NOTE: Before you install one or more FPC4s in a T640 router that is not part
of a routing matrix, you must replace each SIB in the router with a SIB
version B.
SIB version B is supported in Junos OS Release 7.3 and later.
Standard SIBs and SIB version B cannot be installed in the same chassis at the same

version B.
NOTE: During the upgrade, the T640 router might experience some packet
loss, depending on the operational environment. For more information,
