To mate the connectors, the mating axes of both connectors must be aligned. The "click" will confirm
the fully mated connection. Do not attempt to insert on an extreme angle: insert the RF plug
connectors vertically into the ANT1 / ANT2 RF receptacles of the modules, as described in
Figure 71 .

Figure 71: Precautions during RF connector mating
To unplug the RF cable assembly it is encouraged to use a suitable extraction tool for the RF
connector, such as the Hirose U.FL-LP-N or the Hirose U.FL-LP(V)-N extraction jig, according to the
RF cable assembly type used. Hook the end portion of the extraction jig onto the connector cover and
pull off vertically in the direction of the connector mating axis, as described in
Figure 72 .

Figure 72: Precautions during RF connector extraction
Any attempt to unplug the RF connectors by pulling on the cable assembly without using a suitable
extraction tool may result in damage and affect the RF performance.
Do not forcefully twist, deform, or apply any excessive pull force to the RF cables or damage the RF
connectors, otherwise the RF performance may be reduced.
2.14 Thermal guidelines
☞
Modules’ operating temperature range is specified in TOBY-L2 Data Sheet [1] and MPCI-L2 Data
Sheet [2] .
The most critical condition concerning module thermal performance is the uplink transmission at
maximum power (data upload in connected-mode), when the baseband processor runs at full speed,
radio circuits are all active and the RF power amplifier is driven to higher output RF power. This
scenario is not often encountered in real networks (for example, see the Terminal Tx Power
