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);

Queue scheduling: Supports two modes: “Weight Fair (8:4:2:1 weight)” and “Strict”. The default is Weight Fair to avoid low priority traffic from starving;

Industrial adaptation: Supports IEC 61850 QoS and can set GOOSE/SMV/PTP and other power automation protocol messages as high priority to ensure real-time performance.

3. Network isolation: VLAN configuration

(1) VLAN mode and type

Support type:

IEEE 802.1Q VLAN: Label based logical isolation, supporting three port types: Access (single VLAN without labels), Trunk (multi VLAN with labels), and Hybrid (removable egress labels);

Port type VLAN: VLAN is divided based on physical ports, with simple configuration but low flexibility. When enabled, IGMP Snooping will be automatically disabled;

Unaware VLAN: does not check VLAN tags, only transmits all tagged messages transparently, suitable for serial connection in other VLAN networks.

(2) Typical application examples

Scenario: Switch A connects devices A (VLAN5), B/C (VLAN2), D (VLAN3), and E (VLAN4), and is interconnected with switch B through Trunk port 3;

to configure:

Device A port is set to Access, PVID=5;

Set the B/C ports of the device to Trunk, PVID=2, and fixed VLAN (tagged)=3/4;

Set the interconnection port of the switch to Trunk and enable the GVRP protocol to automatically synchronize VLAN information;

Set the corresponding port of switch B to Access, and match PVIDs with VLAN2/3/4/5 to ensure normal cross switch VLAN communication.

4. Multicast filtering: reducing network storms

Core agreement:

IGMP Snooping (IP layer): Supports v1/v2/v3, and only forwards multicast traffic to ports that have joined the group by listening to IGMP report/query messages to avoid flooding;

GMRP (MAC layer): dynamically registers multicast addresses, suitable for devices that do not support IGMP;

Static multicast MAC: Manually add multicast addresses and port bindings, suitable for devices that only support multicast but do not have IGMP/GMRP.

Configuration points: After enabling IGMP Snooping globally, it needs to be enabled separately by VLAN; Support ‘Enhanced Mode’, only forwarding multicast to member ports to reduce redundant traffic.

5. Bandwidth management and security protection

(1) Bandwidth control

Broadcast storm protection: supports limiting port broadcast/multicast/unknown unicast traffic rates (such as 8M), and can temporarily disable ports when exceeded (default disable for 30 seconds);

Entrance/exit speed limit: Configure the entrance/exit speed according to the port (such as limiting it to 10% of the total bandwidth) to avoid single devices occupying too much bandwidth.

(2) Security protection

User authentication: Supports centralized authentication using TACACS+and Radius, replacing local accounts and suitable for large-scale networking;

Port access control:

Static Port Lock: Bind a specific MAC address to a port and only allow communication with that MAC address;

IEEE 802.1X: Based on the client authentication server (such as Radius) – authenticator (switch) architecture, unauthenticated devices cannot access;

ACL access control list (only supported by layer 3 switches): Filter packets based on IP/MAC address, protocol (TCP/UDP), and port number (such as denying access to 192.168.2.0/24 network segment 192.168.0.1).

6. Alarm and diagnosis: rapid fault location

(1) Auto Warning

Email Alert: Configure SMTP servers (such as enterprise email) and recipient addresses (up to 4), triggering events including switch cold start, port link disconnection, traffic overload, configuration changes, etc;

Relay alarm: supports 2-channel relay output, can be associated with key events such as power failure and Turbo Ring breakage, and trigger external sound and light alarms;

Test verification: After configuration, a test email can be sent to confirm that the alarm channel is normal.

(2) Diagnostic tools

Mirror Port: Copy the inbound/outbound/bidirectional traffic of a specified port (monitored port) to the mirror port, and connect packet capture tools (such as Wireshark) to analyze network issues;

Ping test: initiate Ping requests from the switch (not PC initiated) to detect the connectivity between the switch and the target IP;

LLDP protocol: automatically obtains neighbor device information (such as neighbor IP, port, model), supports MXview software to automatically generate network topology.

(3) Monitoring and Logging

Real time monitoring:

Switch level: View the total traffic of all ports, unicast/multicast/broadcast packet rates;

Port level: View the sending and receiving speed and error packet count of a single port;

SFP monitoring: Check the temperature, voltage, and light emitting and receiving power of the optical module (with an error of ± 3dBm);

Log management: Record events such as cold start, configuration changes, authentication failures, port disconnections, etc. It supports exporting log files or sending them to Syslog servers (up to 3 configured).

Professional modification field: Provide enhanced maintenance and improve reliability for high mileage or high-intensity use (such as towing, off-road) transmissions.

This kit belongs to the classic “Zip Valve” series of Sonnax. Please note that it is only compatible with 6R80 and 6R100 transmissions produced after 2015, and is not compatible with previous models such as 6R80 (2009-2014) and ZF6HP series (Gen1/Gen2). The valve body model must be confirmed through a dedicated identification guide before use.

Core functions and suite composition

（1） Core maintenance function

The kit is designed around the three core fault points of “pressure control”, “shift logic”, and “sealing performance” of the 6R80/6R100 valve body. Typical problems that can be solved include:

Abnormal pressure control: unstable, delayed or impacted shifting pressure caused by wear of the main pressure regulator;

Sealing failure: Oil leakage caused by aging of the sealing ring, leading to insufficient clutch oil supply and slipping;

Piston/spring fatigue: Decreased shifting quality caused by the elastic attenuation of the accumulator piston or spring (such as jerking, gear jumping);

Electromagnetic valve adaptation issues: Electromagnetic valve performance failures and fault codes (such as PCA, SSA soleoid related codes) caused by damaged or misaligned sealing rings of the solenoid valve.

（2） Core components of the kit

The kit is divided into component groups according to the installation order, and all parts are Sonnax original compatible parts. The key components are as follows (sorted by installation steps):

Installation steps, component categories, specific specifications and quantities, functional roles

1 pressure regulator sleeve (diameter. 629 “x length. 645”) to replace the original worn main pressure regulator sleeve and restore pressure control accuracy

2 sets of valve and sleeve combination (including valve and matching sleeve) repair the clearance between the valve core and sleeve of the clutch control pressure regulator to solve pressure leakage

3 Internal end plugs and sealing rings – Internal end plugs: 4 pieces

-O-ring: 11 (including 3 spare) seals the internal oil passage of the valve body to prevent oil from flowing into the chamber. The end plug needs to be installed with a “perforated surface facing outward”

4 large end plugs and sealing rings – Large end plugs: 4 pieces

-Large O-ring seals: 6 (including 2 spare) to seal the external large-sized oil passage interface of the valve body, suitable for installation in the lower half of the valve body

5 small end plugs and sealing rings -6 small end plugs

-Small O-ring seals: 9 (including 3 spare) to seal the small-sized oil passage interface outside the valve body, suitable for installation on the upper part of the valve body

6 accumulator pistons and springs – accumulator pistons: 6

-Matching springs: Replace 6 aging clutch accumulator pistons and springs to improve shift buffering performance and reduce impact

5 specifications of sealing rings for 7 solenoid valves (including spare):

-12 × 2mm: 4 pieces (1 spare)

-13.5 × 2mm: 4 pieces (1 spare)

-11 × 1.5mm: 8 pieces (2 spare)

-15.60 × 1.78mm: 1 piece

-12.95 × 1.69mm: 1 sealing requirement for different types of solenoid valves (such as SSA, SSB, SSE) to prevent oil leakage from the solenoid valve

8 Vacuum Testing Tools – Test Spring: 1 piece

-Test plug: 1 for vacuum testing after valve body repair, to check the sealing of the oil passage and the flexibility of valve action

Note: Some packaging pockets are designed for multiple models and may indicate other application information. Please refer to the “Installation Guide” in the kit for accuracy.

Key technical characteristics and installation requirements

（1） Technical adaptability

Accurate size matching

The kit components strictly follow the original specifications of the Ford 6R80/6R100 valve body, such as a pressure regulator sleeve diameter of. 629 “and length of. 645”, which are perfectly compatible with the original valve (diameter of. 645 “, critical mating surface of. 511”) to avoid pressure control failure caused by dimensional deviations. Special attention should be paid: the pressure regulator valve and sleeve cannot be interchanged across different models. Before installation, the dimensions must be confirmed with a caliper (refer to the table below):

Application model key dimensions (A: length/B: diameter/C: diameter)

6R80 (after 2015)/6R100 A=. 645 “, B=. 629”, C=. 511“

ZF6 Gen1 (including 6R80 2009-2014) A=. 645 “, B=. 629”, C=. 495“

ZF6 Gen2 A=.804″，B=.629″，C=.511″

Material reinforcement design

The core components (such as accumulator piston and seal ring) are made of Sonnax special wear-resistant materials: the piston is made of high-strength engineering plastics, which is oil resistant and anti-aging; The sealing ring is made of nitrile rubber or fluororubber material, suitable for transmission oil (Ford XT-6-QSP/Merck SP), and is not easily hardened or deformed after long-term use.

（2） Key installation requirements

Valve body model identification

Before installation, it is necessary to confirm the compatibility of the valve body through the following 3 steps to avoid misuse:

Casting identification: The casting number for the upper valve body of 6R80 (after 2015) is 9FL3P-7A092-BA/FL3P-7A092-AA, and the lower valve body is FL3P-7A101-AA, without D2 Passage Eliminated;

Electromagnetic valve identification: The electromagnetic valve connector is made of transparent material, and the nozzle color is black/brown (ordinary electromagnetic valve) or gray (SSE electromagnetic valve), and the surface of the electromagnetic valve has flow level markings (1-5);

Pressure regulator identification: The pressure regulator sleeve has a dedicated groove (refer to product figure 4), and the size should be consistent with the specifications of 6R80/6R100 in the table.

Installation specifications

Torque requirements: The connecting bolts between the valve body and the gearbox housing have a torque of 8Nm (71 in lb), the metal oil pan bolts have a torque of 14Nm (10 ft lb), and the output shaft flange nuts have a torque of 60Nm (44 ft lb). A torque wrench is required to ensure accuracy;

Installation of solenoid valve: If the old solenoid valve is reused, it needs to be installed back to its original position (TCM has learned its flow characteristics) and cannot be confused; The new solenoid valve needs to correspond to the “nozzle color position” (e.g. brown nozzle corresponds to SSA/SSC/TCC solenoid valve);

Vacuum testing: After installation, the built-in test spring and end plug of the kit must be used for vacuum testing to check the sealing of the oil passage (qualification standard: stable vacuum degree, no obvious leakage), otherwise it may cause the fault to recur after maintenance.

Postoperative calibration

After the repair is completed, it is necessary to reset the adaptive learning value (KAM) of the transmission. It is recommended to use a Ford specific diagnostic tool to perform this;

Complete 6 cycles of light throttle up and down shifting (after the oil temperature reaches 80 ℃) to allow TCM to relearn shifting parameters and ensure shifting quality;

The transmission fluid needs to be filled with Ford original XT-6-QSP or Mercon SP specifications, with a full filling of 9.5 quarts (9 liters) and maintenance filling of 4.2 quarts (4 liters). The oil level should be checked after the temperature reaches 88 ℃ (190 ℉) and the thermal control valve opens.

Fault diagnosis and additional repair suggestions

（1） Typical faults and kit compatibility

The kit can specifically solve the following faults of 6R80/6R100. If the fault exceeds the scope, additional specialized components need to be purchased:

Additional suggestions on the ability to solve typical fault kits

Shift shock/jerking can be solved (replace accumulator piston, pressure regulator). If the fault still exists, check the clutch clearance (must comply with OE specification 0.2-0.4mm)

Shift delay/no reverse gear can be solved (replace end plugs, sealing rings, repair oil passage leaks). Check the transmission oil pump pressure (must comply with 10Nm pump bolt torque)

The fault code of solenoid valve (such as P0868 low pressure) can be solved by replacing the sealing ring and pressure regulator of the solenoid valve. Use an ohmmeter to check the resistance of the solenoid valve (SSA/SSB=5.5 Ω, SSE=18 Ω)

TCC slip/lock abnormality can be resolved (replace TCC related sealing rings, bypass clutch adjuster). Check the wear of the torque converter and replace it if necessary

（2） Key wear areas and testing

The technical manual accompanying the kit specifies in detail the wear areas of the valve body that need to be inspected in detail. It is recommended to verify through vacuum testing:

Lower valve body: main pressure regulator valve, clutch A/E control regulator valve, solenoid valve pressure regulator valve. If the vacuum degree is insufficient (such as below 50% of the standard value), an additional Sonnax oversize valve kit (such as 95740-46K main pressure valve kit) needs to be purchased;

Upper valve body: accumulator piston (sealing in inverted state needs to be tested), clutch B/D control valve. If the piston sinks more than 0.030 “, the reinforced piston needs to be replaced (the kit includes the basic version, and the high-strength version needs to be ordered separately).
