Using the Software Install Wizard
Figure 15-8 Download and Install Status Dialog Box
Note On hosts where the TFTP server cannot be started, a warning is displayed. The TFTP server may
not start because an existing TFTP server is running or because access to the TFTP port 69 has
been denied for security reasons (the default setting on Linux). In these cases, you cannot
transfer files from the local host to the switch.
Note Before exiting the session, be sure the upgrade process is complete. The wizard will display a
status as it goes along. Check the lower left-hand corner of the wizard for the status message
Upgrade Finished. First, the wizard displays the message Success followed a few seconds later
by InProgress Polling. Then the wizard displays a second message Success before displaying the
final Upgrade Finished.
Upgrading Services Modules
Any Fibre Channel switching module supports nondisruptive upgrades. The 14/2-port Multiprotocol
Services (MPS-14/2)) module supports nondisruptive upgrades for the Fibre Channel ports. Any
software upgrade for the two Gigabit Ethernet ports in this module is disruptive. See Chapter 52,
“Configuring IP Storage” for more information on MPS-14/2 modules.
Caution Any software upgrade for the Caching Services Module (CSM) and the IP Storage (IPS) services
modules is disruptive.
CSMs and IPS modules use a rolling upgrade install mechanism to guarantee a stable state for each
module in the switch:
