3. Press ejector release buttons located at the center of the crossbar module to push out the ejector
levers and to disconnect the module from the backplane.
Warning : You must be cautious when the ejector levers swing open and stay open during
installation and removal process.
4. With a hand on each ejector, pull the module part way out of its slot in the chassis.
5. Grasp the front edge of the module and slide the module partially out of the slot. Place your other hand
under the module to support the weight of the module. Do not touch the module circuitry.
6. Place the module on an antistatic mat or antistatic foam, or immediately reinstall it in another slot.
Nondisruptive Migration from Crossbar Fabric-1 Switching Modules to
Crossbar Fabric-3 Switching Modules
This section describes the steps required to migrate all the Crossbar Fabric-1 Switching Modules to
Crossbar Fabric-3 Switching Modules for the IBM SAN384C-6 and SAN768C-6 Directors.
This section includes the following topics:
• "Requirements" on page 117
• "Components used" on page 117
• "Prerequisites" on page 117
• "Migration procedure" on page 118
• "Verification" on page 120
• "Recovery procedure" on page 120
• "Troubleshooting" on page 121
Note : Before you install, operate, or service the system, read the IBM Systems Safety Notices for
important safety information.
Requirements
It is recommended that you have knowledge of the NX-OS operating system CLI.
Components used
The information in this document is based on the following software and hardware versions:
• SAN384C-6 Director or a SAN192C-6 Director with NX-OS Release 8.4(1)
• SAN384C-6 Crossbar Fabric-3 Switching Module. For SAN192C-6, it is SAN192C-6 Crossbar Fabric-3
Switching Module.
• SAN384C-6 Crossbar Fabric-1 Switching Module. For SAN192C-6, it is SAN192C-6 Crossbar Fabric-1
Switching Module.
Prerequisites
• Ensure that the switch (SAN192C-6 and SAN384C-6 Switch) has software release version Cisco NX-OS
Release 8.4(1) or later. On SAN768C-6 Multilayer Director Switch, ensure that the switch is running on
Cisco NX-OS Release 8.4(2a) or later. To upgrade an image version on the switch, refer the Cisco 9000
NX-OS Software Upgrade and Downgrade Guide, Release 8.x guide.
• When the SAN384C-6 or SAN192C-6 chassis has 6 x Crossbar Fabric-1 Switching Modules installed,
you must migrate a minimum of 3 x Crossbar Fabric-1 Switching Modules to Crossbar Fabric-3
Switching Modules, and remove the remaining 3 x Crossbar Fabric-1 Switching Modules to support full
bandwidth to 32-Gbps fiber channel switching modules.
