Systems are considered to be components in a rack. Thus, "component" refers to any system as well
as to various peripherals or supporting hardware.
•
Before working on the rack, make sure that the stabilizers are secured to the rack, extended to the
floor, and that the full weight of the rack rests on the floor. Install front and side stabilizers on a single
rack or front stabilizers for joined multiple racks before working on the rack.
•
Always load the rack from the bottom up, and load the heaviest item in the rack first.
•
Make sure that the rack is level and stable before extending a component from the rack.
•
Use caution when pressing the component rail release latches and sliding a component into or out of a
rack; the slide rails can pinch your fingers.
•
After a component is inserted into the rack, carefully extend the rail into a locking position, and then
slide the component into the rack.
•
Do not overload the AC supply branch circuit that provides power to the rack. The total rack load
should not exceed 80 percent of the branch circuit rating.
•
Ensure that proper airflow is provided to components in the rack.
•
Do not step on or stand on any component when servicing other components in a rack.
CAUTION:
Never defeat the ground conductor or operate the
equipment in the absence of a suitably installed ground conductor.
Contact the appropriate electrical inspection authority or an electrician
if you are uncertain that suitable grounding is available.
CAUTION:
The system chassis must be positively grounded to the
rack cabinet frame. Do not attempt to connect power to the system
until grounding cables are connected. A qualified electrical inspector
must inspect completed power and safety ground wiring. An energy
hazard will exist if the safety ground cable is omitted or disconnected.
Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside your system. To prevent static damage, discharge
static electricity from your body before you touch any of the electronic components, such as the
microprocessor. You can do so by periodically touching an unpainted metal surface on the chassis.
You can also take the following steps to prevent damage from electrostatic discharge (ESD):
1.
When unpacking a static-sensitive component from its shipping carton, do not remove the component
from the antistatic packing material until you are ready to install the component in your system. Just
before unwrapping the antistatic packaging, be sure to discharge static electricity from your body.
2.
When transporting a sensitive component, first place it in an antistatic container or packaging.
3.
Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads, workbench
pads and an antistatic grounding strap.
