Servicing the BLA

The BLAH500 E Amplifier 700-900MHz provides diagnosis and servicing web 
pages relies on HTTP, allowing service access with any web browser.

Accessing the BLA Amplifier

6.1

The BLAH500 E Amplifier 700-900MHz is accessible via the BLA control board 
with its IP address.

The IP address is given during "

cf

" by using TOPSPIN 2.xx software on the 

workstation.

In case of problems :

Check the RJ45 cabling between amplifier, Ethernet switch and workstation.

Check the Ethernet switch power.

Check if the green LED on the amplifier RJ45 connector lights up.

Check the front panel of the amplifier, LED's indi32V, +15V, -15V and 
+3.3V ON must have lit.

To access the BLAH500 E Amplifier 700-900MHz, type "

ha

" in TOPSPIN 2.xx or 

better and choose the BLA that should be accessed or start your favourite web 
browser and type the given IP address as URL.
