The EDS-528E standalone, compact 28-port managed Ethernet switches have 4 combo Gigabit ports with built-in RJ45 or SFP slots for Gigabit fiber-optic communication. The 24 fast Ethernet ports have a variety of copper and fiber port combinations that give the EDS-528E Series greater flexibility for designing your network and application. The Ethernet redundancy technologies, Turbo Ring, Turbo Chain, RSTP/STP, and MSTP, increase the system reliability and availability of your network backbone. The EDS-528E also supports advanced management and security features.

Moxa EDS-528E Series is designed specifically for critical industrial environments with limited installation space and high protection level requirements, such as maritime, rail wayside, oil and gas, factory automation, and process automation.

Communication Connections
Each EDS-528E switch has 4 types of communication ports:
• 1 USB console port (type B connector)
• 1 USB storage port (type A connector)
• 24 10/100BaseTX Ethernet ports
• 4 Gigabit Ethernet combo ports: 4 10/100/1000BaseT(X) and 4 100/1000BaseSFP ports

Loop Protection
The switch is designed with a loop checking mechanism whereby it sends a control BPDU from the Ethernet port and check if this control PBDU will be sent back to the switch again. If the looping occurs, the switch will automatically block the Ethernet port to prevent looping

User Account
Moxa EDS 528 switch supports the management of accounts, including establishing, activating, modifying, disabling, and removing accounts. There are two levels of configuration access: admin and user. Accounts with admin authority have read/write access of all configuration parameters, whereas accounts with user authority only have read access to view configuration items.

Security features based on IEC 62443-4-2
Security can be categorized into two levels: the user name/password level, and the port access level. Moxa switches provide many kinds of security functions, including Management Interface, Trusted Access, SSL/SSH Authentication certificate, Login Authentication, IEEE 802.1X, MAC Authentication Bypass, Port Security, Broadcast Storm Protection, Loop Protection, and Access Control List.

Moxa switches provide a Port Security function that lets packets with allowed MAC Addresses access the switch’s ports. Two Port Security modes are supported: Static Port Lock and MAC Address Sticky. 

Moxa ACLs can manage filter criteria for a diverse range of protocols and allow users to configure customized filter criteria. Each ACL includes up to 10 rules. 

Login Authentication
Moxa managed switches provide three different user login authentications: TACACS+ (Terminal Access Controller Access-Control System Plus), RADIUS (Remote Authentication Dial In User Service), and Local. The TACACS+ and RADIUS mechanisms are centralized “AAA” (Authentication, Authorization and Accounting) systems for connecting to network services. The fundamental purpose of both TACACS+ and RADIUS is to provide an efficient and secure mechanism for user account management

Diagnostics
Moxa EDS 528E switch provides three important tools for administrators to diagnose network systems: LLDP, Ping, and Port Mirror.

Enabling the LLDP function allows Moxa’s MXview to automatically display the network’s topology and system setup details, such as VLAN and Trunking for the entire network. The Ping function uses the ping command to give users a simple but powerful tool for troubleshooting network problems. 

The Port Mirroring function can be used to monitor data being transmitted through a specific port. This is done by setting up other port(s) (the mirror port) to receive the same data being transmitted from, or both to and from, the port under observation. Using a mirror port allows the network administrator to sniff the observed port to keep tabs on network activity
