Cisco 1004 Xponder 400GE Upgrade to TXP Mode License | NCS 1K4 — E-NCS1K4-400GUPGL=

Move 400GE capability into TXP mode with a Cisco e-delivery license built for the NCS 1K4 platform. This entitlement is intended for network teams that need a controlled licensing step when changing operational mode, rather than replacing hardware or overbuying capacity. It supports disciplined network planning where transport configuration, service activation, and upgrade governance must stay aligned. For infrastructure organizations, the appeal is precision. A mode-specific license helps keep upgrades tied to the exact platform behavior required by the deployment, which can simplify change management and reduce ambiguity during rollout. E-delivery also fits procurement workflows that prefer digital fulfillment and faster entitlement handling. This is the kind of license that makes sense when the platform is already in place and the goal is to unlock a specific operational mode. Compared with broader upgrade packages, it gives teams a narrower, more controlled path for capacity transition on Cisco NCS 1K4 systems.
