1.4.1 HX 2.5 GHz TDD External Interfaces
The HX 2.5 GHz TDD front panel includes the multiplexer interfaces (e.g. antenna port, DL Test port, wideband RU
port), system level status LEDs and service maintenance ports.
Note: Both SISO and MIMO models include two sets of multiplexer RF interfaces. For SISO models, the RF
connections will be performed via the connectors corresponding to the installed HX remote unit module (inside chassis):
Left MUX for Left HX 2.5 GHz Module and Right MUX for Right HX 2.5 GHz Module. See section
 1.4.2 for internal
modules.
