Figure 22: Placement of Gateway in Rack
Consider the following when deciding where and how to mount the rails and rail slides:
The distance between the rack and the door can be as little as 1.57” (4 cm) on one side of the rack
and as much as 7”(18 cm) on the other side of the rack. Keep in mind that there can be as many
as36 cables connected to the gateway.
• Do you want the connector side recessed in the rack to allow for a larger cable bending
radius? It is possible to recess the connector side by 2” (5cm) by optional placement of
the gateway rails. See Figure 23,“Mounting Options”.
• Will the connector side be recessed past other equipment in the rack and will this be
problematic?
• The installation kit allows for a 2” (5cm) recess of the gateway past the vertical support.
• Make sure the gateway air flow is compatible with your installation selection.
