Reliable Operation (A)(1)
Maximum Fuse Rating
(A)(2)
Baseband unit 10 20
(1) The recommended fuse rating corresponds to peak load and depends on the conguration.
(2) This value is the internal maximum fuse rating for the unit. General fuse dimensioning have to
take all external factors into account, such as local regulations and cable dimensioning.
3.2.1 Power Consumption
The power consumption values are presented as typical and maximum values,
for a unit with fan. The typical values are based on an air temperature of 20 °C
for the air entering the unit and a typical trafc load. The maximum values are
based on an air temperature of 55 °C for the air entering the unit and a maximum
trafc load.
Note: The power consumption for SFPs, SAU, or GPS is not included.
