Five T640-SIBs
If your T640 router already contains T-CBs and the new rear fan tray, but contains
standards SIBs, you can order and install a kit that contains only T640-SIBs. Figure 78
on page 163 and Figure 79 on page 163 illustrate the difference between a T640-SIB and
a standard SIB or SIB version B.
