Operational Considerations when Removing Crossbars

The Cisco MDS NX-OS software does not support the following hardware: Supervisor-1 module, the
Note
IPS-4 and IPS-8 storage modules, the Cisco MDS 9216 switch, the Cisco MDS 9216A switch, the Cisco
MDS 9020 switch, the Cisco MDS 9120 switch, and the Cisco MDS 9140 switch.
Generation 2 hardware includes the following:
• Cisco MDS 9513 Director chassis
• Supervisor-2 module
• MSM-18/4 Multiservice Storage module
• Cisco MDS 9222i Module-1 module
• 48-port 4-Gbps Fibre Channel switching module
• 24-port 4-Gbps Fibre Channel switching module
• 12-port 4-Gbps Fibre Channel switching module
• 4-port 10-Gbps Fibre Channel switching module
The Cisco MDS NX-OS software on the Cisco MDS 9500 Series Directors supports the following types of
crossbars:
• Integrated crossbar—Located on the Supervisor-1 and Supervisor-2 modules. The Cisco MDS 9506 and
• External crossbar—Located on an external crossbar switching module. Cisco MDS 9513 Directors
Generation 1 hardware includes the following:
• Cisco MDS 9506 and 9509 Director chassis
• Supervisor-1 module
• 32-port 2-Gbps Fibre Channel switching module
• 16-port 2-Gbps Fibre Channel switching module
• 8-port IP Storage Services (IPS-8) module
• 4-port IP Storage Services (IPS-4) module
• Storage Services Module (SSM)
• 14/2-port Multiprotocol Services (MPS-14/2) module
Operational Considerations when Removing Crossbars
You can mix and match Generation 1 and Generation 2 hardware on the Cisco MDS 9500 Series Directors
running Cisco MDS NX-OS software without compromising the integrity and availability of your SANs based
on Cisco MDS 9500 Series Directors.
To realize these benefits, you must gracefully shutting down the crossbars and consider the backward
compatibility of the Generation 1 modules.
