HP 5820AF-24XG and HP 6120XG DAC question

Hi,

 

I need to connect a HP 5820AF-24XG and HP 6120XG switches via DAC cables.

 

According to the manuals these are the supported cables:

 

5820:

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

 

6120XG:

HP BladeSystem c-Class Small Form-Factor Pluggable .5m 10GbE Copper Cable 487649-B21
HP BladeSystem c-Class Small Form-Factor Pluggable 1m 10GbE Copper Cable 487652-B21
HP BladeSystem c-Class Small Form-Factor Pluggable 3m 10GbE Copper Cable 487655-B21
HP BladeSystem c-Class Small Form-Factor Pluggable 5m 10GbE Copper Cable 537963-B21
HP BladeSystem c-Class Small Form-Factor Pluggable 7m 10GbE Copper Cable 487658-B21

HP X242 SFP+ SFP+ 1m Direct Attach Cable J9281B
HP X242 SFP+ SFP+ 3m Direct Attach Cable J9283B
HP X242 SFP+ SFP+ 7m Direct Attach Cable J9285B
HP X242 SFP+ to SFP+ 10m Direct Attach Copper Cable J9286B
HP X242 SFP+ to SFP+ 15m Direct Attach Copper Cable J9287B

 

 

Not a single common one... Is there anything I could do, short of using optical SFPs?

Hi Tamas,

Please don't take this as authoritative (I'm definitely not an expert), but I've successfully used Dell-rebadged Cisco SFP+ direct attached cables with our 5820X stack. So I would be inclined to just get an appropriate direct attach cable supported by the 6120XG and give it a shot; they're not so terribly expensive that it's a big problem if it doesn't work. In my (limited) experience, Comware switches have no problem with third party SFPs, whether 1G or 10G.

Of course, if this is pre-purchase for a big project, then it's a bit trickier, but in that case you're probably working with a reseller who can get their pre-sales folks to validate your BoM.

5820 cables (X240) are not supported with the 6120XG. Please take one of the cables listed under 6120XG header, they work with 5820.

 

10m (J9286B) and 15m DAC (J9287B) will be end of sale.

Hi

 

I allways use the X240 cable. It works in any constellations.

 

But yes, there is no supported solution. But not supported doesn't mean not working. :-)
