Chapter 2: System Installation
•
In single rack installations, stabilizers should be attached to the rack. In multiple rack in-
stallations, the racks should be coupled together.
•
Always make sure the rack is stable before extending a server or other component from
the rack.
•
You should extend only one server or 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
•
Determine the placement of each component in the rack
before
you install the rails.
•
Install the heaviest server components at the bottom of the rack first and then work your
way up.
•
Use a regulating uninterruptible power supply (UPS) to protect the server from power
surges and voltage spikes and to keep your system operating in case of a power failure.
•
Allow any drives and power supply modules to cool before touching them.
•
When not servicing, always keep the front door of the rack and all covers/panels on the
servers closed to maintain proper cooling.
Workstation Precautions
•
Review the electrical and general safety precautions in
•
Use a regulating uninterruptible power supply (UPS) to protect the workstation from power
surges, voltage spikes and to keep your system operating in case of a power failure.
•
Allow the power supply units and hot-swap SATA drives to cool before touching them.
•
To maintain proper cooling, always keep all chassis panels closed and all SATA carriers
installed when not being serviced.
Rack Mounting Considerations
Ambient Operating Temperature
If installed in a closed or multi-unit rack assembly, the ambient operating temperature of the
rack environment may be higher than the room's ambient temperature. Therefore, make sure
