Exxact TS4 Server

Overview

TS4-194492555 is an Exxact TensorEX multi-GPU server platform that appears here in dense research and HPC deployments, often configured with dual AMD EPYC CPUs and up to 8 GPUs. The tickets show it as a high-complexity system where failures often involve the barebone, motherboard, PCIe path, fan-control hardware, storage boot media, or deployment-specific configuration questions rather than simple single-part swaps.

Known Issues

• Motherboard Hardware Failure , 4 tickets
  Multiple RMAs ended with the motherboard or barebone identified as the true cause of no-POST, no-power, or early-shutdown behavior. Representative tickets: #29660, #30848, #36219, #40733.
• PCIE Riser Failure , 3 tickets
  This platform shows recurring PCIe-path problems affecting GPUs, NICs, or NVMe devices, including bad transfer cables, slot faults, and broken riser power path hardware. Representative tickets: #33918, #34056, #36219.
• Defective Storage Drives , 1 ticket
  One TS4-194492555 deployment lost its NVMe OS drive entirely, leaving the system without a bootable Ubuntu install. Representative ticket: #31443.
• Fan Speed Issues , 2 tickets
  Fan-controller and fan-profile questions show up both in live support and depot repair, including six-fan non-spinning events and custom profile needs for FPGA airflow. Representative tickets: #32471, #5871.
• System Boot Failure , 5 tickets
  Several tickets start from the customer-visible symptom of no POST, spontaneous reboot, or power-on failure before depot work isolates the underlying board or PCIe cause. Representative tickets: #29660, #30848, #34056, #36219, #40733.

Common Questions

• Does TS4-194492555 support an add-in RAID card?
  Yes, at least in principle. Ticket #5562 says Exxact confirmed the platform should support an add-in RAID card and then routed the purchase request to Sales, though the ticket did not preserve a specific compatible SKU.
• Should SMT or multi-threading be enabled by default on dual-EPYC builds?
  Yes. In #5824, support confirmed SMT should have been enabled and gave BIOS steps to restore the expected 256-thread view on 2x 64-core Milan systems.
• Can the platform be tuned for nonstandard accelerator airflow, like FPGA cards?
  Yes, but the workflow may require manual fan-profile work and board-manual references. Ticket #5871 shows Exxact helping a customer tune fan behavior for an 8x DWFL FPGA deployment.
• If NVMe, NIC, or one GPU path disappears, is the board always bad?
  Not necessarily. #33918 ultimately traced missing NIC and NVMe devices to a bad transfer cable and lane configuration, while #34056 and #36219 involved deeper PCIe or riser-side hardware faults.
• How hard is full-system RMA on this platform?
  Logistics can be significant. Multiple tickets show pallet or box sourcing, freight coordination, and delays around packaging before the system could be returned (#29660, #30848, #32471, #40733).
• Can the same chassis family surface both boot and thermal-control issues?
  Yes. The evidence spans boot failure, PCIe faults, NVMe loss, network instability, and fan-controller or fan-profile concerns on the same TS4-194492555 family (#31443, #32471, #36219, #5871).

Related Products

• GIG-G482-Z54-00 / GIG-G482-Z54 barebone , this is the barebone repeatedly named underneath TS4-194492555 RMAs, especially in motherboard and fan-board failures (#29660, #32471, #40733).
• 8x RTX A5000 TS4-194492555 configurations , several tickets reference this exact pairing, making GPU-path and NVMe-path faults easy to confuse with bad cards when the platform path is actually at fault (#31443, #34056).
• Other TensorEX multi-GPU systems with freight-only service needs , this model repeatedly appears in environments where return packaging, pallet handling, and on-campus receiving coordination are part of support, which can distinguish it operationally from smaller workstation-class products (#29660, #30848, #32471, #36219).
