6.10 Final Reassembly
Important You must refit the correct type of front panel to your
TB8100 BSS. There are several small but important differ-
ences between the front panel for a 5W or 50W BSS and
the front panel for a 100W BSS. These differences are in
the duct for the PA fan and are described in the following
paragraphs.
5W or 50W Front
Panel
The PA fan duct does not have the cut-outs b required for the 100W PA
RF and DC cables. The break-off tab
c will also still be present and will
jam on the system control bus. Do not try to fit this front panel to a 100W
BSS or you will damage these cables and possibly the front panel itself.
100W Front Panel Do not fit this front panel to a 5W or 50W BSS. The presence of the cut-
outs and absence of the break-off tab will allow air to escape and reduce the
velocity of air directed through the heatsink.
