Moxa EDS-508A series network managed Ethernet switch
Initialization configuration: three management interface operations
EDS-508A supports three initial configuration methods: serial port console, Telnet console, and web browser. Please note that the default IP address is 192.168.127.253, subnet mask is 255.255.255.0, and the PC needs to be on the same logical subnet as the switch to access through the network interface.
1. Serial console configuration (preferred when no IP)
Hardware connection: Connect the console port of the switch to the COM port of the PC using an RJ45 to DB9 cable;
Parameter settings: baud rate 115200, no checksum (None), data bit 8, stop bit 1, terminal type VT100 (recommended to use Moxa PComm Terminal Simulator software);
Login process: Select terminal type 1 (ansi/vt100), login account as admin (read-write permission) or user (read-only permission), default no password, can be set as needed (maximum 16 characters).
2. Telnet Console Configuration
Prerequisite: The PC and switch are on the same subnet, and physical connections can be made using either direct or crossover Ethernet cables;
Operation steps: Enter telnet 192.168.127.253 through Windows' Run ', and the subsequent terminal type selection and login process should be consistent with the serial port console;
Attention: Check "VT100 Arrows" in the terminal preference settings to ensure proper cursor navigation.
3. Web browser configuration (easiest to use)
Access method: Enter the switch IP (such as 192.168.127.253) in the browser address bar, and log in with the admin/user account;
Interface features: The left navigation bar categorizes and displays all configuration items, supports visual operations, and is suitable for non professional technicians to quickly get started;
Security advice: If remote management is not required, Telnet and web access can be disabled through the serial port console to reduce security risks.
Detailed Explanation of Core Function Configuration
1. Basic settings: System and network parameters
(1) System Identification and Security
System information: The switch name (such as "Factory Line 1 Switch"), location, and contact information of the maintenance personnel can be configured. The information will be displayed at the top of the web console and in the alarm email;
Password management: The admin account has full permissions, while the user account only has read-only permissions and supports password modification (requires repeated input confirmation, can clear password and restore default);
IP access control: Use the 'Accessible IP List' to restrict access to the switch to only specified IPs or subnets (such as allowing only 192.168.1.0/255.255.255.0 network segments), and allow all IPs to access when not enabled.
(2) Ports and network parameters
Port settings: Configure port enable/disable, transmission rate (auto negotiate or fixed 10M/100M full/half duplex), flow control (FDX Flow Ctrl), MDI/MDIX mode (default auto detect);
Network configuration:
IPv4: supports manual setting of IP, subnet mask, gateway, or automatic acquisition through DHCP/BootP;
IPv6: Supports link local address (automatically generated) and global unicast address (requires prefix configuration);
DNS: Primary and backup DNS servers can be set up, supporting access to switches through domain names (DNS needs to be configured first).
(3) Time management
Time synchronization: Supports NTP/SNTP clients, configurable primary and backup time servers (such as time. nist. gov), with a default query cycle of 600 seconds;
Time zone and daylight saving time: The default GMT time zone allows for manual setting of daylight saving time start/end dates and time offsets;
Attention: Models without real-time clock (such as EDS-508A) require time synchronization after restart. It is recommended to configure NTP server for automatic calibration.
2. Network reliability: redundancy and traffic control
(1) Turbo Ring Redundancy (Industrial Scene Core)
Enabling method: Through the top DIP switch (switch 4) or software configuration, Turbo Ring v2 protocol is supported by default, with recovery time< 20ms@250 Switch;
Attention: If VLAN or port aggregation needs to be enabled on the last 4 ports, Turbo Ring cannot be activated through DIP switches and must be configured through software.
(2) Port Trunking
Function: Bind multiple ports into an aggregation group (up to 4 groups, with a maximum of 8 ports per group), increase bandwidth (e.g. aggregate 8 100BaseTX full duplex ports to achieve a bandwidth of 1.6Gbps), and achieve redundancy;
Mode selection: Supports static aggregation (Moxa private protocol) and LACP (IEEE 802.3ad standard). After configuration, the VLAN, multicast filtering, and other settings of the port will be reset to default;
Applicable models: EDS-508A supports 2 aggregation groups, with different numbers of aggregation groups for different models (e.g. EDS-518A supports 3, EDS-728 supports 4).
(3) Traffic Priority (QoS)
Core mechanism: Based on IEEE 802.1p (Layer 2) and TOS/DiffServ (Layer 3) labels, traffic is divided into four priority queues (high/medium/normal/low);
