NOTE: 1. The QFX3500 has two banks for the Jloader image and requires that both are upgraded. The procedure listed provides the steps for upgrading both banks.
2. For Junos 11.3R1 and 11.3R2, the jloader image has to be installed using the no-validate option, or else the installation will fail with incompatible configuration error. This is not required for Junos 11.3R3 and above.
3. Following the completion of the jloader upgrade for the first bank, the package will be deleted after the reboot and will need to be downloaded or copied from /var/sw/pkg so that it is available for the upgrade of the second bank.
Download the loader software package from the Juniper Networks website and place the software package on an internal software distribution site or in a local directory on the switch. We recommend using /var/tmp as the local directory on the switch. NOTE: The jloader image can be downloaded from PSN-2011-05-258 link listed below.
