The HPE Networking Comware Switch Series 5550 HI is a family of stackable L3 access and aggregation switches powered by Comware delivering the performance, resiliency and flexibility for medium and large enterprise.

Equipped with 36 and 48 MACsec-256 enabled 1G copper, fiber and combo ports, 4 built in 10/25G SFP28 uplinks, dual hot swappable power supply and fan trays, the 5550 HI also has one built-in expansion slots for the cross platform network modules used in the Comware 5000 series. The platform supports high density 90W PoE (802.3bt) per port, high performance IP routing and MPLS. Intelligent Resilient Fabric (IRF) stacking up to 9 members adds scale and high availability while Intelligent Network Quality Analyzer (iNQA) supports real-time visibility into network health and performance.

In addition HPE IMC for centralized management, the 5550 HI comes with the built-in embedded management system SmartMC for configuration, visibility and monitoring at no additional cost. |

What's new

  • Improved hardware specification and scale: faster CPU, increased memory, up to 744 Gpbs bandwidth, 128K MAC table, improved ARP, ACL, IPv4/v6 unicast and multicast and MPLS LSP scale.
  • Diverse I/O options and upgraded uplinks: Flexible I/O 36 and 48 port copper, fiber and combo GE ports downlink, and expanded uplink ports 8x25G and 2x100G via the expansion model.
  • Enhanced security with all ports MacSec AES-256.
  • L3 multicast support.
  • High Densify PoE++: up to 48 port 90W PoE++/port.
  • Support containerizaton for application hosting. |

Features | Scalable, High-Performance L3 Access Switches

The HPE Networking Comware Switch Series 5550 HI provides medium and large enterprise networks with faster CPU, increased memory, flash and packet buffer, up to 744 Gpbs bandwidth, 128K MAC table, improved ARP, ACL, IPv4/v6 unicast and multicast scale, and MPLS LSP scale.

Improved non-blocking bandwidth and throughput: 744 Gbps of switching capacity and 553 Mpps of forwarding for powerful performance. Scales up to 9 members with Intelligent Resilient Fabric (IRF) stacking.

Expanded the uplink speed to 2x100G via expansion modules.

Improved MPLS LSP scale, comprehensive MPLS support (L3 MPLS VPN, VPLS, EoMPLS, MPLSoGRE) for use as MPLS CE, VXLAN and EVPN.

Support containerization for application hosting.

Resilient and Highly Available Access Networking

The HPE Networking Comware Switch Series 5550 HI uses Intelligent Resilient Framework (IRF) that supports virtualization of up to 9 physical switches into one logical device for simpler, flatter, and more agile networks.

Delivers outstanding resiliency, security, and multiservice support capabilities for traditional large enterprise networks. It supports advanced technologies such as OAM, RRPP, BFD, Multi-level QoS, MPLS, and VPLS.

Dual, redundant, hot-swappable power supplies maintain a dynamic network that delivers up to 2870 watts of industry standard 802.3bt PoE for powered cameras, phones, and wireless access points.
