Upgrading SSM160 to SSM440

Important - Interfaces ethX-Mgmt1 and ethX-Mgmt2 are no longer available.

To upgrade from SSM160 to SSM440:

1. Run the asg diag verify command. This gives you data to compare after the upgrade.

   If necessary, add licenses for 100G.

2. Put the Standby Chassis in administratively DOWN state.
3. Shut down all SGMs and SSMs on the Standby Chassis.
4. Replace the SSMs and wait until they are up.

   With SmartConsole, wait about 2 minutes and check that the port links are up.

5. Start all SGMs on the Standby Chassis.
6. When the SGMs are up, reboot again (because of the SSM change).
7. Apply QSFB mode on the Standby Chassis to align with the Active Chassis.

   If there are speed changes on ports 1 - 7 on SSM440, the SSM reboots again to align with the Active Chassis configuration.

8. Change QSFP Mode based on the Active Chassis, one SSM at a time. The SSM reboots.

   Initiate gClish on the Standby Chassis SGM. Use the set blade-range command in gClish only.

9. Put the Standby Chassis in administratively UP state.

To verify the upgrade:

1. Run the asg diag verify command and compare with the results from Step 1. The following tests can fail:
   1. When you run asg_port_speed verify from the Active Chassis (with SSM160), all should pass except for QSFP Mode.
   2. When you run asg_port_speed verify from the Standby Chassis (with SSM440) all should pass except for QSFP Mode and ports 17 - 40. (The Active Chassis should show N/A).
   3. The configuration file test on asg diag will fail due to differences in the /config/active file (the SSM type, ports amount, port link speed, and SSM QSFP Mode).
   4. SSM QoS test on asg diag will fail because of different port IDs between Chassis. After you upgrade both Chassis, the SSM QoS will work.
   5. The MAC setting test on asg diag will fail when you run it from the SSM440 Chassis. The MAC will fail on the Chassis with SSM160 on ports 17 - 40.
2. Fail over and upgrade the other Chassis.
3. After both Chassis are upgraded, use gClish to increase the matrix size to 16K.
