Chapter 7 Managing the Switch Hardware
Configuring EPLDs
Note A module reload or just pressing the ejector buttons on the module is not sufficient for this
reset requirement.
• To reset the entire switch, power cycle the switch.
Caution Resetting the power disrupts any data traffic going through the affected modules. If you power cycle the
entire switch, all data traffic going through the switch at the time of the power cycling is disrupted. This
is not necessary for Release 4.0(3) or later releases.
Note For Release 4.0(3) and later releases, the switch automatically loads the new power management EPLD
after an upgrade, so it is no longer necessary to reset the power for the module or switch.
To confirm the EPLD upgrades, see the “Verifying the EPLD Upgrades” section on page 7-47.
Verifying the EPLD Upgrades
You can verify the EPLD upgrades for each slot in the switch by using the commands listed in
Table 7-14.
This example shows how to verify the EPLD images for the Cisco Nexus 7018 supervisor module in
slot 9:
switch# show version module 9 epld
This example shows how to verify the EPLD images for the fan-tray module in fan-tray module slot 2:
switch# show version fan 2 epld
This example shows how to verify the EPLD images for the fabric module in fabric module slot 4:
switch# show version xbar 4 epld
Displaying the Available EPLD Versions
To view the available EPLD versions, use the show version epld url command as shown in
Example 7-13.
