3.5 How to power up the MTS4-outdoor enclosure (cold start)
Introduction
This section will guide you through how to power up the MTS4-outdoor enclosure after
installation and power has been connected.
The procedure is split into to scenarios depending on state of installation.
Scenario 1: Anten-
nas
installed
If all antennas are installed and connected to a MTS4 base station it is allowed in prin-
ciple to switch on all circuit breakers at one time, but the procedure below is the better
way to check for correct function of installed equipment.
Scenario 2: Anten-
nas not installed
If antennas not installed or other reasons for not powering up the base station.
If all antennas are NOT installed and connected to a MTS4 base station or if the base
stations are not ready for “going in the air” then only do step 1 to 4. Before continuing
with step 5 to 14 the following must be done.
Step
Action
Do before
step 5
The power supply plugs shall be disconnected
from the base radios. Carefully pull out the
power supply plug.
Do before
step 5
The MTS4 Base station may have up to 4 x
Base Radio’s.
The power supply plug shall be disconnected
on all Base Radios in the MTS4 rack.
Doing this will ensure that no Base Radio will be damaged or unintentionally transmit. It
will also ensure that heating is enabled and external equipment (modem / microwave)
can have 48DVC supply. Now it is safe to continue with step 5 to 14.
