Combining Modules and Supervisors

All the existing Generation 1 and Generation 2 switching modules are supported by Cisco MDS SAN-OS
Release 3.0(1) and later. However, there are limitations to consider when combining the various modules
and supervisors in the Cisco MDS 9500 Series platform chassis.
You can combine Generation 1 and Generation 2 switching modules with either Supervisor-1 modules
or Supervisor-2 modules. However, combining switching modules and supervisor modules has the
following limitations:
•
•
•
Note You cannot downgrade from a Supervisor-2 module to a Supervisor-1 module.

Initial Troubleshooting Checklist

Begin troubleshooting Generation 1 and Generation 2 module issues by checking the following issues:
Checklist
Verify the port index allocation if a newly inserted module does not power up.
Check that the interface that you plan to use is not set to out-of-service.
Verify appropriate port rate mode and port speed for your configuration.
Ensure that both ends of a 10-Gbps link terminate in 10-Gbps ports.
Verify that no Supervisor-1 modules are used in a Generation 2 switch.
Use the show interface transceiver CLI command to view enhanced diagnostics on the X2 transceivers
for Generation 2 modules. This is supported on 4-Gbps and 10-Gbps ports. Use these diagnostics to
isolate physical layer problems, like contact problems, major failures within SFPs, or abnormal error
rates associated with excessive optical attenuation. The diagnostic information includes temperature,
voltage and current, transmit power level, and receive power level.

Generation 1 and Generation 2 Issues

This section describes troubleshooting issues for Generation 1 and Generation 2 modules and includes
the following topics:
•

•
•
OL-9285-05
Use a Supervisor-2 module and all Generation 2 modules in a chassis to get up to 1020 port indexes.
Use the show port index-allocation CLI command to determine available port index values before
inserting new modules in a chassis if you have a mix of Generation 1 and Generation 2 modules.
Use only Supervisor-2 modules on a Cisco MDS 9513 director.
