Choosing a Setup Location

- Leave enough clearance in front of the rack to enable you to open the front
door completely (~25 inches).
- Leave approximately 30 inches of clearance in the back of the rack to allow
for suffi cient airfl ow and ease in servicing.
-This product is for installation only in a Restricted Access Location (dedicated
equipment rooms, service closets and the like).

Rack Precautions

- Ensure that the leveling jacks on the bottom of the rack are fully extended to the
fl oor with the full weight of the rack resting on them.
- In single rack installation, stabilizers should be attached to the rack.
- In multiple rack installations, the racks should be coupled together.
- Always make sure the rack is stable before extending a component from the
rack.
- You should extend only one component at a time - extending two or more simul-
taneously may cause the rack to become unstable.

Server Precautions

- Review the electrical and general safety precautions in Chapter 4.
- Determine the placement of each component in the rack before you install the
rails.
-
Install the heaviest server components on the bottom of the rack fi rst, and then
work up.
- Use a regulating uninterruptible power supply (UPS) to protect the server from
power surges, voltage spikes and to keep your system operating in case of a power
failure.
-
Allow the hot plug SATA/SCSI drives and power supply units to cool before touch-
ing them.
-
Always keep the rack's front door and all panels and components on the servers
closed when not servicing to maintain proper cooling.
