Determine the order to replace the existing SCB-MXs with upgraded ones. SCB 0 is
associated with RE0, and SCB 1 is associated with RE1.
NOTE:
Do not add or remove any router hardware during the upgrade
procedure.
Upgrade the SCB-MX in the Backup Routing Engine
TIP:
The MX480 has two slots for the SCB-MX—that is, SCB 0 and SCB 1—and
these correspond to RE0 and RE1 respectively, where SCB 1 is the first
SCB-MX.
To upgrade the SCB-MX in the backup Routing Engine:
1.
Power down the backup Routing Engine from the master Routing Engine by issuing
the
request system power-off other-routing-engine
command.
2.
Verify that the Routing Engine is powered down by issuing the
show chassis
routing-engine 1
command. The slot of the Routing Engine may be 0 or 1, and is shown
as 1 in this example:
user@host>
show chassis routing-engine 1
Routing Engine Status:
Slot 1:
Current State Present
Ensure that the Current State is Present, which indicates that the Routing Engine is
offline.
3.
Take the fabric plane offline by issuing the
request chassis fabric plane 4 offline
command. SCB 1 has four fabric planes numbered, 4, 5, 6, and 7.
4.
Verify that the fabric plane 4 is offline by issuing the
show chassis fabric summary
command.
