RFQ
> Q1: What is included in the base package of part number CR5P03BASD75?
A: The CR5P03BASD75 bundle includes the NE40E-X3A 4U host chassis, 2 Main Processing Units (MPUs) for 1+1 control plane redundancy, and 2 DC Power Supply Modules. Please note that Line Processing Cards (LPUs), optical transceivers, and specialized software feature licenses (such as advanced CGN or specific IPsec packages) are sold separately based on your network topology requirements.
> Q2: Can the Huawei NE40E-X3A support 100G SFP28/QSFP28 and legacy POS optical modules simultaneously?
A: Yes. The modular LPU architecture of the NE40E-X3A allows network operators to populate slots with mixed interface cards. You can run 100GE QSFP28 line cards (CR57LAXFA70) alongside legacy POS (OC-192c/STM-64c to OC-3c) or 10GE SFP+ cards (CR5D00L1X7) in the same chassis, making it ideal for migrating legacy SDH/SONET transport networks to pure IP/MPLS.
> Q3: How does the NE40E-X3A ensure zero packet loss during MPU switchover or software updates?
A: The NE40E-X3A features full Non-Stop Routing (NSR), Non-Stop Forwarding (NSF), and Graceful Restart (GR) protocols combined with hardware-level 1+1 MPU switchover. Control plane state tables are synchronized continuously between the active and standby MPUs. Furthermore, in-service software updates (ISSU) allow system firmware to be upgraded without interrupting line-rate traffic on the LPUs.
> Q4: What is the warranty coverage and global technical support model for this router?
A: All new Huawei NE40E-X3A hardware components come with a standard 1-Year Hardware Return-to-Factory Warranty. For mission-critical ISP and enterprise environments, optional Huawei Hi-Care Contracts can be attached, offering 24/7 Global Technical Assistance Center (TAC) hotline support, immediate software patch rights, and Next Business Day (NBD) or 4-Hour On-Site Advanced Spare Replacement.
