Note
Before you begin the upgrade process, review the list of chassis and modules that Cisco MDS NX-OS
Release 5.2(2) supports. See the
“MDS 9000 Chassis and Module Support” section on page 8
.
For detailed instructions for performing a software upgrade using Cisco DCNM, see the

Upgrading Guidelines Specific to NX-OS Release 5.2(2)
Follow these guidelines when upgrading to Cisco MDS NX-OS Release 5.2(2):
•
Follow the upgrade path to NX-OS Release 5.2(2) that is specified in
Table 11
.
•
Upgrade to NX-OS Release 5.2(x) before you install any Generation 4 module in an MDS 9500
Series switch. Generation 4 modules include the FCoE module and the 32-port and 48-port 8-Gbps
Advanced Fibre Channel modules. NX-OS Release 5.2(x) is needed for the switch to recognize the
new hardware.
•
Perform a full switch reload on an MDS 9509 or MDS 9506 switch after you install NX-OS Release
5.2(1) and install any Generation 4 module, including the FCoE module. The switch reload is
required for the new hardware to come up. Once you perform the switch reload, the fabric mode
changes to support the Generation 4 hardware. Because of the changed fabric mode, you cannot
subsequently perform a nondisruptive software downgrade from NX-OS Release 5.2(1). For
additional information, see the
“Downgrading Guidelines Specific to NX-OS Release 5.2(2)”
section on page 19
•
Ensure that you have a Supervisor-2A module (DS-X9530-SF2A-K9) installed in a MDS 9500
Series switch if you plan to use the Cisco MDS 9000 8-port 10-Gbps Fibre Channel over Ethernet
(FCoE) (DS-X9708-K9).
•
We recommend that you delete any SPAN configuration, Fibre Channel tunnel, or tunnel-ID map
configuration from your switch before you start the upgrade to NX-OS Release 5.2(1). You can save
the SPAN destination and SPAN target configuration and then reconfigure the SPAN session
following the upgrade. All SPAN destination and SPAN target ports are reinitialized after the
upgrade. To gather information about SPAN sessions and delete them, use the following commands
in this order:
–
show incompatibility systems bootflash:
image_name
to display any incompatible
configurations
–
show span session
to check the current configuration for a SPAN session
–
no span session
session-number
to delete a SPAN session
