Determine which rail kit to use
The 3900 platform comes with two types of rack mounting kits: stationary front-mounting and sliding rail-mounting.
An advantage of installing the sliding rail-mounting kit is that you can then slide the unit in and out of the rack as needed.
The tasks you need to perform to install the platform differ, depending on the type of rack mount you decide to use or
which type of cabinet unit you are installing into (single two-post cabinet or four-post cabinet).
General recommendations for rack mounting
Although not required, a 1U space between units makes it easier for you to remove the unit from the rack if that the unit
requires service. A 1U space between units also provides additional cable routing options.
We recommend 100 mm spacing from the front panel of the unit to the rack front or rack door. This provides enough
room for you to route the cables without excessive bending or insulation damage.
A shelf or similar device is required to support the unit if only one person is installing the unit.
Caution: To prevent personal injury or damage to the unit, we recommend that at least two people perform the
installation.
Caution: This product is sensitive to electrostatic discharge (ESD). We recommend that you use proper ESD
grounding procedures and equipment when you install or maintain the unit.
Caution: Do not power on the platform until the management serial console or the management network is
connected to the unit.

Installing using a front-mounting kit
Before you install this platform, review the environmental guidelines to make sure that you are installing and using the
platform in the appropriate environment.
This platform includes front-mounting brackets, which you can use to attach the unit directly to the rack.
1. Align the bracket's keyhole slots with the PEM fasteners on the side of the unit.
2. Slide the bracket toward the back of the unit to lock the bracket into place.
