Juniper Networks T1600 Benutzerhandbuch

To prepare to upgrade the SIBs, follow this procedure:

1.

The T640 routing node must contain five standard SIBs or SIBs version B before
the upgrade. Verify that four SIBs are in the 

Online

 state and one SIB is in the

Spare

 state. Display the status of the SIBs by issuing the 

show chassis sibs

command:

user@host> show chassis sibs

Slot  State               Uptime
 0    Spare            255 days, 31 minutes, 12 seconds
 1    Online           255 days, 31 minutes, 12 seconds
 2    Online           255 days, 31 minutes, 12 seconds
 3    Online           255 days, 31 minutes, 12 seconds
 4    Online           255 days, 31 minutes, 12 seconds

To bring a SIB online, issue the 

request chassis sib online

 operational mode

command. To install additional SIBs, use the standard installation procedure
described in the T640 Internet Routing Node Hardware Guide.

NOTE: Do not proceed with the upgrade until all five SIBs are present and operational.
