I would like to know that the Power Supply 1200840L1 is same as 1200840G1 #240 or not? Presently I am using the L1 and my routers are working OK. But know Adtran recommends G1 # 240
I believe that the L vs G designation has to do with European RoHS compliance. Functionality should be the same.
There is no 1200840L1 all by itself. There are two possible options, as follows:
|NetVanta 5305 Redundant 120V AC Power Supply||1200840G1#120||Redundant 120VAC Power Supply module for the NetVanta 5305.|
|NetVanta 5305 Redundant 240V AC Power Supply||1200840G1#240||Redundant 240VAC Power Supply module for the NetVanta 5305.|
Note that the difference between them is the supported voltage, shown as a part number modifier as either #120 or #240.
