HYTOPTODEVICE 487649-B21 Compatible 0.5M 10G SFP+ Passive Twinax DAC Cable for HPE BladeSystem c-Class Infrastructure
Product Overview
HYTOPTODEVICE produces pin-to-pin OEM replacement DAC matching original HPE 487649-B21 specification, tailor-programmed with exclusive HPE factory EEPROM data for native plug-and-play deployment on HPE BladeSystem c-Class enclosure, ProLiant Gen8/Gen9/Gen10 rack servers and HPE FlexFabric switch modules without extra firmware upgrade or port alarm error.
This 0.5-meter passive SFP+ DAC complies fully with SFF-8431/SFF-8432 MSA & IEEE 10GBase-CU industry standard, adopting 30AWG high-shield pure copper twinax structure. As passive copper cabling solution, no built-in monitoring chip so DDM/DOM diagnostic function is unavailable, only basic EEPROM identification data stored for host device recognition. Ultra-low power draw below 0.1W and minimal signal latency make it ideal for ultra-short internal wiring inside HPE BladeSystem cabinet and dense enterprise server room rack layout.
All finished 487649-B21 equivalent cables pass full HPE hardware compatibility aging test before shipment. As professional HPE-compatible DAC manufacturer HYTOPTODEVICE supports bulk wholesale discount, private label OEM marking and optional alternative length (0.3M/1M/2M/3M) to satisfy data center upgrade & blade chassis interconnection demands.

Frequently Asked Questions About HYTOPTODEVICE Compatible SFP+DAC Cable
Q1: Can HYTOPTODEVICE 487649-B21 work plug-and-play on genuine HPE BladeSystem c-Class chassis?
A: Absolutely, preloaded exclusive HPE EEPROM enables hot-plug directly without firmware update or hardware incompatibility warning on all certified HPE blade platforms.
Q2: Does HYTOPTODEVICE passive 487649-B21 DAC support DDM/DOM real-time digital diagnostic monitoring?
A: No, passive twinax design excludes monitoring circuit & chip; only basic part number info stored in EEPROM, pick active DAC variant if real-time port monitoring is required.
Q3: What is fixed standard length of HPE 487649-B21 replacement DAC?
A: Standard factory spec is 0.5M for in-chassis ultra-short connection; HYTOPTODEVICE stocks alternative 0.3/1/2/3M DAC for various rack layout customization.
