a. The MSP basic devices MSP32 and MSP42 support a PoE power budget of 120 W. You
cannot expand the PoE power budget of the basic devices with media modules.
b. Temperature of the ambient air at a distance of 2 in (5 cm) from the device
c. Hirschmann recommends to use SFP transceivers with “EEC” extension.
d. Use SFP transceivers with the “EEC” extension only, otherwise the standard temperature
range applies.
