Rack Installation Safety Instructions
Review the following guidelines to help ensure your safety and protect the equipment from
damage during the installation.
•
Only trained and qualified personnel should be allowed to install or replace this
equipment.
•
Verify that ambient temperature of the environment does not exceed 50
°
C (122
°
F)
•
To maintain a low center of gravity, ensure that heavier equipment is installed near the
bottom of the rack and load the rack from the bottom to the top.
•
Ensure that adequate airflow and ventilation within the rack and around the installed
components so that the safety of the equipment is not compromised. It is recommended
to allow for at least about 2 cm of airspace between devices in the rack.
•
Verify that the equipment is grounded as required – especially the supply connections.
4.2.3
Single Building Rack Installation
This section provides an example of a single building main communication room installation
for a 24-floor building with Cellular and PCS coverage.
Since there are 24 floors, then 24 RHUs are required – one for each floor. In addition, the
following equipment will be installed in the main communication room:
•
Three BUs – to support 24 RHUS
•
One 430 controller for monitoring
•
One RIU with Cellular and PCS BTSCs – to interface to the BTS/BDA
