An HPE FlexFabric 5950 48SFP28 8QSFP28 (JH402A) always downgrades an HPE JH419A 100G QSFP28 LC SWDM4 transceiver to 40G and never brings it up at full speed. Why?
Standing up a small traffic-test bench next to the production fabric, and the tester ports will not come up over copper at all. HP 5900 40G switch, JC772A HP JG328A 40G QSFP+ direct attach cable Ixia Xcellon-Multis QSFP 40/10GE load module Spirent TestCenter 40G module, tried as a second opinion HP…
Second hand HPE 5130 for the rack at home, and it arrived with four HPE JD092B X130 10G SFP+ SR modules in the box. I bought new OM4 LC patch cords, wired one SFP+ port to the 10G card in the server, and got absolutely nothing. HPE FlexNetwork 5130 24G PoE+ 4SFP+ EI (JG936A) 4x HPE JD092B X130 10G…
On an HPE 5510 24G SFP 4SFP+ HI (JH149A, Comware 7.1.045 R1111P01) genuien JD119B and JD118B 1G SFPs were accepted at first (OPTMOD/4/MODULEIN: The transceiver is 1000BASESXSFP), but after a cold power reboot the same modules were reported as UNKNOWNSFPPLUS with OPTMOD/5/CHKSUMERR: Transceiver…
An HP 5900AF-48XG-4QSFP+ (Comware 7.1.045 R2311P01) logged OPTMOD/4/PHONYMODULE: This is not a supported transceiver for this platform for two 10G SR SFP+ modules; display transceiver interface identified them as Avago and JDSU 10GBASESRSFP with DDM. The poster wanted to know which SFP+ to buy and…
The poster asked whether third-party optics can be used in an HPE FlexFabric 5700 40XG 2QSFP+ (JG896A) and whether the ProVision command allow-unsupported-transceiver exists on it. The answer clarified how Comware differs from ProVision: there is no allow-list of supported transceivers, so unlisted…
A FlexFabric 5900AF running Comware 7.1.035 R2208P01 reported a third-party transceiver as not supported when inserted, while the same class of modules worked in a FlexFabric 7904 on 7.1.045. The poster asked whether support could be enabled by command and whether the Comware versin mattered…
H3C-SFP-10G-T-SO 10GBASE-T copper modules (from FS or Solid Optics) worked out of the box in a FlexFabric 5940 (JH398A) with the JH181A 24-port SFP+ card, but in a FlexFabric 5945 (JQ076A) with the same card the ports only came up after manually running port up-mode on the interface. The poster…
Even with allow-unsupportted-transceiver enabled, HPE Aruba 3810M and 2930M switches showed an amber fault for generic SFP+ modules, including ones recoded to masquerade as a J9151A. The author traced the behaviour to HPE's HPIDv2 challenge-response authentication: the module EEPROM carries a flag…
The poster tried to link an HPE FlexFabric 5900AF and a Dell S5212F-ON at 10 Gbps with DAC cables that had been custom-made with an HPE-coded end and a Dell-coded end. Both ports were forced to 10G full duplex, but no link came up. On the HPE side the interface reported Media type is stack wire…
An HPE 2920 (J9729A, firmware WB.15.17.0009) with the J9731A 10G expansion module was connected to a DL380 Gen8 with a 560SFP+ NIC using a genuine HPE X242 3 m SFP+ DAC (J9283B). Port A1 with a J9150A SR module worked, but port A2 with the DAC logged Transceiver type not supported in this port and…
The poster wanted to verify whether an HPE StorageWorks 81B 8 Gb Fibre Channel HBA (AP769-60001) fitted with an AJ716B SFP could be used in an HPE ProLiant DL380 Gen10 server (P02464-B21) and asked for a tool where part numbers can be entered to get a compatibility verdict. No error had occurred…
