Huawei NE40E-X3A (CR5P03BASA75) – 3 LPU Slots, 1.08 Tbps Core Router

Q1: Is the chassis and line cards sold separately?

A: Yes. The NE40E is a chassis-based router; the main chassis (X3A, X8A, etc.) is sold separately from line cards and modules. You select and install line cards based on your interface and bandwidth needs.

Q2: Are key components hot-swappable?

A: Yes. The NE40E supports hot-swappable power modules, fan trays, line cards, and switch fabric units—allowing replacements without system downtime.

Q3: Does the NE40E support redundancy at component level?

A: Yes. It includes redundancy for route processors (MPUs), switch fabrics (SFUs), and fans/power. Redundant components automatically take over if one fails .

Q4: Can the router perform non-stop upgrades?

A: Yes. The NE40E supports Non-Stop Routing (NSR), Non-Stop Forwarding (NSF), Graceful Restart (GR), and In-Service Software Upgrades (ISSU) .

Q5: What density and backplane capacity does it offer?

A: It supports up to 1 Tb/s per slot line cards and overall system capacity up to 50 Tb/s depending on model (e.g., X8A). Thus, it scales with service demands .

Q6: Which routing and switching features are supported?

A: Protocol support includes IPv4/IPv6 routing (BGP, OSPF, IS-IS), MPLS, L2/L3VPN, QoS, multicast, and hardware‑accelerated forwarding via NP chips .

Q7: What high-availability mechanisms are provided?

A: In addition to hardware redundancy, it supports IP/LDP/VPN FRR, VRRP, Ring Protection, BFD, Ethernet OAM, and more, enabling < 200 ms failover .

Q8: Can the system run IPv6 and IPv4 in parallel?

A: Yes. NE40E supports dual-stack, IPv6 tunnels, 6PE, IPv6 VPNs, and IPv4-to-IPv6 transition mechanisms .

Q9: What management interfaces are available?

A: Management options include RJ‑45 console, in-band (Ethernet) and out-of-band management, SSH, SNMP, NETCONF, web GUI, CLI, and logging .

Q10: Does the chassis support environmentally friendly design?

A: Yes. It includes energy‑saving NP chips, dynamic fan control, and complies with RoHS, WEEE, REACH and EU eco‑design directives .

Q11: What environmental and physical specifications does it meet?

A: Operational temperature: 0–45 °C (up to 55 °C short‑term), humidity 5–85% RH, altitude up to 3000 m. Mounts in standard 19" racks with ~800 mm depth .

Q12: Which SDN and OAM features are included?

A: Supports SDN protocols, AtomEngine, OpenFlow, VxLAN, IP-FPM, TWAMP, Y.1731, 802.1ag OPER, RFC tools, and advanced fault monitoring .

Q13: What security mechanisms are available?

A: Device security via MPAC, URPF, GTSM; service-level ACLs, IPSec, keychain authentication, DHCP snooping, TCP/IP defense, DoS protections, BGP Flowspec, SSH v2 etc. .

Q14: How about virtualization support?

A: Virtual System (VS) technology allows partitioning of hardware to multiple logical routers, with resources isolated between them .

Q15: Does it support flexible QoS?

A: Yes. Supports five-level hierarchical QoS, sophisticated traffic classification, policing, shaping, WRED, MPLS QoS, bandwidth constraint models etc. .

Q16: Can line cards be powered on/off individually?

A: Yes. You can hot‑power on or off line cards using CLI commands without affecting the rest of the chassis .
