Inserted a 1g transceiver (MGBIC) into one of the two "10g" port slots per switch.

The 1-gigabit MGBIC will not function, though a 10-gigabit 10GBASE works fine in the same slot.

B5 hardware only supports 10g transceivers (10GBASE) within the two port slots labeled "10g".

Functions as Designed (FAD).

These B5 switches also contain two combo (5489) "SFP" port slots for 1g MGBIC insertion.

Alternately, the C5-Series (C5K125-24, C5K125-24P2, C5K125-48, C5K125-48P2, C5K175-24) does support a dual 10g/1g SFP+ capability via two "SFP+" port slots per switch.
