Appendix 8 Managing the Switch Hardware
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
Example 8-15
(switches with Supervisor 1 modules) or
Example 8-16
(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
Modules
switch#
install all epld bootflash:n7000-s2-epld.6.2.2.img
parallel
Example 8-17
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 (in this case for a switch with Supervisor
1 modules).
Example 8-17 Installing Supervisor and I/O Modules Plus Other Specific Modules (for Switches with
Supervisor 1 Modules)
switch#
install all epld bootflash:n7000-s1-epld.6.2.2.img
parallel module all fan-module
1
Note
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
.
switch#
no poweroff module
slot_number
Note
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 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).
