Chapter 2: Hardware Installation
15. Airflow considerations: The subsystem requires an airflow
clearance especially at the front and rear. For proper ventilation,
a minimum of 2.5cm (1 inch) is required between the front of the
enclosure and rack cover; a minimum of 10cm (4 inches) is
required between the enclosure and the rear wall of the cabinet.
16. Handle the system modules by the retention screws, ejection
levers, or the module’s metal frame/faceplate only. Avoid
touching the PCB boards or connector pins.
17. Always secure every enclosure module with its retaining screws
or make sure it is held in place by its retention latches or ejection
levers.
18. When working with the subsystem, it is important to use tools
with care. Do not place tools or other items on top of the
enclosure to avoid damaging the outward appearance.
19. If it is necessary to transport the subsystem, remove and
repackage all disk drives separately.
2.3.2
Static-free Installation
Static electricity can damage electronic components. To prevent ESD
damage to any of the components, follow these precautions before
touching or handling them:
Discharge the static electricity accumulated in your body by
wearing an anti-static wristband.
Avoid carpets, plastic, vinyl, and Styrofoam in your work
area.
Handle all components by holding their edges or metal
frames. Avoid touching the exposed circuitry on PCB boards
and connector pins.
2.3.3 Preparation
•
Make sure you are aware of the related positions of each plug-in
module and interface connector.
•
Default configurations: The S12S-R1032 model provides a total
of six (6) 4x SAS ports. The S12S-G1032 model provides three
(3) 4x SAS ports. They are marked as “
CH#
” (host channel) or
“
Exp.
” (expansion port). Use the SAS ports to connect to
application servers or expansion JBODs.
•
Cables must be handled with care and must not be bent over
allowed radius. To prevent emission interference within a rack
