This system contains boards with embedded power sources rated greater than 150 W.
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 assembled in the upper
part of the RTM slot on the backplane near the RTM alignment pin. The screw can be removed
according to field requirements.
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

The system is compliant to NEBS and ETSI acoustic noise emission standards, if the system is
equipped with Artesyn Embedded Technologies blades and with properly designed and
configured third party blades. In a system thus configured, the fans will settle at
approximately 12% speed at an ambient temperature of 23 ºC (+/- 2º C) (73.4 °F +/- 3.6 °F)
under normal operating conditions.
