4.3.5 Enabling Communication to Antenna Units

4.3.5.1 Auto configuration

In order to be able to communicate with the attached AUs, the HU requires information

on their unique identifiers (MID-numbers). This information is collected via the

command “discover”.

NOTE

Control of the attached AUs is not possible without first running the discover

command.

4.3.5.2 Manually adding AUs

If for some reason the “discover” command is not executed successfully the AUs

can be manually added to the system configuration. For this you need the unique

identifier of the AU, the MID number. This is an 8-digit hexadecimal (0-9, A-F) number

and can be found on the AU label. The AU is added using the “+addau” command.

EXAMPLE

The command “+addau 1 10F54D9A” adds the AU with the MID 10F54D9A to the

SFP port 1.

Adding the same AU to another SFP port deletes the old entry. Multiple entries of the

same MID are not possible.

4.3.6 Controlling the AU (276X and 277X)

Commands proceeded by ++ are Antenna Unit commands and routed to the currently

active AU. AUs are activated using the REID command. On activating a new AU its

current settings are displayed.

EXAMPLE

The command “reid au3” activates the AU connected to the SFP port # 3. All

commands proceeded by “++” are now directed to this AU.

4.3.6.1 Setting the Attenuator Values in the Antenna Unit

The attenuators in the AU are controlled using the “++dla” (DownLink Attenuator) and

the “++ula” (UpLink Attenuator) commands for the downlink and the uplink,

respectively. Before using this command, make sure that the correct AU is active.

EXAMPLE

To set the attenuation of the AU which is connected to SFP port # 7 to 3 dB, the AU

has to be activated using the command “reid au7”. Then the attenuation setting can

be changed using the command “++dla 3”.
