Server-grade signal extension
The Innocard EP4101 converts a PCIe x4 Gen 5 link into an MCIO 38P interface and includes a 50 cm cable to a U.3 (SFF‑8639) connector. It targets integrators who need to route high‑speed storage or accelerator signals beyond the motherboard edge while retaining out‑of‑band management. Built‑in ReDriver, clock buffer and SMBus circuitry preserve link integrity across the extended path.
Sustained 32 GT/s operation
An on‑board ReDriver supplies up to 24 dB equalisation at 16 GHz, keeping the 32 GT/s differential pairs stable over the full cable length. A 100 MHz clock buffer drives longer traces without drift, and PERST#, WAKE# and CLKREQ# translators maintain out‑of‑band control during continuous heavy I/O. Green LEDs report link ready, wake and clock‑request status in real time.
Taiwanese build with protection
Designed and made in Taiwan, the adapter uses 30 µ gold MCIO connectors and a 3.3 V input with bidirectional TVS diodes, a 3 A load switch and reverse‑current protection. SMBus switch (0x71) and I/O expander (0x20) handle power‑disable and reset remotely. The half‑height AIC form factor fits standard server slots for permanent rack deployment.

Questions about this item
How much heat does the EP4101 generate when running continuously at 32 GT/s?
The EP4101 draws 3.3 V at up to 3 A with a built-in load switch and reverse-current protection; the integrated ReDriver equalises up to 24 dB at 16 GHz to maintain signal integrity without active cooling.
What host slot and drive connector must I already have to use this EP4101 kit?
You need a free PCIe x4 Gen 5 add-in-card slot for the MCIO 38P AIC and a U.3 (SFF-8639) drive bay; the 50 cm cable connects the two via SFF-TA-1016 interfaces.
