Installing an Expansion Hub in a Wall-Mounted Rack
Considerations:
• The rack and the Expansion Hub are both 305 mm (12 in.) deep. The rack mount-
ing brackets on the Expansion Hub must be moved from the front position to allow
for the 76 mm (3 in.) rear clearance 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 the following figure for bracket placement.
4. Attach the Expansion Hub to the rack.
Installing an Optional Cable Manager in the Rack
• Using the screws provided, fasten the cable manager to the rack, immediately
above or below the Expansion Hub.
Right Rack Mounting Bracket as
installed from the factory.
Left Rack Mounting Bracket installed on
the right side of the hub.
