Configuring EPLDs
When you upgrade both supervisor modules in a switch, Cisco NX-OS upgrades the EPLD images for
the standby supervisor module and then upgrades the active supervisor module. This action enables the
upgrade of supervisor modules to be nondisruptive to switch operations.
Note When upgrading EPLD images for Supervisor 2 or Supervisor 2E modules in a two-supervisor switch,
the standby supervisor will reset twice towards the end of that upgrade but the upgrade continues to
completion and the console displays the upgrade status.
When you upgrade supervisor module in a single-supervisor switch, the operation is disruptive to switch
operations if the switch is active.
To start the installation of all new EPLD images for all modules in a switch, use the install all epld
command as shown in either
(switches with Supervisor 2 or Supervisor 2E modules).
Example 8-15 Installing EPLD Images in Parallel for Switches with Supervisor 1 Modules
switch# install all epld bootflash:n7000-s1-epld.6.2.2.img parallel
Example 8-16 Installing EPLD Images in Parallel for Switches with Supervisor 2 or Supervisor 2E
switch# install all epld bootflash:n7000-s2-epld.6.2.2.img parallel

For Releases 6.1(1) and 6.1(2), if there are any powered down M2 Series I/O modules, use the

no poweroff module command to power up that module.

For Release 4.0(2) or earlier releases, if you updated the power management EPLD image, you must
Note
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: reset the power for the module
(physically remove the module and reinstall it--a module reload or just pressing the ejector buttons is not
sufficient for this reset requirement), or reset the entire switch (power cycle the switch).
