The Alcatel‑Lucent‑Nokia 3HE08423AARC01 (also designated IPUCBGZ1AA) is a high‑performance control processor module for the 7750 SR service router platform. This module serves as the central routing engine, handling all control plane functions including routing protocol processing, MPLS signaling, system management, and user configuration. It is a critical component for ensuring stable, scalable, and resilient network operation in carrier and enterprise environments.
The 3HE08423AARC01 is based on a multi‑core CPU architecture with hardware acceleration for routing table calculations and security functions. It provides ample memory for storing large BGP tables, MPLS forwarding information bases (FIBs), and system logs. The module supports up to two redundant units per chassis in an active‑standby configuration, offering sub‑second failover for uninterrupted service. It is compatible with 7750 SR‑7, SR‑12, and other chassis that accept the CPM slot.
