Module 5 EPLD upgrade is successful
The Cisco Nexus 7000 Series system will reload as soon as the upgrade occurs.
Step 4 For releases 4.0(2) or earlier, if you updated the power management EPLD image, you must reset the
power for the module so that EPLD can take effect (this is not required for release 4.0(3) or later). You
can reset the power in one of the following two ways:
• To reset the power for the module, physically remove the module and reinstall it.
Note A module reload or just pressing the ejector buttons on the module is not sufficient for this reset
requirement.
• To reset the entire system, power cycle the system.
To confirm the EPLD upgrade, see the “Displaying EPLD Versions for an I/O or Supervisor Module”
section on page 6-37.
Caution Resetting the power disrupts any data traffic going through the affected modules. If you power cycle the
entire system, all data traffic going through the system at the time of the power cycling is disrupted. This
is not necessary for release 4.0(3) or later.
Note As of release 4.0(3) or later, the system automatically loads the new power management EPLD after an
upgrade, so it is no longer necessary to reset the power for the module or system.
Upgrading EPLDs for a Fabric Module
You can upgrade EPLDs for a fabric (Xbar) module while the system is operational if at least one other
fabric module is operational.
