DAC Cable to HP 2920

[Robbie-w]

Hello,

Is there a DAC cable to go from HP 2920(with SFP+ expansion module) to HP A5800(JC103a)

I know it never used to be supported but was something HP was working on

Thanks

Robbie

Probably (read this) you should go with one of these (see QuickSpecs) to fulfill requirements [*] on the Aruba side:

• HPE X242 10G SFP+ to SFP+ 1m Direct Attach Copper Cable J9281B
• HPE X242 10G SFP+ to SFP+ 3m Direct Attach Copper Cable J9283B
• HPE X242 10G SFP+ to SFP+ 7m Direct Attach Copper Cable J9285B

and then, on Comware side, you would just use this command (transceiver phony-alarm-disable) if the Switch doesn't recognize properly the HPE X242 SFP+ DAC on its side.

[*] I've to say that actually, with recent ArubaOS-Switch releases (16.02 branch onward), there is a command to overcome the 3rd party transceivers - as they can be categorized, so unsupported - "not recognized as genuine" issue...so the discussion I linked could be not true anymore now.

The contrary could be true too: using supported SFP+ DAC Cables on Comware side and then, on ArubaOS-Switch side, use the provided command to admit the usage of non HP genuine Transceivers as the HPE X242 FlexNetwork DAC Cables will be seen by the Aruba switch:

• HPE FlexNetwork X240 10G SFP+ to SFP+ 0.65m Direct Attach Copper Cable JD095C
• HPE FlexNetwork X240 10G SFP+ to SFP+ 1.2m Direct Attach Copper Cable JD096C
• HPE FlexNetwork X240 10G SFP+ to SFP+ 3m Direct Attach Copper Cable JD097C
• HPE FlexNetwork X240 10G SFP+ to SFP+ 5m Direct Attach Copper Cable JG081C
