Five SIBs are installed in the T640 router. The SIBs are located in the rear of the chassis
in the slots marked through
SIB0
SIBs are hot-insertable and hot-removable.
NOTE: SIB version B is supported in Junos OS Release 7.3 and later. You can
use a SIB or SIB version B in a chassis running Junos 7.3 or later, but you cannot
use both on the same chassis at the same time.
If you use one or more FPC4s or Enhanced Scaling FPCs in a T640 router that
is not part of a routing matrix, each SIB in the router must be a SIB version B.
NOTE: The T640-SIB requires Junos OS Release 7.0 or later.
