16 Installation of the G350 Media Gateway
December 2003
Site requirements
Inspect the site before you begin the installation. Verify that the site requirements have been met for
adequate environmental conditions, power and grounding availability, safety, and security conditions. If
you find discrepancies between the specifications necessary for proper installation of equipment and the
conditions on site, contact your supporting technician before proceeding with the installation.
The G350 may be installed in a 19” rack, mounted on a wall, or placed on a sturdy table. Installation
instructions are provided in Chapter 2, “Installing the Avaya G350 Media Gateway”. The surrounding
temperature should be in the range 0-40 C. The humidity should not be higher than 95%.

Environmental Verification

Verify that temperatures and clearances are within the recommended technical parameters. Consult the
table of Technical Specifications in Appendix A, “Technical specifications”.
!
WARNING:
Verify that temperature and clearance ranges are within tolerable limits. The thermal sensors may
shut down equipment if it is subjected to conditions beyond the recommended limits. Equipment
can be damaged if these restrictions are not respected.

Power Verification

Check that an adequate number of power outlets are available.Verify that the G350 Media Gateway and
the other equipment in the rack do not present a possible overcurrent or overload to the customer's branch
circuit and/or power distribution strip. Power requirements are listed in Appendix A, “Technical
specifications”.
!
WARNING:
Do not overload the power circuit.

Grounding Verification

Ensure that the installation site has access to approved grounds and that either a trained technician or a
licensed electrician will be verifying all grounds and installing the Supplementary Ground Conductor
(consult Step 3: Attach ground conductors on page 27).
!
WARNING:
Installation in a Restricted Access Location and secure access are required in Finland and Norway.
The G350 Media Gateway relies on two ground connections (mains plug with an earth contact and a
permanent Supplementary Ground Conductor). Because of unreliable earthing concerns in Finland,
Norway, and Sweden, the G350 Media Gateway must be installed in a Restricted Access Location
(RAL). An RAL is defined as an access that can be gained only by trained 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 Media Gateway is gained by the use of a tool (such as a lock
and key) or other means of security.
If you have any questions about the safety conditions, contact your supporting technician. When you
have verified that the site is ready for a safe installation, proceed with the installation.
