Figure 2-52 POD-H-CDU
2.1.13.1 Functions and features
- Provides cable routing space when RF, optic, DC power, and Ethernet cables are connected between the
modules or units in POD DAS system.
- Has good space efficiency since H-FAU can be installed behind H-CDU
2.1.14 POD-H-FAU
Figure 2-53 POD-H-FAU
2.1.14.1 Functions and features
- Installed right above the H-SRU for dissipating heat comes from the modules installed in POD-H-SRU.
- Good space efficiency since H-FAU can be installed behind H-CDU
- DC Power is provided from FAN port located in the back side of H-SRU
- FAN speed control and FAN on/off is controlled automatically by H-SCM based on the temperature of
modules installed in H-SRU.
- FAN fail alarm is monitored by H-SCM.
2.1.14.2 The rules for installing FAN unit
- When the number of module installed in a POD-H-SRU is less than 5, it doesn’t need the installation of H-
FAU.
- When the number of module installed in a POD-H-SRU is more than 6, It needs the installation of POD-H-
FAU.
 We strongly recommend that each module should be installed every other slot in a POD-H-SRU.
- When POD-H-SRUs more than 2 are stacked in one rack, one POD-H-FAU per 2 POD-H-SRU should be
installed regardless of the number of module installed in one POD-H-SRU.
 We strongly recommend that each module should be installed with sufficient gap as far as possible
when the modules in a POD-H-SRU are not fully installed.
2.1.14.3 Port
- H-FAU must be connected with FAN port which is located in the back of H-SRU (refer to Figure 2-9) by
provided signal cable.
