Juniper Networks E-Series manual Upgrading Systems That Are Operating with Two SRP Modules

B-16

APPENDIX B

Installing JUNOSe Software

The procedures for transferring release files from a source E-series router to a destination E-series router are almost identical to transferring release files from a network host to an E-series router on the same side of the firewall.

Note: You must enable the FTP server on the source E-series router.

To transfer release files from a source E-series router to a destination

E-series router, follow the instructions in Installing Software When a

Firewall Does Not Exist, with the following changes:

•Substitute the source E-series router for the network host.

•Omit the step about mounting the CD.

•Copy the file to the system space of the second E-series router from the user space of the first E-series router.

Upgrading Systems That Are Operating with Two SRP Modules

Use this procedure if the system contains two SRP modules and is already operating with an earlier software release. Each SRP module will keep the system operational while you upgrade the software on the other, so that you can avoid interrupting service.

Caution: You must upgrade the software on the redundant SRP module when you upgrade the software on the primary SRP module. This action prevents the redundant SRP module from overwriting the new software on the primary SRP module if the primary SRP module fails and the redundant SRP module assumes control.

To upgrade the software on a system that is operational and contains two

SRP modules:

1Turn off autosynchronization.

host1(config)#disable-autosync

2Copy the new release of the software to NVS of the primary SRP module.

•If a firewall separates the E-series router from the network host, transfer files to the user space with the FTP client on the network host, and install files on the system space (see Installing Software When a Firewall Exists, earlier in this appendix).
