CAUTION
If you do not correctly align the keyholes on the mounting bracket with
the hooks on the sunshield, the sunshield can crack.
CAUTION
Take care not to damage the cooling fin array at the top of the remote unit
when installing the sunshield.
CAUTION
If you do not secure the sunshield with a padlock or a bolt with washers
and nut, the sunshield may come loose in strong winds and cause
damage.
CAUTION
Always use the Ericsson sunshield, with the original factory paint.
Painting the sunshield can adversely effect the operating temperature of
the RBS. If the unit absolutely must be painted (e.g., for zoning reasons),
Ericsson will work with you to find a solution. If you paint the sunshield
of the unit without the approval of Ericsson, you will void Ericsson’s
warranty on that unit.

Each CDMA module and each RF chain will throw a fault when the
associated sunshield is opened. Thus, for a 4x3 RBS system, opening the
main sunshield will throw four faults (one for each CDMA module, and
opening a remote sunshield will throw a fault through each of two
different CDMA modules (one for each RF Chain.)

One of the four sets of LEDs on two signal surge
modules. The LED labeled “Alarm 1”
corresponds to the CDMA module for that
section of the signal surge module. The LEDs
labeled “Alarm 2”, “Alarm 3”, and “Alarm 4”
correspond to RF Chains 1, 2, and 3 for that
CDMA module, respectively. The LED labeled
PWR will be green when power is supplied to the
associated CDMA module.
This set of LEDs is used by CDMA module D.

CAUTION
Always use the Ericsson sunshield, with the original factory paint.
Painting the sunshield can adversely effect the operating temperature of
the unit. If the unit absolutely must be painted (e.g., for zoning reasons),
Ericsson will work with you to find a solution. If you paint the sunshield
of the unit without the approval of Ericsson, you will void Ericsson’s
warranty on that unit.
