Checking the trunk modules
One or both middle slots in the rear of the chassis of the Stinger FS and Stinger FS+
can contain a trunk module. Each trunk module supports connection to either optical
or copper media, depending on the type of module supplied. These center rear slots
are physically numbered as slots 8 and 9 to correspond to the slot numbering across
the front of the chassis. However, they are logically referred to by the operating
system as slots 17 and 18.
