Note:
The Model 5000BH and 5000BHC backplanes are identical with the
exception of an additional shared 100 Mb/s backplane on the Model
5000BHC. The Model 5625HD switch module does not connect to these
shared backplanes. The Model 5625HD switch module can be used with the
Model 5000BH and 5000BHC backplanes without altering the module’s
performance.
