Positive Pressurization and Ventilation - Hot Aisle Containment
System (HACS)
Adequate airflow prevents equipment damage.
When installing the SL150 in an HACS environment, the system must maintain
adequate air flow from the cold to hot aisle. Ensure that there is no turbulent air
directed at the installed equipment which may reduce the cooling capability of the
cold aisle supply air. The HACS pressure differential should have neutral to negative
pressure in the hot aisle. To achieve this, you may need to install rack doors on
contributing or affected racks. If this is ineffective to reduce air impediment, you may
need to install a supplemental air removal unit to boost airflow through the equipment.
Electrostatic Discharge
A discharge of static electricity might damage static-sensitive devices which may
reduce the life expectancy of the product.
Avoid electrostatic discharge when handing parts. Electrostatic discharge can damage
components. Follow the guidelines below to prevent electrostatic discharge.
Electrostatic Discharge Prevention
•
Avoid hand contact by transporting and storing products in static-safe containers.
•
Keep electrostatic-sensitive parts in their containers until they arrive at static-free
work areas.
•
Place parts on a grounded surface before removing them from the container.
•
Avoid touching pins, leads, or circuitry.
•
Use proper grounding practices when touching a static-sensitive component or
assembly.
Grounding Methods to Prevent Electrostatic Discharge
•
Use a wrist strap connected by a ground cord to a grounded chassis.
•
Use conductive field service tools.
•
Use a portable field service kit with a folding static-dissipating work mat.
Note:
If you do not have the suggested equipment for proper grounding,
arrange for an authorized reseller to install the part.
