Public Relations

Responsibilities

Provide on-site system- and rack-level services during NPI and early production stages

Serve as the technical interface between customers and Accton engineering teams

Advanced rack-level diagnoses and troubleshooting

Perform deep-dive root-cause analysis on fully assembled server racks reported failure from customers

Isolate complex failures to specific subsystems (Motherboard, CPU/GPU, DIMM, PSU, or PCIe Fabric) using Linux-based diagnostic tools, IPMI/BMC logs, and serial console outputs

Troubleshoot network connectivity issues within the rack, covering ToR switches, optical transceivers, and DAC/AOC cabling integrity

Diagnoses and troubleshoots hardware issues from power and liquid cooling systems

Perform precise repairing process

Hands-on works including disassembly, hardware replacement, reassembly of failure switch and rack system

Cable management: ensure all power and data cables are routed properly

Configuration restoration: Flash BIOS/BMC firmware to specific versions and configure IP settings to match original customer requirements

Liquid cooling system: replacing cooling-related parts (e.g. piping, joints, and cold plate modules)

Perform functionality checks

Subsystem Interoperability Check: Verify end-to-end communication between repaired compute nodes, Top-of-Rack (ToR) switches, and management networks. Ensure replaced hardware is correctly recognized by cluster management software and interacts properly with Rack PDUs (power capping/monitoring)

Firmware & Stack Consistency: Validate that BIOS, BMC, OS, CPLD, and Driver versions strictly match the "Golden Image" or the compatibility matrix of the entire rack. Identify and resolve version mismatches that cause integration failures (e.g. NIC firmware conflicting with Switch OS)

Liquid cooling system functionalities: ensure the system can operate at designed cooling capabilities (i.e. temperature and fluid pressure)

Respond promptly to customer issues and provide timely technical support

Support and maintain Accton’s lab operations, including setup and functionality checks

Travel approximately 10–20% as required for customer support
