To support a high availability Base Station, the fan tray includes 10 brush-less fans, where 9 fans are sufficient for cooling a fully loaded chassis
Failure in any of the fans is indicated by both the front panel LEDs and a trap that is sent to the management system
To further support high availability, the chassis may operate with the hot-swappable fan tray extracted from it for a period of time sufficient for replacing it (up 10 to minutes)

Base Station Shelf Components Power Interface Unit (PIU)
• The interface between the base station site’s DC power source (48 VDC) and the Base Station chassis power supply
• Filters and stabilizes the base station input power and protects the system from power problems such as over voltage, surge pulses, reverse polarity connection and short circuits
• Filters high frequency interference (radiated emissions) and low frequency interference (conducted emissions) to the external power source
• Each base station chassis contains two slotsfor an optional 1+1 PIU redundancy
• One PIU is sufficient to support a fully populated chassis
• Two PIU modules provide redundant power feeding (two input sources) while avoiding current flow between the two input sources
• Remove the PIU only after disconnecting itspower cord, failure to comply may cause damage to the equipment

Base Station Shelf Components IF Cable
• The AU-ODU is connected to the AU-IDU/Micro Base Station via an IF cable carrying both signals and power
• The maximum permitted attenuation of the IF cable at applicable frequencies depends on its screening effectiveness and its maximum permitted DC resistance
• To comply with the required screening effectiveness requirement, it is recommended to use double shielded cables
• Following are the cables that recommended by Alvarion and their maximum length
– LMR-195 80 m
– LMR-240 150 m
• The IF cable carries– Full duplex data– Control and management signals – Power (-48 VDC) – 64 MHz synchronization reference clock
from the IDU to the ODU– IF Frequencies
• Tx: 240 MHz • Rx: 140 MHz
– IDU-ODU service channel at 14 MHz serves for bi-directional control, status and management signaling
Micro Base Station Components Micro Base Station Indoor Unit
• Provides the full base station functionality necessary for serving a single sector
• There are two different models
– Powered from the AC mains (100 - 240 VAC)
– Powered from a -48 VDC power source
• The functionality of the Micro Base Station is very similar to the combined functionalities of NPU and AU-IDU modules of the modular Base Station
– Backbone Ethernet connectivity via a 10/100 Base-T network interface
– Traffic classification and connection establishment initiation
– Policy based data switching
– Service Level Agreements management
– Centralized agent for management the Micro Base Station unit and all registered SUs
– Alarms management, including external alarm inputs and activation of external devices (future option)
Micro Base Station Components Micro Base Station Indoor Unit
• An SNMP agent incorporated into the unit enables extensive In-Band (IB) management of the Micro Base Station and all its registered SUs
• Out-Of-Band (OOB) management is supported through a dedicated 10/100 Base-T interface
• A serial RS-232 port supports local configuration, monitoring and debugging
• The Micro Base Station also contains the wireless IEEE 802.16a MAC and modem
• The Micro Base Station also includes two 3.5/1.75 MHz PHY channels
• The number of SUs that connect to the microBST might be limited than the specification, depends on the microBST license
