52X-EI-AC、S5720-52P-EI-AC.

An RPS1800 is a redundant power supply system that provides power redundancy for the connected

switches to ensure uninterrupted services. When the internal power supply of a switch fails, the RPS1800

provides power to the switch immediately, which improves system reliability. Figure 3-2 shows how to

connect an RPS1800 to a switch.

Figure 3-2 Connecting an RPS1800 to an switch

The RPS1800 provides 1+6 cold backup for the switch:

• The RPS1800 can connect to a maximum of six switches and ensures seamless failover for at most one

switch when the internal power supply of the switch fails.

• When the internal power supply of the switch powered by the RPS1800 recovers, the RPS1800

immediately restores to backup state.

• Among the 6 DC output ports, OUT1 has the highest priority, and the other 5 ports have the same priority.

When the RPS1800 connects to six switches, the switch connected to OUT1 preferentially receives power

from the RPS1800.

4 Product Characteristics and Advantages

Huawei S5720-EI series have the following characteristics.

Easy operation and maintenance

The S5720-EI models with power sockets on the front panel can be installed in a 300 mm deep cabinet

and maintained from the front panel. This simpliﬁes equipment O&M and allows more ﬂexible cabinet

deployment. The small-sized cabinets can be placed against a wall or back to back to save space in the

equipment room.

The S5720-EI allows management personnel to remotely switch on the SYS indicator on the front panel.

After conﬁguration commands are used, the SYS indicator quickly blinks within a certain period, helping the

management personnel locate the device in the equipment room quickly and efﬁciently.

The S5720-EI supports Super Virtual Fabric (SVF), which virtualizes the "Core/aggregation + Access switch

+ AP" structure into a logical device. The S5720-EI enables the simplest network management solution in

the industry. It allows plug-and-play access switches and APs. In addition, the S5720-EI supports service

conﬁguration templates. The templates are conﬁgured on core devices and automatically delivered to access

devices, enabling centralized control, simpliﬁed service conﬁguration, and ﬂexible conﬁguration modiﬁcation.

The S5720-EI functions as a client in an SVF system.

The S5720-EI supports Easy Operation, a solution that provides zero-touch deployment, replacement of

faulty devices without additional conﬁguration, USB-based deployment, batch conﬁguration, and batch

remote upgrade. The Easy Operation solution facilitates device deployment, upgrade, service provisioning,

and other management and maintenance operations, greatly reducing O&M costs. The S5720-EI can be

managed using Simple Network Management Protocol (SNMP) v1/v2c/v3, command line interface (CLI),

web-based network management system, or Secure Shell (SSH) V2.0. Additionally, it supports remote

network monitoring (RMON), multiple log hosts, port trafﬁc statistics collection, and network quality analysis,

which facilitate network optimization and reconstruction.

The S5720-EI supports Two-Way Active Measurement Protocol (TWAMP) to accurately check any IP link and

obtain the entire network's IP performance. This protocol eliminates the need of using a dedicated probe or

a proprietary protocol.

Multiple reliability mechanisms

The S5720-EI supports iStack. This technology can virtualize up to nine physical switches into one logical

switch. Member switches in a stack implement redundancy backup to improve device reliability and use

inter-device link aggregation to improve link reliability. iStack provides strong network expansion capability,

enables easy increase of ports, bandwidth, and processing capacity of a stack, and simpliﬁes conﬁguration

and management.

The S5720-EI is equipped with two removable power modules that can work in 1+1 redundancy backup

mode. Mixed installation of AC and DC power modules is supported, allowing for ﬂexible conﬁguration

of AC or DC power modules according to service requirements. The S5720-EI provides two removable fan

modules. The fan speed can be adjusted according to working temperatures of the device, improving device

reliability.

Huawei Enterprise Sx700 Series Switch Product

In addition to traditional STP, RSTP, and MSTP, the S5720-EI supports Huawei-developed Smart Ethernet

Protection (SEP) technology and the latest Ethernet Ring Protection Switching (ERPS) standard. SEP is a ring

protection protocol speciﬁc to the Ethernet link layer, and applies to various ring network topologies, such

as open ring topology, closed ring topology, and cascading ring topology. This protocol is reliable, easy

to maintain, and implements fast protection switching within 50 ms. ERPS is deﬁned in ITU-T G.8032. It

implements millisecond-level protection switching based on traditional Ethernet MAC and bridging functions.

The S5720-EI supports Smart Link and Virtual Router Redundancy Protocol (VRRP), which implement backup

of uplinks. One S5720-EI switch can connect to multiple aggregation switches through multiple links,

signiﬁcantly improving reliability of access devices.

In addition, the S5720-EI provides multiple connection fault detection mechanisms, including Ethernet OAM

(IEEE 802.3ah/802.1ag/ITU Y.1731) and Bidirectional Forwarding Detection (BFD).

Enhanced service processing capability and comprehensive security control mechanisms

The S5720-EI supports the multi-VPN-instance CE (MCE) function, which allows users in different VPNs to

connect. The switch supports large multi-instance routing tables to isolate users in different VPNs. Users in

multiple VPNs connect to a provider edge (PE) device through the same physical port on the switch, which

reduces the cost on VPN network deployment. The S5720-EI supports Multiprotocol Label Switching (MPLS)

L3VPN, MPLS L2VPN (VPWS\VPLS), MPLS-TE, and MPLS QoS. It is one of a few cost-effective MPLS-capable

ﬁxed switches.

The S5720-EI provides excellent quality of service (QoS) capabilities and supports queue scheduling and

congestion control algorithms. Additionally, it adopts innovative priority queuing and multi-level scheduling

mechanisms to implement ﬁne-grained scheduling of data ﬂows, meeting service quality requirements of

different user terminals and services.

With enhanced network admission control (NAC) functions, the S5720-EI supports 802.1x authentication,

MAC address authentication, Portal authentication, and hybrid authentication, and can dynamically delivery

user policies such as VLANs, QoS policies, and access control lists (ACL). It also supports user management

based on user groups. You can specify authentication-free IP network segments and enable redirection of

HTTP connection requests to realize fast deployment of clients. If clients do not support HTTP access, the

S5720-EI can trigger Portal authentication for the clients.

The S5720-EI provides a series of mechanisms to defend against DoS and user-targeted attacks. DoS attacks

are targeted at switches and include SYN ﬂood, Land, Smurf, and ICMP ﬂood attacks. User-targeted attacks

include bogus DHCP server attacks, IP/MAC address spooﬁng, DHCP request ﬂood, and change of the DHCP

CHADDR value.

The S5720-EI sets up and maintains a DHCP snooping binding table, and discards the packets that do not

match the table entries. You can specify DHCP snooping trusted and untrusted ports to ensure that users

connect only to the authorized DHCP server.

The S5720-EI supports strict ARP learning, which protects a network against ARP spooﬁng attacks to ensure

normal network access.
