Upgrading to a T640 Standard SIB Version B

Copyright © 2013, Juniper Networks, Inc.
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
time, except during upgrade. To upgrade to standard SIB version B, you prepare the router
by placing it into upgrade mode, then replace each standard SIB with a standard SIB
version B.
NOTE: During the upgrade, the T640 router might experience some packet
loss, depending on the operational environment. For more information,
contact your customer support representative.
To upgrade for each of the SIBs in the T640 router:
