Infoblox offers an adjustable four-post rail kit providing 600mm to 900mm depth adjustment. It is designed to allow one person to perform the physical installation of the rack kit and the appliance.
The adjustable rail kit is designed for tight vertical spaces on the interior of a four-post rack, allowing for appliance installation in restricted rack spaces, including 2U or even 1U of available rack space.
The adjustable rail kit includes the following items for installation:
- Eight (8) Flat-head beveled 8/32" screws that attach rail pieces to the appliance chassis
- Eight (8) Phillips-head 10/32" screws for affixing the rack rails to the four-post rack
The technician must provide four attachable cage nuts for adapting the square mounting holes on the rear posts of the four-post rack to accept the 10/32" screws.
To install the adjustable rail kit, do the following:
- Install the cage nuts in the rear rack posts in the desired location, as indicated in Figure 10.
