AT-SB4215 Bandwidth Expander
The bandwidth expander card achieves the performance of the dual
controller configuration, without incurring the cost of a second controller
card.
The bandwidth expander card is used in controller slot B to utilise unused
internal ports, i.e. those ports that would normally be assigned to line
cards 5 to 8 on the 8 slot chassis. This achieves the same level of
performance as using two controller cards. It does not, however, provide
the redundancy obtained by the dual controller card configuration.
