Ground Block; Restricted Access Location; Approved Grounds - Avaya G350 Installing And Upgrading

Installing the Avaya G350 Media Gateway

Ground block

A ground block, supplied by the customer and installed by an electrician, is available for use
when you are installing multiple G350 Media Gateways . The ground block, intended for rack
mounting, has ten terminals available for terminating Supplementary Ground Conductors. Up to
ten G350 Media Gateways can be grounded at the block installed close to the equipment (on a
rack) and then a single ground conductor can be routed from the same block to an approved
ground.

DANGER:
Failure to install both grounds will void the Product Safety certifications (UL and
DANGER:
the CE Mark) on the product, as well as allow a hazard to be present that could
result in death or severe personal injury.

Restricted Access Location

In Finland, Norway, and Sweden, the G350 Media Gateway must be installed in a Restricted
Access Location, due to unreliable earthing concerns. A Restricted Access Location is defined
as access that can be gained by only Service Personnel or Customers who have been
instructed about the reasons for the restricted access and any safety precautions that must be
taken. In these cases, access to the G350 is gained by the use of a tool (such as a lock and
key) or other means of security.
