Centellis 4100 Installation and Use (6806800D82E) 60
This system contains boards with embedded power sources rated greater than 150W.
To support NEBS compliance (Telcordia GR-1089-CORE, section 9.8.2, requirement R9-14)
shelf ground (chassis ground) and logic ground (logic signal return) are connected to the shelf
at the backplane with a screw assembled for that purpose. This screw is located at the system's
rear at the lower part in the middle of the backplane, marked with the corresponding
grounding symbol. Artesyn Embedded Technologies - Embedded Computing recommends
not to remove this screw.
For more information please refer to Telcordia GR-1089-CORE, section 9.8.2, requirement R9-14.
In the AdvancedTCA Specification the connection of shelf ground to logic ground is described as
an option.
To satisfy the requirements for marking electrical and electronic equipment in accordance
with article 11 (2) of Directive 2002/96/EC, Waste from Electrical and Electronic Equipment
(WEEE), Artesyn Embedded Technologies - Embedded Computing includes a crossed-out bin
symbol on all standard and noncustom chassis product. This marking fulfills the requirement
set out by WEEE that a producer of an electrical or electronic appliance that bears their trade
name and is put on the European Union market after 13 August 2005, places a clearly
The products listed in the ordering information for spare parts and accessory kits are designed to
meet the Directive on the restriction of the use of certain hazardous substances in electrical and
electronic equipment (RoHS), DIRECTIVE 2002/95/EC.
The system is compliant to NEBS and ETSI acoustic noise emission standards, if the system is
equipped with Artesyn Embedded Technologies - Embedded Computing blades and with
properly designed and configured third party blades. In a system thus configured, the blowers will
settle at approximately 35% speed at an ambient temperature of 23ºC (+/- 2ºC) (73.4°F +/- 3.6°F)
under normal operating conditions.
