Chapter 7 Managing the Switch Hardware
Configuring EPLDs
If you need to know which modules can be updated and which upgrades are disruptive to switch
operations, see the “Determining Whether to Upgrade EPLD Images” section on page 7-40.
To upgrade the EPLD images for a Cisco Nexus 7000 Series switch, you use one of the install
commands listed in Table 7-13. These commands enable you to upgrade the EPLD images for all of the
modules on the switch, multiple modules of one or two types, or single modules. When specifying a
slot_number, use one number. When specifying slot_numbers, you can specify all for all slots, multiple
slots separated by commas (x,y,z) or a range of slot numbers (x-y).
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.
When you upgrade supervisor module in a single-supervisor switch, the operation is disruptive to switch
operations if the switch is active.
This example shows how to start the installation of all new EPLD images for all modules in a switch:
switch# install all epld bootflash:n7000-s1-epld.6.0.1.img parallel
This example shows how to start the installation of all new EPLD images for all of the I/O and supervisor
modules and the fan-tray module in fan-tray slot 1:
switch# install all epld bootflash:n7000-s1-epld.6.0.1.img parallel module all
fan-module 1
For Release 4.0(2) or earlier releases, if you updated the power management EPLD image, you must
reset the power for the module so that EPLD can take effect (this action is not required for Release 4.0(3)
or later releases). 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.
