System Administrator Guide
Procedure 8-21 To perform an ISSU or on-demand software upgrade
on a 7210 SAS, 7450 ESS, 7705 SAR, 7710 SR, 7750 MG, 7750 SR, or
7950 XRS
Perform this procedure to upgrade the device software on one or more NEs. The
following must be true before you attempt a device software upgrade.
• You have a 5620 SAM user account with an administrator or network element
software management scope of command role or a scope of command role with
write access to the mediation package. See chapter 2 for more information
about scope of command roles.
• The FTP or secure FTP credentials are configured in the NE mediation policy.
See the 5620 SAM User Guide for more information.
Warning — A device may require a firmware upgrade before a
software upgrade. To avoid a service outage, ensure that the device
firmware version supports the software version. See the device
software Release Notes for information about firmware and software
version compatibility and the firmware upgrade procedure.
Caution 1 — Alcatel-Lucent recommends that you open a physical
console session on the device that you need to upgrade. The console
session allows you to monitor the upgrade and recover in the event of
an upgrade failure.
Caution 2 — Read the software upgrade information in the device
documentation before you perform a software upgrade.
Caution 3 — Before you attempt an ISSU, see the appropriate device
release notice and the 5620 SAM Network Element Compatibility Guide
for information about the supported upgrade paths. See section 8.1 for
general ISSU information.
Caution 4 — You cannot upgrade a device to a release that is
chronologically older than the currently installed release. For example,
you cannot upgrade from Release 10.0 R8 to 11.0 R1, because Release
11.0 R1 predates Release 10.0 R8. See the 5620 SAM Network Element
Compatibility Guide for information about the supported upgrade
paths.
