Using a tape measure, measure mounting hanger screw location heights on

each side of the rack (see Figure 2-15 Hanger screw layout for UBS Macro

carrier strip assembly on page 2- 40 ). Measure down from the very top of the

rack. Mark the following screw locations:

• 95.25 mm (3.75 inches) for the top of the UBS Macro carrier strip

assembly

P artially insert an M5 x 12 mm screw into each location marked on the rack.

Leave the screw heads extending 7 mm out from the rack surface.

Move the pallet with the unpacked UBS Macro carrier strip assembly and

support near the rack so as to allow movement on both sides of the support

and in front of the rack. Leave the carrier strip assembly on the support.

step 5 through step 7 are for the optional removal of the XMI from the UBS

Macro carrier strip assembly . XMI removal should only be performed if the

UBS Macro carrier strip assembly is too heavy for two people to lift.

The preferred method is to skip the XMI removal steps and use a

suitable device or 4 people to lift the assembly/carrier strips.

The UBS Macro carrier strip assembly with the XMI installed

weighs approximately 60 kg (132.3 lb) and the XMI weighs 23-28

kg (50.7-61.7 lb) depending on the RF band.

If you are skipping the XMI removal steps, go to step 8 . Otherwise, go to

step 5 .

Remove the XMI from the UBS Macro carrier strip assembly . Refer to the

photographs in Figure 2-16 Removing the XMI from the carrier strip assembly

on page 2- 41 . Disconnect all cables from the front of the XMI (see photographs

A and B). Dress these disconnected cables away from the front of the XMI.

Using a T25 TORX driver , remove the four XMI mounting screws; two screws

at each of the top and bottom mounting tabs on the front of the module.
