Fans and airflow
Fan installation is done as part of the factory install and is based on the stock keeping unit (SKU) type. The VEP1405 series of
systems support a DC fan unit with fan airflow starting from the bottom of the unit:
Four core unit with single fan
Eight core unit with two fans
Sixteen core unit with two fans
Position the unit in a well ventilated environment with clearance around the exhaust vents. The fan speed varies based on
internal temperature monitoring. The platform never intentionally turns off the fans.
CAUTION: The fans are not field-replaceable.
CAUTION: For thermal considerations, do not stack the VEP1405 series platforms on top of each other. Do not
place the external power supply on top of the VEP1405 series unit. Stacking the units or placing the power
supply on top of a unit impairs cooling.
Power
Connect the platform to the applicable power source using the appropriate power cable. The VEP1405 series of systems ship
with one external AC/DC power supply and one AC power cable.
When installing AC platforms, follow the requirements of the National Electrical Code ANSI/NFPA 70, where applicable.
The platform is powered-up when the power cable is connected between the platform and the power source.
CAUTION: Before servicing, ensure that the power cable is disconnected.
CAUTION: Use the power supply cable as the main disconnect device. Ensure that the socket-outlet is located
near the equipment and is accessible.
Storing components
If you do not install the VEP1405 series unit and components immediately, properly store the platform and all optional
components following these guidelines:
The storage temperature range is from -40°C to 70°C (-40°F to 158°F) with humidity at 5% to 90% noncondensing
Store on a dry surface or floor, away from direct sunlight, heat, and air conditioning ducts
Store in a dust-free environment
NOTE:
ESD damage can occur when components are mishandled. Always wear an ESD-preventive wrist or heel ground
strap when handling the platform and its accessories. After you remove the original packaging, place the VEP1405 series
unit and its components on an antistatic surface.
