VOLUME III, CHAPTER 2, IRU 600 INSTALLATION
Expansion Port Use
The expansion port allows system expansion through the addition of co-located IRU
600 radios, or external radio equipment.
When multiple carriers are deployed on a common branching network (same
antenna), the selection and installation of branching network components must be
such that threshold degradation caused by intermodulation products is avoided.
While the IRU 600 ACUs are specified to avoid placing undue constraints on
frequency planning for multiple carrier systems, the following conditional require-
ments are intended to provide a guidelines for such systems, which may require
extra diligence in the selection and installation of branching components.
l The intermodulation frequency products that result from combining two or
more transmitter frequencies on a common antenna feeder should be 48MHz
or more above or below each of the receiver frequencies present on the same
antenna feeder.
l Systems employing carrier frequencies with potential intermodulation
products within 48MHz of any of the receiver frequencies present on the same
antenna branching network (feeder) must be designed and installed to
mitigate the effects of the potential intermodulation products.
FAN Module
The fan units in an RFU are removable for service/replacement. Fan module replace-
ment is non traffic affecting.
l For IRU 600(v1) and IRU 600v2 a fan cover is removed to expose the two
fans. Removal and replacement is per-fan.
l For the IRU 600v3 the four fans are located on a removable/replaceable front-
cover fan tray.
o
To remove, unscrew the fan tray fasteners, ease outwards and carefully dis-
connect the rear cable connector. Fan replacement is per-tray.
l Fan operation is monitored. Each fan has a matching alarm.
l For IRU 600(v1) and IRU 600v2 both fans are operated at a fixed speed.
l For IRU 600v3 the fans are currently operated at a fixed speed. Temperature-
dependent speed will be introduced in a subsequent SW release.
If one fan needs to be replaced, replace al l fans.
