Complete The Scbe-Mx Upgrade - Juniper MX960 Hardware Manual

Complete the SCBE-MX Upgrade

1. Verify if there are any MPCs running at 3G instead of 6G:
user@host> request chassis fabric upgrade-bandwidth info
Slot State
0 Upgrade not supported
1 Upgraded
2 Empty
3 Empty
4 Empty
5 Empty
6 Empty
7 Empty
In this example, the results indicate that slot 0 does not support the upgrade and slot 1 needs upgrade.
NOTE: The SCBE line card supports only DPC, MS-DPC, MPC1, MPC2, and MPC3 line
cards for the upgrade-bandwidth. If line cards that do not support the command option
are present in the chassis during the SCB-MX to SCBE-MX upgrade, the request chassis
fabric upgrade-bandwidth commands will return Upgrade not supported for the slot(s)
that contain the unsupported line card(s).
2. Upgrade the bandwidth of all MPCs by issuing the request chassis fabric upgrade-bandwidth fpc all
command. If you want to control the MPC line card upgrade, go to Step 3.
CAUTION:
upgrade order or if only one old MPC is present in the chassis. Running this
command may result in a loss of traffic across that MPC. Using this method may
increase that loss, as it does not consider any redundancy or graceful switchover
strategies that you may have configured on the system.
3. Issue the request chassis fabric upgrade-bandwidth fpc slot 1 command to upgrade the MPC in slot
1.
4. Verify that the MPC is upgraded:
user@host> request chassis fabric upgrade-bandwidth info
Use this command only if you are not concerned with the slot
