will have a significant investment in your system fixtures. They are precision machines and must
be kept clean and undamaged. Plan safe and dust-free storage near the testhead for your fixtures.
You will receive a Pin Verification Fixture with the first testhead at your site to use to test the MINT
pins of your systems. Be sure to keep the Pin Verification Fixture in your fixture storage area.
Note the following with respect to fixture storage:
• Don’t store fixtures on painted shelves. The bottom of the fixture will scrape small particles of
paint off the shelf which will fall into and contaminate the testhead’s interface pins.
• If possible, cover your fixtures when not in use, especially when the air contains a high level of
particulates.
• Don’t store fixtures on paper-, cardboard-, or carpet-covered surfaces. These materials could
contain corrosive substances that would react with the fixture’s gold-plated personality pins.
• Don’t store fixtures on wooden shelves. Wood splinters can be carried on the bottom of the
fixture to the testhead, thereby contaminating testhead interface pins.
• Don’t stack fixtures on top of one another.
