What is a feature of an electronic programmable logic device upgrade on a Cisco MDS 9000 Series Switch?

An EPLD upgrade on a Cisco MDS 9000 Series Switch involves updating firmware for specific hardware components within a module. This process often requires the individual module undergoing the upgrade to reset or reload its hardware, causing a localized disruption only to that particular module's operation, while other modules in the chassis remain functional.

EPLD upgrades are generally module-specific and do not disrupt all modules in the chassis; their impact is isolated to the components being updated.

EPLD upgrades are hardware-specific firmware updates for I/O modules, not a system-wide software upgrade process that the standby supervisor module performs.

EPLD upgrades are typically disruptive to the specific module being updated, as they require a hardware reset for the new firmware to take effect, making them not nondisruptive on all modules.
