The Cisco NCS 5064 chassis, which is also an extension to Cisco's routing platform portfolio enabling Service Providers and MPLS enabled data center architectures to offer elastic networks with improved business agility and simplified operations to deliver high-bandwidth mobile, video, and cloud services.

The Cisco NCS 5064 chassis is a small form factor dense 100GE aggregation systems in 2RU form factor. Powered by industry leading routing operation system, IOS-XR, the system also offers rich functions such as third party application hosting, machine-to-machine interface, telemetry and flexible package delivery.

  • Two hot-swappable power supply (PSUs) that support 1+1 redundancy under most conditions. Only when the 930W DC supplies (NC5K-PDC-930W-FR and NC5K-PDC-930W-BK) are used, both the PSUs must be inserted and operational in a non-redundant 2+0 mode.

  • Different power supply units (PSUs) are available for different air flow configurations.

  • Three hot-swappable fan modules that provide port side intake or port side exhaust cooling in 2+1 redundancy mode.

Upgrading Cisco IOS XR Software

Cisco IOS XR Software is installed and activated from modular packages, allowing specific features or software patches to be installed, upgraded, or downgraded without affecting unrelated processes. Software packages can be upgraded or downgraded on all supported card types, or on a single card (node).

Before starting the software upgrade, use the show install health command in the admin mode. This command validates if the statuses of all relevant parameters of the system are ready for the software upgrade without interrupting the system.

The upgrade document is available along with the software images.

Cisco Software Manager (CSM) application provides an intuitive user interface to manage Cisco IOS XR installations, with pre-installation and post-installation checks and reports. CSM helps manage the process of software maintenance upgrades (SMUs) and service packs (SPs) on devices that run the Cisco IOS XR Software.

For information on how to use CSM, see Cisco Software Manager User Guide.
