Configuring EPLDs
Deciding When to Upgrade EPLDs
You do not always need to upgrade EPLD images but the following circumstances do require that you
upgrade these images:
• If you are upgrading Supervisor 1 modules with Supervisor 2 or Supervisor 2E modules and the
switch has Fabric 2 modules (you must upgrade at least the Fabric 2 EPLDs)
• If you are enabling software features (LIST, VPCs, and so on) that require EPLDs
• If you are using M2 Series 100-Gbps Ethernet I/O modules that remain powered down after booting
up the switch
When new EPLD images are available, the upgrades are always recommended if your network
environment allows for a maintenance period in which some level of traffic disruption is acceptable. If
such a disruption is not acceptable at this time, you might consider postponing the upgrade until a better
time.
Note The EPLD upgrade operation is a disruptive operation. You should execute this operation only at a
programmed maintenance time. The system/kickstart ISSU upgrade is a nondisruptive upgrade.
Note Do not perform an EPLD upgrade during an ISSU system/kickstart upgrade.
Table 8-8 provides high-level guidelines to help network administrators determine whether an EPLD
upgrade is necessary when upgrading Cisco NX-OS Release 5.0(1) or a later release. If you are
upgrading an earlier release, see one of the following earlier versions of the release notes:
• Cisco Nexus 7000 Series FPGA/EPLD Upgrade Release Notes, Release 4.0
• Cisco Nexus 7000 Series FPGA/EPLD Upgrade Release Notes, Release 4.1

M2 Series I/O modules remain powered down
after booting up the switch for Cisco NX-OS
Release 6.1(1) or 6.1(2).
Download one of the following EPLD images and
use the no poweroff module command for each
powered down M2 Series I/O module:
• For Release 6.1(1) and supervisor 1 modules
download n7000-s1-epld.6.1.1a.img.
• For Release 6.1(1) and supervisor 2 modules
download n7000-s2-epld.6.1.1a.img.
• For Release 6.1(2) and supervisor 1 modules
download n7000-s1-epld.6.1.2a.img.
• For Release 6.1(2) and supervisor 2 modules
download n7000-s2-epld.6.1.2a.img.
Upgrading the Cisco NX-OS operating system
from Release 4.x to Release 5.0 or later releases.
Update all supervisor, I/O, and fabric modules
with the latest EPLD images.
