Fusion Installation Procedures

7-20 InterReach Fusion Installation, Operation, and Reference Manual

CONFIDENTIAL D-620TBD-0-20 Rev A

Installing an Expansion Hub Using the 12” Wall-Mounted Rack

Considerations:

• The rack (PN4712) is a 305 mm (12 in.) deep. The Expansion Hub is 381 mm (15

in.) deep. You must move the rack mounting brackets on the Expansion Hub to the

center mounting position to allow for the 76 mm (3 in.) rear clearance that is

required.

• The maximum weight the rack can hold is 22.5 kg (50 lbs).

To install the hub in a wall-mounted rack:

1. Attach the equipment rack to the wall using the screws that are provided.

The rack must be positioned so that the Expansion Hub will be in a horizontal

position when it is installed.

2. Remove both of the rack mounting brackets from the hub.

3. Reattach each of the rack mounting brackets to the opposite side of the hub from

which it came.

Refer to Figure 7-4 for bracket placement.

Figure 7-4 Mounting Bracket Installation

4. Attach the Expansion Hub to the rack.
